Overview
Migrating from CRM Runner to Mailchimp is a narrowing migration — you are extracting email marketing and contact data from an all-in-one field-service CRM and moving it into a platform focused specifically on email marketing, audience segmentation, and campaign automation. CRM Runner stores Contacts, Companies, Jobs, Team Members, Communications, and time tracking in a single platform with no documented API; Mailchimp is an audience-centric marketing platform with no native concept of Accounts, Opportunities, Work Orders, or employee records. We extract contacts and company associations through UI-based scoping, map Companies to Mailchimp tags and groups, and flag all other CRM Runner objects as outside Mailchimp's data model. The absence of a CRM Runner API means migration runs slower than API-based alternatives, but contacts, company names, tags, and custom field values under 255 characters migrate cleanly. Automations, communications history, and payment records do not have Mailchimp equivalents and are excluded from standard scope.
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 CRM Runner 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.
CRM Runner
Contact
Mailchimp
Audience Member
1:1CRM Runner Contact records map directly to Mailchimp Audience members. The email address is the required merge field; first name and last name map to FNAME and LNAME. Any CRM Runner custom fields on contacts with text values under 255 characters map to Mailchimp merge tags. Fields exceeding 255 characters are flagged and either truncated or moved to a separate notes document for manual review. We dedupe by email address during import and flag records with missing email addresses for the customer's review before insertion.
CRM Runner
Company
Mailchimp
Tag or Group
1:1CRM Runner Company records have no direct Mailchimp equivalent. We handle the contact-to-company relationship by creating a Mailchimp tag or group named after each Company record and applying it to all Audience members linked to that company in CRM Runner. The customer chooses tag or group strategy during scoping. Tags are simpler; groups enable group-level email suppression. We preserve the company name as the tag or group label and record the original CRM Runner company ID in a merge field crm_company_id__c for reconciliation.
CRM Runner
Jobs
Mailchimp
None
lossyCRM Runner Jobs (work orders, job status, location, assigned team members) have no Mailchimp equivalent. Job data does not migrate into the Mailchimp Audience. We extract the last job date, job status, and job location as optional merge fields on the Contact if the customer specifies this as a segmentation need, but the full Jobs object is excluded from standard scope. We recommend pairing the CRM migration with a dedicated field-service or project management tool for Jobs data.
CRM Runner
Team Members
Mailchimp
None
1:1CRM Runner Team Members (employee records with roles and permissions) do not map to Mailchimp contacts because they represent internal staff rather than marketing recipients. If the Team Member also has a Contact record in CRM Runner (e.g., the person is both an employee and a customer), we migrate that Contact but flag the Team Member record separately for the customer to decide whether to import as an Audience member. The permissions and role data from CRM Runner does not migrate to Mailchimp.
CRM Runner
Communications (Calls, SMS, Chat)
Mailchimp
None
lossyCRM Runner stores call logs, SMS threads, and in-app chat as discrete records attached to contacts or jobs. Mailchimp has no activity timeline equivalent — it only tracks email campaign engagement (opens, clicks, unsubscribes). We do not migrate communications history to Mailchimp. We do export the communications history as a separate JSON artifact for the customer's records, but this data set has no usable destination in Mailchimp and must be archived or moved to a separate system.
CRM Runner
Tasks
Mailchimp
None
1:1CRM Runner Tasks with due date, assignee, and status have no Mailchimp equivalent. Mailchimp does not support a task or to-do object. We do not migrate Tasks. If CRM Runner Tasks are linked to specific Contacts and the customer wants to preserve the task context, we export the task subject, due date, and status as a custom merge field on the Contact record during the Contact migration phase, accepting the loss of assignee and status fields.
CRM Runner
Custom Fields
Mailchimp
Merge Tags
lossyCRM Runner custom fields on Contacts map to Mailchimp merge tags with the 255-character limit enforced. Multi-select picklist fields from CRM Runner map to Mailchimp groups with each picklist value as a group option. Checkbox fields map to Mailchimp merge tags with 1/0 values. Date fields map to Mailchimp date merge tags. We flag any CRM Runner custom field exceeding the 255-character limit during scoping and present three options: truncate, export as a separate notes document, or drop the field entirely.
CRM Runner
Pipelines
Mailchimp
None
1:1CRM Runner deal pipeline stages (e.g., Prospect, Qualified, Proposal, Won, Lost) have no Mailchimp equivalent. Mailchimp is not a sales pipeline tool and does not track opportunity stage, deal value, or close probability. We do not migrate pipeline data. If the customer wants to use pipeline stage as a segmentation signal in Mailchimp, we can import the last-known pipeline stage as a tag or merge field on the Contact, but this is an informational label, not a functional pipeline.

Migration approach
Discovery and data audit
We audit the CRM Runner account through UI-based extraction, inventorying all Contacts (with email, phone, custom fields), Companies (with name and member list), any active CRM Runner automations, and custom field definitions. We check for contacts with missing or invalid email addresses, duplicate entries, and contacts added without confirmed opt-in. We also identify Jobs, Team Members, Tasks, and Communications records to confirm exclusion scope. The discovery output is a written scope document with record counts per object, a list of custom fields and their character lengths, and a decision item for the tag-versus-group company mapping strategy.
Mailchimp audience and merge tag setup
We create the Mailchimp Audience in the destination account and define merge tags corresponding to the CRM Runner custom fields that pass the 255-character check. Merge tags are created with the correct type — text, number, date, address, phone — matching the CRM Runner field type. We create tags or groups for the company mapping strategy chosen during scoping. We configure the audience settings including default from name, from email, and opt-in confirmation if the customer requests double opt-in. The audience is created before any data import begins so that the import process can write directly to a live audience.
Data cleanup and deduplication
We run deduplication against the CRM Runner contact list, merging records that share the same email address while preserving the most complete record set (preferring records with more custom field values populated). Records with missing email addresses are flagged in a separate queue for the customer to resolve or exclude. We standardize phone number formats and address fields to match Mailchimp's expected format. If any CRM Runner custom fields exceed 255 characters, we apply the truncation or exclusion decision agreed upon during discovery. The cleaned contact list is exported as a CSV package with merge tag labels matching the Mailchimp audience schema.
Company tagging and group assignment
We map each CRM Runner Company to its Mailchimp tag or group and produce an association table (contact ID to company ID to tag/group name). This table is applied during the import phase so that each contact receives the appropriate tag or group assignment at the moment of insert. If using groups, we create group categories and group options matching the company names. If using tags, we create simple string tags. The customer reviews a sample of 25-50 tagged contacts before we proceed to full import.
Audience import and validation
We import the contact CSV into the Mailchimp Audience using Mailchimp's standard import interface, chunking the file into batches of 5,000 records to stay within Mailchimp's import rate limits. After each batch, we validate the import count against the source record count. We spot-check 25-50 records for correct merge tag population, tag assignment, and email format. We also verify that the group or tag count matches the company-to-contact association table. Any records rejected during import (due to format errors or missing required fields) are collected, corrected, and reimported in a second pass.
Cutover, validation, and automation rebuild handoff
We freeze CRM Runner as the system of record once the Mailchimp audience is validated. We deliver the automation inventory document (written specifications for every CRM Runner automation) to the customer's team along with a Mailchimp Customer Journeys rebuild guide. We do not rebuild CRM Runner automations as Mailchimp Customer Journeys inside standard scope. We support a one-week hypercare window for reconciliation issues raised during the first campaign send. We do not provide post-migration admin support, training, or workflow rebuild as standard scope.
