Connect HubSpot to ActiveCampaign

What This Integration Does

This integration synchronises contacts, deals, and lifecycle data between HubSpot CRM and ActiveCampaign so the sales team and the marketing automation engine work from the same record. Contacts created in HubSpot appear in ActiveCampaign with the right tags and list memberships, automations in ActiveCampaign update HubSpot deals as they progress, and the lead scoring used in one platform informs the other.

It exists because businesses often pick ActiveCampaign for its automation depth and HubSpot for its sales pipeline, and end up with two systems that disagree about every customer.

The Workflow

When a new contact is created in HubSpot (usually from a form fill, sales rep entry, or a list import), the integration syncs them to ActiveCampaign, applying tags based on the HubSpot source property, lead status, and any custom fields configured to flow. If the contact already exists in ActiveCampaign, the existing record is updated rather than duplicated, with HubSpot’s data taking precedence on the agreed fields.

A specific chain: a HubSpot deal moves from “Demo Booked” to “Demo Completed” after the sales rep updates the stage. The integration fires that stage change to ActiveCampaign as a custom event, which triggers a post-demo automation. A follow-up email goes out with the meeting summary, a calendar reminder fires to chase if no reply within four working days, and a tag is applied for the next nurture cycle. Meanwhile, when the contact opens the follow-up email and clicks through to the case study, ActiveCampaign’s site tracking captures the visit, increments the lead score in ActiveCampaign, and the integration writes the updated score back to HubSpot so the sales rep sees the engagement directly on the contact record.

Unsubscribes flow in both directions. A contact who unsubscribes in ActiveCampaign has their HubSpot marketing email subscription set to opted out, and the sales rep sees the change immediately so transactional outreach can continue without compliance risk.

Before and After

Before, the marketing team uploads HubSpot contact lists to ActiveCampaign weekly, sales runs queries to figure out who engaged with which campaign, and unsubscribes are reconciled monthly. At that point a few wrongly-sent emails have already gone out. Lead scoring exists in both platforms with no agreement between them.

After, the two systems behave like one. Sales sees ActiveCampaign engagement on the HubSpot contact record. Marketing automations respond to deal stage changes the moment they happen. Lead scoring agrees because one platform owns it and the other reads it.

Who Needs This

Mid-market businesses running ActiveCampaign for marketing automation alongside HubSpot CRM for sales. This is common where the business adopted ActiveCampaign before HubSpot or values ActiveCampaign’s automation builder over HubSpot’s native marketing tools. The trigger is usually a sales-marketing alignment exercise that exposes how badly the two platforms are out of sync.

How We Build This

We build this against the HubSpot CRM API and the ActiveCampaign API, with a bi-directional sync engine that tracks last-modified timestamps to prevent loops. Field mapping, ownership rules, and the list of “always wins” fields per platform are agreed up front. See HubSpot API Integration for the HubSpot capabilities involved.

Get HubSpot and ActiveCampaign Connected

If you run sales in HubSpot and marketing in ActiveCampaign and the two never agree, we can build a custom integration that keeps them in step. We also connect HubSpot to Constant Contact and Salesforce to ActiveCampaign for teams on different CRMs. The integrations overview covers the full range of CRM and email connections we build.
