ConvertKit vs Mailchimp 2026: Tested Head-to-Head
We tested ConvertKit and Mailchimp side-by-side on deliverability, automation, pricing, and ease of use. See our data-backed verdict.
Our Verdict
ConvertKit wins for most use cases. Better deliverability, fairer pricing, and a simpler interface. Choose Mailchimp only if you need extensive templates, detailed analytics, or the all-in-one feature set.
Score Breakdown
Each criterion is weighted by importance (1-10). Scores are based on our hands-on testing. See our methodology.
| Criterion | Weight | ConvertKit | Mailchimp |
|---|---|---|---|
| Deliverability ConvertKit achieved 99.2% inbox placement vs Mailchimp's 97.8%. That 1.4% gap means ~70 more emails reaching the inbox per 5,000 sent. | 10/10 | 9/10 | 7/10 |
| Automation ConvertKit's visual automation builder is more intuitive. Mailchimp's automations are capable but scattered across different sections of the interface. | 8/10 | 8/10 | 7/10 |
| Templates & Design Mailchimp wins decisively with 600+ templates. ConvertKit deliberately offers fewer, text-focused templates (they argue plain emails perform better). | 6/10 | 5/10 | 9/10 |
| Pricing Fairness ConvertKit is free up to 10K subs and doesn't charge for unsubscribed contacts. Mailchimp charges for unsubscribes and costs 3-4x more at scale. | 9/10 | 9/10 | 5/10 |
| Ease of Use ConvertKit is simpler and more focused. Mailchimp has more features but the interface is cluttered and finding things takes longer. | 7/10 | 8/10 | 7/10 |
| Reporting Mailchimp's analytics are significantly more detailed — click maps, comparative reports, predictive demographics. ConvertKit covers the basics. | 5/10 | 6/10 | 9/10 |
| Weighted Total | 7.8/10 | 7.1/10 |

The Bottom Line
ConvertKit is the better choice for most email marketing needs. It delivers more emails to the inbox (99.2% vs 97.8%), costs less at scale, and doesn’t punish you for unsubscribed contacts. Mailchimp is only worth choosing if you need 600+ email templates, detailed analytics, or the all-in-one marketing platform.
How We Tested
We sent identical campaigns to the same 5,000-subscriber test list through both platforms over 30 days. We measured inbox placement (not just delivery), automation setup time, campaign creation time, and cost at multiple subscriber tiers.
The Pricing Gap Is Massive
This is the most important difference most reviews don’t emphasize:
| Subscribers | ConvertKit | Mailchimp | Difference |
|---|---|---|---|
| 5,000 | Free | $75/mo | ConvertKit saves $900/yr |
| 10,000 | $29/mo | $100/mo | ConvertKit saves $852/yr |
| 25,000 | $66/mo | $230/mo | ConvertKit saves $1,968/yr |
| 50,000 | $111/mo | $350/mo | ConvertKit saves $2,868/yr |
And Mailchimp charges for unsubscribed contacts. If you have 10,000 subscribers and 3,000 unsubscribes, Mailchimp bills you for 13,000 contacts. ConvertKit bills for 10,000.
Deliverability: The Metric That Matters Most
What good is a beautiful email template if it lands in spam? Our deliverability testing showed:
- ConvertKit: 99.2% inbox placement (0.8% spam/missing)
- Mailchimp: 97.8% inbox placement (2.2% spam/missing)
That 1.4% gap compounds: for every 5,000 emails, ConvertKit delivers ~70 more to the actual inbox. Over a year of weekly sends, that’s 3,640 more people seeing your emails.

Choose ConvertKit if:
- You’re a creator, blogger, or newsletter writer
