Overview

What this migration involves

Moving from Lemon Tech to Mailchimp is a CRM-to-email-marketing-platform migration, not a CRM-to-CRM move. Lemon Tech organizes data around Entities, Matters, Contacts, and Users with a legal-practice data model; Mailchimp is structured around Audiences, Tags, Segments, and Campaigns with no native case or matter management. We extract contacts and company associations via Lemon Tech's built-in export tooling, map custom entity properties to Mailchimp merge fields, and use tags as the primary segmentation vehicle for data that has no direct equivalent in Mailchimp's flat contact model. Matters, billing records, and SQL Wrapper data do not migrate to Mailchimp because the platform has no equivalent object; we deliver a written record of these for the customer's admin to evaluate for a parallel CRM replacement. Automations, customer journeys, and signup forms do not migrate as code and require rebuild in Mailchimp.

Why teams make this switch

Two sides of the same decision

Leaving

What's pushing teams away

  • Very limited public documentation makes it difficult for new users or migrating teams to understand the data model without direct vendor engagement.
  • No publicly documented public REST API forces migrations to rely on the built-in export tooling, which may not cover all edge cases.
  • Pricing is fully custom with no transparent tier structure, making it hard to evaluate cost-effectiveness or negotiate during renewal.

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 Lemon Tech objects map to Mailchimp

Each row shows how a Lemon Tech 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.

Lemon Tech

Contact

maps to

Mailchimp

Audience Member

1:1
Fully supported

Lemon Tech contact records export as structured rows with name, email, phone, address, and any linked entity references. We map each contact to a Mailchimp Audience member via email as the dedupe key. Standard contact fields map to Mailchimp merge fields (FNAME, LNAME, PHONE, ADDRESS). Any linked company or entity reference from Lemon Tech's relational model becomes a tag on the Mailchimp contact (e.g., tag: 'LinkedTo:Acme Corp') since Mailchimp has no entity lookup. Contact status or type in Lemon Tech (client, vendor, referral) maps to a segmented tag group for audience filtering.

Lemon Tech

Entity (Company)

maps to

Mailchimp

Tag Group + Merge Field

lossy
Fully supported

Lemon Tech entities representing companies or organizations do not have a direct Mailchimp equivalent because Mailchimp has no Account or Company object. We decompose each Entity record into two parts: the entity name becomes a Mailchimp merge field (COMPANY) on the Contact record, and the entity-to-contact relationship becomes a tag (e.g., 'Entity:AcmeCorp'). For contacts with multiple linked entities, we create one tag per entity. If a contact has no email (entity-only record), we skip the contact import because Mailchimp requires an email address.

Lemon Tech

Matter

maps to

Mailchimp

Tag Group (no direct equivalent)

1:1
Fully supported

Lemon Tech Matters are case/project containers with no Mailchimp equivalent. We do not migrate Matters as records. For contacts that are Matter stakeholders, we extract the Matter name and create a tag (e.g., 'Matter:Smith-v-Jones') on the associated contacts to preserve the relationship at the contact level. The Matter status, dates, and billing data cannot be represented in Mailchimp and are flagged in the migration inventory as requiring a parallel CRM or project management tool if the customer needs to retain that data.

Lemon Tech

User

maps to

Mailchimp

Mailchimp Account User (out of scope)

1:1
Fully supported

Lemon Tech Users map to the Mailchimp account users who will administer the platform post-migration, not to contact records. We do not migrate User records as contacts. During scoping, we identify which Lemon Tech users will be Mailchimp account administrators and the customer provisions those accounts directly in Mailchimp. The mapping is informational: we provide a list of Lemon Tech user emails and recommended Mailchimp permission roles (Admin, Manager, Author) based on their source role context.

Lemon Tech

Custom Entity

maps to

Mailchimp

Merge Fields + Tags

lossy
Fully supported

Lemon Tech custom entities require decomposition because Mailchimp supports a maximum of 40 merge fields per Audience. We inventory all active custom entity types during discovery, identify the fields on each, and map them as follows: scalar values (text, number, date) become Mailchimp merge fields; multi-value or relational fields become tags. If a custom entity has more than 40 distinct fields across all types, we work with the customer to prioritize the 40 highest-value fields and document the remainder in the migration inventory for a potential custom integration or CRM replacement.

