Key Takeaways
- Email remains the highest-ROI digital channel, driving an average of $36–$42 in revenue for every $1 spent, and B2B programs that are run professionally can outperform that benchmark.
- Using a B2B email marketing service lets your SDRs and AEs stay focused on conversations and closing, while specialists handle list building, copy, deliverability, and testing.
- Roughly 73% of B2B buyers prefer sellers to contact them via email, making it the single most welcomed outbound channel for starting and nurturing conversations.
- Agencies that live and breathe email are far better equipped to manage technical details like domain warming, authentication, and list hygiene, which directly impact inbox placement and reply rates.
- Leveraging an expert B2B email partner gives you faster ramp time, easier scaling, and clearer reporting, so you can model cost per meeting, cost per opportunity, and pipeline contribution with confidence.
- Personalized, segmented campaigns managed by specialists consistently beat generic blasts, with segmented programs driving materially higher opens, clicks, and conversions.
- Bottom line: if outbound email is a core part of your pipeline, a B2B email marketing service is usually cheaper, faster to ramp, and more predictable than trying to DIY everything in-house.
In a world where 73% of B2B buyers prefer vendors to reach out via email, getting your outbound program right is non-negotiable. A specialized B2B email marketing service can help you tap into email’s 3,600-4,000% average ROI, while avoiding the technical, data, and resourcing headaches that sink most DIY efforts. This guide breaks down 10 concrete benefits, with benchmarks, examples, and practical advice for modern sales teams.
Introduction
If you are running B2B sales in 2025, you are living in email.
Your buyers may dodge cold calls and ghost LinkedIn messages, but they still live in their inboxes. Recent research shows that 73% of B2B buyers prefer vendors to contact them via email, making it the single most welcomed channel for starting a conversation. Omnisend
At the same time, email is still the ROI king. Multiple analyses put email marketing returns between $36 and $42 for every dollar spent, with B2B programs performing particularly well. ProspectWallet This is why 71% of B2B marketers use email newsletters to nurture leads and 81% rely on email as their primary content distribution channel. Omnisend
Here is the catch: running high-performing B2B email at scale is hard. Deliverability keeps tightening, data decays monthly, and SDR teams are already stretched thin. That is where B2B email marketing services come in.
In this guide, we will break down:
- Why email still rules B2B pipeline
- 10 concrete benefits of using B2B email marketing services
- When it makes sense to outsource vs. build in-house
- How to choose the right partner
- How all of this plays out for your SDRs, AEs, and revenue targets
You will walk away with a practical framework for treating email like a serious sales channel, not just a monthly newsletter.
Why Email Still Rules B2B Pipeline
Before we talk about services and outsourcing, let us level-set on why email is still worth fighting for.
Email’s ROI Is Still Ridiculous
Across multiple studies, email continues to deliver some of the highest returns of any digital channel:
- Average ROI between $36 and $40 per $1 spent, or 3,600-4,000% returns. Omnisend
- Some analyses find ROIs up to $42 per $1, with certain verticals (like software and tech) hovering around $36. ProspectWallet
- Automated workflows often deliver 30x higher returns than one-off campaigns. ProspectWallet
For B2B specifically, email is not just a marketing channel; it is a sales channel. Studies show that email was ranked as the second most effective sales and marketing lead source in B2B at 32% of respondents. Omnisend
Your Buyers Actually Prefer Email
On the buyer side, the story is even clearer:
- 73% of B2B buyers say they prefer sellers to contact them via email. Omnisend
- Other surveys put the preference for email as a communication method for business in the 60-80% range, well ahead of calls or social. BookYourData
So while everyone loves to claim ‘people do not read email anymore’, the data says the opposite. They read plenty of email. They just do not read irrelevant, low-value email.
Automation, Segmentation, and Personalization Have Changed the Game
Email is no longer about blasting a monthly update. The performance gap between mature and immature programs is huge:
- Automated emails see around 48% open rates and 4.7% click rates, while regular campaigns average closer to 38% opens and 1.3% CTR. UseBouncer
- Segmented and behavior-triggered campaigns generate up to 10x the revenue of generic batch sends. Omnisend
- Personalized emails can deliver roughly 29% higher open rates and 41% more clicks than non-personalized versions. UseBouncer
The upside is massive-but only if you have the time, skills, data, and infrastructure to execute.
