Overview

What this migration involves

ConSol CM stores customer data across contacts, companies, service tickets, and custom properties with owner assignments and timestamp history. Mailchimp organizes everything as contacts within one or more audiences, with tags, merge fields, and signup sources as the primary organizing metadata. The migration extracts ConSol contacts and companies, flattens the relationship model into Mailchimp's contact-centric structure, and recreates relevant custom properties as Mailchimp merge fields or contact tags. ConSol service tickets and case records have no direct Mailchimp equivalent — we surface them as contact-level tags and custom fields so support history is accessible on each contact record. Automations, workflows, and service-level agreements from ConSol do not transfer; they must be rebuilt in Mailchimp's automation builder. We sequence the migration using ConSol's API export, transform records to Mailchimp's import format, and run a sample migration with field-level diff before committing the full audience.

ConSol

What's pushing teams away

  • Limited integration with external CRM systems noted as a frustration in G2 reviews, with users unable to connect ConSol CM to their primary customer platforms.
  • Complex feature set and steep learning curve reported in G2 feedback, with users feeling overwhelmed by information density during onboarding.
  • Perpetual licensing and enterprise pricing structure makes the platform costly for smaller organizations evaluating alternatives.
  • Vendor lock-in concerns with proprietary German-developed platform motivating organizations to evaluate international alternatives with broader ecosystem support.

What's pulling them in

  • Generous free tier with up to 500 contacts allows small teams to validate email marketing before committing to a paid plan.
  • Intuitive drag-and-drop email builder and 130+ templates let non-technical users produce professional campaigns without HTML or CSS knowledge.
  • 300+ native integrations, especially Canva and Shopify, make it easy to connect existing tools without custom development work.
  • Detailed open-rate, click-through, and campaign analytics give small businesses actionable insights without a dedicated marketing team.
  • One-platform consolidation of email campaigns, automations, landing pages, and ads reduces tool sprawl for lean marketing teams.

Object mapping

How ConSol objects map to Mailchimp

Each row shows how a ConSol 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.

ConSol

Contact

maps to

Mailchimp

Audience Contact

1:1
Fully supported

ConSol contacts map directly to Mailchimp contacts within the target audience. The contact's email address becomes the Mailchimp email address — this is the unique identifier. ConSol contact IDs are preserved as a merge field for traceability and delta-run de-duplication.

ConSol

Company

maps to

Mailchimp

Merge Field + Tag

1:1
Fully supported

ConSol company records have no direct Mailchimp equivalent. Company name, industry, and domain map to Mailchimp merge fields (COMPANY, INDUSTRY, WEBSITE). The primary company association per contact is preserved; secondary companies surface as tags in 'Company: [Name]' format.

ConSol

Service Ticket / Case

maps to

Mailchimp

Contact Tag + Merge Field

1:1
Fully supported

ConSol service tickets have no Mailchimp equivalent — Mailchimp tracks email engagement but not case resolution. We create a 'Ticket History' merge field and tag each contact with 'Ticket: [ID] - [Status]' for quick reference. Ticket subjects become custom merge fields; ticket counts per contact are summarized as a numeric merge field.

ConSol

Contact Custom Field

maps to

Mailchimp

Merge Field

1:1
Fully supported

ConSol custom fields on contacts (such as Contract_Type, Support_Tier, or SLA_Expiry) are recreated as Mailchimp merge fields. Field types are mapped: text to text, date to date, number to number, and pick-lists to dropdown merge fields with the original values as options.

ConSol

Company Custom Field

maps to

Mailchimp

Merge Field

1:1
Fully supported

ConSol custom fields on companies (such as Contract_Value, Onboarding_Date, or Account_Manager) migrate as Mailchimp merge fields attached to contacts. We preserve the company-level context by prefixing the merge field name with 'Company_' to distinguish from contact-level fields.

