The Complete Guide to Integrating ActiveCampaign and Close for Email Marketing + CRM workflows.
Stop manually shuttling data. Connect your system of record directly to your workflow to automate lead sync & outbound automation in real-time. This guide details the architecture of passing payloads natively between ActiveCampaign and Close.

Why Integrate ActiveCampaign and Close?
B2B growth requires a delicate balance between scalable, top-of-funnel marketing automation and highly personalized, aggressive outbound sales execution. ActiveCampaign excels at the former, capturing leads and nurturing them through sophisticated email sequences based on behavioral triggers. Close CRM is purpose-built for the latter, equipping sales teams with built-in calling, SMS, and pipeline management for high-velocity outreach. When these two systems operate independently, the resulting data gap paralyzes revenue growth. Marketing has no idea which leads are actually converting into pipeline, and sales reps are forced to cold-call prospects without any context regarding the emails they’ve already received or the links they've clicked. Integrating ActiveCampaign with Close CRM bridges this gap, creating a unified, data-driven revenue engine. By syncing contact data bi-directionally, you ensure that your sales reps are always calling the warmest leads at the exact right moment. When a lead hits a specific lead score in ActiveCampaign, the integration can automatically create a new Lead in Close and immediately assign it to a rep's calling queue. Conversely, when a rep changes a Lead Status in Close (e.g., 'Bad Fit' or 'Not Interested'), the integration can automatically remove that contact from ActiveCampaign's aggressive promotional sequences, protecting your brand reputation and email deliverability.
Top Use Cases
Automated Marketing Qualified Lead (MQL) Routing
High-velocity sales teams cannot afford to dial cold lists when warm leads are available. Use ActiveCampaign's robust lead scoring to track engagement (e.g., opening emails, visiting the pricing page, downloading a whitepaper). Configure the integration so that the moment a contact's lead score exceeds a threshold (e.g., 50 points), the system automatically pushes that contact into Close CRM. The integration creates the Lead, populates their contact details, and assigns a specific 'To-Call' task for a Sales Development Rep (SDR), ensuring rapid response times for high-intent prospects.
Syncing Marketing Activity to the Sales Timeline
Before dialing a prospect, a sales rep needs context. The integration allows you to sync specific marketing events from ActiveCampaign directly into the Close Lead timeline as Custom Activities or Notes. If a prospect recently attended a webinar or clicked a link regarding a specific product feature in an ActiveCampaign email, the Close rep can see this history natively on the Lead page. This intelligence allows the rep to bypass generic discovery questions and immediately tailor their opening pitch to the prospect's proven areas of interest.
Halting Marketing Automation Upon Sales Engagement
Nothing frustrates a prospect more than receiving an automated marketing blast from 'The Team' on the same day they had a personal, 45-minute discovery call with an Account Executive. To prevent this, configure a sync trigger originating from Close. When a sales rep changes a Lead Status in Close to 'Engaged' or 'In Pipeline', the integration automatically pushes an update to ActiveCampaign, applying a specific 'Sales_Active' tag. ActiveCampaign is then configured to use this tag to instantly pause all top-of-funnel promotional email sequences for that contact.
Post-Sale Customer Onboarding Handoff
The integration's value extends beyond customer acquisition into customer success. When a Deal is marked 'Closed Won' in Close CRM, the integration can automatically tag the contact in ActiveCampaign as a 'Customer'. This tag acts as a trigger to pull the user out of all sales-oriented pipelines and drop them into a structured, 30-day post-sale onboarding email sequence in ActiveCampaign, delivering training videos, implementation guides, and customer support resources without requiring manual intervention from the sales rep.
Connection Capabilities
Prerequisites
- An active Close CRM account with administrator API access.
- An active ActiveCampaign account (Plus, Professional, or Enterprise plan).
- A middleware platform (like Zapier or Make) or a dedicated integration sync tool (like Outfunnel) to manage the bidirectional data flow and field mapping.
- A standardized, documented definition of when a Lead is ready to be passed from Marketing to Sales.
Step-by-Step Implementation Guide
Generate API Credentials for Both Platforms
To facilitate the secure transfer of data, you must generate API keys. Log into your Close account, navigate to Settings > API Keys, create a new key specifically named 'ActiveCampaign Integration', and copy it. Next, log into ActiveCampaign, navigate to Settings > Developer, and locate both your API URL and API Key. You will need all three pieces of information to authenticate the connection within your chosen middleware platform.
Define the System of Record and Data Hierarchy
Before building the workflow, determine which system acts as the source of truth for specific data points to prevent endless looping and data overwrites. Generally, ActiveCampaign should be the system of record for marketing engagement metrics (Lead Score, Email Opens, Tags), while Close CRM should be the system of record for core contact details (Phone Number, Title, Company Name) and pipeline stages. Document these rules so you know exactly which platform's data should 'win' during a bi-directional sync conflict.
Map Standard and Custom Fields
In your integration tool, establish the field mapping between ActiveCampaign Contacts and Close Leads. Map standard fields like First Name, Last Name, Email, and Phone Number. Crucially, ensure you map custom fields that drive your business logic. For example, create a custom field in Close called 'AC Lead Score' and map the incoming ActiveCampaign lead score to it. Conversely, create a custom field in ActiveCampaign called 'Close Lead Status' and map the outbound Close status to it. This structural alignment allows you to build powerful automations in both platforms based on the other's data.
Configure the Inbound Marketing-to-Sales Trigger
Build the workflow that feeds your sales team. In your middleware, set ActiveCampaign as the trigger. Do not trigger on 'New Contact Created' (as this will flood Close with unqualified newsletter subscribers). Instead, trigger on 'Contact Tag Added' or 'Lead Score Achieved'. When this threshold is met, configure the Close action step to 'Find or Create Lead' using the email address as the deduplication key. Add a final action step to 'Create Task' in Close, alerting the assigned SDR that a new hot lead is ready for outreach.
Configure the Outbound Sales-to-Marketing Trigger
Now, build the reverse workflow to keep marketing aligned with sales reality. Set Close CRM as the trigger, specifically listening for 'Lead Status Changed'. In the action step, configure ActiveCampaign to 'Update Contact'. The most effective way to communicate state changes to ActiveCampaign is by applying or removing specific Tags based on the new Close Status (e.g., if Close Status = 'Lost', add ActiveCampaign Tag 'Lost_Deal'). Use these dynamic Tags as the entry and exit triggers for your ActiveCampaign automations.
Test the Bidirectional Sync Rigorously
A bi-directional sync can easily cause infinite data loops if configured improperly. Create a test contact in ActiveCampaign and manually increase their lead score to hit your MQL threshold. Verify the Lead appears instantly in Close. Next, inside Close, manually change a data field (like their phone number) and update their Lead Status. Switch back to ActiveCampaign and verify that the phone number updated and the corresponding 'Sales_Active' tags were applied correctly. Monitor the integration logs in your middleware for 24 hours to ensure no recursive update loops occur.

Begin by authenticating your instances. If a native integration is unavailable, utilize a webhook relay with the API credentials from both platforms.
