Overview

What this migration involves

Field2Base is a field service automation platform built around mobile form design, submission capture, and workflow approval. Its data model centers on Form Templates, Form Submissions, and Submitting Users — with custom Regions as configurable form fields. Mailchimp operates as an email marketing platform with Audiences, Contacts, Merge Fields, Tags, and Campaigns. The two platforms serve fundamentally different functions, which means the migration centers on extracting submitter contact data from Field2Base submissions and reconstructing it as Mailchimp contacts with appropriate merge field values. We map Form Submissions to Contact records, Field2Base Users to Mailchimp Contacts, and custom form Regions to Mailchimp Merge Fields. Field2Base workflows (review and approval steps) have no Mailchimp equivalent — those must be rebuilt as manual processes or documented for rebuild in a separate workflow tool. Photo attachments, signatures, and barcode data cannot live in Mailchimp contacts and are exported as files for separate handling. The migration runs via Field2Base API export and Mailchimp bulk import, with a test sample validating field mapping before the full run commits.

Field2Base

What's pushing teams away

  • Small teams find the pricing model expensive at scale — Essentials starts at $20 per license per month and higher tiers require custom quotes, making per-seat costs unpredictable as the field workforce grows.
  • The platform lacks a robust self-service review ecosystem — Capterra and G2 show fewer than 15 verified reviews, which makes independent evaluation difficult and signals a narrow customer base.
  • Annual manual app update requirements were a documented pain point before Field2Base moved to app-store distribution, reflecting a historical gap in automated delivery infrastructure.
  • Companies requiring modern analytics dashboards or real-time field reporting find Field2Base's reporting layer less mature compared to newer field service platforms like UpKeep or MaintainX that embed BI tooling natively.

Choosing

Mailchimp logo

Mailchimp

What's pulling them in

  • Generous free tier with up to 500 contacts allows small teams to validate email marketing before committing to a paid plan.
  • Intuitive drag-and-drop email builder and 130+ templates let non-technical users produce professional campaigns without HTML or CSS knowledge.
  • 300+ native integrations, especially Canva and Shopify, make it easy to connect existing tools without custom development work.
  • Detailed open-rate, click-through, and campaign analytics give small businesses actionable insights without a dedicated marketing team.
  • One-platform consolidation of email campaigns, automations, landing pages, and ads reduces tool sprawl for lean marketing teams.

Object mapping

How Field2Base objects map to Mailchimp

Each row shows how a Field2Base 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.

Field2Base

Form Submission

maps to

Mailchimp

Contact

1:1
Fully supported

Each Field2Base Form Submission maps to one Mailchimp Contact. The submitter's email address becomes the Contact's email address, which serves as Mailchimp's primary identifier. Multiple submissions from the same email address update the existing Contact rather than creating duplicates. This mapping also supports future updates where new submissions automatically refresh the corresponding contact's data in Mailchimp.

Field2Base

Submitting User

maps to

Mailchimp

Contact

1:1
Fully supported

Field2Base User accounts with email addresses map directly to Mailchimp Contacts. Users without email addresses cannot become Mailchimp contacts — those are flagged for manual review. User role (Admin, Form Designer, Mobile User) maps to Tags on the Mailchimp Contact.

Field2Base

Form Template

maps to

Mailchimp

Audience + Tag Group

many:1
Fully supported

If migrating multiple form types, each Form Template maps to a dedicated Tag in Mailchimp applied to all Contacts created from submissions of that template. Alternatively, all submissions consolidate into one Mailchimp Audience with a form-type merge field identifying the source template.

Field2Base

Region (custom form field)

maps to

Mailchimp

Merge Field

1:1
Fully supported

Each Field2Base Region (text, numeric, date, dropdown, checkbox) on a Form Template maps to a Mailchimp Merge Field. Field2Base field validation rules inform the merge field data type. Dropdown Regions require value-by-value mapping to Mailchimp pick-list options. We also generate a validation report highlighting any values that do not map directly.

Field2Base

Submission Timestamp

maps to

Mailchimp

Merge Field (SubmissionDate)

1:1
Fully supported

Mailchimp Contacts have no native submission timestamp. We create a F2B_SUBMIT_DATE merge field capturing the original Field2Base submission datetime. This preserves historical submission ordering for marketing segmentation. This timestamp can later be used in Mailchimp date‑based automations to trigger follow‑up emails based on when the original form was filled out.

