How important is it to have clean email lists?

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 If you send out your next campaign to unverified and outdated email addresses, you’ll find that you’ll have a very low conversion rate, as well as unreliable data.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