agregation data

Hello! I really need the community’s help))))
I am using a marketing pro plan.
I want to send emails to users who have renewed their subscriptions 4 times. I keep the payment dates in Deals properties.
How can I filter users by the number of payments?
F.e. if I pass the payment dates to HubSpot, can I aggregate them later?
Is there some kind of count so I can specify that payments = 4?
If I understand correctly, I need to filter by list?

Or is there any other solution within the marketing pro plan to implement such a workflow?

Hey, @ELaevskaiia :waving_hand: Can you clarify if you are looking to do this in-app, using lists and workflows, for example? Or are you looking to build an app and use our APIs to accomplish this?

Thanks! — Jaycee
