Any fix for this yet. I am getting as many as four copies per email.. I have done some testing and disabled a couple of other plugins such as SB Better Emails and Welcome email editor but it was still sending multiple emails. Someone suggested switching to Postman SMTP and well this seems to have fixed the issue but I would rather keep things as they are an continue to use the wp smtp mail plugin but I can't have it sending multiple emails.
Any luck with this yet?