That is why more revenue teams are leaning on B2B email marketing services to run this motion professionally.
10 Benefits of Using B2B Email Marketing Services
Let us break down the big reasons B2B teams bring in specialized email partners instead of trying to duct-tape everything in-house.
1. Predictable, High ROI Without the Overhead
Building a serious email program internally means more than buying a tool. You need:
- Clean, accurate data and list-building workflows
- Skilled copywriters who understand B2B value props and objections
- Technical expertise for deliverability and authentication
- Analysts to monitor performance and run experiments
A B2B email marketing service spreads those fixed costs across many clients. You effectively rent a fully built email machine at a flat monthly cost instead of assembling a franken-stack yourself.
Given email’s baseline ROI of roughly $36–$40 per $1 spent, even modest gains in reply rate or conversion can translate into a lot of extra pipeline. ProspectWallet When an agency can launch faster and run leaner than an in-house team, your cost per meeting and cost per opportunity usually come down.
2. Faster Ramp and Easy Scaling
Hiring and ramping internal SDRs and email operators is slow. Between recruiting, onboarding, tech setup, and experimentation, you can easily burn 3-6 months before the motion stabilizes.
A good B2B email marketing service:
- Onboards in weeks, not quarters
- Brings pre-tested frameworks for cadences and messaging
- Has proven playbooks for common ICPs and verticals
Need to double outreach into mid-market accounts next quarter or test a new geo? Instead of going back to HR and finance to open headcount, you tweak the scope with your provider.
SalesHive, for example, offers different packages that execute 150-500 touches per day per pod across phone and email, which lets clients quickly scale up or down based on pipeline goals without rebuilding the team every time.
3. Stronger Deliverability and Technical Foundations
Most internal teams underestimate how much plumbing sits underneath successful email:
- Domain strategy (main vs. lookalike domains)
- DNS records (SPF, DKIM, DMARC)
- IP and domain warming
- Inbox placement monitoring
- Bounce and spam complaint management
In 2024, average deliverability hovered around 83%, meaning nearly one in six marketing emails never reached the inbox. UseBouncer For SaaS senders and aggressive outbound programs, it can be worse.
B2B email marketing services live in this world every day. They know how to:
- Set up sending from lookalike domains so your primary domain’s reputation is protected
- Authentically warm new domains and inboxes before hitting scale
- Keep bounce rates below 2% and spam complaints around 0.1% or less
- Adjust sending patterns and segmentation when inbox placement dips
SalesHive, for instance, spins up ‘lookalike’ domains for each client and runs its proprietary SHWARMING warm-up process so volume can scale without dumping cold traffic onto the main corporate domain.
When deliverability is handled, your team can focus on message-market fit instead of wondering why nothing is landing.
4. Access to Specialized Strategy and Copywriting
Writing copy that a CFO, a VP of Operations, and a DevOps lead will all respond to is not the same as writing blog posts. Great outbound email:
- Nails the prospect’s current pain in 2-3 short sentences
- Signals clear relevance (industry, tech stack, trigger event)
- Offers a concrete next step, not a vague ‘pick your brain’ ask
The catch? Your best closers are rarely your best writers, and your content marketers often write too long and fluffy for cold outbound.
B2B email marketing services employ specialists who write and test subject lines and body copy full time. They also cross-pollinate: what works for a mid-market SaaS security tool might also work, with tweaks, for a healthcare compliance platform.
Agency teams will typically:
- Build a messaging matrix by persona and use case
- Test 5-10 subject line frameworks per segment
- Rotate value props (risk, revenue, efficiency, compliance) to see what lands
They are not guessing; they are running controlled experiments across thousands of sends a week and doubling down on what moves reply and meeting rates.
5. True Personalization and Segmentation at Scale
Everyone knows personalization matters, but few teams go beyond first-name merge tags.
The data is clear:
- Personalized emails deliver roughly 29% higher open rates and 41% higher click-throughs than generic ones. UseBouncer
- Segmented campaigns can boost revenue by as much as 760% over unsegmented sends. UseBouncer
The challenge is bandwidth. Having SDRs manually research every account and craft custom intros does not scale.
