How to write a test case that requires TestComplete to access and retrieve text from an e-mail

I am currently working on a keyword test that needs to provide a verification code from an e-mail address in order to login to my site. I originally had this test case set up to navigate to google gmail and read the e-mail, but it no longer appears to be working. I suspect there is a better approach to dealing with this scenario since it relies heavily on a 3rd party (Google). I am open to using a different e-mail (ie. Microsoft Outlook), but I would like to know if there is a best practice for handling these situations where MFA verification codes are required to login/verify e-mail.