Field2Base

Approval Status

maps to

Mailchimp

Merge Field (ApprovalStatus) + Tag

1:1
Fully supported

Field2Base workflow approval status (Pending, Approved, Rejected) migrates as a merge field and applies corresponding Tags in Mailchimp. Approval routing logic cannot transfer — it becomes a documented reference for manual process rebuild. These tags enable segmentation by approval outcome, allowing targeted email campaigns for approved or pending items.

Field2Base

GPS Location

maps to

Mailchimp

Merge Field (SubmissionLocation)

1:1
Fully supported

Field2Base GPS coordinates captured at submission migrate as latitude/longitude text in a F2B_GPS merge field. Geolocation segmentation in Mailchimp requires additional tools like Mailchimp's built-in location filtering on the city or country level. Mailchimp's location filters can then be applied to these coordinates for basic geographic segmentation across campaigns.

Field2Base

Photo Attachment

maps to

Mailchimp

External File Export

1:1
Fully supported

Photos captured via Field2Base Camera Region cannot attach to Mailchimp contacts. We export all photos to a cloud storage location and create a F2B_PHOTOS_URL merge field storing the link reference. Photos must be hosted externally. All URLs are validated for accessibility before the final import to prevent broken links.

Field2Base

Signature

maps to

Mailchimp

External File Export

1:1
Fully supported

Signature images captured on Field2Base forms have no Mailchimp equivalent. Signatures are exported as image files with the corresponding contact email in the filename for manual association. A F2B_SIGNATURE_URL merge field links to the exported file. The filename includes the submission ID for quick lookup when needed.

Field2Base

Form Workflow

maps to

Mailchimp

Customer Journey (manual rebuild reference)

1:1
Fully supported

Field2Base workflows with multi-step approval chains have no direct Mailchimp equivalent. We document the workflow structure, approval steps, and conditional logic as a reference guide for rebuilding in Mailchimp Customer Journeys or a separate workflow tool. This documentation can be shared with stakeholders to align on process redesign before implementation.

Field2Base

Barcode / QR Data

maps to

Mailchimp

Merge Field (BarcodeValue)

1:1
Fully supported

Barcodes and QR codes scanned via Field2Base migrate as text in a F2B_BARCODE merge field. The barcode image itself is not preserved — only the decoded data value. Barcode lookup or validation logic is not transferred. If a barcode is invalid, we log the raw value for manual review rather than skipping the contact.

Field2Base

Offline Submission Flag

maps to

Mailchimp

Merge Field (OfflineCaptured)

1:1
Fully supported

Submissions captured offline before syncing carry a flag in Field2Base. We preserve this as a F2B_OFFLINE merge field with Yes/No values so marketing can filter for contacts captured in offline-first scenarios. This field can be used in Mailchimp segment filters to target users who submitted forms while offline, enabling follow‑up on connectivity issues.

Pair-specific challenges

  • Photo and signature data have no Mailchimp home

    Field2Base Camera and Signature Regions capture rich binary data including inspection photos, delivery confirmations, and signed acceptance documents. Mailchimp contacts store only text-based merge fields — binary attachments are not supported. FlitStack AI exports all photos and signatures to cloud storage (S3 bucket or equivalent), then populates a URL merge field on each contact referencing the exported file. The files exist independently of Mailchimp and must be maintained separately. Marketing teams using these for proof-of-service or compliance documentation should plan for an external document management strategy post-migration.

  • Merge field count limits constrain large-form migrations

    Mailchimp imposes a limit on merge fields per audience — approximately 40 merge field types available by default, with additional fields available on higher tiers. Field2Base Form Templates with 20+ custom Regions (common in detailed inspection forms or compliance checklists) can exceed this limit. FlitStack AI surfaces this before migration by auditing all Regions across source Form Templates. High-volume Regions are prioritized; low-value Regions are mapped to Tags or flagged for consolidation. If the limit is reached, contacts can be split across multiple Mailchimp audiences, each representing a form type subset.

  • Dropdown value-by-value mapping required for each pick-list

    Field2Base Dropdown Regions allow unlimited custom option values configured per Form Template. Mailchimp merge fields of type dropdown require options to be predefined in the audience settings. When a Field2Base dropdown contains values not present in Mailchimp's corresponding merge field options, those contacts fail import until the mismatch is resolved. FlitStack AI generates a complete dropdown value audit comparing Field2Base options against Mailchimp merge field options before migration. Unmapped values are either added to Mailchimp (if the account permissions allow) or mapped to a catch-all 'Other' value with a flag for manual review.

