A practical setup guide for getting outbound email healthy before you start sending real client messages.
The most common email problem is trying to send before the domain is verified. If the sender is not trusted, delivery will be unreliable or blocked entirely.
Verifying your domain first gives you a better chance of landing in the inbox and makes your business look more legitimate to clients.
Create your sender account, add your domain, and copy the DNS records exactly as provided. These usually include SPF or DKIM-related records depending on the provider flow.
Add the records at your DNS host, wait for propagation, and only then run the test send inside Customerscor.
If verification does not complete, double-check that the record names and values match exactly. A single missing character or a duplicated domain suffix is enough to break it.
If sending still fails after verification, confirm the from address uses that exact verified domain and not a personal mailbox on another provider.
