Not quite yet.I see too many tickets. did you get chance to look into this?
It's because of the resend giveups extension most likely, search the forum, @Michael Wilding came with the idea.also duplicate email sending, Today i got 4 emails from same campaign into my email box.
See if you still get duplicate emails sent to the same email addressI didn't run giveups extension on that campaign at all.
For me it seems that disabling your extension has solved the issue of duplicate sending. Not sure whether it is conflicting with something new, or just chance and is actually something else as I haven't gone through a process like @frm.mwz suggested to test it in detail.I didn't run giveups extension on that campaign at all.
