Show HN: Open-Source Email Verifier

4 points by marcushyett 2 months ago · 0 comments · 1 min read

got tired of paying for email verification saas like usebouncer.com, expensive at scale and often say emails are valid when the server sends accept to anything.

built a simple npm package that does format + dns + smtp checks, plus detects those catch-all domains.

  npx email-verifier-check check user@example.com
