Show HN: Free DMARC Checker – Verify your domain meets sender requirements

[slonik]

Mailbox providers are tightening up sender requirements for authentication, making DMARC crucial for bulk sending.

I made a DMARC validator where you can check out whether your setup is valid or needs any improvements.

It looks up _dmarc.<domain>, parses the TXT record, and displays policy (p/sp), alignment (adkim/aspf), reporting (rua/ruf), and options like pct, fo, ri, etc. It also gives you useful recommendations about your DMARC and helps you resolve potential issues.

It’s free and no sign-up.
