Overview
Forms On Fire stores form submissions as entries: each entry contains submitter contact data (email, name, phone) plus field-by-field response data captured by the form's custom field schema. Forms On Fire supports a wide range of field types — text, number, date, location (GPS), photo, signature, barcode, and more — all tied to a specific form definition that lives inside the Forms On Fire platform. Mailchimp organizes data around a single Audience (or multiple audiences) of contacts. Each contact holds standard fields (email, first name, last name, phone, address) and arbitrary merge fields for custom data. Tags and groups provide segmentation; there is no native equivalent of form entries or field-operations submissions. FlitStack extracts every Forms On Fire entry with an email address and maps each contact field to Mailchimp's standard contact fields. Custom field responses map to Mailchimp merge fields — created in your Mailchimp audience before import — preserving the original field type semantics where Mailchimp supports them. Submission timestamps, form-of-origin identifiers, and GPS coordinates become Mailchimp merge fields. File attachments and photos require re-upload to Mailchimp's file manager. Form definitions, conditional logic, workflow routing rules, and automated alerts do not have Mailchimp equivalents and must be rebuilt using Mailchimp's form builder and automation tools.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Forms On Fire 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.
Forms On Fire
Form Entry
Mailchimp
Contact (Mailchimp Audience)
1:1Every Forms On Fire entry with an email address maps to one Mailchimp contact in the target audience. Entries without an email address are flagged as non-importable and reported in the pre-migration audit — those records require manual outreach or an email-capture step before import.
Forms On Fire
Form Entry (Submitter Data Fields)
Mailchimp
Contact Standard Fields (Email, First Name, Last Name, Phone, Address)
1:1Forms On Fire's built-in submitter contact fields — typically Email, Name, Phone, and Address — map directly to Mailchimp's standard contact fields using field-name matching. If your form captures these fields with custom data names (e.g., submitter_email instead of email), FlitStack resolves the mapping from the form schema.
Forms On Fire
Custom Field (Text, Number, Date, Dropdown)
Mailchimp
Merge Field (Mailchimp Audience)
1:1Each unique custom field in a Forms On Fire form maps to a Mailchimp merge field. Text fields become merge fields of type text; number fields become merge fields of type number; date fields become merge fields of type date. FlitStack creates the merge fields in your Mailchimp audience before the import run so the import schema is complete.
Forms On Fire
Custom Field (GPS Location)
Mailchimp
Merge Field (Text — Address components)
1:1Forms On Fire's GPS location field captures latitude, longitude, and optionally a named address. Mailchimp has no native GPS field type. FlitStack parses the GPS object and populates Mailchimp's structured address fields (addr1, city, state, zip, country) when an address string is available, or writes raw lat/long as a text merge field when only coordinates exist.
Forms On Fire
Custom Field (Photo, Signature, File Upload)
Mailchimp
Mailchimp File Manager + Merge Field (Image or Text URL)
1:1Forms On Fire stores binary file attachments (photos, signatures, PDFs) in its document management system. Mailchimp has a file manager for images but no native attachment field. FlitStack downloads each attachment, uploads it to your Mailchimp account's file manager, and stores the resulting URL in a text or image-type merge field on the contact record. Large files may require manual re-upload if they exceed Mailchimp's file size limits.
Forms On Fire
Form Definition (Form Name + Field Schema)
Mailchimp
Tags + Merge Field (Form_of_Origin__c)
1:1The form definition — field names, field types, conditional logic, and layout — lives inside Forms On Fire's form builder and has no direct Mailchimp equivalent. FlitStack preserves form-of-origin by tagging each contact with the source form name and populating a Form_of_Origin__c merge field. The form itself must be rebuilt as a Mailchimp signup form using Mailchimp's form builder.
Forms On Fire
Entry Submission Timestamp
Mailchimp
Merge Field (Date — Submission_Date__c)
1:1Forms On Fire records the exact submission timestamp for each entry. Mailchimp contacts have no native submission-date field. FlitStack creates a Submission_Date__c merge field of type date and populates it with the original Forms On Fire entry creation timestamp, preserving historical submission timing for segmentation and reporting in Mailchimp.
Forms On Fire
Custom Field (Barcode, QR Code, Calculation Result)
Mailchimp
Merge Field (Text)
1:1Forms On Fire field types with no Mailchimp equivalent — barcode scan values, QR code data, and calculated field results — map to text-type merge fields. The string representation of the value is preserved; the barcode image itself is not transferable and must be regenerated in the destination workflow if needed.
Forms On Fire
Multiple Entries (Same Email, Multiple Forms)
Mailchimp
Single Contact + Cumulative Tags
many:1A single person may have submitted entries via multiple Forms On Fire forms. Mailchimp contacts are one-per-email-address — FlitStack merges these into a single contact record and applies tags for each unique form-of-origin. Merge fields from the most recent entry overwrite prior values unless you specify a 'latest wins' or 'preserve all' strategy at the project scoping stage.
Forms On Fire
Forms On Fire User / Owner
Mailchimp
Mailchimp Tags or Merge Field (Last_Submitted_By__c)
1:1Forms On Fire tracks which user submitted or owned an entry. Mailchimp contacts have no native owner field. FlitStack can surface the submitter as a text merge field (Last_Submitted_By__c) or apply a tag for reporting, but owner-based routing or permissions in Mailchimp require a separate administrative setup.

Migration approach
Audit Forms On Fire forms and entry volumes
FlitStack connects to Forms On Fire via API using scoped read access and inventories every form definition and entry in your account. We count unique contact records, identify custom field types across all forms, flag entries without email addresses, and estimate merge field creation requirements per Mailchimp audience. This audit produces a migration scope document that lists every field that will map, every field that needs a custom merge field, and every entry that cannot import without an email address.
Design Mailchimp merge field schema in your audience
Before any data moves, FlitStack generates a merge field creation plan for your Mailchimp audience. For each unique Forms On Fire custom field name, we specify the Mailchimp merge field name (following Mailchimp's NAME format: uppercase, no spaces), the field type to use, and any value-mapping requirements for dropdown fields. You approve the schema — or your Mailchimp admin creates the merge fields manually using our plan — before the import run begins. This step prevents import errors from missing merge fields.
Clean and deduplicate the contact list
Forms On Fire exports may contain duplicate emails across multiple form submissions, outdated email addresses, or formatting inconsistencies (extra spaces, case differences). FlitStack normalizes email addresses, applies your chosen deduplication strategy (latest entry wins, or first entry wins), and flags hard bounces and invalid formats before the Mailchimp import. Contacts flagged as non-importable are listed in the pre-migration report so your team can decide how to handle them separately.
Run a sample migration with field-level verification
A representative slice — typically 100–500 contact records spanning your most common Forms On Fire forms — imports first into your Mailchimp audience. FlitStack generates a field-level diff report showing every source field and its mapped Mailchimp value. You verify that standard fields mapped correctly, merge fields populated as expected, and form-of-origin tags were applied. GPS fields, photo fields, and any transformed fields are spot-checked individually. No full run commits until you sign off on the sample.
Execute full migration with delta pickup and audit log
The full Forms On Fire contact set — all entries with valid email addresses — imports into Mailchimp via the Marketing API. A delta-pickup window (24–48 hours) captures any new entries created in Forms On Fire during the cutover period. FlitStack logs every operation: contact created, merge field populated, tag applied, attachment re-uploaded. If reconciliation detects missing records or field-value mismatches, one-click rollback reverts the Mailchimp audience to its pre-migration state while your team reviews the issue.
