Overview
Migrating from Salesboom to Mailchimp is a shape-changing move: Salesboom is a full CRM with Leads, Accounts, Contacts, Opportunities, Cases, and ERP add-ons; Mailchimp is an email marketing platform built around Audiences, Contacts, Tags, Segments, and Campaigns. The migration centers on the Contact and Lead records that carry email addresses, which map to Mailchimp subscribers. Custom fields from Salesboom become Mailchimp merge fields or Tags depending on data type. Opportunities, Cases, ERP module records (Accounts Payable, HR, Payroll, PTO), and Workflow Automation do not have Mailchimp equivalents; we document these in a written inventory for your admin to address outside the migration scope. We use Mailchimp's REST API with batch upsert to handle subscriber creation and update in chunks, and we preserve the Contact-to-Account relationship as a Mailchimp Tag or a custom merge field so segmentation by company remains possible.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Salesboom 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.
Salesboom
Contact
Mailchimp
Audience Member (Subscriber)
1:1Salesboom Contacts map directly to Mailchimp Audience members via email address as the dedupe key. Standard Contact fields (First Name, Last Name, Email, Phone, Mailing Address) map to Mailchimp FNAME, LNAME, EMAIL, PHONE, and address merge fields. We use Mailchimp's batch upsert endpoint (PUT /lists/{list_id}/members/{subscriber_hash}) with status=subscribed to create or update subscribers without creating duplicates. The Contact-to-Account association migrates as a custom merge field (COMPANY_NAME) and as a Mailchimp Tag derived from the related Salesboom Account name, preserving the ability to segment by company without a native parent-child relationship.
Salesboom
Lead
Mailchimp
Audience Member (Subscriber)
1:manySalesboom Leads map to the same Mailchimp Audience as Contacts. We evaluate the Lead status field to determine segmentation: new or open Leads receive a Lead tag; qualified or converted Leads receive a Qualified_Lead tag. The original Salesboom Lead status value is stored in a custom merge field (SB_LEAD_STAT) for audit. If the customer runs multiple Salesboom pipelines (Marketing vs. Sales), we can split Leads into separate Mailchimp Audiences by pipeline during migration to match downstream segmentation strategy.
Salesboom
Account
Mailchimp
Tag + Merge Field (COMPANY_NAME)
1:1Salesboom Account records are not a native Mailchimp object type. Account names and Account IDs migrate as a Mailchimp Tag per unique Account (tag name = Account Name, tag source = Mailchimp) and as a custom merge field COMPANY_NAME on the subscriber record. This preserves the ability to filter subscribers by organization in Mailchimp Segments. If the customer has fewer than 50 unique Accounts, we recommend creating one tag per Account. If there are more than 50, we recommend mapping to the COMPANY_NAME merge field only and using segment filters on that field.
Salesboom
Custom Fields (Contact and Lead level)
Mailchimp
Merge Fields (Merge Tags) or Tags
lossySalesboom custom fields on Contact and Lead migrate to Mailchimp merge fields or tags depending on data type. Text, number, and date fields map to Mailchimp merge fields (type: text, number, or date). Multi-select picklist and checkbox fields map to Mailchimp Tags. Note that Mailchimp Essentials supports up to 40 merge fields per audience, Standard supports 80, and Premium supports unlimited. We audit the total count of active custom fields per object during scoping and recommend an Audience split or selective field migration if the count exceeds the destination tier's limit. Custom fields on non-contact objects (Opportunity, Case, ERP modules) are documented but have no Mailchimp target and are excluded from the migration.
Salesboom
Opportunity
Mailchimp
None (excluded)
lossySalesboom Opportunities represent pipeline deals with stage, amount, close date, and probability. Mailchimp does not have an Opportunity object. We exclude Opportunities from the migration scope. We deliver a written inventory of all active Opportunities at migration time (exported as a CSV from Salesboom) including stage, amount, close date, owner, and related Account and Contact names. The customer's admin uses this to rebuild a pipeline tracking approach in Mailchimp (Customer Journey with manual status updates, or a third-party CRM if pipeline management is still required).
Salesboom
Case
Mailchimp
None (excluded)
lossySalesboom Cases are ticket-style support records with status, priority, origin, and resolution fields. Mailchimp does not have a case or ticket management module. We exclude Cases from the migration scope. Support-related contact history (resolved cases, open case counts) can be preserved as Mailchimp tags on the Contact record if the customer requests it, but this is an opt-in configuration. We deliver a Case inventory CSV as part of the handoff package.
