Gmail and Yahoo announced updates to its sender authentication policies, effective February 1, 2024. These changes aim to reduce spam by requiring bulk senders to authenticate emails, support easy unsubscription, and maintain a spam complaint rate under 0.3%. Bulk senders are defined as those sending to 5,000 or more Gmail recipients per day. The updates include the use of SPF, DKIM, and DMARC email authentication. Additionally, Google advises supporting one-click unsubscribes through specific message headers. Failure to comply with these requirements may lead to emails being marked as spam or not delivered as expected.
Mailster provides an effortless approach to assessing the well-being of your emails, giving you an expedient snapshot of your delivery configuration.

There are several ways to access the Email Health Check:
- Find the link on the “My Mailster” dashboard metabox
- Go to the delivery tab in the settings and click on “Email Health Check” below the send test option
- Enter the URL manually
Run the Email Heath Check
Once you reach the page you can start the test with a click of a button.
The test will check your, SPF, DKIM, and DMARC settings as well as your reverse DNS, MX, and A records and finally if your sending IP is listed on a block list.
The functionality is based on the precheck service.
