It's great to see a new face here in the Community. Let's work together and get a better understanding of why your recurring transaction was sent in an email when you paused it until further notice.
Let's ensure that the template was paused successfully. All you need to do is check the "Next Date" column. Here's how:
Go to the Gear (Settings) icon.
Under the "Lists" section, pick Recurring Transactions.
3. Locate the template and review the "Next Date" column. Make sure it says Paused.
4. If it doesn't say paused, I recommend pressing the Edit button in the "Action" portion. From there, choose to pause the template.
If the transaction is listed as stopped, then please gather some additional screenshots of the email and the template list. This information will allow me to determine the best solution for your business.
These steps should do the trick to ensure that the transaction is paused. Let me know if this helps or if you need further assistance. I want to make sure all of your concerns are addressed. Bye for now!