This is where modern B2B email services shine. The better ones use a hybrid approach:
- AI-driven research and personalization engines to pull in company news, tech stack, hiring trends, or content consumption
- Human editors to keep tone natural, accurate, and on-brand
SalesHive’s eMod engine, for example, researches each target company and prospect, then generates custom snippets that humans edit and approve, blending scale with authenticity.
That means you can send thousands of emails that feel hand-written, without burning out your SDR team.
6. Multichannel Cadences Without More Tools
Pure email plays are becoming less effective on their own. Buyers research independently, and it often takes 5+ touches across channels to get a meeting.
The best B2B email marketing services do not operate email in a silo. They orchestrate:
- Cold calls
- LinkedIn touches
into coherent cadences. A prospect might:
- Receive a short, personalized intro email
- See a LinkedIn view or connection request
- Get a follow-up email with a case study
- Receive a well-timed call referencing the previous touches
You get the consistency and volume of an automated system, with the human nuance of trained SDRs behind it. SalesHive explicitly runs blended phone-and-email programs, with US-based and Philippines-based teams executing hundreds of touches per day while a strategist manages the overall playbook.
7. Better Data, List Building, and ICP Alignment
Bad data kills outbound programs.
If your lists are built on fuzzy firmographics or scraped emails, you will see:
- High bounce rates and spam complaints
- Awful reply quality
- SDRs wasting time chasing non-ICP leads
B2B email marketing services usually have dedicated research teams and access to multiple data providers. They can:
- Build lists by tightly defined ICP (industry, headcount, funding, tech stack, geography)
- Enrich contacts with titles, responsibilities, and triggers
- Verify emails to keep bounces under control
Many agencies, including SalesHive, bundle list building into their engagements so you are not trying to bolt on yet another vendor just to get clean data.
Over time, that focus on ICP alignment shows up directly in pipeline quality-more meetings with the right people at the right accounts.
8. Stronger Lead Nurturing and Lifecycle Programs
Cold outreach is only one piece of the puzzle. B2B sales cycles are long; a lot of the magic happens in nurture.
Stats bear this out:
- 71% of B2B marketers use email newsletters to nurture leads. Omnisend
- Automated flows (welcome, re-engagement, content drips) account for a disproportionate share of email-driven revenue even though they are a small share of total volume. Omnisend
A mature B2B email service will help you design tracks for:
- New inbound leads not yet ready for sales
- Event or webinar registrants
- Closed-lost opportunities
- Target accounts showing intent but not yet engaged with sales
Instead of SDRs trying to manually ‘stay in touch’, automated email nurtures keep your brand top of mind and warm up accounts for when they are ready to talk.
9. Compliance, Risk Management, and Brand Protection
Between CAN-SPAM, GDPR, and various privacy regulations, cold email is not the Wild West anymore (and that is a good thing). The last thing you want is an SDR winging it with home-brewed lists and copy.
Email marketing services help mitigate risk by:
- Managing opt-out mechanisms and suppression lists
- Honoring regional compliance requirements
- Avoiding obviously non-compliant practices like purchased spam lists
- Monitoring complaint rates and adjusting quickly
They also bring a brand lens. A good partner will not just say ‘yes’ to aggressive copy; they will flag when tone or claims could backfire with your market.
10. Better Metrics, Forecasting, and Pipeline Visibility
Finally, a strong B2B email marketing service gives you real numbers to run the business on.
You should be able to answer questions like:
- What is our reply rate and positive reply rate by segment and persona?
- How many emails does it take, on average, to generate a meeting for each ICP slice?
- What is our cost per meeting and cost per opportunity from email?
Agencies that do this well provide dashboards that tie email activity directly to meetings and opportunities in your CRM. SalesHive, for example, integrates its AI-powered sales platform with clients’ CRMs so every call, email, and meeting can be tracked and analyzed.
When outreach is measurable at that level, you can forecast pipeline from email the same way you do from paid ads or events.
When B2B Email Marketing Services Make the Most Sense
Outsourcing is not for everyone, and it is not an all-or-nothing decision. Here are scenarios where a B2B email service is usually a smart move.
1. You Need Pipeline Faster Than You Can Hire
If you have aggressive revenue targets for the next 2-3 quarters, waiting six months for an in-house program to stabilize is risky. An experienced email service can launch in weeks and start generating replies and meetings in the first 30-60 days.
