On October 3, 2023, Google announced new restrictions to combat unsolicited email marketing. A big change to email marketing laws is on the horizon, set to take effect on February 1, 2024.
The changes require bulk senders to authenticate emails, include easy unsubscription links, and stay under a reported spam threshold that could see domains blocked if they exceed them. These restrictions apply to parties sending over 5,000 email messages to a Gmail account in one day. Bulk senders must include a one-click unsubscribe button and authenticate their domains using correct DKIM, SPF and DMARC records.
