About ClearBounce — Email Verification Built for Accuracy

What we do

ClearBounce brings together bulk list verification, a real-time API, form protection and deliverability monitoring in one place — the four things a sender actually needs to keep a list healthy.

Behind it runs a probe network across Europe, the United States and Asia-Pacific, because asking mailbox providers about millions of addresses from a single machine does not work for long.

Every result comes back labelled: deliverable, undeliverable, risky or catch-all. Nothing is rounded up to sound better than it is.

What the data looks like

75.9%

of the addresses we checked in H1 2026 were actually deliverable. Nearly one in four was not.

80%

of the lists we processed were at least a fifth unusable — most owners had no idea.

What we stand for

Verification is a network, not a lookup

A single SMTP question answered from a single machine stops working at scale. Ours runs as a layered system — DNS and MX intelligence, provider-specific logic, AI-driven pattern analysis and a probe network spread across Europe, the United States and Asia-Pacific.

We do the work on catch-all domains

Catch-all servers accept every address on sight, and most tools take that at face value and report deliverable. We keep probing — from separate IPs, with longer windows — to tell a genuine mailbox from an accept-all wall or a tarpit, and we say which one we found.

Your data is never for sale

We verify your list and hand it back. No reselling, no enrichment, no quiet data siphon — GDPR and CCPA ready, with a data-processing agreement when procurement asks for one.

The people behind ClearBounce

A small team that has spent years on the unglamorous side of email: bounce codes, SMTP timeouts and sender reputation.

Started ClearBounce after watching good campaigns fail for reasons nobody could see — a list full of addresses that had quietly stopped existing. Still reads the verification logs.
