Editing Email Authentication (section)

=== Benefits of Authentication ===
There are many benefits to authenticating DKIM and DMARC:
* Reinforce your branding: You can reinforce your branding by removing the "via..." header from Gmail. A positive side effect of setting up DKIM authentication is that this header disappears.
* Build a reputation as an email sender on your domain name: Sending emails without authentication is like turning in homework without your name. You may have passed the assignment, but you can't take credit for it without your name on it. DKIM authentication, in particular, helps build your reputation as an email sender.
* Enforce stricter security on your domain name: Authentication standards such as DMARC help protect your domain name from potentially fraudulent use.

Email authentication does not solve all deliverability problems, such as whether or not the recipient wants the email. However, authentication does solve the problem of determining who the email is coming from.

A sender who follows best practices, such as sending high-quality, personalized emails to an opt-in list and performing regular list hygiene, will typically see higher deliverability when using email authentication. Their domain will build a reputation as a good sender with recipients who want to engage with their emails.

Conversely, a sender who does not follow best practices, such as using a rented or purchased list, not having clear messaging during the opt-in process about what kind of emails will be sent and at what frequency, or who never performs any list hygiene will typically see lower deliverability with email authentication. Their domain may build a reputation as a sender of unwanted emails.

Authentication allows good senders to solidify their reputation further and protect their domain from bad senders who may try to hijack their domain.