ConSol

Contact Tag / Category

maps to

Mailchimp

Mailchimp Tag

1:1
Fully supported

ConSol contact categories and tags map directly to Mailchimp tags. Tag names are preserved exactly as they appear in ConSol. If a contact has multiple categories, each becomes a separate Mailchimp tag — no tag hierarchy in Mailchimp means multi-level ConSol categories are flattened to hyphenated strings.

ConSol

Contact Owner / Agent

maps to

Mailchimp

Signup Source + Merge Field

1:1
Fully supported

ConSol assigns contacts and tickets to named agents. Mailchimp has no per-contact owner concept. We capture the original ConSol owner as a 'Original_Agent' merge field and use the owner as a signup source attribution tag — so campaigns can be filtered by original ConSol agent if needed.

ConSol

Ticket Email Thread

maps to

Mailchimp

Activity Note

1:1
Fully supported

ConSol email threads attached to service tickets record the full customer conversation. Mailchimp has no thread storage — we preserve thread metadata (message count, last update date, assigned agent) as merge fields on the contact. Full thread content is exported as a JSON attachment for audit purposes.

ConSol

Document / Attachment

maps to

Mailchimp

Not Migrated

1:1
Fully supported

ConSol documents linked to contacts or tickets (contracts, onboarding PDFs, support attachments) have no Mailchimp equivalent. We export the file list and storage paths as a reference manifest. Files must be migrated separately to a document management system or linked from Mailchimp contact profiles via external URLs.

ConSol

Contact Email Opt-In

maps to

Mailchimp

Audience Subscription Status

1:1
Fully supported

ConSol stores contact communication preferences and email opt-in flags. These map to Mailchimp's subscribed / unsubscribed / non-subscribed status. Contacts with an active email address in ConSol land as 'subscribed' unless explicitly unsubscribed — double opt-in status is preserved as a merge field.

ConSol

Multi-List / Multi-Company Setup

maps to

Mailchimp

Audience Split or Merge

1:1
Fully supported

ConSol organizations with multiple business units may have separate contact lists. We map these to either a single Mailchimp audience (with business-unit tags) or multiple audiences (one per ConSol list) based on your segmentation needs. Duplicate contacts across lists are merged with all tags applied.

ConSol

Ticket Status / Resolution

maps to

Mailchimp

Tag + Merge Field

1:1
Fully supported

ConSol ticket statuses (Open, In Progress, Pending Customer, Resolved, Closed) map to Mailchimp tags. We use a 'Ticket Status' merge field to store the current value and apply 'Ticket-[Status]' tags for segmentation. Historical status changes are preserved in the ticket metadata merge field.

Pair-specific challenges

  • ConSol service tickets have no Mailchimp equivalent — ticket history surfaces as tags, not case records

    ConSol CM's core object is the service ticket: it tracks request subject, status, priority, assigned agent, email threads, and SLA timers. Mailchimp has no ticket or case object — it tracks email campaign engagement (opens, clicks, unsubscribes) but not support request status. When migrating from ConSol to Mailchimp, all ticket records are surfaced as contact-level tags ('Ticket: [ID] - [Status]') and merge field metadata. If your team relies on ConSol ticket history for customer health scoring or support load reporting, that logic must be rebuilt in Mailchimp using the preserved merge field values or an external reporting layer.

  • ConSol's N:N contact-to-company model flattens to a single primary-company assignment in Mailchimp

    ConSol CM allows a contact to be associated with multiple companies simultaneously — a common pattern for enterprise accounts where a contact works across parent and subsidiary companies. Mailchimp contacts have no native company linkage; each contact record holds one set of company-related fields. We resolve this by assigning the most recently modified ConSol company as the primary (mapped to the COMPANY merge field) and applying additional company associations as tags in 'Company: [Name]' format. If your reporting depends on multi-company contact views, you will need to build Mailchimp segments using the tag data or export the full company-contact mapping for external analysis.

