ConvertKit vs Mailchimp (2026): Kit Pricing, Automation & Best Fit

ConvertKit is now Kit. The useful comparison is not whether Kit or Mailchimp has more features on a pricing page. It is whether your day-to-day email program revolves around publishing and selling to an audience, or designing campaigns and coordinating customer journeys across a business.

Quick verdict: choose Kit first for a creator-led newsletter, lead magnet or digital course. Shortlist Mailchimp for promotional campaign design, segmented customer communication and connected ecommerce workflows. For a store that relies on cart and order events, test the integration before subscribing to either.

Kit vs Mailchimp: the decision in 60 seconds

A solo writer sending a thoughtful weekly newsletter to 7,000 readers does not need the same system as a homeware retailer contacting 800 customers after purchases. The first case values publishing speed and a straightforward subscriber relationship. The second depends on reliable product, order, return and suppression data. Choosing on subscriber price alone ignores the costly part of both workflows.

ConvertKit is Kit: what the name change means

ConvertKit rebranded as Kit. They are the same product, not two competing options. Older online comparisons can still use the ConvertKit name and may describe plans or features that no longer match what new customers receive. Throughout this guide, Kit is the current product name.

Do not confuse a 14-day trial with the long-term plan. If a sequence works during a trial, test what happens when the trial ends. Your purchase decision should rest on functions available at the price you actually intend to pay.

Pricing: free plans and paid plans are not like-for-like

The published entry prices compare different audience sizes. Kit’s Creator entry tier is shown for 1,000 subscribers; Mailchimp’s Essentials and Standard entry tiers are for 500 contacts. Those amounts are starting points, not comparable quotes for the same database. Calculate both at today’s list size and at a plausible future size.

A free newsletter is not a free funnel

Kit’s free broadcast allowance is meaningful for a publisher who writes one issue and manually sends it to the list. It is not permission to assume unlimited free automated onboarding. Kit’s current help documentation reserves sequences and Visual Automations for paid plans.

Mailchimp Free can be adequate for signup testing, but its monthly send cap is tight. Four newsletters to 200 contacts need 800 sends, before any additional campaign. That is 300 more than the current 500-send monthly allowance. Sending limits can become the constraint before you reach the contact ceiling.

Budget using your actual list and send pattern

Work through two scenarios: today’s active and billable contacts, and next year’s credible count. Separately estimate newsletter sends, automated emails and promotions. Add integration subscriptions, implementation effort and any paid migration overlap. An apparently cheaper entry plan can become a worse operating choice if it cannot support the required workflow.

Use annual operating cost = recurring email plan + connected services + additional sending charges + migration or maintenance expense. Where time appears in the model, show who performs the work and what it actually costs; do not present invented productivity savings as facts.

Subscriber management and billable contact counts

Kit’s model emphasizes a single subscriber identity organized through tags and segments. For example, a course publisher might tag interest in a free portrait-lighting tutorial and separately identify customers who bought the course. The subscriber can sit in several segments without being treated as a different human for each interest.

Mailchimp also offers tags and segmentation. A claim that Mailchimp lacks tags would be inaccurate. The important decision is how you structure audiences and how that structure affects contact counts and workflows. Mailchimp explains that some non-subscribed and unsubscribed contacts can count toward billing, whereas archived and cleaned contacts do not.

For a migration, keep subscription permission separate from purchase history. Do not turn unsubscribed people back into marketing recipients merely because their records came across in a CSV. Export suppression data, identify who owns cleanup, and check the provider’s rules before importing a large database.

Automation: the real winner depends on what triggers your emails

Kit is a natural candidate for an educational funnel: someone downloads a lead magnet, enters a timed email sequence, then receives an offer for a workshop or course. The tool’s Visual Automation governs the path while sequences provide messages. The hard part is not drawing the path; it is handling a purchase, opt-out or other event in the middle of it.

Mailchimp’s Marketing Automation Flows can handle more elaborate campaign paths on its higher tiers. Essentials supports up to four flow steps, while Standard supports up to 200 and includes branching options. Those numerical limits matter, but they do not establish whether the trigger you need exists for your store or source of customer data.

Scenario 1: a course creator

Suppose a photographer offers a free lighting checklist and a $149 recorded course. The desired sequence is signup, checklist delivery, three useful lessons, then a purchase invitation. A sensible Kit Creator pilot must demonstrate three things: the signup enters exactly once, a completed purchase is recorded and the buyer stops receiving the sales pitch. The $149 price is a hypothetical example, not a reported conversion or revenue result.

If checkout software cannot signal a completed purchase, the flow may continue pitching buyers. That is a business defect, even if the editor makes the automation look tidy. Check the paid connector or integration you will actually use before choosing the platform.

Scenario 2: a store’s post-purchase program

Now consider a shop that wants a different message for first-order customers, repeat customers and people who buy a particular product category. Mailchimp Standard can be a candidate if the store integration provides accurate orders and product fields. First test which events are synchronized, then test exclusions after refunds, cancellations and repeat purchases.

A platform showing an “ecommerce integration” logo does not prove that it receives every required event. Your actual integration version, account plan and store architecture define what is possible. If a returns event is unavailable, document a fallback rather than writing automations that assume it exists.

Email design and the weekly workflow

Choose an editor by recreating the email you regularly publish. A text-first essay, a six-product sale and an event invitation place different demands on layout and approval. In a test account, make the same message in each platform, send it to desktop and mobile inboxes, then let the colleague responsible for weekly updates change one offer and one link.

Kit deserves a place on the shortlist when writing, publishing and reader relationships are central. Mailchimp deserves one when design templates, campaign approvals and product-oriented layouts matter. Neither style of email guarantees superior inbox placement or sales. Those results depend on audience, permissions, sending practices and the campaign itself.