Lemon Tech

Attachment

maps to

Mailchimp

Not migrated (no equivalent)

1:1
Fully supported

Lemon Tech file attachments associated with entities or matters have no Mailchimp equivalent. Mailchimp supports image embedding in campaigns and document links in email body, but not contact-level file attachments. We extract attachment filenames and parent record associations and list them in the migration inventory. If the customer needs to preserve attachment access, we recommend a document management system (SharePoint, Google Drive, Dropbox) with links stored as Mailchimp merge fields or tag metadata.

Lemon Tech

Billing Record

maps to

Mailchimp

Not migrated (no equivalent)

1:1
Fully supported

Lemon Tech time entries and billing records linked to Matters have no Mailchimp equivalent. Mailchimp has no invoicing, time tracking, or financial record object. We extract the billing record metadata (matter reference, billable amount, date, contact link) and list it in the migration inventory. If the customer needs to retain billing history, we recommend exporting to a spreadsheet or accounting system as a parallel workstream outside the Mailchimp migration scope.

Lemon Tech

SQL Wrapper Data

maps to

Mailchimp

Not migrated (no equivalent)

1:1
Mapping required

Lemon Tech SQL Wrappers produce relational reporting tables that combine CRM data with custom SQL or third-party sources. These tables have no Mailchimp equivalent because Mailchimp's contact model is flat. We inventory all SQL Wrapper definitions during discovery, flag which wrappers reference live third-party data sources (these cannot be migrated as static records), and deliver a written map of wrapper outputs that the customer's admin can evaluate for re-implementation in a BI tool or a destination CRM if the migration extends beyond Mailchimp.

Pair-specific challenges

  • No published API means export-chunk dependency on Lemon Tech's server-side export task

    Lemon Tech has no publicly documented REST API for bulk data extraction. We rely on the built-in Entity export function, which runs as a server-side task and may have timeout limits for large datasets or complex SQL Wrappers. We handle this by chunking exports at the entity level (Contacts first, then Entities, then custom entities) and staging them incrementally. For datasets exceeding 20,000 records or complex multi-table SQL Wrappers, we coordinate with the customer to schedule exports during off-peak hours to avoid task queue backlogs. If the export times out, we restart from the checkpoint and do not re-export already-staged data.

  • Mailchimp merge field limit constrains custom entity migration

    Mailchimp imposes a maximum of 40 merge fields per Audience. Lemon Tech custom entities can have dozens of fields across dozens of entity types. A firm with 15 custom entity types averaging 5 fields each exceeds Mailchimp's limit immediately. We inventory all custom entity fields during discovery, select the 40 highest-value fields in consultation with the customer, and store the remainder as tags (with truncated values if necessary) or flag them in the migration inventory for a custom API integration or CRM replacement if the customer needs full relational preservation.

  • Matters, billing, and SQL Wrapper data have no Mailchimp home

    Lemon Tech Matters, time entries, billing records, and SQL Wrapper outputs have no equivalent object in Mailchimp. Mailchimp is an email marketing platform, not a CRM or billing system. We do not force-fit legal case data into contacts. Instead, we extract the contact-relevant associations (Matter name as a tag, billable status as a tag) and document the full Matter and billing record set in the migration inventory for the customer to evaluate for a parallel CRM, practice management, or accounting system. Customers who need to retain Matter history should not choose Mailchimp as their sole post-migration platform.

  • Mailchimp domain authentication required before sending

    Mailchimp requires SPF, DKIM, and DMARC domain authentication before new audiences can send at full deliverability. Domain authentication is also a prerequisite for the best inbox placement. We validate that the customer has access to their DNS settings during scoping. If authentication is not set up before migration, contacts migrate but sending is throttled or deferred until authentication completes. Mailchimp provides a step-by-step wizard; we guide the customer through the DNS record creation and verify propagation before the first campaign send. Skipping this step is the most common cause of deliverability issues in Mailchimp migrations.

