Overview
Moving from Simple Sales Tracking to Mailchimp is a directional shift: Simple Sales Tracking is a flat-rate sales CRM built around Leads, Opportunities, Accounts, and pipeline stages, while Mailchimp is a contact-based email marketing platform built around Audiences, Members, Tags, and Campaigns. The migration centers on Contacts and the account-level data attached to them. Opportunities and pipeline stage information have no native Mailchimp equivalent; we preserve what we can as custom fields and tags and flag the rest for manual rebuild. We handle Simple Sales Tracking's iterative API extraction (no bulk export endpoint) with paginated polling and checkpointing, and we resolve Mailchimp contact-tier limits during scoping so the customer is not surprised by pricing adjustments post-import.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Simple Sales Tracking 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.
Simple Sales Tracking
Contact
Mailchimp
Member (Audience)
1:1Simple Sales Tracking Contacts map directly to Mailchimp Members within a target Audience. Email address is the unique identifier and dedupe key. We use Mailchimp's batch upsert endpoint (PUT /lists/{list_id}/members/{subscriber_hash}) with the status_if_new parameter to handle new vs. existing Members during import. First name, last name, phone, and address fields map to Mailchimp merge fields (FNAME, LNAME, PHONE, ADDRESS). Original Contact creation date migrates as a custom merge field mc_original_created_date__c for audit.
Simple Sales Tracking
Account
Mailchimp
Merge Fields or Tags on Member
1:1Simple Sales Tracking Account records carry company name, industry, address, and website. We attach Account name as a merge field (COMPANY) on each Member and use Tags to carry industry classification and account-level labels. Website URL migrates as a custom merge field URL. If the customer uses multiple Mailchimp Audiences segmented by company type, we split the import into separate Audience lists and apply the corresponding tags.
Simple Sales Tracking
Lead
Mailchimp
Member with Tag
1:1Simple Sales Tracking Leads migrate as Members with a Tag of 'Lead' to distinguish them from converted Contacts. Lead source labels (referral, web form, trade show) become Tags on the Member record. We preserve the Lead status field as a custom merge field lead_status__c. If the customer plans to use Mailchimp's segmentation to re-engage cold leads, the tag-based segmentation replaces the Lead nurturing workflows that did not exist in Simple Sales Tracking.
Simple Sales Tracking
Opportunity
Mailchimp
Tags + Custom Merge Fields
lossyMailchimp has no Opportunity or pipeline object. Opportunity fields (deal amount, stage, close date, owner) that the customer wants to preserve migrate as custom merge fields: opp_amount__c, opp_stage__c, opp_close_date__c. Pipeline stage names migrate as Tags so the customer can filter Members by deal stage using Mailchimp segmentation. Commission tracking data from Simple Sales Tracking migrates as opp_commission__c. The customer should plan to manage deal pipeline data in a separate tool or a spreadsheet after migration since Mailchimp does not support pipeline views.
Simple Sales Tracking
Custom Sales Record Fields
Mailchimp
Merge Fields (per field)
lossySimple Sales Tracking allows custom fields on Sales Records. We inspect the account's current custom field definitions during discovery (via screen capture or sample export) and create matching Mailchimp merge fields before import. Mailchimp supports text, number, date, phone, and address merge field types. Dropdown-style custom fields map to Mailchimp radio or dropdown merge field types if the customer requires controlled vocabulary. Merge field limits vary by Mailchimp plan: Essentials and Standard allow up to 80 merge fields per Audience.
Simple Sales Tracking
Appointment
Mailchimp
Not migrated (no equivalent)
1:1Mailchimp has no calendar or appointment object. Appointments from Simple Sales Tracking are not migrated. The customer receives a written list of appointment records with contact name, date, time, and duration for manual re-entry in a calendar tool. We flag this gap in the scope document during discovery.
Simple Sales Tracking
Task
Mailchimp
Not migrated (no equivalent)
1:1Mailchimp does not have a task management layer. Task records (open, completed, or historical) from Simple Sales Tracking do not migrate. Completed tasks have limited business value for a Mailchimp audience; open tasks are the responsibility of the customer's team to re-create in their chosen task tool. We do not attempt to store task data as Member notes because it would inflate the contact record without operational utility.
