Overview
Eagle CRM stores real estate sales data: contacts with lifecycle stages, companies with listings, deals in pipeline stages, contracts, and activity logs. Mailchimp stores subscriber records in Audiences with merge fields, tags, and segments — it has no concept of deals, pipelines, or opportunities. We migrate contacts, companies, and Eagle CRM custom fields to Mailchimp subscribers and merge fields using Mailchimp's REST API. Deal records, pipeline stages, contracts, and workflow automations have no Mailchimp equivalent and must be documented separately for rebuild. Our delta-pickup window captures any contacts modified during cutover before you pause the Eagle CRM sync. During the initial audit, we enumerate all object types and custom properties in your Eagle CRM instance. We then provision the target Mailchimp Audience and pre-create merge fields matching your field inventory. Contact-to-company relationships are resolved to a primary company per subscriber, with secondary associations preserved as tags. Owner assignments map to dedicated merge fields. A sample migration validates field-level accuracy before the full run commits. The delta-pickup window ensures any late-stage changes in Eagle CRM are captured before you switch off the sync. Deal data, pipeline stages, contracts, and workflow definitions export as JSON and CSV reference files for your team to rebuild outside Mailchimp.

Object mapping
Each row shows how a Eagle CRM object lands in Mailchimp, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Eagle CRM
Contact
Mailchimp
Subscriber (in Audience)
1:1Each Eagle CRM contact becomes a Mailchimp subscriber. Email address is the unique identifier — duplicates by email are merged. First name, last name, phone, and address map to standard Mailchimp fields. Owner assignment from Eagle CRM is stored in a merge field since Mailchimp has no owner concept.
Eagle CRM
Company
Mailchimp
Merge field (COMPANY) or Tag
1:1Eagle CRM company name maps to Mailchimp COMPANY merge field. If a contact is associated with multiple companies in Eagle CRM, the primary company (most-recently-linked) is stored in the merge field and secondary associations are added as tags in the format 'company: [name]'.
Eagle CRM
Deal / Pipeline Stage
Mailchimp
Segment or Tag
1:1Eagle CRM deals and pipeline stages have no direct Mailchimp equivalent. We export deal stage values as tags (e.g., 'pipeline_stage: Active Prospect') for segmentation in Mailchimp, but the transactional nature of deals does not translate — that logic must be rebuilt in Mailchimp automations or handled outside the platform.
Eagle CRM
Contract
Mailchimp
Custom Merge Field or Tag
1:1Contract records in Eagle CRM contain terms, dates, and statuses with no Mailchimp counterpart. We migrate contract status as a tag (e.g., 'contract_status: Active') and store contract ID in a merge field for reference, but the full contract object must be maintained in a document management system or rebuilt in a dedicated tool.
Eagle CRM
Note
Mailchimp
Note on Subscriber or Tag
1:1Eagle CRM notes attached to contacts are added as Mailchimp notes on the subscriber profile (up to 255 characters per note). Notes exceeding that limit are stored as tags with a truncated prefix. Original note timestamps and owner attribution are preserved in the note body.
Eagle CRM
Activity (Call / Email / Meeting)
Mailchimp
Activity Tag or Ignored
1:1Call logs, email history, and meeting records in Eagle CRM have no Mailchimp equivalent — Mailchimp tracks opens, clicks, and unsubscribes only. We export activity counts as tags (e.g., 'call_count: 3') and flag the full activity log for export as a CSV that your team can reference alongside Mailchimp reporting.
Eagle CRM
Custom Property (Contact)
Mailchimp
Merge Field
1:1Eagle CRM custom properties on contacts (e.g., 'Lead Source', 'Preferred Neighborhood', 'Agent Rating') are created as Mailchimp merge fields in the target Audience. Merge field type (text, number, date, dropdown) is inferred from the source data type. Mailchimp allows up to 40 merge fields per Audience — we flag any overflow for prioritization.
