Overview
SimplyConvert stores law-firm data as contacts (with name, email, phone, address), cases (with status, type, intake source, case criteria in JSON), referral sources, and firm-level custom fields. The platform charges per qualified client conversation, not per contact, which means a high volume of intake leads may sit in the CRM without triggering billing. Mailchimp structures everything as an audience — contacts plus merge fields (custom properties) and tags for segmentation. The migration pulls every contact and every case record via the SimplyConvert API, then writes them into Mailchimp as subscriber records with merge fields derived from case fields and tags derived from intake source and referral information. Case files and documents (PDFs, evidence uploads) do not migrate because Mailchimp has no document storage — those assets must remain in SimplyConvert or a separate document management system. The migration uses API extraction with a 300 requests per minute rate limit on the List Cases endpoint, and bulk import into Mailchimp audiences. Automations and intake chatbot logic in SimplyConvert do not transfer — those rebuild as Mailchimp Customer Journeys.

Object mapping
Each row shows how a SimplyConvert 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.
SimplyConvert
Contact
Mailchimp
Subscriber
1:1Every SimplyConvert contact maps to one Mailchimp subscriber in the target audience. Email address serves as the primary match key for deduplication. If multiple SimplyConvert records share the same email, the first record imported takes precedence and subsequent duplicates are logged for your team to resolve. Unsubscribed contacts in SimplyConvert migrate as unsubscribed in Mailchimp to preserve suppression lists and prevent re‑activation.
SimplyConvert
Contact.firstname / lastname
Mailchimp
FNAME / LNAME merge field
1:1SimplyConvert stores first name and last name as separate fields on the contact record. These map directly to Mailchimp's built‑in FNAME and LNAME merge fields, which are present in every audience by default — no custom merge field creation is required. If a contact lacks a name component, the respective merge field remains blank while the subscriber record is still imported.
SimplyConvert
Contact.email
Mailchimp
EMAIL address (subscriber identity)
1:1Email address is the primary key in Mailchimp, so each subscriber must have a unique email value. We use the SimplyConvert contact email as the subscriber identifier, passing it to the Mailchimp API during import. If multiple SimplyConvert contacts share the same email, the first record imported becomes the subscriber and subsequent duplicates are logged for your team to review and resolve. This prevents duplicate subscribers and maintains data integrity.
SimplyConvert
Contact.phone
Mailchimp
PHONE merge field
1:1Phone number maps to the PHONE merge field. If your Mailchimp plan supports phone number collection, we create the PHONE merge field during import. Because SimplyConvert stores phone numbers as free‑text, formatting can vary (with or without country codes, dashes, parentheses, etc.). Imported phone numbers are flagged for formatting review so your team can verify them before using in SMS campaigns or call‑tracking integrations.
SimplyConvert
Contact.address fields
Mailchimp
ADDR1 / CITY / STATE / ZIP / COUNTRY merge fields
1:1SimplyConvert stores address components broken into street, city, state, and postal code. These map to Mailchimp's five address merge fields, which enable geolocation‑based segmentation and targeted campaigns. If a contact lacks a specific component, the corresponding merge field is left blank while the remaining fields are imported. This preserves all available address data and lets your team build location‑based segments without requiring a complete address for every subscriber.
SimplyConvert
Case (linked to Contact)
Mailchimp
Merge fields on subscriber record
1:1Each active SimplyConvert case linked to a contact generates one row of merge field values on the corresponding Mailchimp subscriber. Case fields like status, type, intake source, and firm-specific criteria become named merge fields in Mailchimp. Multiple cases per contact generate multiple merge field sets — we apply the most recent case values.
SimplyConvert
Case.case_status
Mailchimp
CASESTATUS merge field (custom TEXT)
1:1SimplyConvert case statuses (New, Screening, Qualified, Signed, Rejected) map to a CASESTATUS merge field in Mailchimp. Each status value is written as the merge field value for the subscriber. Mailchimp segments can then filter by case status for targeted campaigns.
SimplyConvert
Case.case_type
Mailchimp
CASETYPE merge field (custom TEXT)
1:1Case type (e.g., Personal Injury, Mass Tort, Employment) is written to a CASETYPE merge field on each subscriber. This mapping lets you filter contacts by case type within Mailchimp, so you can send newsletters, legal updates, or practice‑area announcements to the relevant audience. By preserving case type as a merge field, you avoid manually recreating audience segments and can dynamically target groups based on the case categories stored in SimplyConvert.
SimplyConvert
Case.intake_source / referred_by
Mailchimp
Mailchimp Tags
1:1Intake source (Organic, Paid Ad, Referral Partner) and referred_by values from SimplyConvert are translated into Mailchimp tags on each subscriber. If a contact has multiple referral sources, each source receives its own tag, resulting in multiple tags per subscriber. These tags allow you to create Mailchimp segments that isolate contacts by their origin, run partner‑specific thank‑you sequences, and track the effectiveness of each acquisition channel over time.
SimplyConvert
Case (case criteria JSON fields)
Mailchimp
Custom merge fields per unique field name
1:1SimplyConvert stores case criteria as dynamic JSON (accident date, injury type, policy limits, etc.) that varies by case type. We extract every unique field name across all cases and create a corresponding Mailchimp merge field per unique name. Fields exceeding 255 characters are truncated with a note in the migration log.
SimplyConvert
Case.case_value / estimated_value
Mailchimp
CASEVALUE merge field (custom NUMBER)
1:1Case estimated value in SimplyConvert maps to a CASEVALUE merge field of type number. Mailchimp’s number merge fields allow you to perform comparative segmentation, such as filtering contacts whose case value exceeds a threshold (e.g., $100k) or sorting subscribers by projected case value. This enables targeted outreach to high‑value prospects, case‑status reports by value tier, and more accurate pipeline reporting within Mailchimp.
