Several small products, two tools
A seller with a template pack and a workshop keeps a MailerLite group for each, plus a Mailchimp tag for each, so either tool can send a launch email to just that product's buyers.

Native integration
A group per product in MailerLite and a tag per product in Mailchimp, kept in step by Plandalf sequences.
No credit card required. No coding required.
MailerLite
MailchimpPlandalf does not sync MailerLite with Mailchimp, but both have native steps. A sequence can add a buyer to a MailerLite group and tag them in Mailchimp, and a new MailerLite subscriber can start a sequence that adds a Mailchimp contact. Only current MailerLite works, not Classic.
| Event | From and to | Through | What happens |
|---|---|---|---|
| Checkout completed | Plandalf → MailerLite | Native step | Find or Create Subscriber first, then Add Subscriber to Group with the subscriber_id it returns. A MailerLite automation that starts when someone joins the group takes over. |
| Checkout completed | Plandalf → Mailchimp | Native step | Add Tags to Contact with a tag for the same product, so a Customer Journey or segment can aim at its buyers. |
| Subscriber created | MailerLite → Mailchimp | Native step | Choose a Group on the trigger to fire only for one group. The trigger hands over email, name and groups, and the sequence runs Add or Update Contact. |
| Contact subscribed | Mailchimp → MailerLite | Native step | A sequence runs Find or Create Subscriber and Add Subscriber to Group, which keeps a MailerLite group topped up from the audience. |
| Invoice refunded | Plandalf → MailerLite | Native step | Remove access on refund pairs Remove Subscriber from Group with Remove Tags from Contact, so a full refund takes the buyer out of both. |
You need a MailerLite API token from the current MailerLite and a Mailchimp key.
In Automation, Marketplace, connect MailerLite with a token from Integrations, MailerLite API. Classic accounts will not connect.
Connect Mailchimp the same way, with the key including its data-centre suffix.
In My Sequences choose Plandalf, Checkout Completed and the offer, and pick a sample checkout on the Test tab.
Add Find or Create Subscriber with {{trigger.customer_email}} and run its test. Then add Add Subscriber to Group and choose subscriber_id from the previous step, not the email.
Add Add Tags to Contact for the audience, with a tag named after the same product.
Add Remove access on refund for the checkout, pick the group and the tag, and keep Full refunds only on. Test with Run on test purchases and your own email.
A seller with a template pack and a workshop keeps a MailerLite group for each, plus a Mailchimp tag for each, so either tool can send a launch email to just that product's buyers.
Everyone who subscribes in Mailchimp is added to a MailerLite group with its own automation, so the nurture emails come from the tool the seller prefers.
