There was a problem sending the test email. Double check your settings. #3
Description
I know my creds are correct. I don't have the SSL setting checked and I'm sending with REST.
I keep getting the error: There was a problem sending the test email. Double check your settings.
which isn't very helpful.
What else do I have to do to send a test email?
Using on multisite (as network settings)
