Lead attribution for Mailchimp
See exactly which marketing channels, campaigns, and keywords drive leads in Mailchimp.
The problem
Mailchimp stores your leads, but it can't tell you which marketing channel brought each one in. You know someone filled out a form, but not whether they came from Google Ads, a Facebook post, or an organic search.
How to set it up
SourceTag captures attribution data on your website and populates hidden fields in your forms. When the form submits, that data flows into Mailchimp alongside the lead's contact details. You get channel, source, campaign, click IDs, and more in every contact record.
Install SourceTag on your website
Add the script tag to your site header, or install the WordPress plugin.
Create custom fields in Mailchimp
Add custom contact/lead fields in Mailchimp for the SourceTag data (st_fc_channel, st_fc_detail_1, etc.).
Add hidden fields to your forms
Add hidden fields to your form builder matching the SourceTag field names. See the setup guide for your specific form builder.
Test with UTM parameters
Visit your site with ?utm_source=test&utm_medium=cpc, submit a form, and check the contact record.
