When Mailchimp Makes Sense
Mailchimp is the right choice when: you are just starting out and need a free plan, you send simple broadcast newsletters, you have under 500 contacts, or you primarily need a beautiful email template library.
When ActiveCampaign Makes Sense
ActiveCampaign is the right choice when: you want automation that responds to subscriber behaviour (site visits, purchases, email opens), you need a built-in CRM alongside email marketing, you are running an e-commerce store or SaaS product, or you have hit the ceiling of Mailchimp's automation capabilities.