Measure the routine production burden: how easily can someone replace a broken link, correct a price or schedule an issue? The “best editor” for your business is the one your team can reliably operate under deadline, not the one with more visible controls in a demo.

Ecommerce: do not confuse a store integration with a working retention system

Kit can be attractive when a creator sells a download, course or paid subscription alongside email. Those sales tools have checkout and transaction conditions separate from the newsletter price. Confirm geographic availability, payment fees and tax obligations directly before relying on them.

Mailchimp lists ecommerce connections including Shopify and WooCommerce. Before making a purchasing decision, verify whether your setup provides product identifiers, order totals, checkout abandonment data and buyer status when you need them. Historical data backfill, cancellation handling and duplicate customer records can differ.

• Submit a signup form and verify permission and source attribution.
• Create a test order and check the exact order, item and customer fields in the email platform.
• Trigger an email, then simulate the event that should cancel or suppress that email.
• Inspect repeat purchases, refunds and cancellations; note events the connector does not send.
• Check who sends transactional receipts so two systems do not email conflicting information.

If store lifecycle marketing is the main problem, consider a specialist along with Mailchimp. The StackScale comparisons of Omnisend vs Klaviyo and Omnisend vs ActiveCampaign provide alternative decision points. You can also review Omnisend’s ecommerce marketing tools; test it against your store rather than assuming it will outperform an existing setup.

Reporting, deliverability and sending reputation

This guide does not name a deliverability winner. Establishing one would require recent controlled tests using comparable senders, lists, authentication and content. An inbox-placement claim borrowed from an unrelated business would be misleading.

For a writer, pay attention to engaged readers, relevant clicks, replies and unsubscribes. For a course seller, check leads and purchases. For a store, compare attributed revenue with actual orders and understand attribution windows. Do not treat vendor dashboard totals as independent accounting records.

Before migrating, record a sensible baseline of normal campaign volume, delivery failures, engagement and unsubscribe levels. Verify domain authentication and use a controlled group of engaged subscribers after moving. Avoid switching sending domain, provider and send volume simultaneously if you want to know what produced a problem.

Which should your business choose?

No platform wins because of a universal feature count. List the requirements that cannot fail: permission handling, a key automated message, product order data, suppression after purchase, or the ability to keep costs within budget. Only compare design preferences and minor conveniences after both options pass those gates.

A seven-step pilot before you commit

Run these tests in the plan you intend to retain, with a small set of permitted test contacts. They are recommended tests for readers, not activities StackScale claims to have conducted.

• Capture: complete your real signup form and verify the recorded source and permission.
• Organize: apply interests and build a usable segment without duplicating people.
• Publish: create your actual weekly or promotional email, inspect mobile rendering and links.
• Automate: run the core welcome or offer sequence from start to finish.
• Exclude: simulate a purchase, unsubscribe or cancellation and check that inappropriate messages stop.
• Measure: locate the reporting view that will change a real business decision.
• Price: compare current and projected audiences, automation requirements, sends and external connectors.

Grade each test pass, fail or unresolved. Consent failures, broken purchase exclusions and missing critical store events are not small deductions in an average score; they are reasons to stop until fixed. If neither platform passes, widen the shortlist rather than rationalizing a poor fit.

Migration checklist: protect permission and automations

A contacts CSV is not the whole system. Inventory the forms, landing pages, tags, sequence timing, automation triggers, templates, API connections, unsubscribe records and old destinations before changing anything.

• Export contacts alongside the permission and suppression status that should survive the move.
• Map tags and segments; remove duplicates only with a clear, defensible matching rule.
• Rebuild one important workflow and run it completely before migrating the others.
• Update forms and old landing pages, then verify that public pages no longer send leads to the previous provider.
• Prevent both tools from delivering the same automated messages during any overlap.
• Keep an accessible rollback plan until critical journeys and billing have been verified.

If the new vendor advertises migration assistance, check exactly what it includes. Assistance importing contacts is not the same as rebuilding automations or integrating checkout. Assign responsibility for sign-off before canceling the original system.

Frequently asked questions

Is ConvertKit the same company as Kit?

Yes. ConvertKit adopted the Kit name. You should compare Kit’s current plans rather than treating ConvertKit as another product.

Does Kit really allow 10,000 free subscribers?

Its documented Free plan allows up to 10,000 subscribers and unlimited broadcasts, but sequences and Visual Automations are paid features.

Is Mailchimp Free suitable for a weekly newsletter?

It may be for a very small audience, but the 500-send monthly cap can be exceeded by four sends to 200 recipients.

Which service is cheaper at 1,000 contacts?

Do not use the advertised entry prices as an answer. Recalculate each plan for 1,000 billable contacts or subscribers, your monthly send volume and the required features.

Does Mailchimp offer tags and automation?

Yes. It offers tags and paid Marketing Automation Flows. Limits and branching abilities vary by tier.

Which should I use with Shopify or WooCommerce?

Test order and product synchronization, purchase exclusions and event reliability. Mailchimp is a candidate, not a guaranteed winner for every store.

Should I switch from Mailchimp to Kit?

Only if Kit solves a named limitation with a credible total cost and working migration plan. Avoid moving a functioning program merely because a free allowance looks bigger.

Final recommendation

Kit is the clearer first choice for a creator-led newsletter and a digital-product funnel, provided the paid automation tier covers the flow you need. Mailchimp is the stronger shortlist candidate for designed campaigns and broader customer marketing workflows, provided your integration supplies usable data and your contact and send tiers make financial sense.

For an online store, choose after testing the purchase event and the suppression logic. A working customer journey matters more than either vendor’s marketing adjectives. Check Kit’s current pricing and Mailchimp’s current pricing at your actual audience size, then run the pilot above before committing.
