## Description

Klean13 is an email list hygiene software brand operated by Send13, LLC. Its service helps email marketers clean existing contact lists by identifying and removing problematic or low-quality addresses before they are imported into an email service provider. The platform is designed to detect issues such as dormant accounts, spam traps, invalid addresses, misspelled domains, role-based accounts, serial complainers, and bots. Users upload a list through a drag-and-drop interface, let the software clean, verify, and validate the data, then download the processed list for use in their email campaigns.

Klean13 positions list cleaning as a way to support more consistent email delivery, stronger inbox placement, higher engagement, improved sender reputation, and better conversion rates. The company says its service can help marketers maintain their standing with email service providers and make their lists more valuable by removing bad data. Klean13 offers plans and pricing for its list-cleaning service, alongside customer case studies, testimonials, and support information.
