How to Connect ActiveCampaign with HubSpot CRM (2026)

Why Connect HubSpot and ActiveCampaign

HubSpot CRM and ActiveCampaign serve overlapping but distinct roles. HubSpot provides a free CRM with contact management, deal tracking, and basic marketing tools. ActiveCampaign excels at sophisticated email marketing automation, advanced segmentation, and multi-channel campaign orchestration. The typical user connecting these two tools is a business that started with ActiveCampaign for email marketing and later adopted HubSpot for its CRM and sales pipeline features, or a team that finds ActiveCampaign's automation builder more powerful than HubSpot's built-in email tools.

This integration is particularly useful for small-to-mid-sized businesses running HubSpot CRM Free or Starter and pairing it with ActiveCampaign for more advanced automation workflows than HubSpot's free tier provides. Marketing agencies managing clients across both platforms also benefit from keeping data synchronized between the two systems.

What This Integration Does

Connecting HubSpot CRM and ActiveCampaign enables the following data sharing and automation capabilities:

• Bi-directional contact sync: Contacts created or updated in either platform can be reflected in the other, keeping your CRM and marketing database aligned.
• Deal and pipeline data sharing: ActiveCampaign deals can inform HubSpot deal records, and HubSpot deal stage changes can trigger ActiveCampaign automations.
• Tag and list synchronization: ActiveCampaign tags and list memberships can be mapped to HubSpot contact properties or list memberships.
• Engagement data visibility: Email opens, clicks, and automation activity from ActiveCampaign can be surfaced in HubSpot contact records so sales reps see the full engagement picture.
• Form submission routing: HubSpot form submissions can trigger ActiveCampaign automations for follow-up sequences.

Native Integration vs Third-Party

There is no official native integration between HubSpot and ActiveCampaign built by either company. This is not surprising — both platforms compete in the marketing automation space, so neither has incentive to build a direct connector to the other.

To connect these platforms, you need a third-party integration tool:

• Zapier: The most popular option. Supports HubSpot and ActiveCampaign as both triggers and actions. Handles basic contact sync, tag management, and deal creation. Works well for event-driven workflows.
• Make (formerly Integromat): Offers more complex workflow capabilities including data transformation, conditional branching, and error handling. Better for multi-step workflows and higher-volume sync.
• n8n: Self-hosted alternative to Zapier with both HubSpot and ActiveCampaign nodes. Good for teams that want full control over their integration infrastructure without per-task pricing.
• SyncSmart by HubSpot: HubSpot's data sync tool supports some third-party CRMs but does not currently include ActiveCampaign as a native sync partner.
• Custom API: Both platforms have well-documented APIs. HubSpot's v3 API and ActiveCampaign's v3 API can be connected through custom middleware for maximum flexibility.

Step-by-Step Setup

The most common approach uses Zapier. Here is how to set up a bi-directional contact sync:

Step 1: Create a Zapier Account

Sign up at zapier.com if you do not already have an account. A free plan allows limited Zaps, but for production contact syncing you will likely need a paid plan to handle the volume and multi-step workflows.

Step 2: Connect HubSpot to Zapier

In Zapier, click My Apps in the left sidebar, then Add Connection. Search for "HubSpot" and click to connect. You will be redirected to HubSpot's OAuth authorization screen. Log in and select the HubSpot portal you want to connect. Grant Zapier the requested permissions (contacts, deals, companies, forms).

Step 3: Connect ActiveCampaign to Zapier

Similarly, add ActiveCampaign as a connected app. Zapier will ask for your ActiveCampaign API URL and API Key. Find these in ActiveCampaign under Settings > Developer. Your API URL looks like https://youraccountname.api-us1.com and the API key is a long alphanumeric string. Paste both into Zapier.

Step 4: Create a Zap for HubSpot to ActiveCampaign Sync

Create a new Zap with the following configuration:

• Trigger App: HubSpot
• Trigger Event: New Contact (or Updated Contact Property, depending on your needs)
• Action App: ActiveCampaign
• Action Event: Create or Update Contact

In the action step, map HubSpot fields to ActiveCampaign fields. Map email, first name, last name, and phone number at minimum. For custom fields, use the dropdown to find the matching ActiveCampaign custom field. If the field does not exist in ActiveCampaign yet, create it there first, then refresh the field list in Zapier.

Step 5: Create a Reverse Zap for ActiveCampaign to HubSpot

For bi-directional sync, create a second Zap:

• Trigger App: ActiveCampaign
• Trigger Event: New Contact or Updated Contact
• Action App: HubSpot
• Action Event: Create or Update Contact

Important: Add a filter step to prevent infinite loops. When Zap A updates ActiveCampaign, it can trigger Zap B, which updates HubSpot, which triggers Zap A again. Use a filter that checks whether the contact was updated by the integration (using a custom field flag or timestamp comparison) and stops the Zap if so.

