Connecting your email sending domain adds another layer of authentication to your HubSpot emails by providing HubSpot the permission to send emails on your behalf.
This helps prevent your marketing emails from being caught in spam filters and removes the ‘via HubSpot’ text in the sender information of these emails.
The exact steps to connect your email sending domain can be found here.
That said, a common issue with GoDaddy is that it will automatically add the domain at the end of the record. For example, we would be trying to input these two values to update the CNAME records:
hs1-123456._domainkey.example.com
hs2-123456._domainkey.example.com
records to update
But specifically for GoDaddy, an additional domain will be added, resulting in the final updated records propagating as:
hs1-123456._domainkey.example.com.example.com
hs2-123456._domainkey.example.com.example.com
As such, HubSpot would not be able to validate the updated records resulting in a ‘record invalid’ alert. This prevents the email sending domain from connecting to HubSpot. Here's a handy guide on how you can verify if this is happening.
To prevent this from happening, we can input the updated values without the domain - as an example:
hs1-123456._domainkey
hs2-123456._domainkey
This should allow you to connect your email sending domain to GoDaddy - hope this helps!
