Cohort retention코호트 리텐션

See how many customers acquired together remain active over time.

Quiet hours prevent non-urgent messages during a defined night window in the recipient's local time. The same scheduled instant can yield a different result for customers in different time zones.

Move the demo clock and a message is held from 22:00 until 08:00, then becomes eligible again. The clock auto-plays before manual input.

Localizing the schedule is insufficient if the quiet-hours check is missing. Define what happens when the customer's time zone is unknown or wrong.

When to use

Use it when scheduling non-urgent messages across customer time zones.
