Overview
FilePro stores client records as part of its legal practice management system — each client record includes contact details, matter associations, billing information, and communication history. Mailchimp organizes contacts into audiences and uses merge fields for custom data, tags for categorical segmentation, and segments for dynamic filtering. The migration extracts FilePro client records through their export utilities, transforms contact fields into Mailchimp merge fields, and maps FilePro matter-type categorization onto Mailchimp tags. FilePro's proprietary database format requires conversion to standard CSV or JSON before Mailchimp import. We handle the field mapping, value transformation, and bulk import sequencing. What does not migrate: matters, billing ledgers, trust accounts, document attachments, time entries, and calendar data — these have no equivalent in Mailchimp's email-marketing model and must remain in FilePro or be reconstructed manually in Mailchimp's automation builder. Our migration workflow includes pre-flight validation of email addresses, duplicate detection, and a test import phase to confirm merge field configurations before the full load. After migration, we provide a detailed audit report and recommend a post-migration hygiene schedule to keep your Mailchimp audience up to date with ongoing FilePro updates.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a FilePro 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.
FilePro
Client Record
Mailchimp
Audience Contact
1:1Each FilePro client record becomes one Mailchimp audience contact. Email address is the required matching field for Mailchimp import — clients without emails are flagged for manual review before migration. During import, we also map the original client ID to a custom field for future reference and duplicate detection.
FilePro
Client Name (First/Last)
Mailchimp
Merge Field: FNAME / LNAME
1:1FilePro stores first name and last name as separate fields. These map directly to Mailchimp's built-in FNAME and LNAME merge fields which are available by default on every audience. If your FilePro records include middle names or suffixes, we can store them in additional custom merge fields to preserve full naming details.
FilePro
Client Email Address
Mailchimp
Email Address field
1:1The email field maps to Mailchimp's required EMAIL field. Invalid email formats are flagged during validation — malformed addresses block import of that contact record. We also run domain verification checks to ensure emails originate from active domains, reducing future bounce risk.
FilePro
Client Phone Number
Mailchimp
Merge Field: PHONE
1:1Phone numbers migrate to Mailchimp's PHONE merge field. International format preservation depends on how FilePro stores the data — we validate and reformat where necessary. We also capture the phone type (mobile, work, home) as a separate custom field if your FilePro records include that distinction.
FilePro
Client Address Fields
Mailchimp
Merge Fields: ADDRESS (city, state, zip, country)
1:1FilePro address components (street, city, state, zip, country) map to Mailchimp's compound ADDRESS merge field. The field requires specific sub-field naming — we split and reconstruct during import. If your FilePro data includes address line two or PO boxes, we map those to the appropriate ADDRESS sub-fields to preserve completeness.
FilePro
User-Defined Fields (UDF)
Mailchimp
Custom Merge Fields
1:1FilePro UDFs require Mailchimp merge field creation before import. Each UDF type (text, number, date) maps to the corresponding Mailchimp field type. Mailchimp limits 40 merge fields per audience. If your FilePro setup exceeds this limit, we prioritize the most marketing-relevant UDFs and export the remainder as a reference CSV for future use.
FilePro
Matter Type / Practice Area
Mailchimp
Mailchimp Tags
1:1Matter types linked to a client become Mailchimp tags. One client can have multiple matter types, producing multiple tags. We map each matter-type value to a corresponding tag name during migration. We also recommend consolidating similar matter types into broader practice-area tags to keep your tag list manageable as your client base grows.
FilePro
Client Status (Active/Inactive)
Mailchimp
Contact Status (Subscribed/Unsubscribed)
1:1FilePro active clients become Mailchimp subscribed contacts. Inactive clients can be imported as unsubscribed to suppress marketing emails — your team chooses the status mapping rule. If you prefer a pending status for all contacts, we can set them to pending and run a confirmation campaign after migration to re-engage them.
FilePro
Client Notes / Communication Log
Mailchimp
Mailchimp Contact Notes (limited)
1:1FilePro note entries migrate as Mailchimp contact notes — but Mailchimp notes are plain text with no formatting. Long notes exceeding Mailchimp's note length are truncated and flagged. We export the full note history to a separate CSV file so your team retains the complete communication log outside of Mailchimp.
FilePro
Matters, Documents, Invoices, Trust Accounts, Time Entries
Mailchimp
No Equivalent
1:1Legal practice data (matters, documents, billing, trust accounts, time entries) has no Mailchimp equivalent. These records remain in FilePro or your chosen legal platform. We export them as reference CSVs for manual record-keeping. These CSV files include field headers and can be imported into any accounting or document management system for long-term retention.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
FilePro gotchas
No REST API — export depends on native EXPORT utility
User Defined Fields are firm-specific with no published schema
Actionstep acquisition creates migration scope ambiguity
Document paths exported as registry, not file bodies
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Extract FilePro client records via export utilities
We access your FilePro database and run the EXPORT command against client records, producing delimited ASCII or DIF output. We also extract user-defined field definitions so we know the full schema of every custom field that needs Mailchimp merge field creation. If your FilePro setup uses multiple related tables for client data, we build a joined export query to consolidate all relevant fields into one flat record set per client.
Validate and clean email addresses against Mailchimp requirements
We run email validation against every extracted client record — checking syntax (RFC 5322), domain validity, and common typos (e.g., 'gmial.com'). Records with invalid emails are flagged in a separate review queue. We also check for duplicate email addresses across records and surface those for your team to resolve before the import. This step prevents bounce-rate surprises after migration. We also log validation results for audit purposes.
Map matter types to Mailchimp tags and create merge fields
We extract all unique matter-type values from FilePro client-matters relationships and propose a tag mapping. We also create Mailchimp merge fields for each FilePro UDF — matching the field type (text, number, date) to Mailchimp's field type constraints. We run a pre-migration test import with a sample of 50–100 records to verify the merge field configuration before committing the full dataset.
Run bulk import into Mailchimp audience with delta window
The full client contact set imports into your Mailchimp audience via CSV upload. Tags are applied per matter-type mapping during import. We apply contact status (subscribed/unsubscribed) per your chosen rule. After import, a 24-hour delta window captures any client records added or modified in FilePro during the cutover period. The audit log records every imported contact with its source FilePro ID for traceability.
Deliver reference export files for unmapped data
We export FilePro data that has no Mailchimp equivalent — matters, documents, billing ledgers, trust account balances, and time entries — as structured CSV reference files. Your team retains these for record-keeping or re-import into a different system. We also provide a migration summary report showing record counts, tag distribution, merge field coverage, and any records that failed validation with resolution notes.
