A Flexible Sync Architecture Built for Your Business
Our custom integrations are engineered for flexibility. Unlike standard connectors that offer limited functionality, we allow you to connect HubSpot to Mailchimp in a way that mirrors your specific business logic.
Built for Your Business Process
We build the HubSpot Mailchimp sync around your requirements, mapping custom objects and handling complex data transformations that out-of-the-box tools cannot.
- Bi-Directional & Uni-Directional Sync: You control the data flow. Push HubSpot contacts to Mailchimp, pull Mailchimp activity into HubSpot, or keep both platforms perfectly in sync with a true two-way connection that native tools lack.
- Real-time & Scheduled Syncs: Trigger updates instantly when a record changes (e.g., a new Mailchimp subscriber) to eliminate the data delays common in native connectors. Or, run high-volume batch syncs nightly to align systems.
- Custom Sync Logic & Triggers: We go beyond basic field mapping. We can transform data (e.g., 'Lifecycle Stage' in HubSpot becomes a specific 'Tag' in Mailchimp) based on your unique rules.
- High-Volume Data Handling: Our architecture is built to scale, reliably processing hundreds of thousands of records without hitting API limits or slowing your systems down.
Comprehensive Object & Field Mapping
We sync all the data that matters. Our solution maps the full breadth of your GTM data, including custom properties, to ensure a seamless HubSpot integration with Mailchimp.

A failed integration is more than a technical problem: it's a drain on time, budget, and morale. We are the specialists that leading companies like MetLife trust to handle their most mission-critical data flows. We don't rely on fragile connectors or simplistic platforms because we know they can't handle enterprise scale. Our approach is built on robust, custom development and a deep understanding of both HubSpot and the systems you need to connect it to. Partnering with us isn't just another attempt; it's an investment in certainty.
Why Integrate IQ?
Our four pillars for delivering successful outcomes on complex projects.
Mastery of Complexity
We thrive on custom API integrations, multi-system migrations, and “messy data” that makes others pause. Full support for standard and custom objects across your stack is table stakes for us.
Pragmatic Innovation
Real problems, shipped solutions. Our proprietary Smart Ramp apps were developed to fill gaps in HubSpot capabilities and solve real-world customer problems. The same practical mindset powers our HubSpot AI Accelerator: We focus on data readiness and shipped outcomes, not shiny features.
De-Risking the Process
Complex projects demand clarity. Our Smart Process runs on an 8-12 week cadence with stage gates, transparent deliverables, and clear pricing. That’s how we maintain a 98.5% customer retention rate.
The Expert You Call
We’re a developer-led team of integration engineers, solution architects, and technical PMs. Clients describe us simply: 'the folks you call when something seems impossible.'

Frequently Asked Questions
Our HubSpot Mailchimp connector is fully bi-directional and customizable. The standard integration is primarily one-way (HubSpot to Mailchimp), often limited to basic fields (name, email), and subject to sync delays. We sync all custom fields in real-time.
Yes. We map any HubSpot property (standard or custom) to any Mailchimp merge field or tag. This allows you to use rich CRM data for segmentation, which native tools cannot do.
We perform a one-time historical backfill, migrating all past Mailchimp and HubSpot campaign activity (opens, clicks) onto the corresponding HubSpot contact records. Native tools typically do not sync retroactively.
Absolutely. We can sync HubSpot active lists directly to Mailchimp audiences or groups. This ensures your segments are always up-to-date without manual CSV imports.
We sync opt-outs bi-directionally and in real-time. An unsubscribe in Mailchimp will update the contact's opt-out status in HubSpot (and vice-versa) to ensure full compliance.
