Pre-Dunning emails are where you send an email to a customer before their card is expiring asking them to update it.
It used to be key, as like the current day when a card expires services can experience interruptions.
Stripe Card Auto Updater
However today, ( I say today but Stripe introduced this in 2015) use a process called card updater, it communities with card providers like Visa and Mastercard and updates expired cards automatically. Last time I researched it 70% of cards were getting automatically updated.
With this high rate of success with cards automatically updating the process of sending a Pre-Dunning email can have a negative effect on your customers. It’s more emails your sending them which 7/10 times was not needed.
If you do want to remind customers it’s far better to send it with a message that offers real value and added it as a point.
