🔍How to Detect Mailchimp on a Website
There are several ways to identify whether a website is using Mailchimp.
Use a Technology Detection Tool Recommended
The fastest and most accurate method. TrueTechFinder analyzes HTML structure, script files, and DOM patterns to detect Mailchimp instantly.
Try TrueTechFinder freeCheck Page Source Code
Mailchimp leaves distinctive patterns through email subscription forms, scripts, and tracking pixels embedded in websites.
- list-manage.com/subscribe/post
- us{N}.list-manage.com/subscribe/
- mc.us{N}.list-manage.com
- chimpstatic.com/mcjs-connected/
- cdn-images.mailchimp.com/
- mailchimp.com/signup-forms/
- mc-embedded-subscribe-form class
- data-link='not yet determined'
- mailchimp-embedded-subscribe
- mailchimp.com/track/open
- Mailchimp tracking pixel patterns
Use Browser Developer Tools
Open DevTools (F12), check the Network tab for Mailchimp-specific script filenames, request headers, and DOM attributes that reveal the underlying technology.
The list-manage.com domain in form action attributes is the most reliable Mailchimp fingerprint, as it is unique to Mailchimp's subscription infrastructure.
How to Detect Mailchimp Manually
Mailchimp's subscription forms and tracking scripts leave clear markers in website source code:
Search Page Source for list-manage.com
View source (Ctrl+U) and search for 'list-manage.com'. Email subscription forms using Mailchimp will have form action URLs pointing to {username}.us{N}.list-manage.com.
Look for mc-embedded-subscribe-form
Search the page source for 'mc-embedded-subscribe-form' — this CSS class is applied to all standard Mailchimp embedded signup forms.
Check for chimpstatic.com Scripts
Look for script tags loading from chimpstatic.com. This is Mailchimp's CDN for embedded form validation and functionality scripts.
Inspect Email Links
If you receive emails from the site, check the link tracking domain. Mailchimp tracking URLs pass through list-manage.com or campaign.{domain} redirect patterns.
The combination of mc-embedded-subscribe-form class and list-manage.com form action is unambiguous evidence of a Mailchimp integration.
