No coding required. **Webflow** **Mailchimp** ## Does 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 WebflowPlandalf Checkout embed 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 PlandalfMailchimp 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 PlandalfMailchimp 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 MailchimpPlandalf 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 PlandalfMailchimp Native step The Remove access on refund template runs Remove Tags from Contact once the invoice is fully refunded in Stripe. ## Send Webflow buyers into a Mailchimp audience You need a Mailchimp API key, an audience for buyers, and a Webflow site published with the Plandalf script. 1. ### Install the checkout on Webflow Paste your Plandalf SDK script into Site settings, Custom code, Footer code. On the button, add the custom attribute `data-plandalf-present` set to the offer slug, publish, and open the live page signed out to check the amount. 2. ### Create a Mailchimp key In Mailchimp go to Extras, API keys and click Create A Key. Copy the whole key including the data centre part after the dash, such as `-us21`. 3. ### Connect Mailchimp In Plandalf open Automation, Marketplace and connect Mailchimp under Available now. Paste the key into API Key and wait for Mailchimp connected. 4. ### Add the contact and tag Create a sequence on Checkout Completed for the Webflow offer. Add Mailchimp, Add Tags to Contact, pick the Audience, set Email Address to `{{trigger.customer_email}}` and add a tag such as Webflow buyer. Leave Status for New Contacts on Subscribed only if buyers agreed to marketing email. 5. ### Record the event Add Mailchimp, Record Event with Event Name `purchased_course` and an Event Properties pair of `plan` and `{{trigger.line_items_summary}}`. In Mailchimp build a Customer Journey that starts on the same event name. 6. ### Test with a test card Switch on Run on test purchases, buy from the published Webflow page with a Stripe test card, and check the contact, tag and journey in Mailchimp. Switch the setting off afterwards. ## What sellers do with Webflow and Mailchimp ### Webflow portfolio sites selling presets A photographer sells Lightroom presets from a Webflow page and tags each buyer by pack. Mailchimp campaigns for the next pack go only to people with the earlier tag. ### 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. ## Guides for this pair - [Plandalf with Webflow](https://plandalf.com/platforms/webflow) - [Plandalf with Mailchimp](https://plandalf.com/platforms/mailchimp) - [Webflow setup guide](https://plandalf.com/docs/platforms/webflow) - [Mailchimp setup guide](https://plandalf.com/docs/integrations/mailchimp) - [Automations overview](https://plandalf.com/docs/integrations/plandalf) [Start your 14-day free trial](https://admin.plandalf.dev/signup) ## More from Webflow and Mailchimp - [**Stripe + Webflow**Style the button in Webflow Designer, add one custom attribute, and a Plandalf checkout charging your Stripe account opens from it.](https://plandalf.com/apps/stripe/integrations/webflow) - [**Webflow + ActiveCampaign**Webflow hosts the page, Plandalf takes payment, and a Send Webhook step can create the buyer in ActiveCampaign with a tag.](https://plandalf.com/apps/webflow/integrations/activecampaign) - [**Webflow + Kit (ConvertKit)**A Webflow page opens the Plandalf checkout, and a paid order tags the buyer in Kit and starts their emails.](https://plandalf.com/apps/webflow/integrations/convertkit) - [**Mailchimp + ActiveCampaign**One Plandalf checkout tags the buyer in Mailchimp with a built-in step and adds them to ActiveCampaign through a webhook call.](https://plandalf.com/apps/mailchimp/integrations/activecampaign) - [**Mailchimp + Drip**Mailchimp and Drip both have built-in Plandalf steps, so one checkout can fill both while you move your automations across.](https://plandalf.com/apps/mailchimp/integrations/drip) - [**Mailchimp + Flodesk**Tag the buyer in Mailchimp with a native step and put them in a Flodesk segment with a Send Webhook call, from the same checkout.](https://plandalf.com/apps/mailchimp/integrations/flodesk) Checked October 26, 2026 against Plandalf's own setup guides.
