Hi Callum,
Great plugin, thanks.
Today I noticed an e-mail that was supposed to be send, hadn’t happened. Other mails are getting through fine.
I’m using your plugin in combination with Gmail. My best guess is that the server just couldn’t connect to Gmail for a short moment. Thus the mail disappeared into nothing.
It would certainly be nice to receive a notification whenever this occurs! Is that possible, or would you consider adding such a feature?
Thanks again!
