i, I have been sending emails in Unity for the last 5 days without any issues. The emails were successfully delivered to users, but suddenly I started encountering an error: ‘Failed to send email: 535 Authentication failed’. Could you please assist me with resolving this issue?
Uh… Unity?
If this is a Ghost question, please provide a lot more detail about your hosting and email setup.
If this is a Unity question, I’m not sure why you’re asking it here…
