For some reason I had 1100 emails go out in one hour. I shut it down in a few days later I tried it again and 100 emails went out in just a few minutes.
I just looked at mail jet for the last 7 days. It's showing 3 to 4000 a day starting on the 7th. that's way to much for my site.
Me too, I am using mailjet too and had to disable it because the cost went sky high. That’s how I noticed what was happening.
