Webflow
MailchimpDoes Webflow integrate with Mailchimp?
Plandalf does not sync Webflow forms or Webflow Ecommerce with Mailchimp. A Webflow button opens the Plandalf checkout; after payment a Plandalf sequence uses native Mailchimp steps to add the contact, apply tags and record an event. Mailchimp subscribe and unsubscribe events can start a Plandalf sequence.
What moves between Webflow and Mailchimp
| Event | From and to | Through | What happens |
|---|---|---|---|
| Checkout opened from a page | Webflow → Plandalf | The Plandalf script goes in the site's Footer code, and a button with the data-plandalf-present attribute opens the offer. Nothing is stored in Webflow. | |
| Checkout completed | Plandalf → Mailchimp | Native step | Add or Update Contact puts the buyer in the audience you pick. Add Tags to Contact marks what they bought. |
| Purchase event for a journey | Plandalf → Mailchimp | Native step | Record Event sends a named event, for example started_trial, and a Customer Journey that starts on that event name sends the emails. Events carry no revenue. |
| Contact subscribed | Mailchimp → Plandalf | Native step | Plandalf adds a webhook to the audience when you save the trigger. A sequence can then enrol each new subscriber in a promo, shown as a countdown on a Webflow page. |
| Invoice refunded | Plandalf → Mailchimp | Native step | The Remove access on refund template runs Remove Tags from Contact once the invoice is fully refunded in Stripe. |

Event and workshop sign-ups
A studio selling workshop seats on Webflow records an event per workshop, and a Customer Journey sends the joining details and a reminder sequence.
Limits and gotchas
- Mailchimp events carry no revenue and Plandalf does not send orders to Mailchimp's ecommerce API, so buyers will not appear as Mailchimp orders. Put the amount in an event property or merge field.
- Merge fields must already exist in the audience. Mailchimp does not create one the first time a value arrives, and the step fails with Mailchimp's message.
- A sequence that adds buyers to an audience also fires the Contact Subscribed trigger on that audience. Do not point both at the same promo enrolment without checking for double runs.
- Mailchimp allows 10 simultaneous connections per API key. Plandalf retries twice, so a busy launch may need a failed step re-run.
- Webflow Ecommerce is not involved. A product bought through Webflow's own cart will not reach Mailchimp through Plandalf.
Webflow and Mailchimp: common questions
- Does Webflow integrate with Mailchimp?
- Plandalf does not connect the two directly. A Webflow page opens a Plandalf checkout, and a sequence adds the buyer to Mailchimp after payment. For Webflow form signups, see Mailchimp's own integrations list.
- How do I connect Mailchimp to Webflow for buyers?
- Add the Plandalf script to Webflow's footer code, connect Mailchimp with an API key under Automation, then build a Checkout Completed sequence with Add Tags to Contact and Record Event.
- Can I add buyers to a Mailchimp Customer Journey from Webflow?
- Yes. Record Event sends a named event for the contact after the Webflow purchase, and a Customer Journey that starts on that event name takes over.
