The Importance of Email Authentication

Email authentication is a way to ensure that an email provider will be able to recognize the sender of an incoming message, encouraging delivery rates and reducing spam reports.

Two reasons why email authentication is important:

  1. Security
  2. Deliverability

An example of this is an email message that is claiming to be from your personal bank, usually stating there has been unusual activity and requires your immediate attention when it’s actually a scam aimed at stealing your money or spreading malicious software.


It is important for a business to utilize this feature when sending email campaigns to their users. If your company is the victim of email hacking, then most likely your users will no longer trust you, resulting in an unhappy experience, high unsubscribe rate and the potential to damage your online reputation.
