Adding a domain
To add a domain, go to “Profile”, then “Preferences”, and access the “Domains and DNS zone” section.
Once there, click “Add”, enter the domain you want to configure, then confirm to start authentication.
After adding the domain, copy the host and value information provided to you.
Setting up the DNS entry
Next, log in to your web hosting provider's site and add a TXT entry in the DNS configuration for the relevant domain using these values.
Save the change to verify the domain. DNS propagation can take anywhere from a few minutes to 24 hours depending on your hosting provider.
Adding a sender
Once your domain is verified, you can add the sending addresses you'll be able to use for your email campaigns.
To do this, click “Add a sender” and fill in the requested information.
Once confirmed, the address will be available for sending your campaigns.
