Upcoming charge notifications are sent daily between 7 PM ET and 11 PM ET. By default, the upcoming charge notification is sent three days ahead of the queued charge date. The time of day notifications are sent cannot be adjusted. 

Click Email, under Notifications select Customer, and choose Subscription upcoming charge to adjust the number of days before the charge notification should be sent.

You must contact the Recharge support team to update your notification settings for prepaid order shipment notifications. 

Klaviyo and Recharge

Note that Recharge sends the upcoming charge events to Klaviyo between 1 PM and 4 PM ET. After Recharge sends the upcoming charge events to Klaviyo, Klaviyo handles the notifications you have tied to these event metrics, which may result in timing variations compared to Recharge's in-house notifications.
