Migrate from Legal Workspace to Mailchimp

Every Legal Workspace Contact record becomes a Mailchimp Member within the target Audience. Email address is the unique identifier — used for matching, deduplication, and Mailchimp's subscription status tracking. The Member's merge fields carry all other contact properties from Legal Workspace.

Matter associations have no direct Mailchimp equivalent. We capture the Matter ID and Matter Name as a tag (e.g., TAG: Matter-2024-0412) and as a Merge Field so contacts can be filtered by matter in Mailchimp's segmentation builder. Multi-matter contacts receive multiple tags, one per matter.

The attorney or paralegal assigned to a Matter migrates as a tag identifying the responsible party (e.g., TAG: Attorney-Jones). Mailchimp has no owner field for Members — tags are the only mechanism for marking responsibility. Your team can filter campaigns or automations by assigned attorney using these tags.

Legal Workspace custom fields of type text, number, phone, and date map directly to Mailchimp Merge Fields with matching types. Mailchimp enforces a 255-character limit on text merge fields — longer fields are split across two merge fields or summarized. We flag truncation before migration so you can decide how to handle it.

Long-text case notes from Legal Workspace exceed Mailchimp's 255-character merge field limit. We split them into two or more Merge Fields (e.g., CASE_NOTE_1, CASE_NOTE_2) and append a truncation notice. If the full note must be preserved, we attach it as a PDF or document link via a URL merge field.

If Legal Workspace stores email open and click data from client communications, that history migrates as Mailchimp activity events on the Member record. This preserves engagement history in Mailchimp reports and enables segmentation based on prior client email interactions without starting from zero.

Legal Workspace opt-out flags map to Mailchimp's member status system: active → subscribed, unsubscribe requests → unsubscribed, hard-bounce records → cleaned. This is critical for deliverability — importing previously unsubscribed contacts as active members violates CAN-SPAM and GDPR obligations and damages sender reputation.

A Legal Workspace contact linked to multiple Matters appears once in Mailchimp as a single Member — deduplication is by email address. Each matter association becomes a separate tag on that Member. This is a key structural change from Legal Workspace's N:M contact-to-matter model to Mailchimp's 1:1 member model with tags for context.

Mailchimp does not store document attachments natively. Document references from Legal Workspace (e.g., matter agreements, court filings) migrate as a URL merge field pointing to a document repository your team designates — Google Drive, SharePoint, or your document management system. We do not re-upload files to Mailchimp.

Billing and invoice records from Legal Workspace have no Mailchimp equivalent and do not migrate. If billing data is needed for segmentation (e.g., 'client tier: Gold'), extract those values as a custom field in Legal Workspace before migration and we will map them to a Merge Field in Mailchimp.

Legal Workspace users (attorneys, paralegals) who are also contacts in the client database migrate as Members with a USER_TAG tag to distinguish internal users from external client contacts. Users who are only internal staff and not in the client contact list do not become Mailchimp Members unless they are on the email audience.

Matter-based automations — reminders, approval chains, intake workflows — have no Mailchimp counterpart. We export your Legal Workspace workflow definitions as a structured JSON document so your Mailchimp admin can reference them when rebuilding automations in the Customer Journey builder. This export is delivered with the migration plan.
