Keep your email lists clean Keeping invalid email addresses, as well as inactive or disengaged users, on your list can harm your delivery rates and, ultimately, your sender reputation. Ideally, you only want to be marketing to people who are actively interested in receiving your messages. List hygiene should be near the top of your list of marketing priorities; you should aim to clean your B2B lead lists a couple of times per year at least. You can spot when it’s time to take action when your marketing campaign analytics reveal a large drop in your open and click-through rates. Unsubscription, bounce and spam complaint rates are an indicator too. Turn this around with an email cleaning service like EmailChecker, which offers both bulk list cleaning and real-time verification with domain, mailbox, syntax and format checks.