Simple Sales Tracking
Note
Mailchimp
Member Notes or Tags
1:1Simple Sales Tracking Notes attached to Contacts or Accounts migrate as Notes on the Mailchimp Member record. Free-text note content is preserved verbatim. Notes attached to Opportunities are stored as tags prefixed with 'note:' to make them searchable via Mailchimp segmentation. Formatting and embedded file links within notes are not preserved; file links migrate as text URLs for manual retrieval.
Simple Sales Tracking
Files and Attachments
Mailchimp
Content Studio
1:1Files and documents attached to Contacts, Accounts, or Notes in Simple Sales Tracking are exported as individual downloads from the 1 GB shared storage pool. We re-upload each file to Mailchimp Content Studio and attach the Content Studio URL as a custom merge field file_attachment__c on the relevant Member record. This preserves the file linkage without duplicating the content in Mailchimp's own storage layer.
Simple Sales Tracking
Lead Source
Mailchimp
Tags on Member
1:1Lead Sources in Simple Sales Tracking are a configurable taxonomy of origin labels. Each label migrates as a Tag on the Member record with the tag name matching the source label exactly. Mailchimp's segmentation engine uses Tags as the primary audience-filtering dimension, so lead source tags enable the customer to build segments such as 'web_form_leads' or 'referral_leads' for targeted campaigns immediately after migration.

Simple Sales Tracking gotchas
Trial import ceiling of 50 records masks true data volume
No public bulk export API requires iterative extraction
Custom field definitions are not exposed via a schema endpoint
Activity Feed is a real-time stream with no historical query API
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
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Discovery and contact-volume estimate
We audit Simple Sales Tracking for record counts across Contacts, Leads, Accounts, Opportunities, custom field definitions, and file attachments. We pull a sample of 50-100 records via the API to confirm field names and data formats. We estimate post-dedupe contact volume (by email address) and present Mailchimp pricing tier implications for the target audience. We ask the customer to provide a screen capture of their custom field configuration page to build the merge field schema before extraction begins.
Audience design and merge field creation
We create the target Mailchimp Audience and pre-provision all required merge fields (FNAME, LNAME, PHONE, ADDRESS, COMPANY, URL, and any custom fields identified during discovery). If the customer needs multiple Audiences segmented by account type or lead source, we design the audience split strategy and apply the appropriate tags during import. We confirm the merge field type mappings (text, number, date, dropdown) match the source data formats before any data is written.
Suppression list export
We extract bounced, unsubscribed, and spam-reported contacts from Simple Sales Tracking (where tracked) and prepare a suppression import file for Mailchimp. If the customer used BCC Email integration, any contacts that bounced through the SMTP routing may not have a recorded bounce status in Simple Sales Tracking; we flag this and recommend running a re-confirmation campaign before the first Mailchimp send to protect deliverability.
Iterative data extraction from Simple Sales Tracking
We run paginated API polling against Simple Sales Tracking Contacts, Leads, Accounts, Opportunities, Notes, and custom field endpoints. We checkpoint progress between page fetches to handle mid-export timeouts. File attachments are downloaded as individual binary objects from the document storage layer. All extracted data is staged in a temporary import buffer with a migration manifest that records source record ID, object type, and extraction timestamp for reconciliation.
Data transformation and audience import
We transform the extracted records into Mailchimp batch-upsert format. Each Contact or Lead becomes a Member with the correct status (subscribed, pending, or unsubscribed). Account data attaches as merge fields and tags on the Member. Opportunities map to custom merge fields and tags as configured in the schema design. Notes migrate as Member notes. Files re-upload to Content Studio and URLs attach as merge fields. We run the import via Mailchimp's batch API with chunking to avoid request timeout on large audiences.
Cutover, validation, and documentation delivery
We run a final delta scan of Simple Sales Tracking for any records modified during the migration window and upsert the delta into Mailchimp. We deliver a reconciliation report comparing source record counts to Mailchimp Member counts by tag and by merge field. We deliver a written inventory of unmigrated objects (Appointments, Tasks, pipeline views) with recommended manual actions. We do not migrate Simple Sales Tracking Workflows or automations as Mailchimp Customer Journeys because they require manual design in the Mailchimp automation builder; we deliver a one-page note on which contact events the customer should trigger Customer Journeys from.
