Validate every email address before you send
The Email Verifier agent checks every contact's email address with MX lookup, SMTP verification, and catch-all detection — protecting your sender reputation by preventing bounces before they happen.
Checks DNS records to confirm the recipient's mail server exists and accepts connections.
Performs mailbox-level verification without sending an email to confirm deliverability.
Identifies domains that accept all addresses — flagging them as higher risk for bounces.
Verifies thousands of addresses in parallel with rate limiting to respect provider limits.
Import your contact list or let the Lead Finder feed verified leads.
MX lookup confirms the domain's mail server is active.
SMTP handshake verifies the specific mailbox exists.
Results are tagged: valid, invalid, risky, or catch-all.