Salesboom
ERP Modules (AP, HR, Payroll, PTO)
Mailchimp
None (excluded)
lossySalesboom ERP add-on modules (Accounts Payable, HR Policy Tracking, Payroll, PTO Management, Expense Tracking) each cost $10/user/month and have distinct transactional schemas unrelated to email marketing. These modules have no Mailchimp equivalent and are excluded from the migration entirely. We confirm whether the customer has licensed any ERP modules during scoping and flag them in the pre-migration audit so that no one expects this data to appear in Mailchimp post-migration. Transactional ERP data requires a separate migration to an accounting or HRIS platform if retained.
Salesboom
Workflow Automation
Mailchimp
None (excluded)
lossySalesboom Workflow & Business Process Automation rules (available on Professional and Enterprise tiers) define automatic lead routing, task assignment, email triggers, and field updates based on record criteria. Mailchimp Customer Journey automations are email-triggered and campaign-focused; they do not replicate CRM workflow logic. We do not migrate Workflows as code. We deliver a written inventory of every active Salesboom workflow rule including its trigger object, conditions, actions, and recommended Mailchimp Customer Journey equivalent (or a note that no equivalent exists in Mailchimp). The customer's admin rebuilds these in Mailchimp post-migration.

Migration approach
Pre-migration audit and scope confirmation
We audit the Salesboom source environment across all tiers (Team/Professional/Enterprise), extracting record counts for Contacts, Leads, Accounts, Opportunities, Cases, and any licensed ERP modules. We audit custom field counts per object, active workflow rules, and the current Mailchimp sync status if the native connector is active. We also query the destination Mailchimp audience to detect existing subscribers and their status values. The output is a written migration scope document confirming record counts, merge field mapping requirements, any tier upgrade needed in Mailchimp, and which objects are excluded from migration.
Merge field and tag taxonomy design
We design the Mailchimp merge field schema based on the Salesboom custom field audit. Text, number, date, and phone fields become Mailchimp merge tags (MERGE0 through MERGE{N}). Multi-select picklist and checkbox fields become Mailchimp Tags with one tag per option value. We design the tag taxonomy for Account names and any classification tags (Lead source, pipeline, region). If the Mailchimp account is on Essentials or Standard and the merge field count exceeds the tier limit, we present a field selection decision to the customer before creating any merge fields in Mailchimp.
Data extraction and deduplication from Salesboom
We extract Contacts, Leads, and Accounts from Salesboom via the JSON API at secure4.salesboom.com/jsonapi/. We use email address as the primary dedupe key. For each Contact or Lead with a related Account, we resolve the Account name and include it in the merge field and tag data. We flag records with missing email addresses as a separate reconciliation queue; these records cannot migrate to Mailchimp without an email address and are excluded unless the customer can supply one.
Mailchimp audience creation and bulk subscriber upsert
We create the destination Mailchimp audience (or audiences if the customer requests a multi-audience split by Salesboom pipeline or Lead source) and configure all merge fields before any subscriber data is loaded. We then use Mailchimp's batch upsert endpoint (PUT /lists/{list_id}/members/{subscriber_hash}) in chunks of up to 500 records per batch to create or update subscribers. We set status to subscribed for new records and preserve the existing status for records already present in the audience. Owner reconciliation (Hubspot Owner to Mailchimp tag or a designated Owner merge field) happens during this step.
Tag application for Account segmentation
After the subscriber bulk upsert completes, we apply Account-derived tags to all subscribers that have a related Salesboom Account. For audiences with fewer than 50 unique Accounts, we create one tag per Account. For larger Account counts, we rely on the COMPANY_NAME merge field for segmentation and skip bulk tag creation to avoid tag-spam. We also apply any classification tags (Lead source, pipeline stage, region) identified during the taxonomy design step.
Cutover, excluded-data handoff, and automation rebuild inventory
We freeze writes to Salesboom at cutover, run a final delta extraction of any records modified during the migration window, upsert the delta to Mailchimp, then disable the Salesboom-Mailchimp sync connector (if applicable) and declare Mailchimp the primary marketing platform. We deliver the excluded-data CSV package (Opportunities, Cases, ERP records), the workflow automation inventory document, and the full field mapping reference to the customer's admin team. We do not rebuild Salesboom Workflows as Mailchimp Customer Journeys inside the migration scope; that is a separate engagement.
