Overview
Moving from Sharp CRM to Mailchimp is a functional migration from a full CRM to an email marketing platform, not a record-for-record copy. Sharp CRM stores Contacts, Companies, Deals, Tasks, and Activity history in a relational model; Mailchimp stores contacts in an Audience with tags, groups, and segments as the primary organization layer. We migrate the contact records and their associated tags first, preserving Sharp CRM's subscriber status (subscribed, unsubscribed, cleaned) in Mailchimp's status fields. Custom fields from Sharp CRM are enumerated at scoping and mapped to Mailchimp merge fields where a type match exists. Deals, Tasks, and Activity history have no direct Mailchimp equivalents and are documented separately for your team to decide whether to export them as a reference archive. Sharp CRM automations do not export; we deliver a written inventory of every active workflow with a Mailchimp automation builder equivalent.

Object mapping
Each row shows how a Sharp CRM 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.
Sharp CRM
Contact
Mailchimp
Audience Member (Subscriber)
1:1Sharp CRM Contacts map directly to Mailchimp Audience members. The primary fields (first name, last name, email address, phone number, physical address) map to Mailchimp's FNAME, LNAME, EMAIL, PHONE, and address merge fields. Subscriber status in Sharp CRM (active, unsubscribed, bounced) maps to Mailchimp's SUBSCRIPTION_STATUS field using the Mailchimp API's status parameter (subscribed, unsubscribed, cleaned, pending). We extract the status at migration time and set it correctly in Mailchimp so that suppression rules and CAN-SPAM compliance are maintained from day one.
Sharp CRM
Tag
Mailchimp
Tag
1:1Sharp CRM Tags applied to Contacts map directly to Mailchimp Tags on the same Audience member. Tags are flat string labels in both systems, so no transformation is required. If Sharp CRM has applied multiple tags to a single contact, we apply all of them to the corresponding Mailchimp member. Tags are migrated before any segmentation so that tag-based segments can be rebuilt in Mailchimp Customer Journeys.
Sharp CRM
Company
Mailchimp
Merge Fields (Company Name, Address)
lossySharp CRM Companies store organization-level data. Mailchimp does not have a native Company or Account object, so company data is stored as merge field values on the Contact. We map the Sharp CRM company name to a text merge field (COMPANY or business_name) and the primary business address to the standard address merge fields. If multiple Sharp CRM Contacts share the same Company, each receives the same company-level field values in Mailchimp. We do not create a separate company record in Mailchimp because that object does not exist in standard Mailchimp.
Sharp CRM
Deal
Mailchimp
Reference Archive (No Direct Mapping)
lossySharp CRM Deals carry pipeline stage, value, close date, and associate to Contacts and Companies. Mailchimp has no deal, opportunity, or pipeline tracking capability. We do not migrate Deals as live records. We export Deal data (stage, value, close date, associated contact email) to a CSV reference archive that the customer can store externally or import into a spreadsheet tool. The customer decides whether to use this archive for reporting or to keep a legacy system read-only access.
Sharp CRM
Task
Mailchimp
Reference Archive (No Direct Mapping)
lossySharp CRM Tasks include title, due date, assignee, and status. Mailchimp does not have a task management or to-do tracking system. We export Tasks to a CSV reference archive with the task title, due date, assignee email, status, and associated contact email. The customer uses this archive to recreate tasks in their preferred project management tool. Tasks are not imported into Mailchimp because they would have no home object to attach to.
Sharp CRM
Activity (Call, Email, Meeting, Note)
Mailchimp
Reference Archive (No Direct Mapping)
lossySharp CRM Activity history (calls, emails, meetings, notes) attaches to Contacts and Companies in a relational timeline. Mailchimp tracks campaign-level engagement (opens, clicks, bounces) per subscriber but has no per-contact activity timeline. We export Activity records to a CSV reference archive keyed by contact email and activity type, with the original timestamp and body content preserved as plain text. The customer can use this archive for historical reference or import it into a separate CRM if they adopt one later.
