How to schedule an email before 1 week of client's renewal date?

Hi @Prodsquads, welcome to the community!

Is the renewal date stored in each customers’ profile?

Assuming you have the renewal date stored as a custom property in their Profile, you can use a “Date Triggered Flow” to automatically send an email 1 week before the renewal date. 

You can see this documentation for more information:

• How to create a date property-triggered flow

Let me know if that helps, or if you have any further follow-up questions

I have some client’s data. I provide them services and this service needs renewal. Its more likely subscription. Some clients take 2 month, 4 month, 6 month, 1 year, 2 year of subscriptions (depends on their need). Now What i want is, I simply want to send them the reminder before 1 month of their service renewal date. 

Please provide a stepwise and working solution. 

Many thanks
