Email authentication is like a ‘must-to-do’ thing for business especially where bulk messages are transfer in a minute.
However, there are various ways and methods to send e-messages that can be anywhere from web portal, to web-based application, mobile apps to PWAs, etc.
Thus, authenticating emails can be tricky! Here are five simple and easy to understand steps for email authentication.
Step 1 – Authenticate using SPF and DKIM can be easy and effective ways. This new technique utilizes ISPs to identify and treat email that is not properly authenticated.
Step 2 – Create a roadmap of all the IP addresses that you may wish to send email. Further, authenticate all of your mailstreams or risk being blocked by ISPs at the gateway.
Step 3 – Create your authentication record on SPF and DKIM, then publish them. To do so, visit each of their websites for details.
Step 4 – Setup your mail server to sign outbound email with DKIM. It’s also the easiest way.
Step 5 – At last, you can test your records using DKIM tools ‘Policy Record Test’ and ‘Selector Record Tester’ and SPF has a series of tools. You can try anyone from both.
