Email Verification Has Evolved.
Basic checks like syntax validation or domain existence are no longer enough — especially in B2B environments dominated by catch-all and accept-all domains.
Real accuracy today comes from real-time SMTP verification. And doing that reliably is both a logic problem and an infrastructure problem.
This is why no2bounce acquired Reacher.
The Real Problem With Email Verification Today
Modern verification requires connecting directly to mail servers to determine whether an inbox can receive messages.
But SMTP servers actively defend themselves against high-frequency requests, repeated traffic from the same IPs, and enumeration-like behavior.
As a result, most tools fail not because of bad logic, but because they lack the infrastructure to run verification reliably at scale.
What Reacher Brings
Reacher was built with principles we strongly believe in:
- Open-source email verification API
- Self-hosted by default — your email lists never leave your environment
- 10× cheaper at scale compared to closed verification tools
- Real-time SMTP verification — no historical or guessed data
- Stateless, horizontally scalable architecture
- Advanced detection for MX, MTA, hard bounces, catch-all, disposable, and role-based emails
Reacher solves how verification should work — clearly, transparently, and correctly.
What no2bounce Adds
Verification accuracy breaks down at scale without the right infrastructure. no2bounce provides the missing layer:
- Stable SMTP responses at high volume
- Higher confidence results for catch-all domains
- Enterprise-ready performance and compliance
- Deliverability intelligence built for real-world B2B data
no2bounce solves how verification should run in production.
Why This Acquisition Matters
By bringing Reacher and no2bounce together, we now own the entire verification stack:
- Reacher → Transparent, real-time verification logic
- no2bounce → Infrastructure, scale, and reliability
This allows us to deliver higher accuracy at scale, fewer "unknown" results, predictable performance on large datasets, lower operational cost without sacrificing quality, and faster innovation without third-party dependency.
Introducing no2bounce Version 1.4 — Now Live
The acquisition is not just a strategic move. It is a product milestone.
No2bounce Version 1.4 is now live — and it is the first release to reflect what this union makes possible fully. The platform has been completely revamped, with Reacher's verification engine integrated at its core. This is not a bolt-on feature or a surface-level update. Reacher's logic now runs natively within no2bounce, powering every verification request with real-time SMTP precision, backed by our infrastructure layer.
What's new in v1.4?
- Reacher fully integrated: Real-time SMTP verification now runs natively across the entire no2bounce platform
- Revamped product experience: A redesigned interface built for speed, clarity, and ease of use
- Unified verification stack: One platform, one core engine, end-to-end control
- Enhanced accuracy on catch-all domains: The most significant improvement our users will notice immediately
- Improved API performance: Faster response times and more consistent results at scale
Version 1.4 is available to all No2Bounce users today — no migration required.
One Ecosystem. Multiple Ways to Use It.
Different teams have different needs:
- Developers → Self-host Reacher
- Growth teams → Managed verification via no2bounce
- Enterprises → Global scale with no2bounce infrastructure
All powered by the same verification core. All available now.
Closing Thoughts
This acquisition is not about expansion for the sake of growth.
It is about building email verification the right way: accurate, scalable, transparent, and honest, especially where it is hardest.
Version 1.4 of no2bounce is our first proof point. There is more to come.
Because every email address matters.
