SMTPing Email Verifier

ChatGPT plugin

Stop bad emails before sending

View in ChatGPT directory

SMTPing is an email verification tool: it checks whether email addresses are real, safe and deliverable before you send. Every address gets one of 13 verdicts in 3 bands: safe (send), avoid (remove) or judgement (your call). SMTPing flags 150M known spamtraps, 70M complainers, 2M+ spambots and bot clickers, and 3,500+ disposable domains monitored daily.

What you can do:

  • Verify one address and get its verdict with a one-line explanation.
  • Verify a list of up to 100,000 addresses as one bulk job, then fetch the results.
  • Check one address against a single threat list (spamtrap, disposable, spambot, complainer).
  • See your remaining credit balance.

For marketers, sales teams and developers who want to cut bounces and protect sender reputation. Requires a SMTPing account: you connect with your API key on the SMTPing consent page. SMTPing only verifies addresses: it does not send email, find addresses or edit your contacts.
