Email authentication (SPF, DKIM, DMARC) verifies that emails claiming to be from notion.so actually come from authorized servers. Without proper authentication, emails may be marked as spam or rejected by receiving servers like Gmail, Outlook, and Yahoo.
Since February 2024, Google and Yahoo require SPF, DKIM, and DMARC for all email senders. Domains without these records see significantly higher spam rates.
