Mailchimp forms on Wix guide

Sync Mailchimp Wix signup forms to Sheets

Mailchimp's Wix integration adds email signup forms, popups, and embedded subscribe blocks to your site. LeadToSheet captures each signup and writes it to Google Sheets alongside UTM and page data.

CMS: Wix

Mailchimp's Wix integration lets you embed email signup forms, popups, and inline subscribe blocks that sync subscribers directly to Mailchimp audiences. While Mailchimp excels at email marketing, it does not offer a native Google Sheets export for individual form submissions. LeadToSheet captures each signup event at the browser level and writes it to a spreadsheet, giving you a real-time subscriber log with page URL and campaign attribution that Mailchimp's reporting dashboard lacks.

Implementation checklist

  1. 1

    Add the LeadToSheet SDK via Wix Custom Code

    Go to Settings → Custom Code → Add Custom Code in your Wix dashboard. Paste the script, select All Pages and Body – End placement. Mailchimp forms may appear on any page as popups or inline elements, so site-wide coverage is necessary.

  2. 2

    Embed Mailchimp signup forms on your Wix site

    Install the Mailchimp integration from the Wix App Market or paste Mailchimp's embedded form HTML into a Wix HTML embed element. If using the embed code method, the form renders in the page DOM where the SDK can detect it directly.

    Tip: Mailchimp popup forms injected via their JavaScript snippet render in the main page DOM, not an iframe, so the SDK captures them automatically.

  3. 3

    Submit a test signup and verify the sheet

    Visit the published site, submit a test email signup, and check your Google Sheet. Confirm the email address, any additional fields (first name, last name), the page URL, and timestamp are present.

Customization ideas

  • Track which Wix page generates the most signups

    LeadToSheet records the page URL with every submission. Filter your Google Sheet by URL to identify which pages on your Wix site drive the most Mailchimp signups and optimize your form placement accordingly.

  • Compare Mailchimp audience size with raw submission count

    Mailchimp deduplicates subscribers, but your Google Sheet logs every submission event. Compare the two to understand how many repeat signups you receive and identify pages where returning visitors re-subscribe.

  • Build a real-time signup dashboard in Google Sheets

    Use Google Sheets pivot tables and charts on your LeadToSheet data to create a live dashboard showing signup trends by day, page, and UTM campaign. Share the sheet with your marketing team for instant visibility.

Troubleshooting

  • Mailchimp embedded form not detected by the SDK

    If you pasted Mailchimp's form HTML into a Wix HTML embed element, the form should be in the page DOM. If it is not detected, verify the form uses a standard HTML form element. Some Mailchimp embed code versions use JavaScript that renders after the SDK scans; add a short SDK initialization delay or contact support.

  • Mailchimp popup blocked by Wix cookie consent banner

    Wix's cookie consent banner can delay third-party script execution. If the Mailchimp popup does not appear, ensure the Mailchimp script is not categorized as a marketing cookie that requires consent. Adjust your cookie consent settings in the Wix dashboard.

  • Wix Editor preview does not show Mailchimp popups

    The Wix Editor preview does not execute Custom Code or third-party popup scripts. Publish your site and test Mailchimp popups on the live URL. This applies to both the popup forms and the LeadToSheet SDK.

Frequently asked questions

Why not just export subscribers from Mailchimp directly?
Mailchimp's export gives you a point-in-time list without page URLs, submission timestamps, or UTM attribution for each signup. LeadToSheet gives you a real-time log with full context for every individual signup event.
Does LeadToSheet interfere with Mailchimp's subscriber sync?
No. LeadToSheet captures the browser-side form submission event independently. The Mailchimp integration continues to sync subscribers to your audience as normal.
Can I track both Mailchimp signup forms and Wix Forms with one SDK install?
Yes. A single LeadToSheet SDK snippet in Wix Custom Code captures submissions from all form types on your site, including Mailchimp embeds and native Wix Forms.
