Overview
Moving from Claritysoft to Mailchimp is a platform-type shift, not a CRM-to-CRM upgrade. Claritysoft is a full sales CRM with Contacts, Accounts, Leads, Opportunities, Tasks, Activities, and Custom Modules; Mailchimp is an email marketing platform with an audience-contact model that supports subscriber-level custom fields and tags but lacks accounts, lead lifecycles, pipelines, tasks, and native activity timelines. We migrate the Contact core (names, emails, phone, addresses, custom fields, tags) and flag everything else as unsupported. Subscription status (opted-in, bounced, unsubscribed) migrates as Mailchimp-compatible status flags, and we import suppression lists separately to protect deliverability. Claritysoft Workflows, Custom Modules, and Opportunities do not migrate; we deliver a written inventory of automations requiring rebuild in Mailchimp Customer Journey Builder. API access requires Claritysoft Accelerator or Enterprise tier, so we confirm source-plan API availability during scoping.

Object mapping
Each row shows how a Claritysoft 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.
Claritysoft
Contact
Mailchimp
Audience Member
1:1Claritysoft Contacts map directly to Mailchimp Audience Members. We migrate First Name, Last Name, Email Address, Phone Number, and Physical Address fields. The Email Address is the primary key and the field that determines Mailchimp subscriber status. Any contact missing an email address cannot migrate and is flagged for manual handling. Subscription status in Claritysoft maps to Mailchimp status flags: subscribed contacts map as subscribed, bounced emails map to cleaned (bounced), and unsubscribed contacts require a separate suppression list import to prevent re-sending.
Claritysoft
Account
Mailchimp
Audience Member (tag or custom field)
1:1Claritysoft Accounts (Companies) have no direct equivalent in Mailchimp. If the customer requires company-level segmentation in Mailchimp, we encode the Account name as a Mailchimp tag (e.g., tag: 'Account: Acme Corp') or as a custom field (COMPANY_NAME). This encoding is chosen during scoping based on the customer's segmentation needs. Account-to-contact relationships are resolved before migration and the owning Account is added to each contact record as a tag or field. This is a degraded representation of the relationship model, not a native account linkage.
Claritysoft
Lead
Mailchimp
Audience Member (unsubscribed or pending)
lossyClaritysoft Leads have no equivalent in Mailchimp. Mailchimp does not distinguish between a sales prospect and a marketing subscriber. We migrate Leads as Audience Members and set the status based on email consent: leads with explicit email consent migrate as subscribed; leads with no recorded consent migrate as unsubscribed or are excluded from the primary import and held in a reconciliation queue for the customer to re-confirm opt-in before adding to the audience. Lead lifecycle stages (New, Contacted, Qualified) do not transfer because Mailchimp has no lifecycle model.
Claritysoft
Opportunity
Mailchimp
None
lossyClaritysoft Opportunities have no equivalent in Mailchimp. Mailchimp is an email marketing platform, not a sales CRM, and does not track deal amounts, pipeline stages, probabilities, expected close dates, or opportunity history. We do not migrate Opportunities as records. We flag the Opportunity count and stage distribution during scoping and note that pipeline reporting must be rebuilt in Mailchimp (via campaign performance against tagged audience segments representing pipeline stages) or abandoned entirely if the team no longer needs sales pipeline visibility.
Claritysoft
Custom Field (Contact-level)
Mailchimp
Custom Field (Subscriber)
lossyClaritysoft Contact Custom Fields migrate to Mailchimp subscriber custom fields if the Mailchimp plan supports them. Standard tier and above support merge fields (TEXT, NUMBER, DATE, ADDRESS, PHONE, URL, IMAGE, RADIO, DROPDOWN, CHECKBOX). We create each custom field in Mailchimp before import and map the Claritysoft field type to the nearest Mailchimp field type. Multi-select or complex Claritysoft custom fields may encode as comma-separated text in Mailchimp. Advanced Custom Fields with calculated logic (Accelerator/Enterprise tier in Claritysoft) cannot be calculated in Mailchimp; the calculated value is stored as a static text field and the calculation logic is not migrated.
Claritysoft
Tag or Label
Mailchimp
Tag
1:1Claritysoft contact tags map directly to Mailchimp tags. Tags are flat labels in both systems, so the migration is straightforward. We extract all distinct tag values from Claritysoft contacts, create matching tags in Mailchimp before the main import, and apply tags to the corresponding Audience Members during import. Tag counts per contact are preserved. If Claritysoft tags contain hierarchical information (e.g., 'Industry: Manufacturing'), we flatten them to flat tags per Mailchimp's model.
