Overview
SharpSpring to Mailchimp is a deliberate platform-type migration: you are moving from a marketing-automation CRM that combines lead scoring, visual workflow builders, accounts, opportunities, and behavioral tracking in one product to an email-first platform where the primary data model is the Audience — a flat list of contacts with merge fields and tags. FlitStack AI extracts SharpSpring's contacts, companies, leads, opportunities, and custom objects via the SharpSpring API, then loads them into Mailchimp as audience members with corresponding merge fields. SharpSpring's accounts and contacts with their multi-field profiles become Mailchimp contacts with merge field values populated from source properties. One significant migration gap is SharpSpring's visual workflow automations: these have no structural equivalent in Mailchimp Customer Journeys and must be exported as reference documents and rebuilt manually. SharpSpring's deal pipelines and opportunity tracking also have no direct counterpart in Mailchimp — we surface these as tags or contact notes for manual follow-up in an external CRM. The migration runs via Mailchimp's API, using batch operations and de-duplication by email address. A delta-pickup window captures records created or modified in SharpSpring during the cutover window, and FlitStack AI generates a field-level diff so you can verify every mapped value before the full commit.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Sharpspring 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.
Sharpspring
Contact
Mailchimp
Audience Member
1:1SharpSpring contacts migrate directly to Mailchimp audience members by email address. Each contact's primary company data populates Mailchimp merge fields. Multi-company contacts are flattened — the primary company name becomes a merge field value, and secondary company associations surface as tags.
Sharpspring
Lead
Mailchimp
Audience Member
1:1SharpSpring leads map to Mailchimp audience members the same way contacts do. The lead status (New, Contacted, Qualified) is preserved as a Mailchimp tag so you can segment by prior lead stage. Unconverted leads that should not receive marketing email are flagged with a Do-Not-Mail tag before migration.
Sharpspring
Company (Account)
Mailchimp
Merge Fields on Audience Member
many:1SharpSpring's Company object flattens into Mailchimp merge fields on the contact record. Company name becomes COMPANY merge field; industry, annual revenue, and employee count each become dedicated merge fields. Parent-company hierarchy has no Mailchimp equivalent — the top-level company name migrates and subsidiary relationships are noted in a custom reference field.
Sharpspring
Opportunity (Deal)
Mailchimp
Contact Notes + Tags
1:1SharpSpring deal pipelines and opportunity records have no native Mailchimp equivalent. We create a CONTACTNOTE entry on each related contact recording deal name, stage, amount, and close date. Pipeline stage is also added as a tag on the contact. Full pipeline visualization must be rebuilt in an external CRM or spreadsheet if deal tracking is critical.
Sharpspring
Custom Objects
Mailchimp
Mailchimp Merge Fields
1:1SharpSpring custom objects map to Mailchimp merge fields on the audience member. Each custom object field becomes a dedicated TEXT or NUMBER merge field in Mailchimp. If the custom object contains a relationship to a Contact, the field migrates to the member record. Mailchimp's 40-merge-field limit per audience is flagged during audit if your setup exceeds it.
Sharpspring
SharpSpring Tags
Mailchimp
Mailchimp Tags
1:1SharpSpring's tag system migrates 1:1 to Mailchimp tags. Tag names are preserved exactly; multi-word tags keep their spacing. Tags applied programmatically by SharpSpring workflows (e.g., lead-score thresholds) are imported with the contact — your team decides which workflow-triggered tags to replicate in Customer Journeys post-migration.
Sharpspring
Form Submissions
Mailchimp
Mailchimp Member Activity + Tags
many:1SharpSpring form submission history is stored as engagement events on the contact. We migrate each form name as a tag on the contact (e.g., 'form:Contact-Request-2024') with the submission timestamp preserved in a dedicated merge field. This preserves form-level attribution without creating a native Mailchimp form-equivalent.
