Email verifier

Email verifier — only pay for emails that work.

Clean your list with SMTP plus platform-level verification (Microsoft, Google, and social-signal probes). Catch-alls are labeled free, and you never pay for an invalid result.

Most verifiers wave catch-alls through — then you eat the bounce.

A verifier that marks every catch-all as "valid" is just moving the bounce downstream, onto your domain. SendEmAll runs SMTP verification first, then escalates catch-alls and timeouts through Microsoft, Google and social-signal checks — so "valid" actually means deliverable.

How it works

Three steps.

01

Upload or connect

Paste addresses, upload a CSV/XLSX (we auto-map your columns), or verify inline as you build a list.

02

Multi-layer verification

SMTP first, then a platform-specific cascade for catch-alls — Microsoft and Google account-level checks, plus multi-signal social probes.

03

Keep the valid ones

Export a clean list with clear valid / accepts-all / invalid labels. You're only billed for verified, valid emails.

Pay per valid result

Catch-alls, invalid and risky addresses are labeled and free — a credit is only spent when an email verifies valid.

Catch-alls free

Accepts-all addresses are clearly labeled in their own column and never counted against your quota.

Bulk + API

Verify lists of any size, or wire real-time verification into your product via the REST API.
