Migrate from Nimble CRM to Mailchimp

Nimble Contacts map to Mailchimp Subscribers. Email address is the dedupe key; we normalize formatting (lowercase, trim whitespace) and flag duplicates before import. First Name and Last Name migrate to FNAME and LNAME merge fields. Phone numbers migrate to PHONE if the destination Mailchimp plan supports it. The Nimble Contact's created date maps to Mailchimp's Member Since timestamp for historical reference.

Nimble Tags map to Mailchimp Labels. Tags are flat string labels in Nimble; Labels are string labels in Mailchimp. We extract all unique tags per Contact and write them as Label entries in Mailchimp. If a Contact has more than 50 labels, we surface this as a warning because Mailchimp display can become cluttered; the customer decides whether to merge overlapping tags during scoping.

Nimble custom fields on Contacts map to Mailchimp Merge Fields. We handle type mapping: text fields to TEXT merge fields, date fields to DATE merge fields, picklist fields to RADIO or DROPDOWN merge fields depending on whether the destination plan supports multi-select. Mailchimp caps merge fields at 30 per Audience; if the source has more than 30 unique field names, we prioritize the 30 most operationally critical and document the remainder as a post-migration import option.

Nimble Company records have no Mailchimp equivalent. Mailchimp is contact-centric and does not have an Account or Organization object. We extract Company name and domain from each Contact record and store Company name in a COMPANY merge field if the customer requests it, but the Company→Contact relationship (multiple Contacts per Company) is lost. The customer documents this structural gap during scoping.

Nimble Deals do not migrate. Mailchimp has no opportunity or pipeline object. Deal values, stages, owners, and close dates have nowhere to land in Mailchimp. We export Deals as a CSV inventory during discovery and deliver it as a written record so the customer can reference closed-won values when rebuilding customer journeys. For active pipeline data, the customer must choose a different destination CRM if deal tracking is required.

Nimble Activity records (logged calls, meetings, tasks, email history) have no Mailchimp equivalent. Mailchimp tracks campaign-level opens and clicks per subscriber but does not store a sales activity timeline. We export a summary CSV of activity counts per Contact (total calls, total meetings, last contact date) and write it to a custom merge field or as a note attachment in Mailchimp for reference, but the granular activity record does not migrate.

Nimble Workflow automations have no export path and do not migrate to Mailchimp Customer Journey Builder because the trigger-action models are structurally different. We conduct a Workflow audit during scoping, document each workflow's trigger, conditions, and actions, and deliver a written rebuild guide for Mailchimp Customer Journey Builder with specific trigger equivalents (e.g., Nimble tag-added triggers map to Mailchimp 'Tag Added' Journey entry triggers). The admin rebuilds automations post-migration.

Nimble Segments are saved dynamic filters; Mailchimp Audiences are static subscriber lists. We export the constituent contacts from each Nimble Segment rather than the segment definition, since dynamic filter logic does not transfer. Each segment's contact list becomes a Mailchimp Audience. Customers using Nimble Segments for audience management can reconstruct equivalent static audiences in Mailchimp by importing the exported contact list per segment.
