Hello,
Sorry to hear that!
The same email went 3 times or 3 identical copies of one email went once? We know there was a punctual bug that could potentially create one or two copy of the same email, in some very specific case but it has been secured since then.
Make sure you have the latest version always.
If you still have similar issue with the latest version please make sure you contact us on our support site : support.wysija.com
Thanks,
And sorry again for the inconvenience.
Ben
