Show HN: Email Verifier CLI/Library(github.com) friend and i were curious what's actually involved in email verification services like usebouncer.com. turns out the basics aren't that complicated. vibe coded a simple npm package in (mostly) one shot that does: - syntax validation - mx record lookup - smtp mailbox check (without sending emails) - catch-all domain detection
https://github.com/yolodex-ai/reachableworks as a library too:
bouncer probably does way more, feedback welcome. |
