Overview
FieldPros stores recruiting relationships as candidate profiles, client company records, and placement history tied to a talent-acquisition workflow. Mailchimp models its universe as contacts within audiences, tagged and segmented by any custom property you define. The migration maps FieldPros candidates and client contacts to Mailchimp contacts, preserves recruiting-specific fields (candidate tier, placement status, open reqs, source channel) as Mailchimp merge fields, and translates FieldPros pipeline stages into Mailchimp tags and audience segments. Mailchimp has no native candidate-management or applicant-tracking model — your recruiting workflows and job req boards must be rebuilt in a dedicated ATS. FlitStack AI uses Mailchimp's API for contact ingestion and bulk import for large record sets, preserving original create dates as merge-field metadata for reporting continuity. The migration also decomposes placement records into individual merge fields on the candidate contact, maintaining compensation details and start dates as reference data while applying placement status tags for immediate segmentation.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Field Pros 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.
Field Pros
Candidate
Mailchimp
Contact (Mailchimp Audience)
1:1FieldPros candidate records map 1:1 to Mailchimp contacts. Every candidate's email, name, phone, and location fields become Mailchimp standard merge fields. Candidates without an email address are flagged as partial records — they cannot be imported to Mailchimp since email is required.
Field Pros
Candidate Tier
Mailchimp
Mailchimp Tag
1:1FieldPros candidate tiers (e.g., Bronze, Silver, Gold, Platinum) become Mailchimp tags applied per contact. Tags are additive — a candidate can carry multiple tier tags if their status has changed. Mailchimp applies all tags during bulk import using the API tagging endpoint.
Field Pros
Placement Status
Mailchimp
Mailchimp Tag
1:1FieldPros placement statuses (Active, Placed, Withdrawn, On Hold) map to Mailchimp tags: 'status-active', 'status-placed', 'status-withdrawn', 'status-on-hold'. These tag values are pre-defined in the migration plan before import so Mailchimp audience segments can filter by recruitment stage immediately after data lands, enabling instant segmentation by candidate availability.
Field Pros
Skill Tags / Categories
Mailchimp
Mailchimp Tags
1:1FieldPros skill tags (e.g., 'EdTech Sales', 'Curriculum Design', 'Data Science') map directly to Mailchimp tags. These tags enable audience segmentation for targeted talent outreach campaigns — a candidate tagged 'EdTech Sales' can be included in a product launch campaign email.
Field Pros
Source Channel
Mailchimp
Mailchimp Merge Field
1:1FieldPros source channel (LinkedIn, referral, job board, event) has no native Mailchimp field. We create a text merge field (SOURCE_CHANNEL) and populate it from FieldPros during migration. This field is filterable in Mailchimp segmentation but not as performant as a tag.
Field Pros
Client Company
Mailchimp
Mailchimp Merge Field + Tag
1:1FieldPros client company records do not map to a native Mailchimp object — Mailchimp has no company/ account concept. We create a text merge field (CLIENT_COMPANY) on each candidate contact and optionally apply a tag matching the client name so segmenting by employer is possible in Mailchimp.
Field Pros
Salary Band / Rate
Mailchimp
Mailchimp Merge Field
1:1FieldPros salary band fields (hourly rate, annual salary range) migrate as number merge fields (SALARY_MIN, SALARY_MAX, RATE_TYPE). Mailchimp's standard merge fields support number types for filtering in segmentation — however, range-based filtering (e.g., candidates between $80k-$100k) requires manual segment creation in the Mailchimp UI.
Field Pros
Last Activity Date
Mailchimp
Mailchimp Merge Field
1:1FieldPros last-activity timestamp (last outreach, interview, offer date) preserves as a datetime merge field (LAST_ACTIVITY_DATE). Mailchimp does not expose activity timestamps natively for segmentation — the merge field is stored for reporting reference but cannot trigger automation logic without Mailchimp's Event API.
Field Pros
Candidate Notes / Resume
Mailchimp
Mailchimp Note Field
1:1FieldPros candidate notes migrate to Mailchimp contact notes. Resume content or file URLs are stored as a text merge field (RESUME_URL) pointing to a hosted copy — Mailchimp does not natively store file attachments on contact records, so we preserve a reference URL for manual retrieval.
Field Pros
Placement Record
Mailchimp
Mailchimp Merge Fields + Tag
many:1A FieldPros placement (candidate + client + compensation + start date) is not a native Mailchimp concept. We merge placement data across three merge fields on the candidate contact: PLACEMENT_CLIENT, PLACEMENT_SALARY, and PLACEMENT_START_DATE, plus a 'placed' tag. Historical placements are preserved as read-only reference data on each contact record.
Field Pros
Job Requisition
Mailchimp
No Equivalent
1:1FieldPros job req records (title, requirements, open/closed status) have no Mailchimp equivalent. Mailchimp is not an ATS — job req data must be exported as a reference CSV and re-entered in a dedicated applicant-tracking tool. We preserve the full job req export for manual rebuild.
Field Pros
Interview / Calendar Events
Mailchimp
No Equivalent
1:1FieldPros interview scheduling data (date, interviewer, round, outcome) has no Mailchimp construct. Mailchimp automations trigger on email opens, link clicks, or dates — not on recruiting workflow events. Interview history is exported as a CSV reference; the recruiting workflow must be rebuilt in an ATS.

Migration approach
Export FieldPros data and audit consent and completeness
FlitStack AI extracts candidate records, client records, placement history, and custom fields from FieldPros via CSV export. We run a pre-migration audit that identifies records missing email addresses (these cannot be imported to Mailchimp), records with unverifiable GDPR consent, duplicate email addresses across candidates, and records with incomplete custom fields. A data quality report is delivered before mapping begins so your team can decide whether to cleanse, skip, or archive flagged records.
Design Mailchimp audience schema and create merge fields
Based on the FieldPros data audit, FlitStack AI designs the Mailchimp audience structure: one primary talent audience, merge field definitions (SOURCE_CHANNEL, CLIENT_COMPANY, SALARY_MIN, SALARY_MAX, LAST_ACTIVITY_DATE, etc.), and a tag taxonomy for candidate tier, placement status, and skill clusters. We create all merge fields and pre-configure tags in Mailchimp before any data is ingested, so the audience is schema-ready when records land.
Build field mapping and transform placement data across objects
Every FieldPros field gets a defined mapping to a Mailchimp merge field or tag. Placement records are decomposed: client name, salary, and start date map to separate merge fields on the candidate contact, and a 'placed' tag is applied. N:N candidate-to-client associations are resolved to one primary client per contact with secondary clients exported as a reference CSV. The mapping plan is reviewed with your team before migration runs, and field-level validation rules catch out-of-range or malformed values before they enter Mailchimp.
Run sample migration with field-level diff against Mailchimp sandbox
A representative slice of 200–500 candidate records migrates to a Mailchimp test audience first. We generate a field-level diff showing each source field, its mapped Mailchimp value, and any transformation applied. You verify that merge fields populated correctly, tags applied as expected, and that candidate tier and placement status segments are filterable. We also confirm that records without email are correctly excluded and surfaced in the exclusion report.
Execute full migration with delta-pickup and GDPR re-confirmation campaign
Full record migration runs against your production Mailchimp audience. Records with unverifiable GDPR consent are routed to a 'Pending Confirmation' audience segment and triggered through a re-confirmation campaign. A 24–48 hour delta-pickup window captures any new FieldPros candidates created or modified during the migration window. Audit log records every operation, and one-click rollback is available if the import produces unexpected segmentation results.