  • Field2Base workflows do not translate to Mailchimp Customer Journeys

    Field2Base Workflows implement multi-step approval chains where submitted forms route to reviewers for edit, approve, or reject actions. Mailchimp Customer Journeys are email automation builders triggered by contact behavior — fundamentally different from document approval workflows. There is no automated way to reconstruct Field2Base approval chains in Mailchimp. FlitStack AI exports the complete workflow definition including step order, approver assignments, conditional routing, and deadline settings as a documented reference. Teams use this to manually rebuild the logic in Mailchimp Customer Journeys (for email-based approvals) or a dedicated workflow tool.

  • Offline submission tracking does not replicate in Mailchimp

    Field2Base Mobile Forms work offline — field crews capture submissions without internet connectivity, and the app syncs when a connection returns. The sync timestamp can differ from the original submission timestamp by hours or days. Mailchimp has no native mechanism to represent this offline-then-sync pattern. FlitStack AI captures both timestamps (submission_at and synced_at) as separate merge fields, but Mailchimp's segmentation and time-based automations operate on contact creation time, not these historical event times. Teams relying on Field2Base's offline capture for compliance or proof-of-timing documentation should be aware that Mailchimp automation triggers will use import time, not field-capture time.

Migration approach

Six steps for a successful Field2Base to Mailchimp data migration

  1. Audit Form Templates and Region configurations

    FlitStack AI connects to the Field2Base API and enumerates all Form Templates, custom Regions, and data types configured in the account. We identify dropdown value lists, required field constraints, and any Regions that may exceed Mailchimp merge field limits. This audit produces a Region-to-MergeField mapping spreadsheet that serves as the migration specification before any data moves. The resulting spreadsheet also flags any Regions that cannot be mapped due to type mismatches, allowing the team to decide whether to adjust the Field2Base template or use a workaround such as storing data in tags.

  2. Configure Mailchimp audience and merge fields

    Using the mapping spreadsheet from the audit, FlitStack AI creates the required merge fields in the target Mailchimp audience — including all custom field names, data types, and dropdown options pulled from Field2Base. If merge field limits are reached, we coordinate with the team to either split across multiple audiences or consolidate low-priority Regions into Tags. SPF, DKIM, and domain authentication are verified to protect email deliverability post-migration.

  3. Extract submitter data and form submissions via API

    FlitStack AI pulls all Form Submissions and Submitting User records from Field2Base via the REST API. For each submission, we extract the submitter profile, all Region field values, GPS coordinates, approval status, submission timestamp, and device type. Photos and signatures are downloaded to cloud storage separately. The extraction preserves the original Field2Base submission IDs for traceability. The export also records the device model and operating system when available, providing insight into the mobile environment where submissions originated.

  4. Run test migration on sample submission slice

    A representative sample — typically 100–500 submissions spanning multiple Form Templates and approval statuses — imports into the Mailchimp audience first. FlitStack AI generates a field-level diff comparing source Field2Base values against the resulting Mailchimp contact merge field values. The team reviews dropdown value mapping accuracy, URL references for photos and signatures, and tag application before the full run commits.

  5. Execute full migration with delta pickup window

    The complete dataset imports into Mailchimp. A delta pickup window (typically 24–48 hours) captures any new Field2Base submissions created during the migration window. FlitStack AI applies Tags for Form Template, user role, and approval status. An audit log records every operation, and one-click rollback is available if the team identifies data integrity issues requiring a restart. Should any validation errors arise during import, FlitStack AI logs them with field‑level detail so the team can correct source data and re‑run the affected batch without restarting the entire migration.

  6. Deliver workflow documentation and external file package

    FlitStack AI exports all photos, signatures, and barcode images to a structured cloud storage folder (organized by submitter email and submission ID). A manifest CSV maps each Mailchimp contact email to its corresponding file paths. We deliver the complete Field2Base Workflow definition as a documented reference for manual rebuild in Mailchimp Customer Journeys or a separate tool. All exported files are organized in a nested folder structure that mirrors the original Field2Base submission hierarchy for straightforward retrieval.
