Learn about email deliverability anomaly detection in Klaviyo, and how you are notified if an anomaly is detected.

Deliverability anomaly detection

Deliverability anomaly detection in Klaviyo alerts you when a dip in your email deliverability is detected. This will help you quickly identify and resolve any sending issues. Klaviyo will notify you in cases where your campaigns are experiencing elevated bounce rates due to a sender reputation or spam content problem. You will receive the alerts in:

• The account owner’s email inbox
• An in-app notification on your Klaviyo account home page
• An in-app notification on the campaigns list-view page in Klaviyo

Why emails bounce

A "bounce" occurs when an email is either not successfully delivered or is rejected by the recipient's inbox provider. If your account has a high number of bounces, this can have a negative impact on your deliverability rate. There are 2 types of bounces:

• A soft bounce is always caused by a temporary reason, such as when a recipient's inbox is full or when their email server is momentarily down. If an email soft bounces more than 7 consecutive times, Klaviyo will suppress this address.
• A hard bounce occurs when an email cannot be delivered due to a permanent reason. This could be caused by a variety of reasons, including a misspelled email. Klaviyo automatically suppresses any email address that hard bounces.

Outcome

Deliverability anomaly notifications can help you identify when and which inbox providers are seeing a sudden dip in delivery rate, and provide you with next steps to repair your reputation.
