Gmail/Yahoo bulk sender requirements — one‑pager
This page distills the must‑have items: SPF/DKIM, DMARC policy, alignment, and one‑click unsubscribe. Use the inline audit to verify each item and generate verifiable evidence.
Quick check
Checklist
- SPF present and single, lookups ≤ 10
- DKIM present; at least one selector passes
- DMARC policy: quarantine → reject; alignment as required
- List-Unsubscribe and One‑Click supported
Am I affected?
Bulk senders (regular marketing/transactional volume) should comply. If you use multiple ESPs or route via vendor domains, alignment is easier via DKIM while SPF remains relaxed.
Alignment details
Relaxed alignment compares organizational domains (PSL aware). Strict requires exact match. Start relaxed, tighten strict on stable routes with strong DKIM.
