I ended up disabling the summaries altogether. I did receive a response back to the contact form I submitted- it was recommended to install another plugin to control it, but I try to keep our plugins to a minimum.
I do want to take the opportunity to say- very disappointed in the customer service received in this experience. The email I received back from my contact form was more concerned with confirming my payment information than helping the issue or getting to the root of it. I’m a Lite user, so I’m directed to this forum for support inquiries. Had I waited for a response, I’d legitimately have tens of thousands of summaries in my email by now, on top of an above-average Postmark bill. Seriously, the volume I received in a single afternoon was nothing short of insane.
@dan1980 I disabled summaries under the “Misc” tab in plugin settings if you’re inclined to do the same
