Overview
Moving from Opal CRM to Mailchimp is a migration from a field-sales CRM to an email marketing platform, not a like-for-like replacement. Opal CRM organizes data around field-sales workflows: Leads tracked from capture through quotation, Sales Reps assigned to territories, and Tour Plans managing field itineraries. Mailchimp stores contacts in Audiences and does not have a native pipeline, quotation, or rep-assignment model. We migrate Leads to Mailchimp Contacts with standard and merge fields preserved, segment by any available pipeline stage or source data, and migrate basic email activity notes as contact notes. Tour Plans, Quotations, Sales Representative records, and role-based permissions have no Mailchimp equivalent; we document each as a manual-rebuild item in the handover notes. Automations and workflows in Opal CRM are not migrated as code. We extract what data is available from Opal CRM through manual export or direct database access since no public API is documented.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Opal 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.
Opal CRM
Lead
Mailchimp
Contact (Audience Member)
1:1Opal CRM Leads map to Mailchimp Contacts within a single Audience. Standard fields (first name, last name, email, phone) map to Mailchimp Merge Fields (FNAME, LNAME, EMAIL, PHONE). Any custom fields on the Lead object migrate as additional merge fields. We deduplicate by email address using Mailchimp's built-in hash-based deduping and flag any records with missing email as a manual-rebuild item.
Opal CRM
Company
Mailchimp
Merge Field or Tags
lossyOpal CRM Company records (if present alongside Leads) map to Mailchimp merge fields or tags on the Contact. We recommend a COMPANY merge field for the primary organization name. If companies have multiple associated contacts, we create tags per company name and apply them to all migrated contacts from that company for segmentation purposes.
Opal CRM
Sales Representative
Mailchimp
Tags (manual owner attribution)
lossyOpal CRM Sales Reps do not have a Mailchimp equivalent because Mailchimp has no user-assignment model for contacts. We capture the assigned Sales Rep name on each Lead as a tag (format: owner:{rep_name}) during migration. The customer's admin applies these tags manually or sets up a Mailchimp collaborator workflow if rep-based contact routing is required post-migration.
Opal CRM
Pipeline Stage
Mailchimp
Tags or Segments
lossyOpal CRM pipeline stages (Lead, Qualified, Proposal, Negotiation, Closed) do not map to Mailchimp objects because Mailchimp has no pipeline model. We capture the pipeline stage as a tag on each contact (format: stage:{stage_name}) and recommend the customer build Mailchimp Segments based on stage tags for targeted campaign routing. Stage order and probability do not migrate; these are documented for manual rebuild if needed.
Opal CRM
Activity: Email
Mailchimp
Contact Notes
1:1Opal CRM email activity logs migrate as notes on the corresponding Mailchimp Contact. Each email engagement becomes a note entry with the original timestamp, subject, and direction (sent/received). Mailchimp's contact timeline displays these as historical notes rather than a structured activity log.
Opal CRM
Activity: Call
Mailchimp
Contact Notes
1:1Opal CRM call logs migrate as notes on the corresponding Mailchimp Contact. We include call duration, disposition, and timestamp in the note body. Call recordings do not migrate; we flag this in the handover documentation for the customer's admin.
Opal CRM
Tour Plan
Mailchimp
Not Migrated (Documented)
1:1Opal CRM Tour Plans with itinerary dates, locations, and expense line items have no Mailchimp equivalent. We do not migrate Tour Plans as data records. We document the Tour Plan schema (fields present, record count) in the handover notes so the customer's admin can decide whether to export separately or rebuild using Mailchimp's customer journey automations with date-based triggers.
Opal CRM
Quotation
Mailchimp
Not Migrated (Documented)
1:1Opal CRM Quotations with line items and workflow approval state have no Mailchimp equivalent. Mailchimp is an email marketing platform and does not handle sales quoting, contract generation, or approval workflows. We document the Quotation schema (field count, workflow status values) in the handover notes. The customer rebuilds quotation workflows outside Mailchimp or exports quotation data to a spreadsheet.
Opal CRM
Custom Properties
Mailchimp
Merge Fields
lossyOpal CRM custom fields on Leads migrate to Mailchimp Merge Fields. We identify custom fields during discovery (the schema is not publicly documented, so we extract field names from the customer's manual export), create matching merge fields in the Mailchimp Audience before import, and map values during the CSV transformation. Merge field type (text, number, date, phone) is inferred from data values in the export.

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.
Opal CRM gotchas
No publicly documented API for bulk data export
Tour Plan expense data may flatten during export
Quotation workflow state is not a standard CRM field
Free tier limits and trial expiry not visible in export
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 export file request
We audit the customer's Opal CRM account by requesting a full data export. Since no API exists, we work with the customer to extract a manual CSV or database backup covering Leads, Companies, Activities (calls, emails), Tour Plans, and Quotations. We validate record counts against the Opal CRM UI, identify any custom fields present in the export, and confirm whether Sales Rep and pipeline stage data are included. The discovery output is a written scope confirming what records and fields will migrate and what will be documented as manual-rebuild items.
Audience and merge field setup in Mailchimp
We create the destination Mailchimp Audience and configure merge fields before any import. We map standard Opal CRM Lead fields (name, email, phone, company) to Mailchimp's FNAME, LNAME, EMAIL, and PHONE merge fields. Any custom fields from Opal CRM are created as additional merge fields with inferred types. We set up tags for pipeline stages, owner attribution, and any contact source channels present in the export.
Data extraction and transformation
We receive the Opal CRM export file (CSV or equivalent) and transform it into Mailchimp's import format. This includes splitting multi-value fields (such as phone numbers with multiple entries), standardizing date formats, resolving company names for the COMPANY merge field, and applying the pipeline stage tag logic. We deduplicate by email address using Mailchimp's hash and flag any records with missing or malformed email addresses for manual review.
Audience import and contact validation
We import the transformed contacts into the Mailchimp Audience using Mailchimp's documented import process, chunking large imports to avoid timeout errors. We generate a reconciliation report showing the number of records imported versus the number in the source export and call out any records skipped due to missing email, duplicates, or format errors. The customer reviews and approves the import before we proceed to activity and historical data.
Activity note migration and tag application
We migrate email and call activity from Opal CRM as notes on the corresponding Mailchimp Contact. For each activity record in the export, we locate the matching Contact by email address and append a timestamped note containing the activity details. We apply pipeline stage tags and owner tags to contacts based on the original Lead record values. Activity migration is completed after contact import so that parent-contact records exist before notes are attached.
Documentation handoff and Tour Plan/Quotation archive
We deliver a written inventory of all Opal CRM objects that did not migrate: Tour Plans, Quotations, Sales Rep roles, and custom workflows. This document includes record counts, field schemas, and recommended rebuild approaches in Mailchimp or an external tool. We do not rebuild automations or workflows as code; the customer's admin uses this inventory to recreate them in Mailchimp Customer Journeys or another chosen platform. We offer a one-week hypercare window for reconciliation questions.
