Verimail

Email verification that shows its work

Email verification service that queries each address's mail server (SMTP RCPT TO) to determine whether the mailbox exists, returning one of four verdicts — deliverable, undeliverable, risky, unknown — with a reason code, suggested action, and optional SMTP evidence. Supports CSV list uploads and a real-time HTTP API. Unknown results, duplicates, and syntax errors are not billed.
