Hi Ryan,
You can use the email module with tempalates module. When testing projects I use a gmail address to send emails.
Here is a link to the module
https://appstore.home.mendix.com/link/app/259/Mendix/E-mail-module-with-templates
a link to some instructions to get you started implementing the module
https://forum.mendix.com/link/questions/89106
and a link to some information about gmail smtp settings
https://www.wpsitecare.com/gmail-smtp-settings/
sometimes when you use a gmail address you are blocked by security. If you log into that email address through a browser you will get an email from security and can grant access to your application. I think there is also another security setting to prevent this too.
Hope this helps!
