splitforms sends every form submission to Mailchimp

Form submissions, routed automatically

splitforms connects your forms to Mailchimp and moves every submission across the moment it's received — no manual export, no copy-paste.

Your leads are never lost

Every submission is emailed to you and saved to a searchable dashboard, so the lead is captured even if Mailchimp is unreachable.

No per-integration fees

Connecting Mailchimp to your forms is included in your plan — no add-on charge and no per-message billing from splitforms.

Example: form markup

Send form submissions to Mailchimp from plain HTML.

The form posts to https://splitforms.com/api/submit. The Mailchimprouting is configured in the splitforms dashboard against the form's access key — there's no client-side Mailchimp-specific code in your HTML.

  <input type="email" name="email" placeholder="[email protected]" required />

How it works

How to send form submissions to Mailchimp.

Here's how to send form submissions to Mailchimp in 5 steps — no code required, and most teams finish in a couple of minutes.

Step 1

In SplitForms, open Dashboard -> Integrations -> Mailchimp and choose the form that should receive Mailchimp events.

Step 2

Copy the Marketing webhook URL for audience/contact events, or the Transactional webhook URL for Mailchimp Transactional/Mandrill email activity.

Step 3

For Marketing, open Mailchimp -> Audience -> Settings -> Webhooks, create a new webhook, paste the SplitForms URL, and select the contact events you want.

Step 4

For Transactional, open Mailchimp Transactional -> Webhooks, add a webhook, paste the SplitForms URL, and choose delivered, open, click, bounce, spam, reject, or unsub events.

Step 5

Save the webhook and send a test event. Mailchimp events will show up as SplitForms dashboard entries for that form.

How teams use it

How do teams send form submissions to Mailchimp?

Copy a SplitForms webhook URL, paste it into Mailchimp, and capture audience changes or transactional email activity without OAuth, API keys, or a developer app. Prefer a plainer destination? The same form can also send form submissions to email or forward them to any webhook.

  • Delivered over an outbound webhook
  • Keep an audit trail of Mailchimp subscribes, unsubscribes, email changes, and cleaned contacts beside your website form leads.
  • Capture transactional email opens, clicks, bounces, and spam complaints from Mailchimp Transactional.

Why splitforms

Do you need a separate tool to send form submissions to Mailchimp? No.

OAuth is smoother but heavier; the SplitForms copy-paste URL gets most users connected in two steps. splitforms is free for 200 submissions total, $5/mo on Pro, or $59 for a 3-year plan (15,000 submissions/month, 36 months of access), with no per-integration add-on fees.

  • Let a non-technical customer connect Mailchimp by copying one URL instead of creating OAuth apps or sharing API keys.
  • Route Mailchimp audience changes into the same dashboard your team already uses for inbound lead review.
  • Test a Mailchimp integration before investing in a full two-way OAuth sync.

Common questions

Mailchimp form integration questions.

View all FAQs
Does this require a Mailchimp API key?

No. This setup is inbound-only: Mailchimp sends events to a SplitForms webhook URL. The user copies the URL from SplitForms and pastes it into Mailchimp. No OAuth app, client secret, or Mailchimp API key is needed.

What is the difference between Marketing and Transactional webhooks?

Marketing webhooks are for audience/contact changes such as subscribe, unsubscribe, profile update, email change, and cleaned contacts. Transactional webhooks are for Mailchimp Transactional/Mandrill message events such as delivered, open, click, bounce, spam, reject, and unsub.

Can SplitForms create the Mailchimp webhook automatically?

Not in this simple copy-paste flow. Automatic creation would require OAuth for Marketing and a Transactional API key for Mandrill. The copy-paste flow is intentionally simpler for users who just want to connect in a couple of steps.

Where do the Mailchimp events appear?

They are saved against the selected SplitForms form as dashboard entries with source, product, event type, email, list or message identifiers, and the important event metadata.

Is the webhook URL private?

Yes. Treat the copied URL as a secret because it identifies the SplitForms form. If it leaks, regenerate the form access key or create a fresh form and replace the URL in Mailchimp.

Does this also add SplitForms form submissions to a Mailchimp audience?

No. This page covers Mailchimp -> SplitForms webhooks. Sending SplitForms form submissions into a Mailchimp audience is a separate outbound workflow that usually uses Zapier, Make, or a small API relay.