  • ConSol workflows and service automations do not migrate — escalation rules and SLA timers must be rebuilt in Mailchimp

    ConSol CM includes service request routing rules, escalation workflows, SLA timers, and auto-assignment logic based on ticket category and priority. Mailchimp automation is email-campaign-centric: it triggers on opens, clicks, purchases, or date-based conditions. There is no SLA timer, no queue-based routing, and no agent assignment concept in Mailchimp. The migration exports your ConSol workflow definitions as a reference document so your team can evaluate which rules can be approximated in Mailchimp's automation builder and which ConSol-specific logic is not translatable to an email marketing context.

  • ConSol document attachments do not migrate to Mailchimp — file storage paths are exported as a reference manifest

    ConSol stores documents linked to contacts and service tickets — contracts, signed agreements, support screenshots, and uploaded files are tracked in ConSol's document management layer. Mailchimp stores attachments as campaign assets (images in email templates) but has no per-contact document storage. We export the document metadata (file name, ConSol storage path, linked contact ID, linked ticket ID) as a JSON manifest. Files must be migrated separately to a document management system such as SharePoint, Google Drive, or a dedicated DMS, and linked from Mailchimp contact profiles via external URL fields if needed.

  • Mailchimp contact counts include unsubscribed contacts in billing — ConSol opted-out contacts must be suppressed

    Mailchimp billing is based on total contact count in an audience, including unsubscribed and non-subscribed contacts in most plan tiers. ConSol stores explicit opt-in and opt-out flags per contact. Before migration, we identify all ConSol contacts with an active opt-out or bounced-email status and import them as suppressed contacts in Mailchimp so they are not counted toward your plan limit. Contacts that were soft-bounced in ConSol are similarly suppressed in Mailchimp to protect deliverability metrics after migration.

Migration approach

Six steps for a successful ConSol to Mailchimp data migration

  1. Audit ConSol data model and export structure

    We connect to ConSol CM via API using scoped read access and document the full contact, company, ticket, and custom field schema. We identify all active and archived ticket records, contact tags, custom field definitions, and owner assignments. This audit produces a migration plan that identifies which ConSol objects will map to Mailchimp contacts, which will become merge fields or tags, and which have no Mailchimp equivalent and will be exported as reference data.

  2. Design Mailchimp audience schema and merge fields

    Based on the ConSol audit, we pre-create the Mailchimp audience structure: the primary audience, all required merge fields (text, date, number, dropdown), and the tag taxonomy. Merge field names follow ConSol's naming convention where practical. We confirm the audience setup with you before importing any data so the Mailchimp side is ready and validated.

  3. Resolve multi-company associations and suppress opt-outs

    ConSol contacts with multiple company associations are resolved to one primary company (most recently modified by default) with secondary companies as tags. All ConSol contacts with an opt-out flag, bounced email, or spam complaint are imported as suppressed contacts in Mailchimp so they are not counted toward billing and do not receive campaigns after migration. Bounced and invalid email addresses are similarly suppressed.

  4. Run sample migration with field-level diff

    A representative slice — typically 100–500 ConSol contacts spanning different ticket statuses, company types, and custom field values — migrates first. We generate a field-level diff comparing ConSol source values against the Mailchimp imported record so you can verify tag accuracy, merge field values, ticket metadata preservation, and subscription status. You sign off on the sample before the full migration commits.

  5. Execute full migration with delta pickup window

    The full ConSol contact and company set migrates to Mailchimp using the mapping validated in the sample. A delta pickup window (typically 24–48 hours) captures any ConSol records created or modified during the cutover window. All operations are logged in an audit trail. If reconciliation identifies record mismatches, one-click rollback reverts the Mailchimp audience to its pre-migration state.

Most ConSol-to-Mailchimp migrations complete within 24–72 hours for under 25,000 contacts. The planning and audience-design phase takes 3–5 business days before migration runs. Complex setups with extensive custom fields on ConSol tickets or multiple company associations per contact extend the timeline to 5–10 business days. The longest single step is typically the merge field design and value mapping for ConSol pick-list fields.