Eagle CRM
Custom Property (Company)
Mailchimp
Merge Field or Tag
1:1Company-level custom properties in Eagle CRM (e.g., 'Listing Status', 'Property Type') are mapped to merge fields or tags on the associated contact's Mailchimp profile depending on cardinality. Single-value properties become merge fields; multi-value or list-type properties become tag sets. When a company has multiple agents or listing types, each value becomes a separate tag on the primary contact's subscriber profile.
Eagle CRM
Owner / User
Mailchimp
Merge Field or Tag
1:1Eagle CRM owner assigned to a contact maps to a merge field (OWNER_EMAIL or OWNER_NAME) in Mailchimp. This preserves accountability without assigning Mailchimp roles — your team uses this field for internal routing or to trigger owner-specific automations. Owner tags can also be applied if your team prefers tag-based filtering over merge field queries.
Eagle CRM
Tag / Label (Eagle CRM)
Mailchimp
Mailchimp Tag
1:1Tags applied to contacts in Eagle CRM are migrated as Mailchimp tags on the corresponding subscriber. Tag names are preserved as-is. This is the most reliable 1:1 mapping in the migration since both platforms use tag-based labeling. Tag counts and usage frequency are reported in the pre-migration audit.
Eagle CRM
Attachment / File
Mailchimp
Not Migrated
1:1File attachments on Eagle CRM records (listings, contracts, photos) do not migrate to Mailchimp — Mailchimp is not a document repository. We export a list of attachment URLs and file names as a CSV reference so your team can relocate assets to a document management tool.
Eagle CRM
Workflow / Automation
Mailchimp
Not Migrated
1:1Eagle CRM workflows, sequences, and automated lead-routing rules do not migrate. We export workflow definitions as a JSON reference document for your Mailchimp admin to rebuild equivalent automations in Mailchimp's customer journey builder. Trigger conditions, action sequences, and time delays are preserved in the export.

Migration approach
Audit Eagle CRM data inventory and scope merge field requirements
We connect to Eagle CRM via API to enumerate all object types, custom properties, and tag sets. We generate a data inventory report showing record counts per object, unique custom property names and data types, and tag cardinality. This report drives the merge field prioritization discussion if your Eagle CRM setup exceeds Mailchimp's 40-merge-field limit per Audience. The audit also identifies any contacts missing email addresses, which are flagged for exclusion from the subscriber migration pending your review.
Create Mailchimp Audience and configure merge fields before data lands
We provision the target Mailchimp Audience and create all required merge fields in advance using Mailchimp's API. Merge field types (text, number, date, dropdown) are set based on Eagle CRM data type inference. We coordinate with your Mailchimp admin to ensure field names and labels match your team's conventions before the migration run begins. Any merge fields that would exceed the 40-field limit are flagged for prioritization during this step.
Resolve contact-to-company relationships and owner mapping
Eagle CRM contact-to-company associations are resolved to a primary company per contact using most-recently-linked as the default rule or your specified priority logic. Owner email and name are extracted and mapped to dedicated merge fields. Secondary company associations are converted to tags in the format 'company: [name]'. Any contacts without a valid email address are flagged and excluded from the subscriber migration pending your review. This step ensures all contact records are normalized before the migration run.
Run sample migration with field-level diff across 100–500 records
A representative slice of Eagle CRM contacts migrates to Mailchimp first — we validate that merge fields populate correctly, tags apply as expected, and subscriber count matches the source query. We generate a field-level diff report so you can verify mapping accuracy before the full run commits. Any mapping corrections are applied before proceeding. The sample run also validates API connection stability and identifies any unexpected data quality issues early in the process.
Execute full migration with delta-pickup window and rollback plan
The full Eagle CRM contact base migrates to Mailchimp. A delta-pickup window (typically 24–48 hours) captures any contacts or tag changes made in Eagle CRM during the cutover. All operations are logged to an audit trail. One-click rollback reverts the Audience to pre-migration state if reconciliation uncovers unexpected data quality issues. After the delta window closes, you can pause the Eagle CRM sync knowing your Mailchimp Audience reflects the final state of your contact data.
