Klaviyo deliverability checklist

0/8

The thresholds used here are the ones an account manager watches day to day, and the ones KlaviBoard applies continuously: bounce rate above 2%, spam complaints above 0.1%, unsubscribes above 0.5%, bot clicks above 25% of all clicks. For the detail and the reasoning behind each one, read bounce, spam, bots: the thresholds that should alert you. For the wider numbers, see the key email marketing statistics.

This tool looks at one account at a time, by hand. KlaviBoard makes the same reading continuously across every client account and raises an alert when a threshold is crossed, without anything to plug in.

Watch deliverability across every account

KlaviBoard applies these thresholds continuously across 3 to 20 Klaviyo accounts and warns you when one slips. The Free plan connects 3 accounts, no credit card.
