Gmail and Yahoo sender requirements for DKIM, DMARC, SPF and reputation

Gmail and Yahoo announced in October 2023 that they would introduce new reputation requirements starting from February 2024. The new requirements apply to bulk senders only, defined as sending domains that send more than 5,000 emails to Gmail and Yahoo inboxes on average every day.

To qualify as a bulk sender an average of more than 5,000 emails to Gmail and Yahoo users need to be sent daily. The bulk sender classification is something maintained by Google and Yahoo and cannot be reverted once applied. Also there is currently no way to check if a domain name qualifies as bulk sender.

We have confirmation from some of our customers that the new rules started being enforced on the 17th March 2024 with 100% of the emails sent to Yahoo and Gmail addresses soft-bouncing if DKIM, SPF and DMARC are not set up correctly.

A few Reddit users reported seeing the new rules enforced starting in February.

In a Google Help article updated in January 2024, Google initially specified that they would not start to enforce the new rules before June 2024. The wording cannot be found now and there is no mention of postponing the enforcement of the new rules for bulk senders, the initial deadlines of February 2024 for Gmail and Q1 for Yahoo should therefore be considered valid.

The new rules for bulk senders enforced by Gmail and Yahoo

These are the 3 key compliance requirements for Gmail and Yahoo enforced right now:

- Email authentication: Senders will be required to verify their sender identities with standard protocols like SPF, DKIM, and DMARC.

- Enable one-click unsubscribe: Senders will need to implement a single-click unsubscribe link within emails if they haven’t already, to allow recipients to easily opt out.

- Only send emails users want: Gmail and Yahoo are getting serious about spam monitoring and senders will need to ensure they’re keeping below a set spam rate threshold.

The spam complaint threshold that should never be crossed is 0.30% of the total. A complaint rate of 0.10% sends a warning message which should lead marketers to check their email content, their subscription flow, make the unsubscribe option easy and clearly identifiable, and in general make sure that recipients never complain about receiving unsolicited emails.

In this article from Dmarcian the new technical and behavior requirements are made very clear and can be used to ensure compliance starting today.
