Email Authentication Isn't Optional Anymore
Google and Yahoo now require DMARC, SPF, and DKIM for bulk senders. Without all three, your messages land in spam or get rejected entirely.
SPF declares which servers can send as you. DKIM proves messages haven't been tampered with. DMARC ties it together and tells receivers what to do when checks fail. Together, they stop domain impersonation.
The problem? Each protocol has its own DNS records, syntax, and failure modes. One misconfigured SPF mechanism, one expired DKIM key, or one misaligned DMARC policy can break legitimate email.
That's what these tools are for. Check your DMARC, SPF, or DKIM record now, or create a DMARC or SPF record from scratch.
