This setup guide provides step-by-step instructions on integrating SMTP2GO and Sage 100.

We have created an excellent migration guide to help you move to SMTP2GO from your existing provider.

Please also note that your sending domain needs to be verified in the Verified Senders section of your SMTP2GO dashboard. Ensuring your domain is verified will give SMTP2GO full permission to send email on your behalf, allow full digital signing of your email, and help make inbox placement a breeze.

Step 1


  • Library Master,
  • Main menu, then
  • Company Maintenance

Click the E-mail tab.

Step 2

In Address enter: mail.smtp2go.com

For port, try 25, 2525, or 587.

Choose START TLS from the SMTP Encryption drop down box.

User ID is your SMTP2GO Username. This can be found in the “Settings > SMTP Users” section of your SMTP2GO dashboard.

Domain is optional, but would be your sending domain name should you choose to enter it.

Password can also be found in the “Settings > SMTP” section of your SMTP2GO dashboard.

Step 3

Use the “Test E-Mail…” button to check the settings are working. If you encounter an error, re-check your username and password, or try a different port number.

Click the “Accept” button to save the changes.

Integrating SMTP2GO and Sage 100 should be an easy, quick and, hopefully, painless process. And going forward your email delivery should be outstanding.

You can access reports directly in your SMTP2GO dashboard, which will help you understand delivery successes and failures, tracking information and many more useful metrics. We’ve written some great articles outlining the features of your SMTP2GO account and we recommend taking the time to see everything we have to offer.

Should you need extra help from our award winning support team, we are almost always available to assist. You can find support contact details in your SMTP2GO dashboard and information about retrieving your support PIN here.
