Email marketing delivers an average ROI of $42 for every $1 spent — the highest of any marketing channel. But that ROI depends on your emails actually reaching inboxes and engaging subscribers. The platform you choose directly impacts deliverability, open rates, and conversion.

1. Mailchimp — Best for Small Businesses
Mailchimp Standard
$20/month (500 contacts) • Free plan available
Mailchimp is the most recognized email marketing platform for good reason. It combines ease of use with powerful features in a way that works for businesses of all sizes. The drag-and-drop email builder is intuitive, with 100+ professionally designed templates that look great on every device.
The AI tools are genuinely useful: the Subject Line Generator suggests attention-grabbing subjects based on your content, Send Time Optimization delivers emails when subscribers are most likely to open, and the Content Optimizer scores your email and suggests improvements before sending.
Marketing Suite
Beyond email, Mailchimp now offers landing pages, social media posting, postcards, websites, and a basic CRM. The Customer Journey Builder creates automated multi-step workflows triggered by subscriber behavior. The Predictive Analytics feature identifies subscribers most likely to purchase.

ConvertKit (now rebranding to Kit) is designed specifically for creators: bloggers, YouTubers, podcasters, and course creators. The subscriber-centric model means you pay for unique subscribers, not contacts across multiple lists. The visual automation builder is the best we tested for creating complex subscriber journeys.
The free plan is extraordinarily generous: up to 10,000 subscribers with unlimited email sends. Landing pages, forms, and digital product sales are included on all plans. The plain-text email style that ConvertKit champions consistently achieves higher open rates than HTML-heavy designs.
