Hello @Saurabh-704
Sounds like you want to have a Recurrent flow that runs every day and gets all Lead entities, which are active? and which has a Remainder (Reminder?) date set and the date is equal to today + X days.
The flow then loops (Apply to each) through each Lead entity and sends out a reminder.
The above will tell me to use the following triggers and actions:
Recurrence trigger set to run every day at 08:00 local time.
Get Lead entities with Filter Query set to include only active entities and Reminder ne null and Reminder date eq "formatDateTime(addDays(utcNow(), X),'yyyy-MM-dd')' (< is an expression in single quotes)!
Apply to each on the output from Get Lead entities
Send email inside the Apply to each with information about the Lead entity
Hope this helps, Kind regards, John
