Hi BenTSA,
Totally get where you're coming from. If you've got thousands of customers paying each month, those emails would drive anyone a bit mad. Thanks for calling out. There isn't actually an option to fully switch those payment notification emails off (I know, not ideal). The best workaround for now is to remove the email address that's set in the Reply To field. That usually stops the inbox from getting hammered every time a payment comes through. You can do that by going to Setup > Preferences > Emailing. Then just clear out the email address in the Reply To section and hit OK. It's not a perfect fix, but it should at least keep things quieter on the email front.
Regards,
Sai
