Hey, just wanted to share this simple trick. It allows you to check if SPF, DKIM and DMARC are working correctly. All you need is a Gmail account.
These are the steps:
- Send the Email or Newsletter for Testing to Your Gmail Address.
- Open the Email and Click the Three Dots
- Select “Show Original” to View the Source Code
- Analyze the Authentication Results (it has to say PASS for all three)
Hope this helps!
