MailChimp and Convertkit are two of the most popular email marketing software tools, both of which can increase customer engagement and generate more revenue. The primary difference between the two services is the type of users they cater to. MailChimp is geared more toward small businesses who are new to email marketing and need a basic tool to get started, while Convertkit is designed more for advanced marketing professionals and growing businesses who need more analytics, automation, and segmentation features to better customize their messaging. Although both offer familiar features such as customizable newsletter templates, list management, segmentation, and reporting, Convertkit offers more features such as landing page builder, automation features with an intuitive user interface, and an API for integration with other services in order to give businesses more robust capabilities. Moreover, Convertkit also tends to be more affordable for growing businesses, whereas MailChimp increases their monthly fees as the number of subscribers or lists grow. Ultimately, the right email marketing service for any given business will depend on the companys unique needs and budget.