Claritysoft
Activities (Calls, Meetings, Tasks)
Mailchimp
None
lossyClaritysoft Activities (Calls, Meetings, Tasks, Emails) have no equivalent in Mailchimp. Mailchimp does not have a native activity timeline or task management feature. We do not migrate activity records. Historical email engagement data (opens, clicks) from Claritysoft cannot transfer because Claritysoft stores engagement in its own activity log, not as subscriber-level metrics. If the customer needs call or meeting history in Mailchimp, they must link a third-party task management tool or document contacts externally. This is disclosed during scoping.
Claritysoft
Custom Module
Mailchimp
None
lossyClaritysoft Custom Modules (available on Accelerator and Enterprise tiers) have no equivalent in Mailchimp. Custom Modules represent domain-specific data (Projects, Equipment, Subscriptions, Vehicles) that Mailchimp cannot store. We do not migrate Custom Module records. We flag the module schemas during discovery, note which modules contain data the customer considers critical, and encode selected fields as Mailchimp custom fields or tags if the customer chooses. Most Custom Module data cannot be meaningfully represented in Mailchimp's flat subscriber model.

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.
Claritysoft gotchas
API access gated behind tier — Professional users cannot export via API
1 million record limit on Enterprise tier is migration-critical for large datasets
API key inherits owner's permission scope — limited-user keys miss records
Workflow Date Triggers require Enterprise tier and do not migrate cleanly
Importing bad data is a known failure mode Claritysoft warns against
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 API availability check
We audit the Claritysoft account across tier (Professional/Accelerator/Enterprise), contact count, account count, lead count, opportunity count, custom field schemas, active workflows, and engagement volume. We confirm API availability (Accelerator or Enterprise required) and plan the extraction method accordingly. We also extract subscription status indicators (bounced, unsubscribed, no-email contacts) during this phase and estimate the active Mailchimp audience size for pricing confirmation.
Data profiling and cleanup
We run a data profiling pass that identifies duplicate email addresses (Mailchimp requires unique emails per audience), contacts missing required fields (email address is mandatory), malformed email formats, and inconsistent date formats in custom fields. Claritysoft's own documentation lists importing bad data as a top implementation failure. We flag duplicates for the customer to resolve before import, remove contacts with invalid emails from the active import list, and encode custom field values to match Mailchimp's supported field types. This pass typically surfaces 5-15% data quality issues in typical SMB datasets.
Mailchimp schema setup and suppression list import
We create the Mailchimp audience and configure the subscriber custom fields to match the Claritysoft custom field schema before any data import. Tags are created in Mailchimp based on the Claritysoft tag taxonomy. The suppression list (bounced and unsubscribed contacts from Claritysoft) is imported into Mailchimp as a non-subscribed audience segment to protect deliverability and prevent re-sending to unsubscribed contacts. Domain authentication (SPF and DKIM) is coordinated with the customer's IT team during this phase per Mailchimp's migration checklist.
Contact and account encoding migration
We migrate Claritysoft Contacts to Mailchimp Audience Members in dependency order: active subscribed contacts first, then contacts with no recorded consent (as unsubscribed). Account names are encoded as tags or custom fields per the scoping decision. Custom fields are mapped field-by-field to Mailchimp subscriber fields. Tags are applied during import. We use the Mailchimp API with batch operations and exponential backoff for large imports. Each batch is reconciled against the source record count before the next batch begins.
Validation and delta reconciliation
We run a post-migration validation that compares the Mailchimp audience member count and email list against the Claritysoft source contact count, flagging any discrepancies. We spot-check 25-50 records for field-level accuracy (name, email, custom fields, tags). We verify that the suppression list was imported correctly by confirming bounced and unsubscribed contacts cannot be found in the subscribed audience. The customer reviews the validation report and approves before cutover.
Cutover and Workflow inventory handoff
We freeze Claritysoft writes during cutover and run a final delta migration of any contacts modified during the migration window. The customer confirms Mailchimp as the active sending platform. We deliver the Claritysoft Workflow inventory document listing every active automation with trigger conditions, actions, and recommended Mailchimp Customer Journey Builder equivalents. We do not rebuild automations in Mailchimp; that work is handled by the customer's marketing team. We support a three-day hypercare window for reconciliation issues and deliverability questions.
