Switching email platforms sounds simple until you’re staring at a billing screen wondering if you just paid for another month of a tool you’re not using anymore.
The Mailchimp vs ConvertKit debate fills thousands of comparison articles. Almost all of them focus on templates, pricing tiers, and automation builders.
Nobody writes the article you need when you’ve already decided to leave. The question at that point is more specific: which platform lets you cancel cleanly and take your data with you?
That’s the comparison I care about. Cancellation policies, refund windows, data exports, DNS cleanup, and suppression list portability tell you more about a platform than any feature matrix ever will.
Cancellation and Refund Policies for Mailchimp vs Kit
The exit experience starts at the billing screen, and these two platforms handle it differently enough that the timing of your cancellation changes what you pay.
Mailchimp Cancellation Process
Mailchimp lets you self-serve cancel through Account & Billing. The deletion kicks in immediately after the flow completes. No waiting period, no approval queue.
The catch? No refunds once a charge processes. If your billing cycle renewed two days ago and you cancel today, that payment is gone. There’s no proration and no 30-day grace period.
I would time a Mailchimp cancellation within the first 48 hours of a new billing cycle just to be safe, because the platform’s public documentation confirms charges are non-refundable once they process. Waiting until mid-cycle means paying for weeks of service you won’t use.
Kit (ConvertKit) Cancellation Process
Kit handles cancellation through Settings, then Account & Billing. One difference worth noting: the deletion request takes 24 to 48 hours to process, so it’s not instant like Mailchimp’s flow.
The bigger deal is Kit’s 30-day refund window. Payments made within the prior 30 days are eligible for a refund. That buffer matters a lot during a platform switch, because renewals sometimes hit at awkward moments mid-migration. A refund window turns a billing mistake into a fixable one.
Kit also offers free migration for accounts with 5,000 or more subscribers. That migration typically covers subscriber imports, tag mapping, and basic automation rebuilds. Mailchimp doesn’t offer anything similar when you’re moving away from their platform.
| Feature | Mailchimp | Kit (ConvertKit) |
|---|---|---|
| Self-serve cancellation | Yes, immediate deletion | Yes, processed in 24-48 hours |
| Refund policy | No refunds after charge | 30-day refund window |
| Free migration help | None | Available for 5,000+ subscribers |
| Support during cancellation | Chat/email on paid plans | 24/7 support access |
Kit’s refund window and migration program give it a clear edge for anyone worried about timing the switch incorrectly.
Data Export and Suppression Lists: The Part That Can Wreck Your Deliverability
Getting your contacts out is only half the job. The other half is making sure unsubscribed contacts follow you to the new platform as a suppression list. Skip this step, and you risk emailing people who already opted out. That’s a compliance problem and a deliverability killer.
Mailchimp Data Export
Mailchimp’s CSV export covers your entire audience, including segments, groups, and tags. Statuses like unsubscribed and cleaned contacts export into separate files, which means you’ll need to merge or map them manually during import.
The platform also has an account-level export that bundles campaigns and templates. Reports are downloadable too. An API endpoint exists for bulk exports if you’d rather script it.
One billing detail catches people off guard: unsubscribed and non-subscribed contacts still count toward your audience size until you archive them. That means you could be paying for contacts who will never receive another email from you. Archive those contacts before your next billing cycle hits.
Kit Data Export
Kit exports subscribers as a CSV with tags and custom fields included. The export is simpler because Kit bills based on active subscribers only. Deleted or unsubscribed contacts don’t inflate your bill.
Broadcast content can be copied manually, and templates tend to be text-forward, so recreating them on another platform takes less time than rebuilding a complex HTML Mailchimp template.
The takeaway on data portability: both platforms let you export what you need, but Mailchimp’s separate-file approach for unsubscribed contacts and its billing-for-inactive-contacts policy add extra steps. Kit’s export is more straightforward.
DNS and Domain Authentication Cleanup During a Switch
This is the part people forget about, and it can silently damage your email deliverability for weeks if handled wrong.
Removing Verified Domains from Mailchimp
Removing a verified sending domain inside Mailchimp is a direct process through their Domains settings. The platform documents the steps clearly. Remove the old authenticated domain inside Mailchimp only after your new platform’s DNS records are live and propagated.
Kit’s DMARC and Domain Guidance
Kit’s documentation recommends against removing verified sending domains purely for cleanup purposes. Live DNS records still govern future deliverability regardless of which platform you’re using. The correct sequence matters here.
The order of operations for a clean domain switch should look like this:
- Update DNS records to match the new platform’s DKIM and DMARC requirements first
- Rotate keys if either platform requires it during the transition
- Remove the old authenticated domain from the prior platform only after DNS changes have fully propagated
- Verify sending from the new platform with a small seed campaign before going live
Getting DNS wrong during a switch is one of the fastest ways to tank your open rates on the new platform. I think spending 72 hours verifying DNS propagation before sending anything is worth the wait, given that Kit’s own documentation warns against premature domain removal.

