Maintaining a clean email list is essential for improving deliverability, protecting sender reputation, and driving engagement. Over time, email lists accumulate invalid addresses, leading to higher bounce rates and lower performance.
Prismfly’s List Hygiene tool ensures your email campaigns reach the right audience by validating and cleaning your Klaviyo profiles.
A thorough clean-up of your email list involves identifying and removing invalid, spammy, or risky emails to set a strong foundation for future campaigns.
Continuous monitoring and cleaning of new email addresses ensures proactive management and seamless integration into your Klaviyo workflows for an optimized list.
Automated addresses used by scripts or systems, not real users.
Fake or abandoned emails used by providers to flag poor list hygiene, severely impacting sender reputation.
Emails with domains known for spam or fraudulent activity.
Temporary addresses used for one-time purposes (e.g., capturing signup discount codes).
Email addresses unable to receive messages due to storage limits
Domains without valid mail server configurations
Addresses frequently reporting emails as spam
Emails flagged as un-engageable or restricted from sending
Addresses likely to result in permanent delivery failures
Addresses tied to spam complaints or malicious use

Addresses pointing to non-existent mailboxes
