Overview

What this migration involves

Moving from WORKetc to Mailchimp is a contact-focused migration, not a full CRM replacement. WORKetc bundles CRM, project management, and billing under one flat-rate subscription; Mailchimp is an email marketing and audience platform with CRM-adjacent contact features (audiences, tags, merge fields, basic segmentation). The only meaningful data overlap is Contacts, Companies, Leads, and Custom Fields — everything else in WORKetc (Deals, Projects, Tickets, Invoices, Knowledge Base, Workflows) has no Mailchimp equivalent and migrates as reference data or a separate CSV export. We extract via WORKetc's SOAP API or CSV UI export, deduplicate by email address (Mailchimp's primary key), map lifecycle stages to tags and custom merge fields, and validate against Mailchimp's audience size limits before cutover. Workflows, automations, and billing records do not migrate; we deliver a written reference document for the customer's admin.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

WORKetc logo

WORKetc

What's pushing teams away

  • Teams outgrow the platform as they scale — one reviewer noted the product worked initially but they quickly outgrew it.
  • Email integration limitations frustrate users who rely on direct synchronization with third-party email services.
  • Bugs and difficulty customizing the platform appear in negative reviews, particularly around early use periods.
  • The $78+ flat rate becomes expensive per-user as headcount grows beyond the included seats on Starter.
  • Some users report that the interface feels less polished than newer CRM competitors entering the market.

Mailchimp

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 WORKetc objects map to Mailchimp

Each row shows how a WORKetc 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.

WORKetc

Contact

maps to

Mailchimp

Audience Member

1:1
Fully supported

WORKetc Contact records map to Mailchimp Audience members. The Contact's email address is the Mailchimp primary key and dedupe field; we deduplicate on email during the transform phase before any import. Standard fields (First Name, Last Name, Phone, Address) map to Mailchimp's standard merge fields (FNAME, LNAME, PHONE, ADDRESS). The Contact owner assignment does not map — Mailchimp does not have a User-assignment model. Any duplicate email addresses across WORKetc Contacts are resolved by keeping the most recently updated record or merging into a single member with multiple WORKetc source tags.

WORKetc

Company

maps to

Mailchimp

Audience Member (company merge field)

1:1
Fully supported

WORKetc Company records are parent entities linked to multiple Contacts. Since Mailchimp does not have a Company or Account object, we flatten company data into the Contact-level mapping: the Company name becomes the COMPANY merge field on the linked Audience Member, and the Company phone and address append to the member's address data. If a Contact has no individual address but the parent Company does, we promote the Company address. Company-level custom fields migrate as additional merge fields on the member.

WORKetc

Lead

maps to

Mailchimp

Audience Member (segmented by lifecycle)

1:1
Fully supported

WORKetc Lead records map to Mailchimp Audience members, typically placed in a 'New Leads' segment or tagged with the WORKetc lead status value. We preserve the Lead's source, status, and conversion flag as Mailchimp tags (e.g., tag: lead_source=Gallery, tag: status=qualified). If the Lead converted to a Contact in WORKetc, the Contact import takes precedence to avoid duplicate records. We do not migrate unconverted Leads that have no email address — Mailchimp requires an email address for Audience members.

WORKetc

Custom Field

maps to

Mailchimp

Merge Field

lossy
Fully supported

WORKetc custom field definitions and values on Contact, Company, and Lead records map to Mailchimp Merge Fields within the target Audience. We map WORKetc field types to Mailchimp merge field types: text fields to TEXT, date fields to DATE, number fields to NUMBER, and dropdown/multi-select fields to either RADIO or CHECKBOX depending on single versus multi-select. Mailchimp allows up to 40 merge fields per Audience; we flag any migration exceeding this limit and prioritize the most business-critical fields.

WORKetc

Contractor (user type)

maps to

Mailchimp

Audience Member (tagged)

1:1
Fully supported

WORKetc distinguishes between full Users and Contractor Portal users with different permission scopes. Contractor records without standard email addresses may not be importable to Mailchimp without a valid email. We flag any Contractor records missing an email address and ask the customer whether to exclude them or supply a placeholder email for migration. Contractors who do migrate receive a CONTRACTOR tag in Mailchimp. This separation matters for GDPR and marketing consent contexts.

