Email Verifier
Run a real-time syntax, MX, disposable and role-mailbox check on any email address and get an instant deliverability score.
How email verification works
We run four fast checks: RFC-style syntax validation, an MX lookup on the domain, a disposable-provider match, and a role-mailbox detection (info@, support@, sales@, …). The combined deliverability score helps you decide whether to send.
Why bounces matter
Mailbox providers measure your bounce rate as a primary trust signal. A campaign with more than 5% bounces will get throttled or filtered to spam. Verifying upfront keeps your reputation clean.
What we don't do
We don't perform live SMTP RCPT probes from this free tool — providers like Google now return false positives for most accept-all domains. Icemail uses a multi-provider waterfall and catch-all detection on every enrichment.
Ship cold email that actually lands
Icemail bundles dedicated infrastructure, warmup, enrichment, and a unified inbox so your deliverability stays green.
