Key ActiveCampaign Salesforce Integration Limitations:
1. No Salesforce Classic Support:
The integration works exclusively with Salesforce Lightning Experience. Organizations still using Salesforce Classic must upgrade before implementing ActiveCampaign integration. This can be a significant barrier for enterprises with legacy implementations or customizations built for Classic. Compare this to native Salesforce email tools that work across all Salesforce editions.
2. No Historical Data Sync:
ActiveCampaign does not support one-time historical sync. Only new or updated records sync after integration setup. Existing contacts, leads, and Opportunities in Salesforce won't automatically import to ActiveCampaign. Workaround: To sync existing Opportunities, you must manually edit one of the four supported fields (Opportunity Name, Amount, Stage Name, Expected Close Date) to trigger a sync. For contacts/leads, use CSV export/import or manually update records to trigger syncing.
3. Mandatory Bi-Directional Sync:
It is not possible to disable either sync direction—you cannot configure a one-way sync. Both ActiveCampaign-to-Salesforce and Salesforce-to-ActiveCampaign syncs are always active. To completely stop syncing, you must uninstall the entire ActiveCampaign package from Salesforce, which removes all packaged components, including page layouts, permission sets, and sync jobs. This creates similar challenges to Mailchimp Salesforce sync problems.
4. Salesforce API Call Limits:
Data syncs from ActiveCampaign to Salesforce run in batches due to Salesforce's API limitations, which vary by edition tier. Batches execute every 10-11 minutes or when 100 contacts are updated (whichever comes first). High-volume organizations may find this sync frequency insufficient for real-time marketing automation needs. Organizations must monitor their daily API call usage to avoid exceeding limits.
5. Limited Custom Object Support:
The integration primarily supports standard objects: Contacts, Leads, Person Accounts, Accounts (Enterprise only), and Opportunities. Salesforce custom objects do not sync directly to ActiveCampaign. Opportunities sync as custom objects in ActiveCampaign, but with limited functionality—only four fields are supported by default (Opportunity Name, Amount, Stage Name, and Expected Close Date), plus up to 20 additional custom field mappings. This differs from native solutions like MassMailer that support any Salesforce object.
6. One-Way Opportunity Sync:
Salesforce Opportunities sync only from Salesforce to ActiveCampaign (one-way). Changes made to Opportunity custom objects in ActiveCampaign do not sync back to Salesforce. Each Opportunity must have a Primary Contact with an ActiveCampaign ID to sync. Opportunity field mappings cannot be edited or removed once saved—you can only add additional custom field mappings.
7. Deletion Handling Issues:
Deleting a contact or lead in Salesforce does not delete the corresponding record in ActiveCampaign. Worse, if the deleted Salesforce record is subsequently edited in ActiveCampaign, the sync re-creates the contact/lead in Salesforce. To prevent re-creation, you must manually remove Salesforce-related tags (added-to-salesforce-contact, added-to-salesforce-lead, etc.) from the ActiveCampaign contact record. This creates data hygiene challenges similar to managing bounce reports and opt-out compliance.
8. Email Address Requirement:
Every Lead, Contact, and Person Account in Salesforce must have an email address to sync to ActiveCampaign. Records without email addresses are skipped during sync, creating potential gaps in your marketing database. Proper email verification before syncing helps prevent issues.
9. Formula Field Restrictions:
Formula fields in Salesforce have one-way sync only—updates to formula field values don't trigger syncs to ActiveCampaign. You must manually edit another field on the record to trigger a sync update. Formula fields cannot be mapped to Last Name, Email, or Account name fields in ActiveCampaign. Boolean formula fields can only sync to checkbox fields in ActiveCampaign.
10. Enterprise Feature Lock:
Certain integration features are restricted to Enterprise subscriptions, including Account object syncing and advanced custom object capabilities. Organizations on lower-tier plans may find themselves limited in functionality, requiring unexpected upgrades to access needed features. See our Salesforce vs ActiveCampaign comparison for pricing details.
11. Manual Update Requirements:
You must manually update the integration when new versions are released. ActiveCampaign doesn't auto-update to avoid unexpected disruptions, but this means organizations can fall behind on bug fixes and new features. Always test updates in a sandbox environment before deploying to production.
12. Single Account Connection:
You can connect your Salesforce account to only one ActiveCampaign account. Organizations with multiple ActiveCampaign accounts or complex multi-org Salesforce structures face significant limitations.
Impact on Email Marketing Operations:
These limitations directly affect email deliverability and campaign effectiveness. The 10-11 minute sync delay means email tracking data isn't real-time, potentially affecting sales team follow-up timing. Without custom object support, organizations can't leverage their full Salesforce data model for email campaigns. The mandatory bi-directional sync can also complicate analytics by creating duplicate or conflicting data.
Common Workarounds:
- Use third-party tools like Zapier or SyncApps for additional sync flexibility
- Implement Process Builder or Flow to trigger syncs for specific criteria
- Export/import CSV files for historical data migration
- Create custom fields in Salesforce to mirror formula field values (updated via Flow) • Consider native Salesforce email solutions to eliminate integration complexity entirely
