Overview
Moving from Daylite to Mailchimp is a scoped contact-and-audience migration, not a full CRM replacement. Daylite stores contacts as People records with rich custom fields, address data, and group membership; Mailchimp receives them as Audience members with merge field properties and tags. We extract the Daylite People CSV from your database export, resolve email deduplication (multiple people sharing an email address are common in small businesses), map Daylite Groups to Mailchimp Tags or Segments, and push custom field values into Mailchimp merge field equivalents. Daylite Opportunities, Projects, Tasks, and Appointments have no Mailchimp equivalent and are excluded from migration scope. Daylite automation rules (if any are present via iOSXpert) and any Marketing&Chat plugin sync configurations do not migrate; we deliver a written inventory of these for your admin to rebuild as Mailchimp Customer Journey automations.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Daylite 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.
Daylite
People
Mailchimp
Audience Member
1:1Daylite People records map to Mailchimp Audience members. The email address is the required dedupe key for Mailchimp import. Daylite allows multiple People records with the same email (e.g., family members sharing an inbox), which Mailchimp collapses to a single member with combined properties; we surface a dedup report so the customer decides whether to merge or keep separate records before import. First name, last name, phone, and address fields map to Mailchimp merge fields FNAME, LNAME, PHONE, and the address merge fields respectively.
Daylite
Custom Fields on People
Mailchimp
Merge Fields
lossyDaylite custom fields on People (text, date, number, dropdown, checkbox types) map to Mailchimp merge tags created at the audience level before import. We extract the custom field definition table from the Daylite export, present the customer with a merge field creation worksheet, and pre-create merge tags in Mailchimp with the correct type (text, number, date, dropdown) before the member import runs. Dropdown fields from Daylite become dropdown merge tags in Mailchimp.
Daylite
Groups
Mailchimp
Tags or Segments
1:manyDaylite Groups containing People members map to Mailchimp Tags. Each Daylite Group becomes a tag of the same name applied to all members of that group. If the customer has Group hierarchies (parent and child groups), the parent group maps to a Mailchimp Tag and the child group maps to a tag with a parent-child naming convention (e.g., 'Region-West' and 'Region-East' under 'Region'). Segments with condition logic (e.g., 'People in Group A with custom field X = Y') are presented as Mailchimp pre-built Segments created during import.

Tags (Daylite)
Mailchimp
Tags (Mailchimp)
1:1Daylite's separate tag system (distinct from Groups) maps directly to Mailchimp Tags. Tags are additive labels that a single Person can hold multiple of. We extract the Daylite tag assignment table and apply each tag to the corresponding member during import. Tag names are normalized to remove characters Mailchimp does not support (angle brackets, non-UTF-8 characters).
Daylite
Notes on People
Mailchimp
Member Notes
1:1Daylite Notes attached to People migrate as Mailchimp member notes. Note creation date becomes the Mailchimp note timestamp. Note body migrates as plain text (HTML note content is stripped). Mailchimp limits notes to 1,000 characters; notes exceeding this are truncated with a '(truncated)' suffix and the customer is notified of the affected records.
Daylite
Attachments on People
Mailchimp
External Storage Reference
1:1Daylite exports attachments in a flat folder with filenames referencing parent object type and ID. We cross-reference the attachment folder with the People CSV and flag any attachments to People records. Mailchimp does not host file attachments natively on member profiles; we provide a written reference document mapping each attachment to its Daylite-sourced file path so the customer's admin can manually attach or link files in their chosen storage system.
Daylite
Companies
Mailchimp
Merge Fields (Organization Reference)
lossyDaylite Company records do not have a direct Mailchimp equivalent because Mailchimp has no native Account or Company object. We map Company name, industry, and website to Mailchimp merge fields (COMPANY, INDUSTRY, COMPANY_WEBSITE) on the member profile. The customer's admin configures these merge fields during scoping if they are not already present in the destination audience. Company-People linkage (a Person belongs to one Company in Daylite) is preserved by ensuring the Company merge field is set for every migrated Person.
Daylite
Opportunities
Mailchimp
Not Migrated
lossyDaylite Opportunities (deal pipeline records with stage, value, probability, and close date) have no Mailchimp equivalent. Mailchimp is an email marketing platform and does not track deal stages, pipeline values, or sales probability. We flag the Opportunity table in the export as excluded and deliver a written record count so the customer knows the volume of deal data being left behind. If the customer needs deal data in a new system, a separate CRM migration engagement is required.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Daylite gotchas
Database export download expires after 14 days
Billings Pro self-serve is discontinued, cloud migration required
Plugin-stored data is only exportable if the plugin is installed
Custom field definitions must be manually mapped
Pipeline stage names are plain text, not a managed taxonomy
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms
E-commerce data requires active store connection
Pair-specific challenges
Migration approach
Export trigger and scoping
We confirm the Daylite export download link is active (generated within 14 days). If the link has expired, we instruct the customer to trigger a new export from Account Settings > My Info > Create Data Export. We receive the exported CSV archive and audit the table list for People, Companies, Groups, Tags, Notes, and custom field definitions. We count unique People, unique email addresses, Group membership rows, and tag assignment rows to size the migration scope and timeline.
Merge field design and audience preparation
We extract the Daylite custom field metadata table and present the merge field creation worksheet to the customer. For each custom field on People, the customer chooses a Mailchimp merge tag name (up to 10 characters, uppercase, alphanumeric) and confirms the field type mapping. We pre-create all merge tags in the destination Mailchimp audience via the Mailchimp API before any member import begins. We also confirm the Company merge fields (COMPANY, INDUSTRY, COMPANY_WEBSITE) are configured if the customer wants organizational data preserved.
Deduplication review and transformation
We run the People CSV through a dedup analysis that flags every email address appearing in more than one record. The customer reviews the dedup report and provides instructions for each multi-email record (merge field values, keep both as separate contacts with modified emails, or archive). We transform the source CSV with the dedup decisions applied, normalize tag and group names to Mailchimp-supported characters, and convert any non-UTF-8 text to UTF-8 before import.
Audience member import via Mailchimp API
We import transformed People records into the destination Mailchimp audience using the Mailchimp Members API (PUT for upsert with email as the unique identifier). Each import batch is 500 members with exponential backoff on rate limit responses. After each batch, we validate the returned member status (subscribed, unsubscribed, pending) against the Daylite source contact status. Tags and Group memberships are applied in a second pass via the Tags API endpoint after all members are present in the audience.
Tag and segment reconstruction
We apply Daylite Group memberships as Mailchimp Tags. Each unique Group name becomes a tag and is applied to all members who were members of that Group in Daylite. If the customer requested Segments (pre-built filters with conditions rather than static tag lists), we create the Segment definitions in Mailchimp using the Segment criteria the customer specified during scoping. Tags applied in the previous step are available as Segment filter criteria.
Notes import and reconciliation report
We import Daylite Notes on People as Mailchimp member notes via the Notes API endpoint, setting the note timestamp to match the Daylite note creation date. Notes exceeding 1,000 characters are flagged in the reconciliation report. We deliver a final reconciliation report showing: total People records in Daylite, total members in Mailchimp after dedup, total tags applied, total notes migrated, total notes truncated, and the count of Company merge fields populated. The customer validates the counts and spot-checks records before cutover.