2. Your SDRs Are Buried in Non-Core Work
If SDRs are spending more time:
- Building lists in spreadsheets
- Fighting deliverability issues
- Tweaking cadences in three different tools
than actually talking to prospects, you have an efficiency problem. Offloading the heavy operational work to a specialist lets SDRs focus on conversations and qualification.
3. Your Current Email Metrics Are Flat (or Unknown)
If you do not know your reply rate, or if your meetings from email have stalled, you are probably missing tested frameworks and experimentation. Agencies live in benchmarks; they know what ‘good’ looks like in your segment and can quickly identify weak points in your current motion.
4. You Are Testing New Markets or Products
When you are expanding into a new region, vertical, or product line, you do not yet know what messaging will resonate. Working with a B2B email service that can spin up micro-tests across segments helps you find signal faster without over-committing headcount.
5. You Want Multichannel Outbound Without Building a Full SDR Org
If your AEs are doing their own prospecting and it is clearly not sustainable, but you are not ready to build a full internal SDR function, an outsourced partner can bridge the gap. Many, like SalesHive, combine email, calling, and list building under one roof so you get multichannel coverage without managing multiple vendors.
How to Choose the Right B2B Email Marketing Partner
Not all email services are created equal. Some are glorified blast shops; others behave like strategic extensions of your revenue team. Here is what to look for.
1. Strategy First, Tools Second
Ask potential partners:
- How do you define and refine ICPs?
- What does your messaging development process look like?
- How do you incorporate SDR and AE feedback into campaigns?
If they cannot speak fluently about targeting, sales qualification, and objection handling, you are likely dealing with a generic marketing vendor, not a B2B sales development partner.
2. Transparency and Reporting
You should have clear visibility into:
- Sends, opens, replies, and positive replies
- Meetings booked and show rates
- Pipeline and revenue influenced
Prefer partners who are comfortable connecting directly to your CRM and sharing dashboards, not just monthly PDF reports.
3. Deliverability Discipline
Dig into:
- Domain strategy and ownership (you should own the domains, not them)
- Warm-up processes
- List hygiene cadence
- Bounce and spam complaint thresholds
If deliverability is an afterthought, walk away.
4. People Quality and Training
Who is actually writing your emails and handling replies?
- Are copywriters and responders B2B-focused and fluent in your language and market?
- Is there a clear coaching and QA process?
- Will you have access to the humans working your account or just an account manager?
SalesHive, for example, uses US-based strategists and responders for higher-complexity programs, with Philippines-based SDRs for cost-effective volume where appropriate.
5. Ownership of Data and Assets
Make sure your contract spells out that you own:
- All prospect and customer data
- All email templates and playbooks
- All performance data and insights
That way, even if you change partners down the line, you keep the learnings.
How This Applies to Your Sales Team
Let us translate all this into the day-to-day reality of SDR managers, AEs, and revenue leaders.
For SDR/BDR Managers
A solid B2B email marketing service can:
- Feed your team with a steady stream of interested replies instead of pure cold lists
- Take the burden of list building and deliverability off your plate
- Provide tested cadences your team can mirror in LinkedIn or phone outreach
Your reps spend more time having conversations with warmed-up prospects and less time tinkering with tools.
For Account Executives
When email is run well, AEs feel the impact in their calendars and pipelines:
- More net-new meetings with real buying committees
- Better alignment between what was promised in email and what happens on the call
- Shorter cycles because the right context and value props have already been seeded via email
Instead of idling between deals or prospecting in a panic at the end of the quarter, AEs can work a more predictable flow of opportunities.
For Revenue and Marketing Leaders
At the leadership level, partnering with a B2B email marketing service gives you:
- A clearer lever for pipeline creation that you can model and forecast
- The ability to compare outbound email to other channels on cost per dollar of pipeline
- Flexibility to scale outreach up or down without hiring and firing cycles
You can move budget from low-performing tactics into a channel that is measured down to the meeting and opportunity.
Conclusion + Next Steps
Email is not going anywhere. If anything, it is getting more important as buyers increasingly prefer digital, low-friction interactions and self-education before talking to sales. But ‘send more email’ is not a strategy.
Used well, B2B email marketing services give you:
- The infrastructure (domains, tools, data) you do not have time to build
- The expertise (strategy, copy, testing) your team cannot replicate overnight
- The execution muscle (SDRs, responders, analysts) to keep outbound humming day in and day out
If email is a significant source of your pipeline-or if you want it to be-it is worth treating it like a first-class sales channel. That usually means bringing in specialists.
