Integrations / Marketing Automation
Mailchimp
Server-side behavioural events delivered to a Mailchimp audience via the Marketing API Add Event endpoint. Signal matches each event to an existing contact by email (Mailchimp subscriber hash) and records a snake_case event name plus event properties for segmentation, merge tags, and automation triggers. Contacts are not created by this integration — they must already exist in the audience.
Datafly Signal delivers first-party events to Mailchimp server-to-server from infrastructure you control, using a pre-built blueprint that maps your event schema to the payload Mailchimp expects.
Why route Mailchimp through Datafly Signal
Profiles update from the server, not the browser
Events reach Mailchimp even when a tracker blocker or a failed page unload would have dropped a client-side call, so the profile reflects what actually happened.
One consent decision governs every destination
Mailchimp is gated by the same consent state as the rest of your stack, so a withdrawal applies everywhere at once.
What ships in the blueprint
Mapped events
add_to_cartbegin_checkoutloginpagepurchasesearchsign_upview_itemVertical presets
Default. Each preset starts from a working configuration for that vertical rather than a blank field map.
Full field mappings, configuration fields, and troubleshooting are in the Mailchimp documentation.
Frequently asked questions
Does Datafly Signal integrate with Mailchimp?
Yes. Datafly Signal delivers first-party events to Mailchimp server-to-server from infrastructure you control, using a pre-built blueprint that maps your event schema to the payload Mailchimp expects. The integration is included in every deployment at no additional cost.
How is server-side Mailchimp tracking different from the Mailchimp tag?
The Mailchimp tag runs in the visitor's browser, so it is subject to ad blockers, tracking prevention, and page-unload races. Signal collects the event through a first-party endpoint on your own domain and delivers it to Mailchimp from your server, so delivery does not depend on browser conditions.
Which events can Signal send to Mailchimp?
The blueprint ships with mappings for add_to_cart, begin_checkout, login, page, purchase, search, sign_up, view_item. Any event in your schema can be mapped to Mailchimp through pipeline configuration without a code change.
Do I need to keep the Mailchimp tag on my site?
No. Signal delivers to Mailchimp from the server, so no client-side Mailchimp script is required on your site.
