Mailshake is a sales engagement platform designed to make cold outreach simple and effective for modern B2B teams. The product centers on sending personalized cold emails at scale, then layering in phone calls and LinkedIn touches so reps can manage full multi-channel sequences from one place. With built-in deliverability tools, email warmup, templates, and AI-assisted writing, Mailshake focuses on helping users land more messages in the inbox and convert replies into qualified meetings.
Founded in 2015 and headquartered in Austin, Texas, Mailshake is a privately held, bootstrapped company led by founders Bob Senoff, Sujan Patel, and Colin Mathews. The team has deep experience in SaaS, marketing, and outbound sales, and has grown Mailshake to tens of thousands of users worldwide without traditional venture funding. The company emphasizes ease of use and rapid time to value—teams can typically launch their first campaigns within a day, with little to no IT involvement.
The product includes capabilities for automated multi-step sequences, A/B testing, an integrated power dialer, LinkedIn automation, lead scoring, and pipeline-focused analytics. Additional modules like Data Finder (for business contact discovery) and Ready-to-Use Mailboxes (for quickly spinning up sending identities) help customers scale outreach while protecting domain reputation. Native integrations with major CRMs and scheduling tools, along with extensive connectivity via Zapier, Integrately, and Make, ensure Mailshake can fit into existing sales tech stacks.
Mailshake’s market position is strongest among SMB and mid-market sales teams, agencies, and consultants that need powerful outbound capabilities without the complexity or cost of heavyweight enterprise sales engagement platforms. The company competes with tools like Apollo.io, lemlist, Woodpecker, and Outreach, differentiating with its focus on deliverability, simplicity, and hands-on training and support rather than attempting to be an all-in-one CRM or marketing automation suite.
