Overview
Moving from m-savvy to Mailchimp is a narrowing migration: m-savvy is a full CRM with Contacts, Accounts, Deals, Leads, Activities, and Custom Objects; Mailchimp is an email marketing platform built around Audiences, Members, Campaigns, Tags, and Groups. We migrate the Contact and Company records that map directly to Mailchimp Members and Audience groups, preserving m-savvy lifecycle stage and owner assignments as tags that drive segmentation in Mailchimp. Deals, Leads, Activities, Custom Objects, and Attachments have no Mailchimp equivalents and are excluded from the migration scope; we deliver a written inventory of every excluded object with record counts so the customer admin can decide what to rebuild manually or in a supplemental tool. Workflows, automations, and sequences do not migrate as code. Mailchimp's text merge fields are capped at 255 characters, so long-text fields from m-savvy require truncation or splitting across multiple tags.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a m-savvy 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.
m-savvy
Contact
Mailchimp
Member
1:1m-savvy Contacts map directly to Mailchimp Members within a designated Audience. We map First Name, Last Name, Email, Phone, Address fields, and lifecycle stage to Mailchimp tags for segmentation. Opt-in status in m-savvy maps to Member Status (subscribed, unsubscribed, pending). Owner assignment from m-savvy maps to a tag or a Mailchimp Merge Field (OWNER) so campaigns can be attributed to the original owner. Email addresses are used as the dedupe key on import to prevent duplicate Members.
m-savvy
Account (Company)
Mailchimp
Group or Merge Field
lossym-savvy Account records have no direct Mailchimp equivalent. We map Account Name to a free-text Merge Field (COMPANY) and Account ID to a hidden tag for cross-reference. If the customer wants Account-level segmentation in Mailchimp, we create Groups for each Account and assign Members to their corresponding Group via the Mailchimp API. Industry, size, and billing address fields map to additional Merge Fields or remain as tags if no equivalent exists in the Audience schema.
m-savvy
Deal
Mailchimp
Not migrated
lossym-savvy Deals (pipeline opportunities with stage, amount, close date, probability) have no Mailchimp equivalent. Mailchimp is an email marketing platform and does not have an Opportunity or pipeline object. We export Deal records as a CSV during migration discovery and flag them for the customer admin to evaluate in a supplemental CRM, a spreadsheet, or a business intelligence tool. We do not create placeholder records in Mailchimp.
m-savvy
Lead
Mailchimp
Member
1:manym-savvy Leads are distinct from Contacts in the source data model. We merge Lead records into the same Mailchimp Audience as Contacts, mapping lead source and lead status to tags (LEAD_SOURCE, LEAD_STATUS) and preserving any lead score as a numeric Merge Field. Duplicate email addresses between Leads and Contacts are resolved using the email dedupe key: if a Lead email matches an existing Member, we update the Member record with Lead tags rather than creating a second Member.
m-savvy
Activity (Email, Call, Meeting, Task)
Mailchimp
Not migrated
lossym-savvy Activity records (emails, calls, meetings, tasks with timestamps, dispositions, and notes) have no equivalent in Mailchimp. Mailchimp tracks aggregate open and click data per Member but does not maintain a per-interaction activity log. We export Activity records as a timestamped CSV keyed by Contact ID so the customer can import historical activity into a separate analytics tool if needed. The import does not create entries in Mailchimp.
m-savvy
Custom Object
Mailchimp
Not migrated
lossym-savvy Custom Objects require live-org API discovery because m-savvy does not publish a public schema reference. We enumerate Custom Object types and their field definitions during the discovery phase and share the schema map with the customer. Since Mailchimp has no custom object support, we evaluate each custom object field individually: fields that map to Member properties (text, date, number) are promoted to Merge Fields or tags; fields that require relational context (lookups, roll-ups) cannot be represented in Mailchimp and are excluded with a count flagged in the handoff inventory.
m-savvy
Attachment
Mailchimp
Not migrated
lossym-savvy Attachments are stored separately from record data via file API endpoints. Mailchimp does not support file attachments on Member records. We download all attachments during the source export pass and store them in our staging environment. We deliver the attachment package as a named folder tree keyed by Contact ID and Account ID. The customer admin can host files separately or evaluate a document management integration.
m-savvy
Pipeline and Pipeline Stage
Mailchimp
Not migrated
lossym-savvy Pipeline definitions and stage names are read from the schema during discovery. Mailchimp does not have a pipeline concept. We document the pipeline structure (stage names, order, probability percentages) in the migration handoff inventory so the customer can decide whether to implement pipeline tracking in a supplemental CRM or project management tool post-migration.

Migration approach
Discovery and contact audit
We query the m-savvy API to enumerate all record types in the org, including custom objects discovered via live-org inspection. We pull record counts for Contacts, Accounts, Leads, Deals, Activities, and any custom objects. We identify the customer's m-savvy plan tier to confirm API export limits and flag any data that may be inaccessible on the current plan. We export a suppression-ready list of all unsubscribed and bounced contacts from m-savvy's contact status flags. The discovery output is a written scope document with record counts, schema summary, and a data-cleanup recommendation.
Audience setup and merge field configuration
We create the target Mailchimp Audience and configure Merge Fields that map to m-savvy source fields. We match field types: text fields to text merge fields, dates to date merge fields, numeric fields to number merge fields, and multi-value fields to groups or tags. We set up Groups for Account segmentation if the customer requests Account-level audience splits. Merge Fields are deployed before Member import so the dedupe and mapping process can reference them at migration time.
Suppression list import
We import the m-savvy unsubscribed and bounced contact list into Mailchimp's Suppression List for the target Audience before any active Members are imported. This step must complete before the Member import phase begins to prevent previously unsubscribed contacts from being re-activated. We also import contacts with a bounced email status to the bounce suppression list. Suppression import uses Mailchimp's bulk add-to-suppression-list endpoint with batch chunking to handle large lists.
Contact and Account migration
We migrate m-savvy Contacts and Leads in a single pass, merging Leads into the same Audience as Contacts using email address as the dedupe key. We apply the lifecycle stage split (Lead records tagged LEAD_SOURCE and LEAD_STATUS; Contacts tagged with their original m-savvy lifecycle stage and owner assignment). Account data is mapped to the COMPANY merge field and Account ID to a reference tag. We run a reconciliation count comparing imported Member total to the source contact total before marking this phase complete.
Engagement and attachment handoff
We export historical activity records (emails, calls, meetings, tasks) as a timestamped CSV keyed by Contact ID for the customer's manual import into an analytics tool. We download all file attachments from m-savvy's file API endpoints, organize them in a folder tree keyed by Contact and Account ID, and package them for delivery. We do not upload attachments to Mailchimp because Mailchimp does not support file attachments on Member records.
Handoff inventory and cleanup recommendation
We deliver a written migration handoff document that includes: record counts migrated and excluded per object type, the list of Mailchimp Merge Fields and Groups created with their source field mappings, a CSV of all excluded objects (Deals, Activities, Custom Objects, Attachments) with record counts, and a step-by-step guide for the customer's admin to import engagement history into Mailchimp manually. We do not rebuild m-savvy workflows or automations in Mailchimp as part of the migration scope.