WORKetc

Deal

maps to

Mailchimp

Reference export (CSV)

1:1
Fully supported

WORKetc Deals map to Mailchimp as a reference CSV export rather than a live object. Mailchimp has no deal or opportunity tracking. We export Deal records (name, amount, stage, associated Contact, close date) as a separate CSV file delivered alongside the Audience migration. The customer uses this for offline reference or imports it into a separate CRM if needed. Deal stage pipeline names are exported as tags that can be applied to the related Contact if the customer wants to preserve deal context in Mailchimp.

WORKetc

Project

maps to

Mailchimp

Reference export (CSV)

1:1
Fully supported

WORKetc Projects with their Types, Stages, and weighted progress values have no Mailchimp equivalent. We export Project records as a separate CSV reference file including Project name, stage, progress percentage, associated Company, and associated Contacts. The Project Types and Stages weighted progress system (where each stage carries a custom percentage weight rather than a simple task-completion ratio) is exported with full stage configuration as metadata so the customer can reconstruct progress logic in their project management tool of choice.

WORKetc

Ticket (Support Case)

maps to

Mailchimp

Reference export (CSV)

1:1
Fully supported

WORKetc support tickets with conversation threads and attachment references export as a separate CSV. Mailchimp does not have a support case or helpdesk object. We export ticket headers (subject, status, priority, linked Contact, linked Company, created date) and deliver the conversation thread content as a separate structured file. The customer admin can import ticket reference data into their helpdesk platform or keep it as an offline archive. Attachment binary files are not migrated unless the destination Mailchimp account has the Content Studio add-on.

WORKetc

Workflow

maps to

Mailchimp

Written inventory (no code migration)

1:1
Fully supported

WORKetc Workflow rules and automation triggers are not exposed via API and cannot be programmatically extracted. We do not migrate workflows. We deliver a written inventory of every active WORKetc Workflow describing its trigger conditions, actions, and object scope, so the customer's admin can reconstruct the logic in Mailchimp's Customer Journeys or in a dedicated automation tool post-migration. The customer is responsible for rebuilding workflows in Mailchimp Customer Journeys, which uses a different trigger-action model.

Pair-specific challenges

  • WORKetc Starter tier excludes Open API access entirely

    The Open API module is not available on WORKetc Starter ($78/month). Teams on Starter cannot export data programmatically via SOAP or REST. We work around this by using CSV exports from the WORKetc UI for all Starter-tier migrations, which limits the fields available for export compared to the SOAP API. If the customer is on Starter and needs custom field data, the export must be done manually per object type from the WORKetc UI and uploaded to our migration environment. We verify the WORKetc tier and API access level during discovery before scoping the migration approach.

  • Mailchimp has strict audience size limits by pricing tier

    Mailchimp enforces contact limits per tier: Free up to 500, Standard tiers range from 500 to 100,000+ based on selected plan. Exceeding the limit without upgrading results in account suspension or send restrictions. During WORKetc contact audit, we calculate the total unique email addresses across Contacts, Leads, and Contractor records and compare against the customer's intended Mailchimp tier. We flag any overage before migration begins and recommend a tier upgrade or a contact cleanup to avoid account risk post-migration.

  • Mailchimp uses email as the primary dedupe key

    WORKetc Contacts, Leads, and Contractor records may share email addresses (e.g., a Contact record and a Lead record with the same email from a data entry error). Mailchimp requires a unique email address per Audience member — duplicate emails are rejected or merged silently depending on the import method. We run email deduplication during the transform phase, applying a customer-specified rule (keep most recent, keep with most custom field data, or merge into one record with multiple tags). We surface the deduplication report to the customer for approval before the Audience import runs.

  • WORKetc lifecycle stage and custom field data requires merge field pre-creation in Mailchimp

    WORKetc tracks lifecycle stages on Contacts and Leads, plus custom fields defined across objects. Mailchimp Audience members do not have a native lifecycle stage field — this data must exist as either a Tag or a Merge Field. We cannot import data into a Mailchimp Merge Field that does not already exist in the Audience schema. During scoping, we enumerate every WORKetc lifecycle stage and custom field value that needs to land in Mailchimp, then pre-create the corresponding Merge Fields (up to Mailchimp's 40-field limit) in the target Audience before the migration begins. Merge field type mapping (text, number, date, dropdown) must match the data format or the import rejects individual records.

