Hey there @rokinisgritinis - I found this thread that has a relatively similar question:
What I may suggest you read up on, as mentioned in that thread would be a filter step, which would allow you to dial in more specifically on when you wanted to send the email: https://help.zapier.com/hc/en-us/articles/8496276332557
To be completely honest I haven’t used Stripe so I’m not 100% what data is shown in your Zap, if you give it a try and then sent a printscreen over (with any personal info removed!) we can help troubleshoot from there as well.
Hope this helps get things in the right direction!