Rebuilding Forms and Automations After the Move
Platform switches don’t end at the data export. Forms need to keep collecting leads during the migration window, and automations rarely translate one-to-one between tools.
Gravity Forms and the Parallel Feed Strategy
If you’re running WordPress, Gravity Forms has official add-ons for both Mailchimp and Kit. The smart move is running parallel form feeds during the transition: the old feed stays active while the new one starts collecting contacts on the destination platform.
Map email, name, and custom fields identically between feeds. Replicate tags on the destination platform so segmentation logic doesn’t break.
Enable double opt-in during the transition window if your compliance policy requires confirmation for new contacts. Remove the old feed only after DNS and domain verification are complete.
Automation and Template Rebuilds
Automations almost never copy cleanly between platforms. Plan to rebuild core sequences and triggers inside the new tool. Even when the visual builders look similar, the underlying logic and timing rules differ.
A common mistake: forgetting to rebuild the “exclude new subscribers in welcome sequence” filter. That filter prevents double sends during the first few days after a subscriber joins. Miss it, and your new subscribers get the same email twice.
Template rebuilds are faster on Kit because the platform leans toward text-forward newsletter layouts. Mailchimp’s exportable templates help when layout preservation matters, but expect to spend time adjusting HTML if your templates use complex formatting.
Send a small internal seed campaign on the new platform before any public sends. This catches formatting issues, broken merge tags, and authentication problems before they reach real subscribers.
The Billing Trap That Costs an Extra Month
I think the single biggest cancellation mistake across both platforms is ignoring the pre-cancellation checklist. Every comparison article talks about features, but nobody walks through the financial traps that cost you an extra billing cycle.
The checklist that saves money before cancelling:
- Archive or delete stale contacts in Mailchimp, especially unsubscribes and non-subscribers, because they inflate audience size and billing
- Check monthly send caps or send blocks if a final campaign is scheduled, since overages can land after your last invoice
- Confirm add-on renewal dates, because some add-ons bill on a separate cadence from your main plan
- Set a calendar reminder three days before your renewal date to avoid a last-minute scramble
This pre-cancellation cleanup is something I’d recommend spending at least a full workday on before hitting the cancel button, specifically because Mailchimp’s billing documentation confirms that non-subscribed contacts count toward audience-based pricing.
So Which Platform Is Easier to Leave?
For solo creators and small newsletter teams, Kit is easier to cancel and switch from. The 30-day refund window, the managed migration for accounts over 5,000 subscribers, and the simpler subscriber export all reduce the risk of a messy exit.
Kit’s migration program handles the subscriber import and tag mapping that would otherwise eat hours of manual work.
Larger marketing teams with complex HTML templates and years of historical campaign reports can still leave Mailchimp cleanly. The path just requires more preparation: archiving non-sending contacts, exporting suppression files, and timing the domain removal to happen after DNS changes propagate.
What is the contrarian take that most comparison articles miss? I think comparing email platforms on features is backwards when you’re already planning to switch.
The exit policy matters more than the feature list at that point, and Kit’s refund window alone changes the risk profile of a mid-migration billing surprise from “expensive mistake” to “fixable inconvenience.”
Questions People Ask About Cancelling Mailchimp and ConvertKit
Q: Can I get a refund if I cancel Mailchimp mid-cycle?
Mailchimp does not offer refunds once a charge processes. The best strategy is cancelling within the first day or two of a new billing period. Set a calendar reminder ahead of your renewal date so you don’t accidentally pay for another full month.
Q: Does Kit charge for unsubscribed contacts?
No. Kit only bills based on active subscribers. Unsubscribed and deleted contacts don’t count toward your plan’s subscriber cap. This is a meaningful difference from Mailchimp, where unsubscribed contacts still count until archived.
Q: How long does Kit’s free migration take?
The managed migration typically covers subscriber import, tag mapping, and basic automation equivalents. Processing time depends on list size and complexity, but expect the team to handle the core transfer within a few business days for lists above 5,000 subscribers.
Q: Should I remove DNS records from Mailchimp before setting up the new platform?
No. Set up DNS records on the new platform first, verify propagation, then remove the old records from Mailchimp. Reversing this order can create a gap where neither platform has valid authentication, which damages deliverability for every email sent during that window.
Q: Can I run both Mailchimp and Kit at the same time during a switch?
Running parallel feeds through a form plugin like Gravity Forms is a common approach during transitions. Keep both feeds active until DNS and domain verification finish on the new platform, then deactivate the old feed. Just watch for duplicate subscriber entries during the overlap.
Conclusion
Kit’s refund policy and migration program make it the smoother exit for creators switching email platforms. Mailchimp’s export tools are solid, but billing for inactive contacts adds steps to every cancellation.
The order of operations during a switch matters more than the platform itself. Plan the exit before you start the switch, and neither platform will trap you.
