How Field Mapping Works
Field mapping creates connections between Salesforce and ActiveCampaign data fields through a configuration layer that governs how information transfers during synchronization. According to the ActiveCampaign field mapping cheat sheet, the integration supports dynamic field mapping between ActiveCampaign contact fields and Salesforce lead and contact fields, with specific rules governing which field type combinations are supported.
Standard fields such as Email, First Name, Last Name, and Phone typically map automatically or with minimal configuration during the initial setup process. Custom field mapping requires more deliberate effort—Salesforce custom fields must be manually mapped to corresponding ActiveCampaign custom fields, and both systems must have the matching fields created before mapping can proceed. The integration supports bidirectional mapping where changes in either platform propagate to the other, though some field types, like formula fields, only support one-way sync from Salesforce to ActiveCampaign. Mapping configuration also determines which system serves as the master for each field during conflicts, with Salesforce treated as the primary source of information when mapped fields are updated in both platforms simultaneously.
Fields That Typically Map
Standard ActiveCampaign-Salesforce field mappings cover the core contact data that both platforms share. These include email address, which serves as the primary identifier for record matching, first name and last name, phone number, mailing address fields, company or account name, job title, email opt-out status for compliance synchronization, and lead source. Select custom fields also transfer with explicit configuration, though the scope of mappable custom fields depends on the data type compatibility between platforms. The ActiveCampaign Salesforce integration setup documentation details the standard lead and contact field mappings that are preconfigured during installation, along with instructions for extending mappings to custom fields.
Setting Up Field Mapping
Configuring ActiveCampaign-Salesforce field mapping begins by accessing the Salesforce integration settings within the ActiveCampaign application installed in your Salesforce org. Start by reviewing the default field mappings that the integration preconfigures for standard fields, ensuring they align with your data flow requirements. Next, create custom fields in ActiveCampaign that correspond to the Salesforce custom fields you want to synchronize, paying careful attention to data type compatibility between the two systems. Map each Salesforce field to its corresponding ActiveCampaign field through the Dynamic Field Mapping interface, then configure the sync direction for each mapped field—determining whether data flows from Salesforce to ActiveCampaign, from ActiveCampaign to Salesforce, or bidirectionally. Set conflict resolution rules that establish which system wins when the same field has been modified in both platforms between sync cycles. Finally, test all mappings with sample records before enabling the full synchronization to verify that data transfers correctly across edge cases including special characters, long text values, and picklist values.
Field Mapping Limitations
ActiveCampaign-Salesforce field mapping has significant limitations that organizations should evaluate before committing to this integration architecture:
Limited Field Types: Not all Salesforce field types map cleanly to ActiveCampaign equivalents. According to Salesforce field type documentation, complex fields like formulas, roll-up summaries, and lookup relationships often don’t transfer through standard integration connectors. Formula fields in particular only support one-way sync and cannot be mapped to required fields like Last Name, Email, or Account name in ActiveCampaign.
No Custom Object Fields: Field mapping is typically limited to standard objects such as Contacts and Leads. Custom object fields that many organizations rely on for membership records, patient data, or property listings don’t map directly, forcing organizations to create workarounds that add complexity and maintenance overhead.
Picklist Mismatches: Salesforce picklist values must match ActiveCampaign dropdown options exactly, or data may fail to sync entirely. Any new picklist value added in Salesforce requires a corresponding update in ActiveCampaign before records using that value can synchronize properly.
Character and Format Issues: Field length differences between platforms can truncate data during sync, and date or datetime fields may sync incorrectly due to format or timezone differences. These issues often go undetected until they cause visible problems in email personalization or campaign targeting.
Related Data Gaps: Data from related objects—such as Account fields displayed on Contact records, parent object data, and lookup relationship information—typically doesn’t sync through the integration, stripping away the relational context that makes Salesforce data powerful for targeted marketing.
Mapping Quantity Limits: Some integration configurations limit the number of custom fields that can be mapped. For example, Opportunity field mapping is restricted to four standard fields plus up to 20 custom fields, and once saved, Opportunity mapping configurations cannot be edited or removed.
Common Field Mapping Issues
Field mapping problems between ActiveCampaign and Salesforce typically manifest in several recognizable patterns, each requiring specific diagnostic approaches:
Data Not Syncing: When field data fails to transfer between systems, verify that the field mapping exists and is correctly configured in the Dynamic Field Mapping interface. Confirm that data types match between platforms—mapping a text field to a number field, for instance, will cause silent sync failures. Check the ActiveCampaign sync documentation to understand how sync frequency and batch processing may affect data transfer timing.
Truncated Values: When Salesforce field content is longer than ActiveCampaign accepts, data gets silently truncated during sync. Review field length limits in both systems and either adjust the ActiveCampaign field capacity or implement Salesforce validation rules to enforce compatible lengths before sync.
Picklist Sync Failures: Ensure all picklist values match exactly between Salesforce and ActiveCampaign, including spacing and capitalization. Add any missing values to ActiveCampaign dropdown fields before enabling sync to prevent data quality issues.
Opt-Out Not Updating: Verify that the unsubscribe field is mapped bidirectionally between platforms. Test opt-out synchronization thoroughly before production deployment, as compliance failures carry legal consequences when the unsubscribe status doesn’t propagate between systems.
Overwritten Data: Check conflict resolution settings when field values unexpectedly change. Ensure the master system is correctly designated for each field to prevent one platform’s data from inappropriately overwriting the other during bidirectional sync.
Field Mapping for Email Campaigns
Field mapping directly constrains the effectiveness of email campaigns sent through ActiveCampaign using Salesforce data. Personalization capabilities are restricted to mapped fields only—unmapped Salesforce data simply cannot appear in ActiveCampaign email template merge fields, limiting the depth of personalization available for email campaigns. Segmentation in ActiveCampaign is similarly constrained to mapped field data, meaning that Salesforce campaign lists and report-based criteria may not transfer to ActiveCampaign segments with full fidelity. Email automation and drip campaigns can only trigger on mapped field values rather than the full breadth of Salesforce data, and email sequences and follow-up sequences face the same personalization limitations imposed by field mapping constraints.
Best Practices for Field Mapping
Organizations that commit to ActiveCampaign-Salesforce field mapping should adopt disciplined practices to minimize synchronization issues. Maintain a comprehensive spreadsheet documenting all field mappings between systems, including data types, sync directions, and conflict resolution rules for each mapped field. Ensure Salesforce and ActiveCampaign fields use compatible data types before creating mappings, and standardize picklist values exactly between platforms before enabling sync to prevent data quality degradation. Test each mapping thoroughly with sample records that cover edge cases, including special characters, maximum-length values, and empty fields. Monitor sync logs regularly for mapping-related errors that may indicate silent failures or data quality issues. When adding new Salesforce fields, remember to create and map corresponding ActiveCampaign fields before expecting that data to appear in email campaigns or automation triggers.

No Maintenance: Adding Salesforce fields doesn’t require mapping updates, ActiveCampaign field creation, or data type compatibility checks—new fields are immediately available for personalization, segmentation, and automation.
When Field Mapping Fits
ActiveCampaign-Salesforce field mapping may work for organizations with simple data models that rely primarily on standard fields, existing heavy investment in ActiveCampaign workflows and automation that would be costly to recreate, use cases that don’t require custom object data or complex relational fields, and teams with dedicated bandwidth for ongoing mapping maintenance and troubleshooting. However, organizations with complex Salesforce implementations typically achieve better email deliverability and open rates with native solutions that access all data directly without the translation layer that field mapping introduces.
