M What is Mailchimp?
Mailchimp in plain English.

Why custom?
Beyond the default Mailchimp integrations.
Mailchimp is the email platform many businesses still default to. The default integrations cover the basics — we build the custom ones: feeding ecommerce events from non-Shopify stores, syncing CRM data with custom merge fields, and triggering campaigns from operational events.

How we build
Production-grade.
Not Zapier in a trench coat.
Every Mailchimp integration we ship handles failure properly: idempotent jobs, retry logic, dead-letter queues for unrecoverable cases, and observability so you can see exactly where data is at any moment.
Tested
Real test suite, real edge cases. Not just "it worked once."
Observable
You see what is happening — events logged, errors surfaced.
Maintainable
Documented, version-controlled, handed over properly.

FAQ
Common questions about Mailchimp integration.
Can Mailchimp integrate with WooCommerce or Shopify?
Yes — both have official connectors, and we build custom integrations where you need behaviour the defaults do not support (multi-store, custom event triggers, advanced segmentation).
Mailchimp vs Klaviyo — which should we use?
Klaviyo is purpose-built for ecommerce and wins for serious online stores. Mailchimp is simpler and broader, working better for service businesses, B2B, and content publishers.