Step 6: Test Both Zaps

Create a test contact in HubSpot and verify it appears in ActiveCampaign with correct field values. Then create a test contact in ActiveCampaign and verify it appears in HubSpot. Check that existing contacts are matched by email address rather than creating duplicates.

Best Automation Workflows

1. Lead capture to nurture sequence: When a new contact is created in HubSpot via a form submission, add them to an ActiveCampaign automation that sends a 5-email welcome and education sequence. Use ActiveCampaign's conditional logic to branch the sequence based on which HubSpot form they filled out.
2. Lead scoring to sales handoff: When an ActiveCampaign contact's lead score reaches your threshold, create or update the contact in HubSpot, set their Lifecycle Stage to "Marketing Qualified Lead," and create a task for the assigned sales rep to follow up within 24 hours.
3. Deal stage email triggers: When a HubSpot deal moves to "Proposal Sent" stage, trigger an ActiveCampaign automation that sends the contact a case study or testimonial email three days later to reinforce the value proposition during the decision period.
4. Re-engagement for lost deals: When a HubSpot deal is marked "Closed Lost," add the contact to a long-term ActiveCampaign nurture automation that sends monthly value-add content. If the contact re-engages (opens three or more emails), notify the sales rep via HubSpot task.
5. Customer onboarding: When a HubSpot deal is marked "Closed Won," trigger an ActiveCampaign onboarding automation with product setup guides, training resources, and satisfaction check-ins at 30, 60, and 90 days.

Data Sync Details

Sync frequency with Zapier depends on your plan. Free plans poll every 15 minutes. Paid plans poll every 1-5 minutes depending on tier. For true real-time sync, use Zapier's Instant triggers (available for some HubSpot events via webhooks) or build a custom webhook integration.

Common Issues and Troubleshooting

Infinite sync loops

The most dangerous issue with bi-directional sync via Zapier. Contact A updates in HubSpot, triggers a Zap to update ActiveCampaign, which triggers the reverse Zap to update HubSpot, and so on. This burns through Zapier tasks rapidly and can corrupt data. Solution: Add a custom field in both platforms (like "last_synced_by") that records whether the update came from the integration. Add a Zapier filter that stops the Zap if the field indicates the update was integration-triggered.

Duplicate contacts

If both Zaps run simultaneously for the same contact, duplicates can be created. Solution: Always use "Create or Update" actions (not just "Create") in both Zapier actions. Configure both HubSpot and ActiveCampaign to match on email address. In ActiveCampaign, this is the default behavior. In HubSpot, the "Create or Update Contact" action in Zapier will search by email before creating a new record.

Field type mismatches

ActiveCampaign custom fields and HubSpot properties have different data types. A date field in ActiveCampaign formatted as "MM/DD/YYYY" may not match HubSpot's expected "YYYY-MM-DD" format. Solution: Use Zapier's built-in Formatter step to transform date formats, number formats, and text casing before sending data to the destination platform.

Zapier task limits exceeded

High-volume contact databases can generate thousands of Zapier tasks per month, exceeding plan limits. Each contact create or update counts as a task. Solution: Use filters early in your Zaps to skip contacts that do not need syncing. Consider Make (Integromat) for high-volume scenarios, as its pricing is more favorable for large numbers of operations.

Alternatives

If Zapier does not meet your integration needs, consider these alternatives:

• Make (Integromat): More powerful workflow builder with better error handling and data transformation capabilities. Supports scheduled bulk sync scenarios that Zapier handles poorly. Pricing is more competitive for high-volume use.
• n8n (self-hosted): Open-source workflow automation with both HubSpot and ActiveCampaign nodes. No per-task pricing, but requires hosting and maintenance. Good for teams with technical resources who want full control.
• Pabbly Connect: Budget alternative to Zapier with lifetime deal pricing. Supports both platforms with basic trigger-action workflows.
• Custom API integration: Build a Node.js or Python application that uses HubSpot's API (v3, OAuth-based) and ActiveCampaign's API (v3, key-based) to sync data on your own terms. Host on AWS Lambda or similar for cost-effective serverless execution.
• Consolidate to one platform: Before investing in integration maintenance, consider whether you need both tools. HubSpot Marketing Hub Professional includes advanced automation comparable to ActiveCampaign. If you are paying for both, consolidating may save money and complexity.
