Mailchimp

Integration

Mailchimp

Plandalf integrates with Mailchimp as a email, marketing, website, sdk platform.

What it does

Product surfaces

Where Mailchimp fits in the buying workflow

Integrations work best when the checkout surface, payment state, invoice record, and post-purchase automation all point at the same commercial object. These product screens show the Plandalf controls that should be configured before Mailchimp receives checkout, payment, tax, or workflow context.

The Numi offer editor showing layout, product, theme, automation, invoice, and settings controls.
The Numi checkout elements palette showing content, interactive, and selling blocks.
The Numi offer editor automation tab showing sequence controls beside the checkout canvas.

Purchase events can start follow-up

Mailchimp should fit into the work after checkout: fulfilment, records, CRM updates, support context, webhooks, and sequences.

The Numi offer editor showing hosted checkout mode controls.

Builder paths

Stack guides that use Mailchimp

Use these stack guides when a builder needs the whole path: sales surface, Plandalf offer, payment handoff, automation, fulfilment, records, and downstream integrations.

Overview

Mailchimp is an email marketing platform with Customer Journeys (a workflow builder), a contact database, and pre-built forms. For promos, merchants most commonly embed the countdown GIF into a campaign and enrol new subscribers via a Customer Journey that POSTs to the promo’s catch URL.

What Plandalf does here

  • Countdown in campaigns — a simple <img> tag using Mailchimp’s *|EMAIL|* merge tag serves a per-recipient animated GIF.
  • Journey-driven enrolment — Customer Journeys include a native Webhook action, so no middleware is required between Mailchimp and Plandalf.

Setup templates

Drop-in implementations

Copy-paste setups for the most common ways to wire Mailchimp into Plandalf.

promo · email

Drop the Plandalf countdown image into a Mailchimp campaign

Paste this <img> tag into a Code block in your Mailchimp campaign. *|EMAIL|* is Mailchimp's merge tag for the recipient's address — Mailchimp swaps it at send time, so each subscriber lands on their own deadline.

<img
  src="{{ promo.countdown_url }}?ref=*|EMAIL|*"
  alt="Time remaining on this offer"
/>

promo · automation

Enrol Mailchimp subscribers via Customer Journey

  1. In Mailchimp, go to Automations → Customer Journeys.
  2. Pick a starting point (e.g. Subscriber joins an audience or Subscriber added to a tag) and select the audience or tag that should enrol into this promo.
  3. Add an action: Webhook.
  4. URL:
    {{ promo.catch_url }}
    
  5. Method POST, content type application/json, body:
    {"email": "*|EMAIL|*", "ref": "*|EMAIL|*"}
    
  6. Publish the journey.

Integration methods

How Mailchimp connects to Plandalf

Each method below is the minimum viable setup. Pick the one closest to how you already use Mailchimp with checkout, payments, invoices, webhooks, API work, SDK checkout, and integrations.

  1. Method 1

    Embed a Plandalf buy button

    Drop the Plandalf embed script into a Mailchimp HTML block and tag any element with `data-plandalf-present` to open the configured flow on click.

    <script src="https://cdn.plandalf.com/embed.js" async></script>
    
    <button data-plandalf-present="offer_abc123">
      Buy now
    </button>
  2. Method 2

    Drop in a per-recipient countdown image

    Add an HTML block to any Mailchimp email and paste the Plandalf countdown URL. Mailchimp's merge tag `*|EMAIL|*` substitutes per recipient so each subscriber sees a timer pegged to their own deadline.

    <img
      src="https://cdn.plandalf.com/timers/{TIMER_ID}.gif?ref=*|EMAIL|*"
      alt="Time remaining on this offer"
      width="600"
      height="120"
    />
  3. Method 3

    Trigger a sequence from a form

    Point a Mailchimp form's webhook / POST URL at Plandalf's intake endpoint and every submission starts whatever sequence you've mapped to it.

    curl -X POST https://api.plandalf.com/v1/intake/mailchimp \
      -H "Content-Type: application/json" \
      -d '{"email": "{{ form.email }}", "source": "mailchimp"}'
  4. Method 4

    Enrol from an automation step

    Inside Mailchimp's automation builder, add a Webhook step that POSTs the contact to a Plandalf sequence catch URL. Use this to mirror Mailchimp journey logic into Plandalf without re-building the segmentation.

    {
      "email": "{{ contact.email }}",
      "sequence": "post-signup-onboarding",
      "source": "mailchimp"
    }
  5. Method 5

    REST API webhook

    For anything not covered by a native trigger, configure a Mailchimp webhook to POST to Plandalf. The payload is forwarded into the sequence as `${event}`.

    curl -X POST https://api.plandalf.com/v1/webhooks/mailchimp \
      -H "Authorization: Bearer $PLANDALF_API_KEY" \
      -H "Content-Type: application/json" \
      -d @event.json

FAQ

Common questions about the Mailchimp integration

Do I need a paid plan to use Mailchimp with Plandalf?

Plandalf itself is free to connect. Mailchimp's native webhook step is on its paid tiers — on the free plan, route the trigger through Zapier instead, which still works end-to-end.

How long does setup take?

Under 10 minutes. OAuth (or paste an API key), pick the lists/segments you care about, and you're live. No code unless you want it.

Can I disconnect Mailchimp later without losing data?

Yes. Disconnecting only revokes the credentials — historical events Plandalf fired stay in your sequence logs, and Mailchimp's own records are untouched. You can reconnect any time and resume from the last seen event.

Does Plandalf store Mailchimp data?

Plandalf stores the Mailchimp contact ID and the events Plandalf fired against that contact. Email content stays in Mailchimp; Plandalf doesn't mirror your audience or newsletter archive.

What if my email need isn't covered by the actions or triggers listed here?

Use the generic `mailchimp.custom_api_call` action or the inbound `mailchimp.webhook` trigger. Anything Mailchimp's REST API can do, a Plandalf sequence can drive.

Is there a usage limit?

Plandalf respects Mailchimp's API rate limits and backs off on 429s. For very high-volume use cases, ask about a dedicated worker pool.

Where do I find Mailchimp's own documentation?

Mailchimp's homepage at https://mailchimp.com links to their developer docs. For Plandalf-side questions about the Mailchimp integration, see the Plandalf docs.
