ConvertKit
If you are looking to up the anti with your email marketing then ConvertKit is the choice for you. Other email marketing tools charge you for every user on your list so if you have multiple lists and the same user is on each one of them, then you are paying for that user multiple times. Not with ConvertKit though because they use a tagging system instead of lists. ConvertKit not only manages your email database but it also has landing page capabilities. And now they even offer a free plan for under 1,000 contacts…great for a new business!
