How do I clean bounces from my list? Does Klaviyo do this automatically for me?
Yes, Klaviyo automatically cleans bounces from your list through suppressing those contacts. If an email in your account hard bounces one time, they will be suppressed. If they soft bounce 7 times consecutively with no successful deliveries in between, the customer email is automatically suppressed.
If you would like to clean bounces prior to reaching 7 consecutive soft bounces, you can create a segment of your customers who have bounced a certain number of times (i.e. 3x) and suppress that segment of customers.