  • Contractor portal users may lack valid email addresses

    WORKetc Contractor Portal users are a separate identity class from full Users, and some may have placeholder or internal email addresses rather than personal addresses. Mailchimp requires a valid, deliverable email address for every Audience member — invalid formats or role-based addresses (info@, support@, noreply@) may cause bounces that damage deliverability reputation. We flag Contractor records with non-personal email domains during audit and exclude them from the Audience migration unless the customer explicitly approves import with a note to verify deliverability. We deliver excluded Contractor records in a separate CSV for the customer's records.

Migration approach

Six steps for a successful WORKetc to Mailchimp data migration

  1. Discovery and tier audit

    We audit the WORKetc account across tier (Starter/Team/Foundations/Enterprise), active objects, and API access. We enumerate all Contacts, Companies, Leads, and Contractor records with email addresses, identify custom field definitions per object, and assess the total unique email count against Mailchimp tier limits. If the customer is on Starter, we confirm whether UI CSV exports cover all needed fields or whether an upgrade to a tier with API access is warranted for the migration. We also identify any Contractor records with non-standard email addresses and flag them for resolution. The discovery output is a written migration scope, an audience size assessment, and a merge field creation list for the customer to pre-provision in Mailchimp before the migration date.

  2. Data extraction and deduplication

    We extract contact records from WORKetc via SOAP API (Team tier and above) or CSV UI export (Starter tier). For API-based extraction, we introspect the WSDL for available methods, then pull Contact, Company, Lead, and Contractor records with all standard and custom fields. We resolve the parent-Company relationship for each Contact during extraction. In the transform layer, we run email deduplication using the customer's chosen rule (most recent record wins, or merge with tag), generate a deduplication report showing how many duplicates were resolved, and produce the full contact dataset in Mailchimp-compatible JSON for the API import or CSV for the bulk import path.

  3. Merge field pre-creation in Mailchimp

    Before any Audience import, the customer pre-creates the required Merge Fields in their Mailchimp Audience settings based on our merge field creation list from discovery. This includes mapping each WORKetc custom field to a named Merge Field (max 40 per Audience) with the correct type (TEXT, NUMBER, DATE, RADIO, CHECKBOX). We provide the exact field names, types, and descriptions in a setup checklist. If the count of required custom fields exceeds 40, we prioritize the highest-business-value fields and flag the remainder for post-migration manual entry or a secondary Audience.

  4. Sandbox import and validation

    We run a test import into a Mailchimp test Audience (or a new audience used as a staging environment) with a representative sample of 10-20% of the full contact set. We validate: merge fields populate correctly, tags apply from WORKetc lifecycle stages and lead sources, duplicate handling produces the expected member count, and addresses format correctly in Mailchimp's standard and non-US address formats. The customer reviews the sandbox Audience and confirms the mapping before we proceed to the production Audience. Any merge field corrections, tag naming changes, or dedupe rule adjustments happen at this stage.

  5. Production Audience migration and reference file delivery

    We migrate the full contact dataset to the production Mailchimp Audience using the validated mapping from sandbox. We use Mailchimp's batch API for large imports (over 5,000 members) with rate-limit handling and chunking to stay within the 100-concurrent-requests and 10-requests-per-second API limits. Concurrently, we generate and deliver the reference CSV files: Deals, Projects, Tickets, and Invoices as separate structured exports. We deliver the Workflow and Automation inventory document describing each WORKetc workflow's trigger, conditions, and actions for the admin to rebuild in Mailchimp Customer Journeys.

  6. Cutover, opt-in validation, and deliverability handoff

    We verify the final Audience member count against the WORKetc audit total and reconcile any discrepancies. We check that bounced and unsubscribed addresses from WORKetc are imported as suppressed contacts in Mailchimp (not active members) to protect deliverability. We validate Mailchimp domain authentication (SPF and DKIM) is in place for the sending domain. We deliver the migration summary report including member count, merge field coverage, tags applied, and the reference file inventory. We do not handle post-migration Customer Journey rebuild or ongoing email campaign setup; that is the customer's admin scope.