Your next steps:
- Audit your current email performance and infrastructure.
- Clarify your ICPs, segments, and revenue targets.
- Shortlist a few B2B email marketing services and grill them on strategy, deliverability, reporting, and how they work with sales.
- Run a 60-90 day pilot with a narrow ICP and crystal-clear success metrics.
If you would rather skip the guesswork, a partner like SalesHive-combining cold email, cold calling, list building, and SDR outsourcing-can plug directly into your revenue engine and start turning email into meetings and pipeline in a matter of weeks.
Either way, the teams that win over the next few years will be the ones who treat email as a disciplined, data-driven sales channel, not a side project. The tools and partners are out there. The question is whether you are ready to put them to work.
📊 Key Statistics
Expert Insights
Treat Email Like a Sales Channel, Not a Newsletter Tool
If your email program is owned purely by marketing, you'll usually optimize for opens and clicks instead of meetings and pipeline. Bring your sales leadership into campaign planning, define what a qualified reply or meeting looks like, and have your email service report on cost per opportunity, not just vanity engagement metrics.
Invest in Deliverability Before You Invest in More Volume
Blasting more emails through a weak technical setup is like pouring water into a leaky bucket. Make sure your provider is managing domains, authentication, warm-up, list hygiene, and spam monitoring before they scale volume. That foundation alone can swing reply rates by several percentage points, which is massive in cold outbound.
Build Cadences Around Buying Committees, Not Just Personas
In B2B, one email to 'the decision-maker' rarely moves the needle. Use your email marketing service to orchestrate sequences by buying committee: economic, technical, and end-user stakeholders, each with messaging tailored to their priorities. Then track which personas generate meetings and opportunities so you can double down on what works.
Use Agencies for Testing You'd Never Have Time to Run Internally
Most in-house teams barely test subject lines, much less full value propositions or ICP variants. A strong B2B email service will continuously A/B test angles, calls to action, and cadences across thousands of sends, then roll back winners to your program. Lean on that experimentation engine instead of guessing in a vacuum.
Align Email Outreach With SDR Call and LinkedIn Motions
Your cold email program should not live on an island. Coordinate with SDR call blocks and LinkedIn touches so prospects see a logical, cohesive sequence over 2-4 weeks. Agencies that also run calling and list building can stitch this together for you, improving conversion without tripling your management overhead.
Common Mistakes to Avoid
Treating an email agency as a pure 'blast engine' with no strategic guidance
When you just hand over a list and say 'send more emails', you get volume without relevance. That tanks reply quality, annoys your market, and can damage your sender reputation.
Instead: Choose a partner that pushes back on targeting, builds an ICP-based playbook with you, and owns testing and optimization, not just pressing send.
Optimizing for opens and click-throughs instead of meetings and opportunities
Subject lines that spike opens but attract the wrong intent clog SDR calendars with unqualified conversations and erode trust between marketing and sales.
Instead: Define revenue-focused KPIs up front: reply rate, positive reply rate, meetings booked, show rate, and pipeline created. Have your email marketing service report and optimize against those.
Ignoring deliverability and domain health until it is too late
If your domains get throttled or land on blocklists, you can lose inbox placement across the entire company, not just outbound. Recovery can take months.
Instead: Insist your provider manages lookalike domains, authentication (SPF, DKIM, DMARC), warm-up, and regular list cleaning. Monitor bounce and spam-complaint rates as leading indicators.
Letting the agency own data and messaging with no internal documentation
When you do not own your lists, copy, and learnings, you are stuck if you ever switch vendors or bring functions in-house, and you lose institutional knowledge about what resonates.
Instead: Require that all data, templates, and analytics are stored in shared systems or exported regularly. Run joint reviews so your team understands what is working and why.
Running email totally separate from SDRs and AEs
If email sequences do not align with what SDRs say on the phone or what AEs promise on demos, prospects experience a disjointed journey and qualification breaks down.
Instead: Have your B2B email marketing service collaborate directly with SDR leadership. Share call recordings, objections, and customer language so email copy and talk tracks reinforce each other.
Action Items
Map outbound email metrics directly to your revenue funnel
Define benchmarks for opens, replies, positive replies, meetings, opportunities, and closed-won influenced by email. Ask your email marketing service to structure reporting around these stages so you can calculate cost per meeting and cost per opportunity.