SimplyConvert
Contact.hs_lead_score (if present)
Mailchimp
LEADSCORE merge field (custom NUMBER)
1:1If your SimplyConvert CRM includes a lead scoring property, it migrates as a LEADSCORE merge field. Mailchimp does not have native lead scoring — this value serves as a reference attribute for segment filtering rather than an active scoring mechanism.
SimplyConvert
Contact / Case created_date
Mailchimp
INTAKEDATE merge field (custom DATE)
1:1SimplyConvert records created timestamps map to an INTAKEDATE merge field. Mailchimp's DATE merge field type accepts ISO-format dates. Original intake date enables time-based segments (e.g., contacts who signed up in the last 30 days) without rebuilding the timeline in Mailchimp.
SimplyConvert
Contact.hs_object_id (SimplyConvert record ID)
Mailchimp
SRC_RECORD_ID merge field (custom TEXT)
1:1The SimplyConvert internal record ID is stored as a custom SRC_RECORD_ID merge field on each Mailchimp subscriber. This ID serves as a stable anchor for delta re‑sync runs, allowing FlitStack to import only records that have changed since the last migration. It also enables your team to cross‑reference Mailchimp subscriber data with the original SimplyConvert case record for reconciliation, audit trails, or to trigger downstream updates in other systems.
SimplyConvert
Contact.firm_user_id (assigned attorney or intake rep)
Mailchimp
ASSIGNED_TO merge field (custom TEXT)
1:1The SimplyConvert user ID or name assigned to the contact/case is written to an ASSIGNED_TO merge field on the Mailchimp subscriber. This mapping preserves internal accountability by linking each contact to its responsible attorney or intake representative. You can then create Mailchimp segments that filter contacts by the assigned user, enabling attorney‑specific drip campaigns, performance dashboards, and case‑load reporting directly within Mailchimp.
SimplyConvert
Case files and document attachments
Mailchimp
No equivalent in Mailchimp
1:1SimplyConvert stores PDF documents, evidence uploads, and intake form files attached to case records. Mailchimp has no document attachment or file storage feature. These assets cannot migrate. We recommend exporting document metadata (file name, upload date, owner) as a CASE_DOCS reference field and retaining the original files in SimplyConvert.
SimplyConvert
SimplyConvert intake chatbot flows
Mailchimp
Mailchimp Customer Journeys
1:1The SimplyConvert Instant Case Evaluator chatbot and its branching logic, qualification criteria, and automated retention rules do not have a direct equivalent in Mailchimp. These automations must be rebuilt as Mailchimp Customer Journeys. We export a plain-text description of each chatbot flow for your Mailchimp admin to reference during rebuild.
SimplyConvert
SimplyConvert referral platform records
Mailchimp
Mailchimp Tags + REFERRAL_SOURCE merge field
1:1Referral partner records (partner name, fee agreement, referred case count) from SimplyConvert's referral module map to a REFERRAL_SOURCE merge field and a REFERRAL_TAG on each referred contact. This preserves partner attribution data without duplicating every referral partner as a separate Mailchimp audience.
SimplyConvert
SimplyConvert reporting dashboard configurations
Mailchimp
Mailchimp Analytics reports
1:1SimplyConvert's custom reporting dashboards (case volume by source, conversion rates by intake channel) are configuration-based and do not export as data. Underlying contact and case data migrates, but the specific chart layouts, date ranges, and dashboard filters must be rebuilt in Mailchimp Analytics.

Pair-specific challenges
Migration approach
Connect to SimplyConvert API and audit contact + case schema
FlitStack authenticates to the SimplyConvert API using your account API key from the Integration Settings page. We run a schema discovery pass that inventories all contact fields, all case fields, and the structure of the case criteria JSON across every case type in your account. This pass also counts total contacts, cases, referral records, and custom field instances. The output is a schema map that drives every subsequent mapping decision — particularly the merge field creation plan for Mailchimp.
Plan Mailchimp merge fields and audience structure
Based on the schema discovery, FlitStack generates a merge field creation plan for your Mailchimp account. For each unique field name in the SimplyConvert contact or case criteria JSON, we specify the merge field name, type (TEXT, NUMBER, DATE, ADDRESS), and whether it should be required. If you run multiple case types, we recommend either one unified audience with case-type-specific merge fields (some blank per contact) or one audience per case type — your team chooses the structure before migration commits.
Migrate contacts and cases with field-level transformation
Contacts export via the SimplyConvert API at the rate limit of 300 requests per minute on List Cases. For each contact, we pull linked case records and extract the case criteria JSON into individual merge field values. Referral source and referred_by fields become Mailchimp tags. Unsubscribed contacts from SimplyConvert are imported as unsubscribed in Mailchimp to preserve suppression lists. A field-level diff is generated comparing source field values to destination merge field values — you review this before the full run commits.
Run a sample migration with field-level diff
A representative slice of 100–500 records migrates first — spanning multiple case types, referral sources, and case statuses. We generate a field-level diff between the SimplyConvert source values and the Mailchimp subscriber merge fields so you can verify case status mapping, referral tag assignment, date formatting, and the 255-character truncation handling before the full run. Any mapping adjustments are applied to the full run configuration.
Full migration with delta-pickup and audit log
The full migration runs against your Mailchimp audience. A delta-pickup window (typically 24–48 hours) captures any new contacts or case record updates that occurred in SimplyConvert during the cutover window. FlitStack provides a complete audit log of every record written, every merge field set, and every tag applied. If reconciliation reveals gaps, one-click rollback reverts the Mailchimp audience to its pre-migration state. Case files and chatbot logic are documented separately as non-migratable assets.
