The digital marketing business has changed dramatically since we posted our Top 5 Email List Companies back in 2022. AI dominates the market now and every marketing company out there is selling some kind of AI tool or program.

One thing that hasn’t changed is the email list – the backbone of every email campaign. A human being, not an AI algorithm, can still help you find the best email list for your business.

There are important considerations to make before you buy a list – like how often is the list updated, validated, and verified? How big is the database? What is the accuracy rate? And most important – are the lists segmented into categories applicable to your business? You could get flagged or spammed if you don’t have a targeted list.

After researching and comparing stats and data, we came up with a new list of the top 5 best email list companies for 2023:
