Gmail and Yahoo require bulk senders (roughly 5,000+/day) to: authenticate with SPF and DKIM, publish DMARC (at least p=none, aligned), support one-click unsubscribe (RFC 8058), and keep the spam complaint rate under 0.3%. Enforcement (p=quarantine/reject) is the recommended end state.
1) SPF and DKIM on your sending domain. 2) A DMARC record with alignment (start at p=none, progress to enforcement). 3) One-click list-unsubscribe for marketing mail. 4) Spam complaint rate kept below 0.3% (ideally under 0.1%). 5) Valid forward and reverse DNS (PTR) and TLS for connections.
Authenticate every sender, publish DMARC, and monitor reports to confirm alignment before enforcing. Automation gets you compliant and enforced fast without risking deliverability.
| Requirement | Needed for bulk senders | Notes |
|---|---|---|
| SPF + DKIM | Yes | Both, aligned to From |
| DMARC record | Yes | p=none minimum; enforce recommended |
| One-click unsubscribe | Yes | RFC 8058, marketing mail |
| Spam rate < 0.3% | Yes | Keep under 0.1% ideally |

It meets the minimum DMARC requirement, but enforcement (quarantine/reject) is recommended and protects you from spoofing.
