  1. First, you’ll need to sign up for a Postal account. You can do this by visiting the Postal website and clicking the “Sign Up” button.
  2. Once you’ve signed up for an account, you’ll need to select a plan. The plans start at $5/month for 500 monthly emails. If you need to send more than 500 emails per month, you can choose a higher-priced plan.
  3. After you’ve selected a plan, you’ll be taken to the Postal Dashboard. From here, click on the “Servers” tab and then click on the “Add Server” button.
  4. Enter your server name, IP address, and port number into the fields provided. The default port number for SMTP is 2525, but you can use a different port if necessary.

  6. Now that your server is set up, you’ll need to add your Domain Name System (DNS) records in order to complete the process. To do this, log into your DNS provider.

Testing your new SMTP server

  2. Enter your email address in the “From” field, enter the recipient’s email address in the “To” field, and then type out a brief message in the “Message” field. Once you’re done, click the “Send Message” button.
  3. If everything is working correctly, you should receive an email at the other end within a few minutes. If you don’t receive anything, or if you get an error message, then something is wrong with your server and you’ll need to troubleshoot it before you can use it for real-world purposes.
