Email verification · built in
Clean your list before it burns your reputation.
A dual-engine check — Reoon plus your own Amazon SES — catches invalid, disposable, spam-trap, and catch-all addresses before they bounce. Verify one contact or a whole list, and bad addresses are blocked automatically at send time.
Credit-based. Plans include a monthly verification allowance — top up any time.
Honest results
Every address, sorted into something you can act on.
No vanity “valid” stamp on addresses we can't actually prove. Three honest buckets — safe to send, hard-blocked, or flagged for your judgement.
Mailbox exists and accepts mail. Cleared to send.
No such mailbox. Sending here bounces and hurts your domain.
Domain accepts everything — we can't prove the box is real. Flagged, not blocked.
Throwaway/burner domains. Filtered before they ever cost you a send.
Known trap addresses. The fastest way to a blocklist — auto-removed.
The server wouldn't give a straight answer. Surfaced so you decide.
How it works
Verify, sort, send — without leaving the platform.
- 1
Bring a list
Verify one contact inline, a selection, or a whole list. CSV imports can be checked on the way in.
- 2
Dual-engine check
Reoon runs the primary verification; if you have Amazon SES connected, its result cross-checks the ambiguous cases for extra confidence.
- 3
Auto-sorted results
Bad addresses are marked for removal or suppression, risky ones get a yellow flag, clean ones stay. Bulk-move or bulk-suppress in one click.

Send clean
Invalid, disposable, and spam-trap addresses are hard-blocked at send time automatically — verification isn't a separate tool you forget to run.

A verifier you can't forget to run.
Standalone verifiers are a separate login, a separate bill, and a step that's easy to skip the day you're in a hurry. Here, verification status lives on the contact and the sender enforces it — invalid, disposable, and spam-trap addresses are blocked at send time whether or not you remembered to clean the list. Protected reputation is the default.
Honest answers about what we can and can't prove.
We flag what we can't verify instead of guessing. Here's exactly how it works.
Every address runs through Reoon, our platform verifier, which performs syntax checks, MX/domain resolution, disposable-domain detection, and SMTP-level mailbox probing. When your workspace has Amazon SES connected, SES is used to cross-check the ambiguous results — so a "catch-all" or "unknown" gets a second opinion instead of a guess. We don't publish a single headline accuracy number because real-world accuracy depends on the recipient domains in your list, and we'd rather not promise a figure we can't guarantee for your data.
Yes — catch-all domains are detected and labelled "risky" rather than silently passed as valid. A catch-all server accepts every address, so no verifier on earth can prove a specific box exists. We flag it honestly so you can decide whether to send, instead of charging you for a "valid" result we can't stand behind.
Both. Verify a single contact inline, a multi-select of contacts, or kick off a background job against an entire list. Large lists process as a job so you can keep working; results land in a report you can act on in bulk.
Verification runs on credits — you pay per address checked, and a disposable-domain pre-filter means obvious throwaways are caught before they spend a full credit. Plans include a monthly allowance; top-ups are available. See the pricing page for current credit allowances.
Your call. From the results screen you can bulk-remove them from a list, bulk-add them to your suppression list, or move them elsewhere. Separately, invalid / disposable / spam-trap addresses are hard-blocked at send time regardless — so even an unverified bad address can't quietly torch a campaign.
No, and that's the point. Most teams buy a standalone verifier, run it once, and forget. Here, verification status lives on the contact and is enforced by the sender itself — clean lists and protected reputation are the default, not a chore.