Sharp CRM
Custom Field
Mailchimp
Merge Field
1:1Sharp CRM custom fields are common across agency and vertical-specific accounts. We enumerate every custom field during scoping, classify each by data type (text, number, date, dropdown, checkbox, phone), and map them to Mailchimp merge fields of matching type. Text fields map to Mailchimp text merge fields, number fields to number merge fields, dates to date merge fields, and dropdowns to dropdown merge fields with the same option values. Checkbox fields that store true/false or multi-select values map to Mailchimp text fields with comma-separated values. Any custom field without a clear type match is flagged for the customer to resolve before import.
Sharp CRM
User
Mailchimp
Mailchimp User Account (Provisioned Separately)
1:1Sharp CRM User records (name, email, role) represent team members who log into the platform. Mailchimp User accounts are provisioned directly inside Mailchimp's Account Settings and are not created via contact import. We provide the customer with a list of Sharp CRM users and their email addresses so that the corresponding Mailchimp accounts can be provisioned with matching roles (Admin, Author, Manager, Viewer) before the contact migration begins. User provisioning is a manual step that the customer completes; we do not create Mailchimp user accounts as part of the data migration scope.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Sharp CRM gotchas
No documented public API in the research record
Workflows and automations do not export natively
Custom fields are common and require per-customer mapping
Pipeline stage definitions must be mapped manually
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
Export path confirmation
We begin by asking the customer what export options they see in their Sharp CRM account. We request screenshots of any export functions, CSV download buttons, or API access screens. If a native CSV export covers Contacts, Companies, Tags, and custom fields, we use it as the primary data source. If only partial exports are available, we identify which objects require separate field-level exports and adjust the timeline for multi-step file processing. We do not begin schema mapping until the export path is confirmed because the available fields determine the full mapping scope.
Data extraction and initial audit
We extract Sharp CRM data in the following order: Contacts (primary export), Companies (linked to Contacts by email domain or company_id), Tags (from the contact export or a separate tag export), Custom Fields (field-level export for each industry-vertical custom property), and Deals and Tasks (for the reference archive). We audit the extracted files for record counts, completeness, duplicate email addresses, and missing required fields (email address is mandatory for Mailchimp import). Any Sharp CRM contact without a valid email address is excluded from the Mailchimp Audience and added to a separate invalid-address report for the customer to clean or follow up with manually.
Audience design and merge field creation
We design the Mailchimp Audience before any import. This includes creating merge fields that correspond to Sharp CRM custom fields, with types matched (text, number, date, dropdown, address) and option values populated for dropdown fields. We configure the audience settings: default from name, default from email, and email subject line. We create the tagging structure in Mailchimp to match Sharp CRM's tag taxonomy so that tag-based segments can be rebuilt. Subscriber status (subscribed, unsubscribed, cleaned) is set at import time using the Mailchimp API status parameter, not by post-import field updates.
Mailchimp import and tag application
We import Contacts into Mailchimp using the API (for large audiences above 10,000 records) or CSV upload (for smaller audiences under 10,000). For API imports, we use batch operations with rate-limit handling and exponential backoff. For CSV imports, we use Mailchimp's native import wizard with field-to-merge-field mapping confirmed before submission. After contacts are imported, we apply tags by referencing the Sharp CRM tag field and mapping each tag name to a Mailchimp tag. Tags are applied in a second batch operation to avoid tag-application failures if the contact import batch encounters errors.
Reference archive export and delivery
We export Sharp CRM Deals, Tasks, and Activity history to separate CSV files with a consistent schema: record type, primary contact email, and all relevant fields. These files are delivered as a reference archive alongside the migration completion report. We include a data dictionary for each archive file explaining what each column contains and what the record represents in Sharp CRM. The customer uses these archives to decide whether to import them into a separate CRM, keep them as a historical record, or archive them externally. We do not import these records into Mailchimp because they have no corresponding object.
Automation inventory and rebuild handoff
We deliver a written automation inventory documenting every active Sharp CRM workflow observed during the discovery call. For each automation, we record: automation name, trigger type, conditions, sequence of actions, and any CRM objects affected. We provide a recommended equivalent using Mailchimp Customer Journeys builder blocks (trigger, condition, delay, email action). The customer's marketing team rebuilds automations inside Mailchimp using this document as their guide. We do not rebuild automations as part of the migration scope because Mailchimp Customer Journeys require marketing team input on campaign content and send logic.
