SMTP2GO is an email deliverability solution. You can use the ESP (Email Service Provider) to send your transactional and marketing emails and view reports on email delivery. But before sending any email let’s authenticate your domain by configuring SPF and DKIM records.
Your first step is to add your sender domain. To add your sender domain please follow the steps below and meanwhile have a look at the screenshot.
1 – click on the Settings from the left side of the dashboard.
2 – Click on Verified Senders from the drop-down menu.
3 – From the Verified Senders page click on the Add sender domain button.
Once your domain is added you will be provided with three CNAME records to publish in your DNS host.
The first CNAME record in the above screenshot is for SPF.
Note: There is no need to update your current SPF record and add an include for SMTP2GO, as adding that CNAME record already maps your domain to another domain (return.smtp2go.net) that has the IP addresses whitelisted in it. Which allows you to have authentication and alignment for SPF without having to manage your SPF record manually.
And the second CNAME record in the above screenshot is for DKIM. In this article we’ll show you the configurations only for SPF and DKIM without referring to the third CNAME record that is used for click/open tracking and unsubscribe links. Now let’s move on with publishing the CNAME records in your DNS zone.
Copy and paste the CNAME Records for SPF and DKIM in your DNS host.
