Tried to follow directions with simple instructions and view a few YouTube email. Set up simple Inject Node with a text payload. When activated the email node shows send failed. Have outgoing email in place and using a known gmail account as sender. Any other ideas.
Use a Catch node to catch the error in the email node and see what it says.
Debug shows this: Error: Invalid login: 535-5.7.8 Username and Password not accepted. Learn more at

Checked my log in and password. Both are correct.
I believe that @jbudd has pointed you to a possible solution.
For Gmail you need to generate app password and use that instead of gmail password. Refer below link.
