Email Authentication / Verification for Gorgias.comUpdated a year ago

When I was initially setting up my email authentication for my Gorgias helpdesk, I was a little confused that they were recommending a new MX record for my domain.

However, after taking a second look, I realized that they are essentially forcing you to set up a new subdomain to be used solely for Gorgias support emails

• My domain = smalltechstack.com
• My Gorgias email subdomain = em2244.smalltechstack.com

The required new DNS entries are as follows:

• TXT m1._domainkey.smalltechstack.com = The DKIM signature that Gorgias will apply to all outbound emails from the Help Center.
• MX em2244.smalltechstack.com = The location of the email server used for routing inbound emails from customers.  In this case, anyone emails sent to <anyone>@em2244.smalltechstack.com will be delivered to SendGrid's mail exchange (MX) servers
• TXT em2244.smalltechstack.com = The SPF record to be used for the email subdomain em2244.  Since Gorgias is the ONLY service that will be sending emails on behalf of this subdomain, the only entry is that of their email service provider (ESP) SendGrid.

Note: The one piece of information NOT provided in this process was the MX Priority number.  Since there is only one MX record in this case, it actually doesn't matter what you put here as long as it is a number that is valid for MX priority.  This means it needs to be between 0 and 65535 (inclusive).  I chose a value of '10'.
