Microsoft is combating spam by implementing a daily Exchange Online bulk email limit of 2,000 external recipients from January 2025. This aims to prevent resource abuse and unfair usage. The limit will be phased in and existing tenants may need to switch to Azure Communication Services for Email. Google has also tightened spam thresholds and authentication guidelines for bulk email senders.
From the meeting notes, the key takeaways are:
– Microsoft is implementing a daily Exchange Online bulk email limit of 2,000 external recipients starting January 2025 to prevent abuse of resources and unfair usage.
– This limit will be introduced in two phases, with the first phase applying to newly created tenants starting January 1st, 2025, and the second phase applying to existing tenants between July and December 2025.
– Exchange Online customers needing to exceed the ERR limit will have the option to switch to Azure Communication Services for Email, designed for business-to-consumer communication via high-volume email to external recipients.
– Google has also implemented stricter spam thresholds and authentication guidelines for bulk email senders, including requirements for SPF/DKIM and DMARC email authentication for domains sending over 5,000 messages daily to Gmail accounts. Additionally, bulk email senders must avoid sending unwanted or unsolicited messages and provide one-click unsubscribe options, with failure to comply resulting in Gmail rejecting offending emails.
