Verify a sender domain

Gmail and Yahoo now require SPF, DKIM, and DMARC for any bulk sender. Without them, you land in spam or get blocked outright.

1. 1
   Settings → Domains → Add Sender Domain

   Enter the root domain (opendoors.ai, not mail.opendoors.ai).
2. 2
   Copy the DNS records

   You get three records: SPF (TXT), DKIM (2 CNAMEs), DMARC (TXT).
3. 3
   Add to your DNS

   In your registrar (Cloudflare, GoDaddy, etc.), add each record exactly.
4. 4
   Verify

   Open Doors re-checks every 5 minutes. Usually green within 15-60 minutes.
