Overview
Real Geeks is a real estate CRM built around lead capture and follow-up tracking. Its data model centers on Leads (with urgency, timeframe-to-buy, status, and source attribution), saved searches, and property-view activity logs that signal buyer intent. Mailchimp is an email marketing platform that organizes subscribers into Audiences with Contacts, Tags, and Merge Fields. The migration carries Real Geeks leads into Mailchimp contacts, maps Real Geeks urgency tiers and timeframes to Mailchimp Tags for segmentation, preserves source attribution as merge fields, and translates property-search activity into descriptive tags so your Mailchimp segments can recreate the buyer-readiness logic you used in Real Geeks. Real Geeks drip campaigns and automated follow-up sequences have no Mailchimp equivalent at the data layer — FlitStack exports the campaign definitions as a reference document so your team can rebuild them in Mailchimp automations. The export runs via Real Geeks CSV export or API pull, contacts land in Mailchimp via bulk import or API, and a 24–48h delta pickup window captures any new leads created during the cutover.

Object mapping
Each row shows how a Real Geeks 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.
Real Geeks
Lead
Mailchimp
Contact (in Audience)
1:1Real Geeks leads map 1:1 to Mailchimp contacts. Email address is the primary key — leads without a valid email address are flagged and held from import because Mailchimp requires a valid email for every contact. Duplicate emails across Real Geeks leads are resolved by keeping the most recently modified record.
Real Geeks
Urgency
Mailchimp
Tag
1:1Real Geeks urgency values (Cold, Warm, Hot, Contacted, Not Contacted) map to Mailchimp Tags applied at import time: RG_Urgency_Cold, RG_Urgency_Warm, RG_Urgency_Hot, RG_Urgency_Contacted, RG_Urgency_Not_Contacted. Custom urgency values are preserved as their exact text in the tag name. These tags let you segment contacts by urgency in Mailchimp campaigns and automations, preserving any custom tier names exactly as they appear in Real Geeks.
Real Geeks
Timeframe
Mailchimp
Tag
1:1Real Geeks timeframe values (Immediately, 1 Week, 2-4 Weeks, 30 Days, 60 Days, 90 Days, 3-6 Months, 6-12 Months, 1 Year Or More) map to Mailchimp Tags like RG_Timeframe_Immediately, RG_Timeframe_1Week, etc. This enables Mailchimp segmentation by buyer readiness without requiring custom merge-field logic.
Real Geeks
Status
Mailchimp
Contact Status
1:1Real Geeks status values map to Mailchimp contact statuses: Active → Subscribed, Cancelled → Unsubscribed, Dead → Archived, In Escrow and Closed Escrow → Subscribed (with RG_Status_Escrow or RG_Status_Closed_Escrow tag applied). This preserves the pipeline stage signal for segmentation. You can use these status tags to trigger automation paths, such as sending escrow‑update emails when a contact receives the RG_Status_Escrow tag.
Real Geeks
Source
Mailchimp
Merge Field
1:1Real Geeks lead source (website, Zillow, Realtor.com, API, etc.) is stored in a custom Merge Field (RG_Source__c) on the Mailchimp contact. Source-based segmentation in Mailchimp is then done by filtering contacts where RG_Source__c equals a specific value. Combining the source merge field with urgency tags enables multi‑dimensional campaigns, such as targeting hot leads from Zillow with property‑search drip content.
Real Geeks
Tag
Mailchimp
Tag
1:1Real Geeks tags on a lead are transferred as Mailchimp Tags verbatim. If a lead has tags [investor, luxury, referral], those exact tags are applied in Mailchimp. This preserves any custom tagging logic your team built in Real Geeks. After migration, you can refine or expand tags in Mailchimp to reflect new marketing segments without affecting the original Real Geeks data.
Real Geeks
Saved Search
Mailchimp
Segment
1:1Real Geeks saved searches represent specific property-criteria sets that leads matched. Mailchimp has no saved-search equivalent — we export each saved search name and the associated lead count as a reference document so your team can recreate segments in Mailchimp using tags and merge-field filters that approximate the original criteria.
Real Geeks
Property Search Activity
Mailchimp
Tag
1:1Real Geeks tracks property searches and listing views per lead. We translate this into descriptive Mailchimp Tags (e.g., RG_Searched_Condo, RG_Viewed_Over_1M, RG_Saved_10_Properties) based on the most recent or most frequent activity type. This gives Mailchimp segmentation capability around property intent without importing the raw activity log.
Real Geeks
Company
Mailchimp
Merge Fields
1:manyReal Geeks companies (name, address, domain) are split into Mailchimp Merge Fields: RG_Company_Name, RG_Company_Address, RG_Company_Domain. Mailchimp has no native company object — if your team needs company-level reporting, we recommend a separate CRM for that, or collapsing company data into contact-level fields.
Real Geeks
Drip Campaign Enrollment
Mailchimp
Automation Reference Export
1:1Real Geeks drip campaign enrollment (which leads were in which sequence, at what step) is exported as a reference CSV: Contact_Email, Campaign_Name, Current_Step, Step_Name, Enrolled_Date. This is not imported into Mailchimp automations but serves as a rebuild guide for your email team to recreate the sequence logic in Mailchimp Customer Journeys.
Real Geeks
Custom Fields
Mailchimp
Merge Fields
1:1Real Geeks custom lead fields map to Mailchimp Merge Fields (MERGE0–MERGE7 on Standard, up to MERGE80 on Premium). Mailchimp's field type support (text, number, date, phone, address, birthday) is matched per field. If field count exceeds the Mailchimp plan limit, we group less-critical fields into a single JSON-formatted merge field for reference.
Real Geeks
Last Communication Date
Mailchimp
Merge Field
1:1Real Geeks last communication date maps to a Mailchimp date-type Merge Field (RG_Last_Communication__c) preserved for reporting continuity. This allows segmentation of leads not contacted in X days without querying the original CRM. You can also use this date in automation triggers, such as re‑engagement emails after a specified inactivity period.

Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration

Migration approach
Audit Real Geeks data model and export contacts
FlitStack connects to your Real Geeks account via API or processes your CSV export. We inventory all standard fields (first_name, last_name, email, phone, address, urgency, timeframe, status, source, tags), custom fields, company records, and activity-history volume. We verify email address count against Mailchimp plan tier and check merge-field limits. You receive a pre-migration data inventory showing exactly what will land in Mailchimp and what will be exported as reference files.
Map urgency, timeframe, and status to Mailchimp tags and contact status
We configure the value-mapping table for urgency tiers (Cold/Warm/Hot → RG_Urgency_* tags), timeframe values (Immediately → 1 Year Or More → RG_Timeframe_* tags), and lead status (Active → Subscribed, Escrow states → Subscribed with tag, Cancelled → Unsubscribed, Dead → Archived). This mapping is documented in the migration plan before any data moves. We also configure which Real Geeks tags map verbatim to Mailchimp tags for contacts that already have your custom tagging logic applied.
Create Mailchimp merge fields and audience structure
Before importing contacts, FlitStack creates the required merge fields in your Mailchimp audience (RG_Source__c, RG_Notes__c, RG_Created_Date__c, RG_Last_Activity__c, RG_Last_Property__c, RG_Saved_Searches__c, RG_Views__c, RG_Company_Name__c, RG_Company_Domain__c, RG_Company_Address__c, RG_Source_ID__c). If your Real Geeks setup exceeds Mailchimp's merge-field limit for your plan tier, we flag this and group the overflow fields into a reference JSON field before the audience is finalized. FlitStack also verifies that the target audience exists in Mailchimp, creating it if necessary, and assigns the appropriate field types to each merge tag. This preparation step ensures that when the contact import runs, all custom data lands in the correct fields without type‑mismatch errors.
Run sample migration with field-level diff
A representative slice of 100–500 Real Geeks leads migrates first, spanning different urgency tiers, timeframes, statuses, and source types. We generate a field-level diff showing what landed in each Mailchimp merge field and what tags were applied. You verify that urgency tagging, timeframe tagging, and source attribution are correct before the full run commits. This step catches email-validation rejections and merge-field overflow issues early.
Execute full migration with delta-pickup window
The full contact migration runs — Real Geeks leads land in Mailchimp as contacts with urgency and timeframe tags, status mapped, merge fields populated, and Real Geeks tags transferred. A delta-pickup window (24–48 hours) captures any new leads created in Real Geeks during the cutover. FlitStack generates an audit log of every imported contact and a summary of any rejected records (with email-validation failure reasons) so your team can follow up. The drip campaign enrollment reference CSV is delivered alongside the migration.
Deliver reference export for Mailchimp automation rebuild
FlitStack delivers the Drip_Campaign_Export.csv — a file listing every contact's email, enrolled campaign name, current sequence step, step name, and enrollment date. Your Mailchimp team uses this as the blueprint for rebuilding Real Geeks drip sequences as Mailchimp Customer Journeys. The saved-search reference document (search name, criteria summary, lead count) is also delivered so your team can create Mailchimp segments that approximate the original buyer-intent segments.
