About DeBounce

DeBounce is a specialist email validation and verification platform designed to help businesses keep their mailing lists clean, deliverable, and compliant. It allows users to upload large CSV/TXT lists or connect directly to ESPs and CRMs to detect invalid, disposable, spam-trap, role-based, and risky email addresses before campaigns go out. With a 4.5/5 rating on G2 and 4.7/5 on Capterra, plus an excellent Trustpilot score, DeBounce is positioned as a high-value, budget-friendly alternative to better-known enterprise tools.

The product portfolio spans bulk list cleaning, automated list monitoring, a real-time email validation API, a JavaScript widget for website forms, a Lead Finder tool for discovering valid addresses from names and domains, and optional data enrichment via reverse email lookup. Its engine combines DNS and MX checks, SMTP and mailbox verification, catch-all domain analysis, disposable detection, typo correction, and anti-greylisting technology to minimize “unknown” results. Credits are usage-based, never expire, and include access to all features, including API usage, list monitoring, and integrations.

Founded in 2018 and headquartered in Pune, Maharashtra, India, DeBounce operates as a small, privately held company with a lean team (1–10 employees) focused on a single core product. The company emphasizes transparent pricing, self-service onboarding, and a developer-friendly stack with comprehensive API documentation and multi-language examples. It has grown to serve over 15,000 businesses across more than 180 countries, including recognizable brands such as Siemens, Cornell University, Samsung, Western Digital, and Mobitek.

In the email verification market, DeBounce competes with vendors like ZeroBounce, NeverBounce, Clearout, Emailable, and Bouncer. Its main differentiators are very low per-email costs, pay-as-you-go credits that never expire, and a tight set of practical features tailored to marketers and sales teams who need reliable list hygiene rather than a broad deliverability suite. Independent tests and some reviews suggest that accuracy and speed lag a bit behind the very top-tier providers, but for many small and mid-sized businesses DeBounce offers an attractive balance of price, features, and real-world performance.

Pros & Cons

👍 Pros

  • Very affordable, pay-as-you-go pricing with credits that never expire and competitive per-email costs.
  • Simple, intuitive dashboard and workflow that make bulk uploads, validation, and exports easy even for non-technical users.
  • Good real-world accuracy for most lists, with a published deliverability guarantee around the high-90% range.
  • Broad integration coverage with major ESPs and tools like Mailchimp, HubSpot, WordPress, Zapier and others, plus a native Clay integration referenced by users.
  • Real-time API and JavaScript widget enable validating emails at the point of capture to keep bad data out of CRMs and marketing tools.
  • Automatic deduplication, spam-trap and disposable detection, and strong catch-all handling improve list quality beyond simple syntax checks.

👎 Cons

  • Bulk validation can be slow on large lists compared with some competitors, with several users reporting long turnaround times.
  • Independent tests and some reviewers report lower accuracy on difficult domains and catch-all addresses versus top-tier providers.
  • Support is primarily email-based; a number of reviews mention slow, unresponsive, or unhelpful support in edge cases.
  • Validated list data is retained for a relatively short time (often around 7 days), which requires timely downloading of results.
  • A minority of users integrating via certain CRMs have reported issues such as contacts being incorrectly flagged as opted out, requiring manual remediation.

FAQ

What is DeBounce?

+

DeBounce is a cloud-based email validation and verification platform that helps businesses clean and maintain healthy email lists. It analyzes each address using DNS and MX checks, SMTP and mailbox verification, disposable and spam-trap detection, typo correction, and catch-all analysis. Users can upload lists for bulk cleaning, connect their ESP or CRM for ongoing list monitoring, or embed DeBounce via API and JavaScript widgets to validate emails in real time at the point of capture.

How much does DeBounce cost?

+

DeBounce uses a usage-based, pay-as-you-go pricing model. Credits start at about $10 for 5,000 verifications, with larger packs such as $50 for 50,000, $90 for 100,000, and $500 for 1,000,000 verifications. The effective price per email decreases as you buy more credits, and credits never expire. All plans include the full feature set, including bulk validation, the API, JavaScript widget, integrations, and list monitoring. New users also receive free test credits to try the service before purchasing.

What are the main features of DeBounce?

+

Core DeBounce features include bulk email list validation, a real-time email verification API, a JavaScript widget for validating form submissions, and automated list monitoring that keeps ESP lists clean on a daily basis. It also offers catch-all domain verification, disposable and spam-trap detection, anti-greylisting technology, free deduplication, data enrichment via reverse email lookup, and flexible export options. Integrations with major ESPs and CRMs let users plug DeBounce directly into their existing marketing and sales stacks.

Who are DeBounce's main competitors?

+

DeBounce operates in a competitive email verification market alongside vendors such as ZeroBounce, NeverBounce, Bouncer, Clearout, Emailable, Kickbox, Email List Verify, and others. Many of these tools offer similar core capabilities - bulk and real-time validation, APIs, and integrations - but differ in price, speed, accuracy, analytics, and the breadth of additional deliverability features. Buyers often shortlist DeBounce alongside these alternatives when evaluating email hygiene solutions.

Is DeBounce good for small businesses?

+

Yes. DeBounce is particularly well-suited to small businesses and startups because of its low entry price, non-expiring credits, and simple, self-service onboarding. Most reviews on platforms like G2 and Capterra come from small-business users who highlight its ease of use, affordability, and ability to significantly reduce bounce rates. While very large enterprises or teams needing advanced deliverability analytics may prefer higher-end platforms, small and mid-sized organizations looking for straightforward, budget-friendly email verification are an excellent fit for DeBounce.
