Not on the list

AI left out Constant Contact — a tool many teams still rate. The brands AI leaves out tend to share one trait: content it can't read. Why AI snubs brands.

The contrarian pick

How to choose email marketing software

Budget and scalingStartups on tight budgets should consider Brevo or MailerLite. But watch out: Mailchimp and ActiveCampaign can get expensive as contacts grow.
Ease of useNon-marketers gravitate to Mailchimp's approachable UI and MailerLite's clean editor. Brevo's interface may feel less refined than top premium tools.
Automation depthIf lifecycle automation and lead scoring matter, ActiveCampaign excels. For simpler needs, Mailchimp and MailerLite provide adequate basic automations.
Ecommerce fitKlaviyo is the top choice for revenue-driven online sellers. Kit suits content-led businesses. Avoid all-in-one platforms if you only need email.
