How often should I clean my email address lists?

It’s important to clean your email address lists regularly. Contacts are continuously changing jobs or positions, meaning lists can become outdated in a matter of months. Only with up to date, fully verified lists can you be sure that your emails are being delivered to your core customers. Ultimately, you should be looking to clean your email lists at least once a month, especially if you regularly send out email marketing campaigns to thousands of addresses.
