If you use Mailtrack with an email address that has a domain configured with its own SMTP then verifying the domain with us can help make sure your emails land in inbox as much as possible.
To verify your domain:
1) Go to the Account section of your Mailtrack dashboard.
2) Click Manage domains.
3) If it's the first time you've verified a domain with Mailtrack you'll need to generate a private key.
4) This will then give you the name of the TXT record and the value you need to add to your domain's DNS.
Once you've added the TXT record to your domain's DNS it can take 1-2 days for the changes to fully propagate. Usually, though, the changes are reflected before then.
