Bulk Sender Requirements in 2024 — Google, Yahoo, and What's Coming
2024 shifted “nice to have” to “blocked if missing” for high-volume senders: authenticate your domain, keep spam low, make unsub easy. The details moved twice — treat vendor blogs as source of truth.
Your stack: deliverability guide, List-Unsubscribe (glossary), DMARC aggregate monitoring.
FAQ
Is p=none enough for DMARC?
For many bulk requirements — yes — but you must publish a record and align mail.
List-Unsubscribe?
One-click headers required for bulk — RFC 8058 style.
Spam rate threshold?
Keep spam complaints low — check Postmaster and internal metrics.
Applies to small senders?
Volume thresholds — transactional-only may differ — read current provider docs.
What about February 2024?
That was the major deadline — requirements evolve — monitor Postmaster + Yahoo sender hub.
