Frequently asked questions

What are Google’s email sender requirements?

Bulk senders need SPF and DKIM, a DMARC record (min p=none), From alignment, PTR/TLS, one-click unsubscribe for marketing, and a low complaint rate. This page checks what DNS can show.

Are Yahoo’s rules the same as Gmail’s?

Largely yes: SPF+DKIM, DMARC, unsubscribe and complaint thresholds. Both appear on the Google/Yahoo card.

What did Microsoft require in 2025?

High-volume senders to Outlook.com/Hotmail/Live need SPF, DKIM and DMARC (≥p=none) with alignment. Non-compliant mail may go to Junk, then reject.

Is p=none enough?

Yes as the published minimum. Move to quarantine/reject for protection; BIMI usually needs enforce.

Is this inbox placement?

No. DNS identity only — no seed inboxes or folder measurement.

Prefix?

Type compliance:example.com or gmail-yahoo:example.com in the super box.
