I’m using manager 15.0.10 but my emails are unable to be sent. I am using the no-reply@manager.io in the from field. Tracking is enabled and smtp disabled.
The message I keep getting is An exception occurred during a WebClient request.
Then I can’t help you, other than to suggest searching the forum. There have been many threads on that issue. Perhaps one will help, but perhaps not. Personally, I don’t send emails from Manager, so I have experience with it.