Audit your current email infrastructure and sender reputation
Before scaling volume, have your provider run checks on SPF, DKIM, DMARC, domain age, spam listings, bounce rates, and complaint rates. Fix issues and warm new domains gradually instead of dumping cold lists into your main domain.
Segment your B2B audience into at least 3–5 concrete ICP slices
Work with your agency to create segments by firmographic and technographic traits (industry, company size, tech stack, funding stage). Build tailored sequences for each instead of a single 'catch-all' campaign.
Implement at least one automated nurture track for non-responsive or early-stage leads
Ask your provider to set up a low-frequency drip that educates and adds value over 60-90 days. This keeps cool leads warm without overwhelming SDRs with manual follow-ups.
Create a monthly joint review between sales leadership and your email partner
Review performance by segment, persona, and messaging angle. Bring in anecdotal feedback from SDRs and AEs, then agree on 1-3 specific tests or tweaks for the next month.
Standardize how meetings sourced from email are tagged in your CRM
Make sure every meeting booked from email has a clear campaign and source tag. This allows you to compare the performance of your email marketing service against other channels on an apples-to-apples basis.

❓ Frequently Asked Questions
What exactly is a B2B email marketing service in a sales development context?
In B2B sales development, a email marketing service is usually a specialized agency or provider that handles the nuts and bolts of outbound and nurture email for you. That includes list building and enrichment, copywriting, sequencing, campaign setup, deliverability management, and performance reporting. The best providers integrate tightly with your SDRs, AEs, and CRM so email outreach feeds qualified conversations and pipeline, not just 'marketing engagement'.
How is using a B2B email marketing service different from just buying email software?
Buying software gives you tools; a service gives you people, process, and accountability. Platforms will send whatever you load into them, but they won't define your ICP, write copy that matches your sales motion, or troubleshoot deliverability issues. A good B2B email marketing service brings strategists, copywriters, analysts, and deliverability experts who run campaigns day in and day out, then sit down with you to review meetings and pipeline impact.
Isn't email getting less effective with all the noise in inboxes?
Despite the noise, email is still one of the best-performing B2B channels. Multiple analyses put email ROI in the $36–$40 range per $1 spent, and some sectors see even higher returns. Automated flows and segmented, personalized campaigns significantly outperform generic blasts. The teams that struggle are usually under-investing in strategy, data, and deliverability, not victims of a 'dead' channel.
When does it make sense to outsource email instead of hiring more SDRs?
Outsourcing starts to look very attractive when you need more top-of-funnel coverage but do not have the time, budget, or management capacity to hire and ramp a full SDR pod. A good email service can often spin up in a few weeks, cover multiple market segments, and share infrastructure (data, domains, automation, analytics) across clients, which makes your effective cost per meeting lower than adding headcount.
How do I make sure an email marketing agency does not harm our brand or domain reputation?
Start by vetting their deliverability practices: ask how they handle domains, authentication, warming, list hygiene, and spam monitoring. Review sample copy to ensure tone and claims match your brand. During the engagement, insist on transparent reporting, shared access to sending domains, and regular reviews of complaints and unsubscribes. You should always own the domains and data they use on your behalf.
What KPIs should I hold a B2B email marketing service accountable for?
At a minimum, track open rate, reply rate, positive reply rate, meetings booked, meeting show rate, and pipeline created. From there, calculate cost per meeting and cost per qualified opportunity. For ongoing optimization, also track bounce rate, spam-complaint rate, and performance by segment and persona so you can see where to double down and where to pivot.
Can a B2B email marketing service help with lead nurturing, or is it just for cold outreach?
A strong provider should handle both. In fact, many of the biggest gains come from nurturing: educating early-stage leads, re-engaging closed-lost opportunities, and staying in touch with accounts that are not yet ready to buy. Automated nurture flows and newsletters are where email's ROI really compounds over time for B2B teams.
How long does it usually take to see results from an outsourced B2B email program?
Most teams start to see meaningful reply volume and meetings within the first 30-60 days, assuming lists and messaging are aligned. That first phase is usually about validating ICP, angles, and deliverability. Predictable, model-able performance typically emerges over 90-120 days once the provider has enough data to double down on winning segments and copy.
