Email list cleaning service is a tool that helps keep your email lists clean by removing low-quality subscribers. You upload your email list, and the tool analyzes each address to determine which are safe to send to, which should be removed, and which have a history of deliverability issues or spam complaints. The best list cleaning services also have tools that can verify new emails in real time, ensuring that the addresses you’re importing from your website or using on signup forms are valid and will be able to receive your newsletters.

A clean, well-maintained email list can have a huge impact on your overall email marketing performance. By removing unengaged, invalid, and inactive subscribers you’ll increase your deliverability, open rates, click-through rates, and conversions. Keeping your email lists squeaky clean is just as important as maintaining your website or growing your subscriber base, and should be a part of your regular workflow.
