This article covers the SPF and DKIM authentication processes for SMTP2GO and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Sender Domains

For maximum email delivery rates and better branding, we recommend adding any domain names (that you send emails from) to the "Sending -> Verified Senders -> Sender domains" section. Adding a verified sender domain means that SPF and DKIM are automatically handled by us, and use DNS records at your own domain name.

To set up a verified sender domain, follow the steps below:

Step 1

From the left-hand menu, make your way to the Sending -> Verified Senders -> Sender domains page in your SMTP2GO control panel.

In the Sender domains section, click Add sender domain, enter your domain in the textbox and click Continue with this domain. For example, if you send your emails from [email protected] then you would enter

Step 2

Publish the DKIM key on your domain's Configuration page in Valimail.

As long as your domain is showing as Verified on your Verified Senders page, it is setup and working correctly.

Step 3

To set your tracking domain (for any links in your email) to use secure "https" instead of "http", click the Enable hosted SSL checkbox and click Verify. If the previous three steps have been completed and verified, you won't need to do anything else.
