Email Domain Authentication: How To Authenticate Email Sender Domain?

Last Updated: Jul 13 2018 01:50 pm UTC

Email authentication is needed to verify the identity of the email sender in order to confirm that the sent email comes from the right source - the one which is listed as the sender.

“From Company X [info=deliverability.com@mlgnsrv.com] on behalf of Company X [info@deliverability.com]”.

When you use our platform to send an email campaign and your own email address has been validated, your recipients will receive your email address shown in the “From” line, not our server domain. The result is the following line:

"From: Company X [info@deliverablity.com]".

You can set up domain authentication in your account, in the section "Email Authentication".

Next, you will need to enter the domain for authentication.

Note: To authenticate your domain correctly you must enter only the name of your domain.

Correct: example.com

Wrong: www.example.com

After entering the domain, a page with three entries will appear - DKIM, SPF and DNS verification.

To successfully complete the authentication, you need to add all these entries to the domain zone. If there is a person in charge of editing the site or receiving mail, transfer the record data to add to it.

Note: If DKIM records in the domain zone can be any number, then the SPF record should always be only one. If there is already one SPF record, then you need to combine them.

After adding records to the domain zone, go back to the page where you received the entries, and click the "Verify Records" button. If everything is correct, the status of the records will change to "Record is confirmed".

Authentication was successful if SPF, DKIM, Sender ID and Verification were marked "Verified

The next time you send messages from this domain, the "Authenticate campaign" option will be available during the configuration of the sender at the first step of creating the campaign.

You need to authenticate your email in order to authorize/approve the campaign to be sent from your email address with our server entries, which will be later identified by the receivers in Gmail, AOL, Hotmail, Yahoo and MSN.

All major Internet and email service providers (later- ISP) use email authentication data to protect themselves against spam.
