Hi, I have been trying to build a PowerAutomate flow that will send personalized email reminders 14 days before a deposit payment is due to about 300 customers. Each customer has multiple payments different due dates that stretch for the next 4 years or so.
I have an Excel spreadsheet, (I can also use a SharePoint) list with rows for for customer name, email, deposit amount due, and the applicable deposit dates in columns. (See below example).
The challenge I have is with a schedule flow, I only seem able to send a reminder based on a specific date, meaning I would require a "reminder date"column for each payment date on the list. As the dates are all over the place, I would need add a lot of extra columns.
Does anyone have a solution where I send and email to each customer prior to their specific due date, inserting their name, (and hopefully due date and amount due), in the body of the email?

Thansk
