Overview
Rechat is a real estate CRM platform combining contact management, deal pipelines, MLS integration, and a marketing center with email capabilities. Mailchimp is an email marketing platform organized around audiences, subscribers, campaigns, and automations. The migration from Rechat to Mailchimp is fundamentally a data simplification: we extract Rechat contacts and their associated properties, map them into Mailchimp contacts within a target audience, and translate company affiliations into Mailchimp merge fields or tags. Rechat's deal pipeline objects, search/tour tracking, and MLS integration data have no direct Mailchimp counterpart — those records migrate as custom fields or are documented for manual rebuild. We sequence the migration to respect Mailchimp's API rate limits (10 simultaneous connections, 120‑second timeout) and field constraints (merge‑field count per plan). A delta‑pickup window captures in‑flight changes during cutover, and suppression lists (unsubscribes, bounces) from Rechat import as non‑subscribed contacts to protect deliverability. Our process also includes a pre‑migration audit to identify contacts with more properties than Mailchimp's merge‑field limit, so we can group related fields or shift data to tags before any records are written.
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 Rechat 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.
Rechat
Contact
Mailchimp
Subscriber (within Audience)
1:1Rechat contacts migrate as Mailchimp subscribers within a target audience. Email address is the unique identifier. First name, last name, phone, and job title map to standard Mailchimp merge fields (FNAME, LNAME, PHONE, TITLE). Original create dates preserved as custom merge fields.
Rechat
Contact custom properties
Mailchimp
Merge Fields
1:1Rechat custom fields on contacts consolidate into Mailchimp merge fields. Standard plans cap at 30 merge fields per audience; Premium allows 80. We group related properties (e.g., multiple address fields into a single ADDRESS merge field) and flag fields exceeding the limit for manual placement or tagging strategy.
Rechat
Company
Mailchimp
Merge Field (COMPANY) + Tags
1:1Rechat company name maps to Mailchimp's built-in COMPANY merge field. Industry, annual revenue, and employee count migrate as additional merge fields or contact tags depending on segmentation needs. Parent-child company hierarchies collapse to a single company affiliation. We also map the primary company website to a custom merge field for reference, and any subsidiary relationships are flattened to ensure each contact carries a single company affiliation in Mailchimp.
Rechat
Deal / Pipeline
Mailchimp
No Equivalent
1:1Rechat deal pipelines with stages, amounts, and close dates have no Mailchimp equivalent. Mailchimp tracks campaign engagement, not pipeline progress. Deal data migrates as contact tags or custom fields for reference but cannot drive workflow automation. Deal stage labels are stored as tags, letting you segment contacts by sales phase, and we provide a mapping table linking each tag to the original Rechat stage.
Rechat
Listing / Search / Tour
Mailchimp
No Equivalent
1:1Rechat's real estate-specific objects — Listings, Searches, Tours — are MLS-derived data with no Mailchimp counterpart. We export these as JSON alongside the migration and document the schema for any custom rebuild you may want using Mailchimp's custom audience fields or third-party integrations.
Rechat
Email metadata (Subject, Date, Teaser)
Mailchimp
Activity Log (custom fields)
1:1Rechat stores email metadata (subject line, date, teaser) retrieved on-demand from Gmail/Outlook. This migrates as contact-level custom fields capturing last contacted date and subject. Full email body content is not stored in Rechat and cannot migrate. We also map the email thread identifier to a custom field so you can reference the original conversation in Gmail or Outlook if needed.
Rechat
User / Agent
Mailchimp
Custom Merge Field (AGENT)
1:1Rechat agents with user_type, features array, and MLS associations have no Mailchimp equivalent. Agent attribution (which agent owns the contact) migrates as a custom merge field (AGENT_EMAIL__c or similar). The agent's Rechat user profile and permissions do not transfer. If you need to route campaigns based on agent territory, you can use the AGENT_EMAIL__c field to filter segments, though Mailchimp does not natively support owner-based assignment.
Rechat
Tags / Labels
Mailchimp
Tags
1:1Rechat contact tags map 1:1 to Mailchimp subscriber tags. Tags are the primary mechanism for preserving Rechat's label system in Mailchimp without consuming merge-field slots. Tag-based segmentation works natively in Mailchimp. You can also create dynamic segments based on tag combinations, and tags can be used in automation triggers to send follow‑up emails when contacts are added to specific groups.
Rechat
Suppression data (bounces, unsubscribes)
Mailchimp
Suppression List
1:1Rechat contacts with bounce or unsubscribe status export as Mailchimp non-subscribed contacts in the suppression list. This preserves suppressions across the migration and protects sender reputation and deliverability from day one. We also verify that the suppression list size matches the exported count and flag any addresses that appear in both the active audience and the suppression list to avoid duplicate entries.
Rechat
Calendar / Meeting metadata
Mailchimp
No Equivalent
1:1Rechat calendar events and meeting metadata sync from Gmail/Outlook but store no body content. Meeting titles and timestamps migrate as contact-level custom fields if meaningful, but Mailchimp has no native scheduling or meeting tracking capability. We recommend exporting any required meeting context to a separate system for future reference, as Mailchimp’s features are focused on audience engagement rather than calendar management.

Migration approach
Audit Rechat data model and field inventory
FlitStack AI extracts a full inventory of Rechat contact properties, company properties, deal fields, and custom objects via the Rechat API. We count total custom fields per object and flag contacts with properties exceeding Mailchimp's merge-field limit (30 standard, 80 Premium). We also identify tag usage, suppression candidates (bounced, unsubscribed contacts), and any MLS-derived fields. The output is a field-consolidation plan before any data moves.
Design Mailchimp audience schema and merge-field mapping
Based on the inventory, we design the target Mailchimp audience: which built-in merge fields to use (FNAME, LNAME, COMPANY, PHONE, ADDRESS), which fields become custom merge fields, and which properties consolidate into multi-value fields or migrate as tags. We create the audience in Mailchimp with the correct merge-field configuration before any records load. If your plan tier constrains merge-field count, we document the trade-offs and get your sign-off before proceeding.
Build suppression list from Rechat bounce and unsubscribe data
We export all Rechat contacts with bounce, spam-report, or unsubscribe status and import them into Mailchimp as non-subscribed contacts in your suppression list. This step runs before the primary contact migration to ensure Mailchimp rejects sends to these addresses from day one, protecting your sender reputation and deliverability scores. We verify the suppression list count against Mailchimp's suppression list dashboard before the main migration starts.
Migrate contacts with batch sequencing respecting API rate limits
Contacts move from Rechat to Mailchimp in batched API calls sequenced to respect Mailchimp's 10 simultaneous connection limit and 120-second timeout. Owner/agent attribution from Rechat maps to AGENT_EMAIL__c custom merge fields. Tags carry over 1:1. Rechat's original create date and update timestamp migrate as custom datetime fields. We run field-level validation comparing source values against destination merge fields after each batch.
Run delta pickup and deliver migration audit log
After the primary migration window, a delta-pickup phase captures any Rechat contacts modified or added during the cutover (typically a 24–48 hour window). We generate an audit log listing every record migrated, the mapping applied, any records that failed validation, and the resolution. You receive a field-level reconciliation report showing record counts by object, tag counts, suppression list size, and any merge fields that were consolidated or truncated.
