A creator who writes in one tool and sends in the other
A writer keeps paid-subscriber emails in MailerLite and public newsletters in Kit. A buyer gets both the Kit tag and the MailerLite group, and a refund takes both away.

Native integration
A Kit tag and a MailerLite group for the same buyer, added on purchase and removed together on a full refund.
No credit card required. No coding required.
Kit (ConvertKit)
MailerLitePlandalf does not sync Kit (ConvertKit) with MailerLite, but both are native, so one sequence can tag the buyer in Kit and add them to a MailerLite group. The Remove access on refund template then handles both in a single sequence.
| Event | From and to | Through | What happens |
|---|---|---|---|
| Checkout completed | Plandalf → Kit | Native step | Tag Subscriber with a Customer tag, then Add Subscriber to Sequence for onboarding. |
| Checkout completed | Plandalf → MailerLite | Native step | Find or Create Subscriber, then Add Subscriber to Group. Run the first step's test so the group step can read subscriber_id. |
| Invoice refunded | Plandalf → Kit | Native step | Remove Tag from Subscriber in the template, with Email Address already set to {{trigger.customer_email}}. |
| Invoice refunded | Plandalf → MailerLite | Native step | Remove Subscriber from Group in the same sequence. It looks the subscriber up by email and leaves them in your MailerLite account. |
| Subscriber joined form | Kit → MailerLite | Native step | A Kit form trigger starts a sequence that adds the person to a MailerLite group, which can start a MailerLite automation. |
Connect both apps before you add the template, because it only adds steps for apps already connected.
In Automation, Marketplace, connect Kit with a V4 key and MailerLite with a token from the current MailerLite.
Create the sequence on Plandalf, Checkout Completed. Add Kit, Tag Subscriber, then MailerLite, Find or Create Subscriber and Add Subscriber to Group.
Under Automation, Templates, add Remove access on refund for the same checkout. Plandalf opens a sequence with a step for each connected app.
Pick the Kit tag in Remove Tag from Subscriber and the group in Remove Subscriber from Group. Delete any other app's step you do not need.
Leave Full refunds only on. Run on test purchases lets a test card exercise the purchase path, but refunds of test purchases are skipped too, so check the refund sequence against the Events view with a real small refund of your own.

A paid trial often ends in a refund. The one template removes access in both tools, so a refunded person stops receiving customer-only emails from either.
