Still deciding between Constant Contact and MailerLite?
Constant Contact fits teams that want AI copy generation and event/payment features built into every plan starting at $20/month, plus access to 300 total integrations including Shopify. Its automation and A/B testing features expand as you move up to Standard and Premium, so it suits businesses ready to invest in a paid plan from day one. MailerLite fits smaller teams or those testing email marketing on a budget: its Free plan covers up to 250 subscribers with automation and a drag-and-drop builder included, and its A/B testing spans email, multivariate, forms, and landing pages without an upgrade. However, MailerLite's AI writing assistant is only available from the Comfort plan up. Choose Constant Contact if AI-assisted copywriting and ecommerce breadth matter from the start; choose MailerLite if you want to start free and only pay as your list and automation needs grow.
Compare current pricing and plan limits directly with each vendor before committing, since contact-based pricing and feature tiers can affect your total cost.
