Email Validator API
Stop fake emails from breaking your signup flow
Validate any email in real time with a 3-step check: syntax, MX record, and SMTP handshake. No email sent — we verify the mailbox actually exists. Catches typos (gmial.com), disposable domains (mailinator), and dead addresses before they hit your database. Free tier: 1,000 validations/month. No API key. Pure Python, GDPR-friendly.
Built this after my own signup forms kept collecting fake emails from bots. Tried every regex-only validator out there — they all let obvious fakes through. So I built one that actually talks to the mail server.
Now handling thousands of validations daily. Adding typo-suggestions next. Feedback welcome!
