Hi there @calebellis,
Thanks for such a detailed description of the issue!
I tested the following scenario on my test site:
– I have an existing Post Notification email that is set to be sent immediately.
– I edited it to add a new text block.
– I clicked Next and then Activate.
– No new emails were sent out because there were no new posts on my site since the last time when this Post Notification email was sent.
So I couldn’t replicate the same behaviour you see, for some reason. Do you see the email that was sent falsely in the original Post Notification email history (here: https://d.pr/i/HmnNGF)? Do you see that it doesn’t have any Post content when you Preview it?
Which MailPoet version are you using? What edits are you doing to the email?
Also, can you please create a new Post Notification email with just you as a recipient, disable all other Post Notification emails, and test the same behaviour?
Lastly, you don’t have to click Activate when you need to make changes to your email. Clicking Save here is enough: https://d.pr/i/W0yKZ3.
Cheers!
