iContact and ConvertKit are both email marketing services designed to help businesses reach their customers and manage their email campaigns. The main difference between the two is the type of user experience they provide. iContact is a more traditional email marketing service which allows you to create, send and track email campaigns, as well as view detailed statistics. It is focused on sending campaigns in bulk and giving you a lot of control over the various components, from the design and content to the delivery and timing. Convertkit on the other hand, has a more modern and user-friendly focus. While it still allows you to create campaigns, it has a simplified dashboard and more automated features. It also has features specifically designed to manage individual subscribers and their preferences. Ultimately, the choice of which service to use comes down to the user preference and the specific needs of their business.
