The Bottom Line Up Front
For most small businesses and entrepreneurs, ConvertKit delivers better value and lower cost of entry. Mailchimp wins for enterprises with complex requirements and dedicated IT resources.
ConvertKit — Strengths
ConvertKit is the most accessible entry point in the email marketing space. Their free tier is genuinely functional, not crippled. The upgrade path is gradual rather than cliff-like, meaning you only pay for features you actually use. For affiliates: their program pays 30% recurring per referral.
Mailchimp — Strengths
Mailchimp wins in enterprise environments where compliance, custom integrations, and dedicated support matter more than cost. Large sales teams report better pipeline visibility. The 20% affiliate commission reflects their higher average contract value.
Who Should Choose What
Choose ConvertKit if you're a founder, small team, or growing business. The free tier covers most early-stage needs and the upgrade path is predictable. Choose Mailchimp if you have a 50+ person sales team and a budget that supports enterprise tooling.
Our Recommendation
Start with ConvertKit free. Migrate your data into it this week. Evaluate in 30 days. If you need features beyond what free provides, upgrade. You'll know by then whether Mailchimp's additional capabilities justify the cost difference.
