In some instances, AyaNova users have reported that if the SMTP Password: field in Global Settings uses special characters, any external email notifications fail.
If you encounter an issue sending out email notifications (as in step C of the Generator testing steps), do confirm in addition to checking your other steps, that yur SMPT Password is not using special characters. If it is, change it with your email server, edit the Global Settings and save, restart your Generator and test again to see if that resolves.
