Microsoft canceled its planned External Recipient Rate limit of 2,000 per day for Exchange Online bulk senders due to customer feedback, keeping existing limits (10,000 recipient rate and 5,000 external recipients per tenant per day) unchanged. The report also notes Google’s continued tightening of bulk sender rules, requiring SPF/DKIM/DMARC, higher spam thresholds, one-click unsubscribe, and quick processing of unsubscribe requests.
