Who this applies to#
- Yahoo separates requirements for all senders from requirements for bulk senders
What Yahoo sender requirements requires#
- Yahoo bulk senders need SPF and DKIM, aligned DMARC at least p=none, easy unsubscribe, valid DNS, RFC-compliant mail, and spam below 0.3%
What this does not require#
- Yahoo accepts mailto for unsubscribe and does not establish a numeric bulk threshold in the captured source
Common mistakes#
- Inventing a numeric Yahoo threshold
- Copying Gmail's POST-only interpretation onto Yahoo
Yahoo sender requirements checklist#
- Separate all-sender and bulk rules
- Provide unsubscribe paths
- Keep provider scope explicit
Commonly confused with#
OnVoard's take#
Yahoo guidance is useful precisely when its provider-specific scope and non-numeric bulk definition remain visible.
