I would like to Automatically add subscriber to an email group based on the service that he buys.
Client Jonh Doe buys Service_X and he automatically enter the email group for Service_X.
I need this thing, or similar, feature because in this way I can contact all the clients that bought a particular service with one email sent with a Newsletter.
p.s. if there is a simpler way to achieve this let me know, I’m new to erpNext. Thank you so much!
