The request
“We have signup forms in the footer, the popup, and on the checkout page. We want each one to tag the subscriber in Mailchimp so we know where they came from.”
One list, no idea which form was working.
The approach
We configured each signup point to send a source tag to Mailchimp so the brand can see which placements drive signups and segment accordingly.
What we shipped
Source tagging on every signup form
Tags visible in Mailchimp
Segments available by source
