My honest take
My honest take: Mailchimp for most founders, full stop. 62 vs 48 is a 14-point gap, and gaps that wide usually mean the loser has fundamental issues (pricing, ownership risk, or a missing capability) that show up later. Kit can still be the right call in narrow situations (creator-focused email platform formerly convertkit with tags, sequences and commerce), but if you're picking a primary tool, default to Mailchimp and don't second-guess.

The long answer
Why Mailchimp wins.
Mailchimp is email giant everyone starts with and eventually outgrows. Kit is creator-focused email platform formerly convertkit with tags, sequences and commerce. Both target email workflows, and the question we get most often is which one to commit to. Here is the honest answer based on our scoring across functionality, pricing value, ease of use, reliability, and founder fit.
Mailchimp wins clearly. 62 vs 48: a 14-point gap on Best Score. Across the five criteria we weight (functionality, pricing value, ease of use, reliability, founder fit), Mailchimp leads on most. Kit is still defensible if you fit one of the specific use cases below, but for a generalist founder it is the harder sell.
Where the gap shows up specifically: Functionality: Mailchimp (8/10) a stronger core feature set than Kit (2.9/10). Ease of use: Mailchimp (8/10) a faster path from sign-up to first result than Kit (3.7/10). Founder fit: Mailchimp (6/10) a better fit for solo and small-team founders than Kit (3.5/10). These are the differences that actually change a buying decision once you have used both for a real project.
On the ownership side, Mailchimp is recently acquired by Intuit. We weight ownership in Stack Score because it predicts pricing trajectory and continuity risk over 2-3 year horizons. Founder-led usually means slower price creep and more product continuity; PE-owned usually means the opposite.

Is the ownership situation a risk for either tool?

What's the migration cost if I'm already on the other one?
Migration cost depends on how deep you've integrated this category into your stack. For a project that uses Mailchimp or Kit as the primary surface (not just a small embedded feature), expect a half-day to a weekend of migration work plus a week of running both in parallel. Both tools support data export. Run a fresh audit on your current stack before deciding the switch is worth it: audit my stack with both options.

Real-world scenarios
Which one wins in your specific situation.
- You're a solo founder shipping your first product: Mailchimp is the cleaner choice. Less setup, fewer enterprise-only features locked behind upgrades, pricing that makes sense for one seat.
- You already use Mailchimp and it's working: don't migrate. The score gap (14 points) doesn't justify the disruption. Migration costs are real · half a day to a weekend of work plus a week running both in parallel.
- Your team is going from 5 people to 25 in the next year: Mailchimp has more headroom on functionality and reliability · the two things that break first under load.
Stack fit
How each fits inside a founder stack.
A tool you can't integrate is a tool you'll replace in six months. Here's how each plays with the rest.
Mailchimp
Mailchimp fits cleanly in a stack with Stripe, Beehiiv, Notion, Cal.com. If your stack already includes most of those, Mailchimp integrates without friction.
Kit
Kit fits the same kind of stack. If your existing stack leans toward Stripe or Beehiiv or Notion, Kit doesn't create integration debt either.
Final recommendation
For most founders, Mailchimp. The gap is wide enough that the loss-of-points reasons matter more than the win-points reasons. Default to Mailchimp unless you fit a specific edge case. If you're already on Kit and it's working, don't migrate. The cost of switching is real and the gain is small.
Bottom line
Mailchimp for most founders.
Mailchimp wins clearly. 62 vs 48: a 14-point gap on Best Score. The email giant everyone starts with and eventually outgrows. Kit is still a defensible choice if creator-focused email platform formerly convertkit with tags, sequences and commerce, but for most founders Mailchimp is the safer pick.
