Overview
MarketSharp stores contacts as part of a lead-to-job lifecycle: leads, accounts, contacts, appointments, jobs, and custom fields tied to the contractor-sales workflow. Mailchimp stores subscribers in an Audience with merge fields, tags, and segment filters. These are fundamentally different data models — MarketSharp is a relational CRM; Mailchimp is an email-marketing list with lightweight contact properties. We migrate what Mailchimp can represent natively: subscriber records with their email, name, phone, and any text-based custom fields. We map MarketSharp lead tags to Mailchimp tags, preserving segmentation logic. We flag custom fields that exceed Mailchimp's 255-character merge-field limit. Workflows, job records, appointment calendars, and pipeline stages have no Mailchimp equivalent and must be rebuilt manually or decommissioned. We sequence the migration so contacts with the same email address collapse to a single Mailchimp subscriber, with the most-recently-modified MarketSharp record taking precedence for field values. A 24–48 hour delta-pickup window captures any new MarketSharp entries during cutover before you switch fully to Mailchimp.
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 MarketSharp 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.
MarketSharp
Lead / Contact
Mailchimp
Mailchimp Subscriber
1:1MarketSharp leads and contacts map directly to Mailchimp subscribers by email address. When a MarketSharp contact has the same email as an existing Mailchimp subscriber, we update the existing record using the most-recently-modified MarketSharp field values. Unsubscribe status in Mailchimp is preserved to avoid re-subscribe violations.
MarketSharp
Account / Company
Mailchimp
Mailchimp Merge Field
1:1Mailchimp has no account or company object. MarketSharp company names migrate as a plain-text merge field (COMPANY) on the subscriber record. If multiple MarketSharp contacts share one company, each Mailchimp subscriber receives the same company-name value independently — there is no relational link between subscribers in Mailchimp.
MarketSharp
MarketSharp Tags
Mailchimp
Mailchimp Tags
1:1MarketSharp applies tags to leads and contacts to categorize prospects by source, trade type, or project category. We map each MarketSharp tag to a Mailchimp tag of the same name. Mailchimp applies tags at the subscriber level, so a subscriber can carry multiple tags exactly as in MarketSharp. Tags with more than 30 characters are truncated to Mailchimp's tag-length limit.
MarketSharp
Lead Status
Mailchimp
Mailchimp Segment or Merge Field
1:1MarketSharp tracks lead status (New, Contacted, Qualified, etc.) as a pick-list field. Mailchimp has no native lead-status concept. We map each MarketSharp status value to a Mailchimp tag (e.g., status-Contacted) so you can recreate segments in Mailchimp that filter by original lead status without requiring a custom merge field.
MarketSharp
Phone Number
Mailchimp
Mailchimp Phone Merge Field
1:1MarketSharp stores primary and secondary phone numbers on contacts. Mailchimp's PHONE merge field accepts US and international formats. We map MarketSharp's primary phone to PHONE; secondary phone maps to a custom merge field (PHONE2) that we create in your Mailchimp audience before migration.
MarketSharp
Address Fields
Mailchimp
Mailchimp Address Merge Fields
1:1MarketSharp address components (street, city, state, zip, country) map to Mailchimp's ADDRESS merge field group (ADDR1, CITY, STATE, ZIP, COUNTRY). Mailchimp's address merge field renders as a formatted block in campaigns — this preserves location data for geographic segmentation and personalization.
MarketSharp
Job / Project Records
Mailchimp
No Equivalent
1:1MarketSharp stores job records with job type, scope, pricing, and scheduling data tied to a contact. Mailchimp has no job, project, or service-record object. We cannot migrate job data to Mailchimp — it must be archived separately or moved to a project-management tool if needed. We export job records as a JSON file for your records.
MarketSharp
Appointment / Calendar Events
Mailchimp
No Equivalent
1:1MarketSharp tracks appointments with date, time, salesperson, and location. Mailchimp is an email platform with no calendar or scheduling capability. Appointment records cannot migrate. We export appointment history as a CSV for reference but do not create Mailchimp records from them.
MarketSharp
MarketSharp Custom Lead Fields
Mailchimp
Mailchimp Merge Fields (or Tags)
1:1MarketSharp allows custom fields on leads (e.g., Trade Type, Lead Source Detail, Project Size Estimate). We map text, number, and date custom fields to Mailchimp merge fields created in your audience before migration. Fields exceeding 255 characters are either truncated or migrated as subscriber notes. Multi-select pick-list fields become comma-separated text in Mailchimp.
MarketSharp
Unsubscribe / Do-Not-Contact List
Mailchimp
Mailchimp Suppression List
1:1MarketSharp contacts flagged as do-not-email or bounced are imported with their correct Mailchimp status. Those with do-not-email flags land as unsubscribed in your Mailchimp suppression list, and bounced email records become cleaned. We cross-check against your existing suppression list to prevent reactivating previously suppressed addresses, protecting your sender reputation and ensuring CAN-SPAM compliance throughout the migration.

MarketSharp gotchas
Custom Lead Fields vary per installation
Reporting export requires manual trial-and-error
Webhook functionality is limited and not self-serve
Division-segmented data requires multi-pass export
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms

Migration approach
Audit MarketSharp export and build Mailchimp audience schema
We connect to MarketSharp via its API using your credentials and pull a full export of leads, contacts, and associated tags and custom fields. Simultaneously, we analyze your Mailchimp account and create the merge fields needed (PHONE2, COMPANY, TRADE, STATUS_MS, EST_VAL, ORIG_DATE, MOD_DATE, MS_ID) before any records land. We flag any MarketSharp custom fields exceeding 255 characters so you can decide whether to truncate, archive, or exclude them.
Resolve email deduplication and unsubscribe suppression
MarketSharp contacts may share email addresses (e.g., a husband and wife on the same renovation project). Mailchimp requires unique email addresses per subscriber. We deduplicate by email, keeping the most-recently-modified MarketSharp record as the authoritative version. We also cross-reference MarketSharp's do-not-email flags and bounced-email records against your existing Mailchimp suppression list and ensure those subscribers land with unsubscribed or cleaned status — never reactivated.
Map lead status and tags to Mailchimp tags before subscriber import
Before importing subscribers, we create Mailchimp tags corresponding to MarketSharp lead-status values and your active tag taxonomy. This preparatory tagging ensures tags are ready to receive their subscribers on import without delays. We run a dry-run pass on a 100-record sample to verify tag application, merge field population, status assignment, and deduplication behavior before committing to the full dataset, allowing us to catch any mapping errors early.
Run full migration with field-level validation report
The full subscriber import runs against your Mailchimp audience using batched API calls. We generate a comprehensive field-level validation report showing the before-and-after state for every record: which fields populated correctly, which were truncated due to character limits, which received their assigned tags, and which landed with non-standard status such as unsubscribed or cleaned. You review this report before cutover and flag any records needing correction before we proceed.
Delta-pickup window and job/appointment data export
After validation sign-off, we open a 24–48 hour delta-pickup window during which any new MarketSharp contacts or modified records are pulled into Mailchimp. We simultaneously export all MarketSharp job records, appointment history, and pipeline data as structured CSV and JSON files for your archive. Once the delta window closes, your MarketSharp account is placed in read-only mode for reference and the full Mailchimp audience is ready for campaign sending.
