Overview
Moving from Smart CRM Online to Mailchimp is a fundamentally different migration than CRM-to-CRM moves. Smart CRM Online has no documented API, so we extract all data through its native CSV export, which means Deals, Pipeline Stages, and engagement history require manual decision-making about what to discard, what to encode as tags, and what to leave behind. Mailchimp's data model centers on Members within an Audience, with Companies mapped as tags or static segments rather than a first-class object. We sequence the export by first pulling Companies (to establish tag values), then Contacts with Company associations resolved, and we validate email addresses and opt-in status before loading into Mailchimp's audience API. Workflows, automations, and Deal records do not migrate; we deliver a written inventory of any Smart CRM Online automations for the customer's team to rebuild in Mailchimp's automation builder.

Object mapping
Each row shows how a Smart CRM Online 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.
Smart CRM Online
Contact
Mailchimp
Member
1:1Smart CRM Online Contact records map directly to Mailchimp Members within a designated Audience. The Contact email address becomes the Member email; first name and last name map to FNAME and LNAME merge fields. We validate email format and flag bounced or invalid addresses before the Mailchimp import run to avoid generating unsubscribed or cleaned records. The Contact's associated Company name becomes a Mailchimp tag on the Member record during import. Phone number maps to the PHONE merge field if configured in the destination Audience.
Smart CRM Online
Company
Mailchimp
Tag or Static Segment
lossyMailchimp has no standard Company or Account object. Companies from Smart CRM Online map either to Mailchimp Tags (applied per Member) or to a Static Segment that we create during migration, depending on whether the customer needs dynamic list management or a fixed segment for a one-time campaign push. We confirm the strategy during discovery. If Tags are used, the company name is normalized (trimmed whitespace, consistent casing) and applied to all Members with that Company association. If Static Segments are used, we create one segment per Company and add all associated Members to it during import.
Smart CRM Online
Deal
Mailchimp
Merge Field (or excluded)
lossyMailchimp has no Deal or Opportunity object. Deal records from Smart CRM Online cannot map to a standard Mailchimp field. During scoping, we present two options: encode the Deal as a custom merge field (TEXT type, named deal_value or last_deal_stage) on the Member record if the customer wants to preserve the most recent Deal value for marketing segmentation; or exclude Deals entirely from the migration payload and flag the exclusion in the handoff document. Pipeline Stages associated with Deals are not migrated unless the customer selects the merge field option, in which case the most recent stage name is stored as a TEXT merge field.
Smart CRM Online
Tag
Mailchimp
Tag
1:1Smart CRM Online Tags applied to Contacts map directly to Mailchimp Tags on the corresponding Member record. Tags are applied during the Member import phase via the Tags endpoint (POST /lists/{list_id}/members/{subscriber_hash}/tags). Tag names are normalized to Mailchimp's tag length limit (255 characters) and checked for special characters that could cause import failures. Tags on Companies are not imported unless the Company has associated Contacts being migrated.
Smart CRM Online
Custom Properties
Mailchimp
Merge Fields
lossySmart CRM Online custom fields per Contact are mapped to Mailchimp Merge Fields on the destination Audience. We define the merge field type during discovery: TEXT for string values, NUMBER for numeric, DATE for date-formatted values, and ADDRESS for address blocks. Merge fields are created via the Mailchimp Merge Fields API before the Member import begins. Any Smart CRM Online custom field with no clear Mailchimp equivalent is flagged in the handoff document for the customer to decide whether to create the field or drop it.
Smart CRM Online
Pipeline Stage
Mailchimp
Excluded
lossySmart CRM Online Pipeline Stages are configuration metadata tied to Deal records. Since Deals do not migrate to Mailchimp, Pipeline Stages are excluded from the migration payload. If the customer has selected Deal merge field encoding (see Deal mapping), the most recent Pipeline Stage name is stored as a TEXT merge field on the Contact's Member record rather than as a standalone object.
Smart CRM Online
Activity (calls, emails, meetings, tasks)
Mailchimp
Excluded
lossySmart CRM Online activity logs (calls, emails, meetings, tasks) associated with Contacts or Deals are not migrated to Mailchimp. Mailchimp tracks campaign-level engagement (opens, clicks, bounces, unsubscribes) but does not store sales call logs, meeting records, or task completions as structured data. We include a note in the handoff document listing the activity types present in the Smart CRM Online export so the customer's team can determine whether any of this data has regulatory retention requirements before the source system is decommissioned.
Smart CRM Online
Owner
Mailchimp
Excluded
lossySmart CRM Online Owner records (the rep assigned to a Contact or Deal) have no Mailchimp equivalent. Mailchimp does not have a user-assignment model for Members. Owner information is excluded from the migration payload. If the customer needs to track which rep owns a contact, we recommend creating a Owner_name merge field on the Member record, populated from the Smart CRM Online Owner name field.

Migration approach
Discovery and export verification
We request a full data export from Smart CRM Online covering Contacts, Companies, Deals, Tags, and any custom field exports available. We parse the CSV headers to identify standard versus custom fields, assess contact volume, and flag any Deals or Pipeline Stage records present in the export. We also request a sample of the activity export if available. During this step we confirm the customer's preferred Companies-to-Segments strategy (Tags versus Static Segments) and decide whether Deal data should be encoded as merge fields or excluded.
Mailchimp audience and merge field configuration
We create the destination Mailchimp Audience and configure all required merge fields via the Mailchimp Merge Fields API before importing any Members. Merge field types are assigned based on the data type inferred from the Smart CRM Online export (TEXT for strings, NUMBER for integers and decimals, DATE for date values). If the customer selected Static Segments for Companies, we pre-create one segment per Company during this step. The Mailchimp API key and list ID are provided by the customer during scoping.
Data extraction and transformation
We extract Contacts, Companies, Tags, and Deals from the Smart CRM Online CSV exports. The transformation step builds a Contact-to-Company lookup map from the Company export, resolves Contact-Company associations by matching the Company ID or name reference in the Contact export, normalizes tag names, validates email address format, infers opt-in status, and builds the Deal-to-Contact mapping for merge field population if the Deal option was selected. Any records with invalid or missing email addresses are separated into a quarantine file for customer review.
Batch import into Mailchimp
We import Members into Mailchimp using the batch import endpoint (POST /batches) with a chunk size of 1,000 records per batch. Each batch includes the applied Tags (from the Smart CRM Online Tags export) and any merge field values resolved during transformation. We poll the batch status endpoint until all batches complete and validate the imported Member count against the source export count. Tag application is confirmed separately via the Tags endpoint for each batch of Members.
Validation and segment reconciliation
We run a reconciliation check comparing the Smart CRM Online Contact count against the Mailchimp Audience Member count. We spot-check 25-50 Member records for correct FNAME, LNAME, email, tag assignment, and merge field values against the source CSV. If the customer selected Static Segments, we verify segment membership counts. Any discrepancies are traced back to the source transform and corrected before the next batch run. The customer reviews the validation report and approves final cutover.
Cutover and automation inventory handoff
We freeze the Smart CRM Online export from further writes, run a final delta export to capture any contacts added or modified during the migration window, import the delta into Mailchimp, and mark the migration complete. We deliver a written inventory of any Smart CRM Online automations or workflows present in the account, with a brief description of each and a recommendation for rebuilding in Mailchimp's automation builder. We do not rebuild automations as part of the migration scope. We provide a one-week post-migration support window for reconciliation issues raised during the first send campaign.