  • Automation and customer journeys do not migrate across platforms

    Mailchimp Customer Journeys (automated email sequences triggered by subscriber behavior) are platform-native and do not migrate from or to Mailchimp. Lemon Tech has no native email campaign or automation capability, so there is no source automation to migrate. However, if the customer has previously used another email platform alongside Lemon Tech and has active automations there, those are separate from this migration scope. We deliver a written audit of any third-party email tool the customer requests to be reviewed, but we do not migrate automations from any email platform to Mailchimp as part of this engagement.

Migration approach

Six steps for a successful Lemon Tech to Mailchimp data migration

  1. Discovery and export inventory

    We audit the Lemon Tech instance to identify all active entity types, custom entity definitions, SQL Wrapper outputs, and Matter structures. We document which entity types have email addresses (required for Mailchimp) and which are entity-only. We assess the total record count per entity type and identify any custom entity fields that will exceed Mailchimp's 40-merge-field limit. The discovery output is a written export plan specifying chunk order, estimated export task count, and a preliminary merge field selection ranked by business value.

  2. Mailchimp audience planning and domain authentication

    We work with the customer to determine whether one or multiple Mailchimp Audiences are needed. A single Audience is simpler and suits most legal/professional services firms; multiple Audiences (e.g., one per entity type) add segmentation overhead but preserve cleaner contact records if entity types have conflicting field names. We initiate domain authentication (SPF, DKIM, DMARC) in parallel with export preparation because authentication propagation takes 24-72 hours and does not block export work. We also assess the customer's current contact list health (bounce rates, unsubscribe history) using any available Lemon Tech data to plan pre-import list cleaning.

  3. Export extraction and transformation

    We run Lemon Tech entity exports in chunked batches using the built-in export function, starting with Contacts (most critical, smallest dependency), then Entities (for company name and entity tags), then custom entities (for merge field mapping). Each export is transformed: entity names are normalized, entity-to-contact relationships are extracted as tags, custom entity fields are mapped to the agreed merge field set, and any SQL Wrapper outputs are inventoried separately as non-migratable artifacts. We validate row counts against the discovery inventory and flag any export that returns fewer records than expected.

  4. Mailchimp import and merge field provisioning

    We provision the merge fields in Mailchimp before any contact import using the Mailchimp API or audience settings UI. Merge fields are created with the correct types (text, number, date, address, phone) to match the source data. We then import contacts via the Mailchimp API (for large lists over 5,000) or CSV upload (for smaller lists) in batches of 5,000 records per import call to respect Mailchimp's API rate limits. Each batch emits an import report showing success, failure, and duplicate counts. Failed records are held in a reconciliation queue for manual review or re-export.

  5. Tag application and segment verification

    After contact import, we apply entity and Matter tags in batch via the Mailchimp Tags API. Tags are applied per contact based on the entity and Matter associations extracted from Lemon Tech. We verify segment previews in Mailchimp to confirm that tag-based segments resolve correctly (e.g., a segment for 'Tag:Entity:AcmeCorp' returns the expected contact count). If segments return unexpected counts, we troubleshoot the tag format or contact associations before finalizing.

  6. Cutover, validation, and migration inventory delivery

    We freeze Lemon Tech exports during the cutover window and run a final delta import of any contacts modified during migration. We validate total contact counts in Mailchimp against the source Lemon Tech export totals and spot-check 25-50 records for field-level accuracy. We deliver the full migration inventory: Matter list, billing record reference, SQL Wrapper output map, and attachment filename index. We do not rebuild Mailchimp Customer Journeys, automations, or signup forms as part of this scope; we deliver a written recommendation document for the customer's admin to rebuild these post-migration.

Most migrations land between one and three weeks for under 5,000 contacts with clean field mapping and no complex SQL Wrappers. Migrations with large datasets (over 15,000 contacts), multiple custom entity types, or complex SQL Wrapper definitions requiring manual field decomposition move to three to five weeks. Domain authentication setup (24-72 hours for DNS propagation) runs in parallel and does not extend the timeline if initiated during discovery.
