Our Email system uses SMTP (Simple Mail Transfer Protocol). This allows you to connect to any email system you have that supports SMTP, and most do.
You can usually find out your SMTP setting from your Email provider. If you're using Email from a web email service like Google (Gmail) or Yahoo, you can look it up on the internet.
The settings you'll get from your Email provider are at the top. You'll need to know what port, and if they use SSL and/or Email Authentication.
The Default settings are where the Email comes from, and where it goes when you're sending bulk (many emails at once).
The best thing to do is try it out.
When you think you've got it setup, click on Set Mail Server first, then click on Send Test Email. If it's going to error out, it may take a few minutes to get the error back, so be patient, do not shut down the program. You will get a Successfully sent message pretty quick if it works, and you'll get an email in your inbox.
