How important are clean email lists?

Very important! Clean email lists ensure that your email marketing strategy doesn’t go to waste. If you send your next campaign out to unverified and outdated emails, you’ll find that you have a very low conversion rate as well as unreliable data. With a clean list, however, you’ll only be sending your email out to fully verified addresses, allowing you to communicate directly with your core customers and shape your email marketing efforts around them.