Sharpspring
Email Engagement (Opens, Clicks)
Mailchimp
Mailchimp Member Activity
1:1SharpSpring records opens, clicks, and unsubscribes per contact. We map these to Mailchimp's built-in activity feed by writing the contact into Mailchimp before sending campaign history, so Mailchimp's own open/click tracking reflects the migrated contact's historical engagement context. This approach preserves the full engagement timeline and enables accurate reporting on campaign performance after the migration.
Sharpspring
VisitorID (Web Tracking)
Mailchimp
Not Migrated
1:1SharpSpring's VisitorID feature identifies anonymous web visitors and associates them with contacts via cookie-based tracking. Mailchimp does not have a visitor-identification feature. This data is inherently tied to SharpSpring's tracking code deployment and cannot be meaningfully migrated. The tracking logic is documented for reference when configuring Mailchimp's website tracking pixel.
Sharpspring
Lead Scoring
Mailchimp
Tags + Segmentation Logic
1:1SharpSpring's numeric lead score (engagement points + fit criteria + decay) has no native Mailchimp counterpart. We export the last-known score as a numeric merge field (Lead_Score__c). You can recreate threshold-based segmentation using Mailchimp segments: create static segments for score ranges using filter conditions on the Lead_Score__c merge field after migration.
Sharpspring
Smart Forms
Mailchimp
Mailchimp Embedded Forms / Signup Bars
1:1SharpSpring's dynamic forms with field-level autocomplete and third-party form mapping have no direct Mailchimp equivalent. We export form field definitions and conditional logic as a reference document. Mailchimp's embedded forms and signup bars can replicate the field structure, but conditional branching logic must be rebuilt in Mailchimp's automation builder.

Migration approach
Audit SharpSpring data export
FlitStack AI connects to your SharpSpring instance via API using scoped read access. We extract all contacts, companies, leads, opportunities, custom objects, tags, and engagement history in a pre-migration audit. This audit also identifies your SharpSpring workflow definitions and lead scoring rules so we can produce the reference documents your team needs for the Mailchimp rebuild phase. During extraction we preserve original create dates, owner assignments, and any custom field metadata to ensure a complete audit trail for the migration.
Design Mailchimp audience schema
We design the Mailchimp audience structure before loading data: create merge fields that correspond to your SharpSpring custom properties, define the tag taxonomy based on your SharpSpring tag inventory and lifecycle stages, and set up segmentation logic that mirrors your SharpSpring list and segment filters. If your SharpSpring setup exceeds Mailchimp's 40-merge-field limit, we prioritize fields and document the overflow.
Run sample migration with field-level diff
A representative sample — typically 100 to 500 records spanning contacts, leads, companies, and a mix of custom field types — migrates to your Mailchimp audience first. We generate a field-level diff comparing each source SharpSpring record against the destination Mailchimp member. You verify merge field mapping, tag application, and de-duplication behavior before the full run commits. The sample set is selected to cover typical contact profiles as well as edge cases such as missing email addresses or duplicate records, allowing you to confirm that mapping handles those scenarios correctly before the full dataset is processed.
Execute full migration with delta pickup
The full record set migrates to Mailchimp via batch API operations, with email-address de-duplication applied at ingestion. A delta-pickup window captures any contacts created or modified in SharpSpring during the cutover period. FlitStack AI generates an audit log covering every record operation, and one-click rollback is available if reconciliation reveals unexpected gaps. During the batch migration, FlitStack AI respects Mailchimp’s API rate limits and retries transient errors automatically, ensuring a smooth ingestion. You can monitor progress through a real-time dashboard that displays the number of records processed, remaining count, and any records flagged for review.
Deliver reference artifacts for workflow rebuild
FlitStack AI exports your SharpSpring workflow definitions as structured JSON documents describing triggers, conditions, and actions for each automation. We also deliver a lead-score reference sheet mapping your SharpSpring score thresholds to Mailchimp segment filter definitions. These artifacts support your team's rebuild of SharpSpring workflows in Mailchimp Customer Journeys and your ongoing lead-score segmentation logic. Each JSON file includes sample payloads and comments that explain the mapping between SharpSpring trigger types and Mailchimp event blocks, giving your developers a clear blueprint for reconstructing automation logic in Customer Journeys.
