Q: I tried connecting to Gmail to email a PDF from PDF Studio and got the following error message:

530 5.7.0 Must issue a STARTTLS command first. n45sm1978507yho.32-gsmtp

A: Make sure to check the box for “StartTLS” under the Internet Email Settings.

You can access Internet Email Settings under Edit > Preferences > Mail.
