Send Configuration

Send Configuration Overview

Choosing a sender email for your newsletter is an important step. Your sender email should allow your contacts to recognize you easily and makes your recipients feel confident about opening your newsletter. Add Sending Domains, Sender emails, and Reply-To emails under -> Settings -> Send Configuration.

  • Your Email Domain is the part of your email address that comes after the @ symbol. Choose a sending domain you want to use and authorize it by adding new DNS records (DKIM, SPF, DMARC authentication) on your name server. It may take up to 48 hours for these changes to propagate worldwide. If you don't have a domain, you can contact us to use one of MailExpress's subdomains to send your campaign emails. 
  • A Sender Email is always your business email address, it reflects the “From” part of your email, you can only select the email addresses from the authenticated/active domains. You can add up to 10 sender emails.
  • A Reply-To Address is added when you want the replies from your subscribers to go to a different email other than your sender email.

Add Sending Domains

Click on the "Add Domain" button to add a sending domain, the domain name should not contain http://, https://, www.

View your domains and their status under -> Settings -> Send Configuration

After the DNS is verified, the domain will show "under approval" status, then we will manually review and finish the final IP set up in the backend. After that, we will change the status to "active", and the user will get an approval notification email. It will take about another 24-48 hours.


Domain Status 

  • Active: domain is ready to use 
  • Under Approval: DNS verified, we are doing a final review and IP set up. It may take up to 48 hours for you to get an approval email

Click on -> Authenticate Domain or the Domain Name to view more DNS settings. To complete the authentication process, simply copy the TXT(DKIM), TXT(SPF), MX, TXT(DMARC optional) texts, and add new DNS records to your domain’s name server. Here are some instructions for editing DNS records with popular domain providers.


Once added, click on -> Verify Status to start verifying. It takes around 24-48 hours for it to propagate worldwide.
