Overview
Friday CRM is a sales CRM built around Companies, Contacts, and Deals with a kanban pipeline. Mailchimp is an email marketing platform that stores contacts as Audience Members and optionally links them to Company records. The two platforms share a native Mailchimp integration but have fundamentally different data models. We migrate Contacts to Members, Company records to Mailchimp Companies (linked via CRM merge fields), and Tags directly. Deals and pipeline stages have no structural equivalent in Mailchimp and are flagged with a reference export before cutover. Activity history, attachments, and custom field types require manual reconciliation because Friday's undocumented API and Mailchimp's merge field type constraints may not preserve the original data faithfully. We deliver a written inventory of every Friday automation for your admin to rebuild in Mailchimp Customer Journeys.
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 Friday CRM 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.
Friday CRM
Contact
Mailchimp
Member
1:1Friday CRM Contact records map to Mailchimp Audience Members. The email address serves as the primary key and dedupe field. Standard contact fields (first name, last name, phone, address) map to Mailchimp merge fields FNAME, LNAME, PHONE, and the address merge field. We extract and normalize email addresses, flag hard bounces and unsubscribes as suppression records, and split contacts into subscribed and non-subscribed segments for separate Mailchimp import to preserve status. Contacts without email addresses cannot migrate as Members and are flagged in the reconciliation report.
Friday CRM
Company
Mailchimp
Company
1:1Friday CRM Company records map to Mailchimp Company records. We extract company name, website, industry, and address fields. In Mailchimp, Company records are linked to Members via CRM merge fields (MAILINGCOMPANY maps to Company Name, WEBSITE maps to Company Website). We resolve the Company-to-Member link using the email domain as a heuristic match when a Contact has a linked Company. If the destination Mailchimp account does not have Companies enabled, we map company name to a text merge field instead and flag the configuration difference.
Friday CRM
Deal
Mailchimp
None (flagged reference export)
lossyFriday CRM Deals have no structural equivalent in Mailchimp. Mailchimp does not have an Opportunity or pipeline object, and its automation model (Customer Journeys) is email-triggered rather than deal-stage-triggered. We cannot migrate Deals as live CRM records. We generate a reference export of all open Deals including name, value, stage, associated Contact email, and close date as a CSV handoff document. The customer's admin uses this to re-enter deal data manually or to document pipeline context in a spreadsheet post-migration. Closed-won Deals may be entered as Campaign Member notes or tagged Member records if the customer wants a proxy record in Mailchimp.
Friday CRM
Pipeline Stage
Mailchimp
Segment
lossyFriday CRM pipeline stages (kanban columns) have no structural equivalent in Mailchimp. We create Mailchimp Segments that correspond to the original pipeline stage labels. Contacts and Deals linked to a given stage are tagged or segmented in Mailchimp using a segment rule matching the Deal stage field. This preserves the marketing-side pipeline context for segmented campaigns (for example, a campaign targeting contacts in the 'Demo Scheduled' stage), but it does not replicate a live CRM pipeline.
Friday CRM
Tag/Label
Mailchimp
Tag
1:1Friday CRM tags on Contacts and Deals migrate directly to Mailchimp Tags. We parse comma-separated tag values from the Friday export, deduplicate across all records, and import tags as Mailchimp Tags associated with each Member by email match. The free Mailchimp plan supports up to 20 tags per Audience; accounts on Essentials and above support up to 60 tags. We check the tag count against the customer's Mailchimp plan tier and flag any overflow requiring plan upgrade or tag consolidation before migration.
Friday CRM
Activity/Note
Mailchimp
Note
1:1Friday CRM notes and activity history (linked to Contacts and Companies) migrate as Mailchimp Notes on Member profiles. We extract note text, author, and timestamp from the Friday export, resolve the associated Contact by email, and create Mailchimp Notes. Mailchimp Notes are stored as flat text on a Member profile without a chronological timeline view, which means the activity history loses its deal and company context in the Mailchimp interface. We flag this limitation and recommend the customer export a full notes history from Friday CRM before cutover as a reference archive.
Friday CRM
Custom Field
Mailchimp
Merge Field
lossyFriday CRM custom fields on Contacts and Companies map to Mailchimp Merge Fields. We audit Friday's nine field types and perform type mapping: text, multi-line text, URL, and radio select map to Mailchimp TEXT merge fields; single checkbox maps to Y/N text; number maps to NUMBER; date maps to DATE; multiple checkboxes require 1:N split into separate boolean text merge fields. Dropdown becomes a Mailchimp dropdown if the plan supports it, or TEXT on lower tiers. Mailchimp requires merge fields to be pre-created in the Audience Settings before import; we design the merge field schema and submit it for customer approval before running any data import.
Friday CRM
Attachment
Mailchimp
None (not supported)
lossyFriday CRM attachments are not included in the platform's documented CSV export or public API. We flag this gap during discovery and recommend the customer manually download any relevant file attachments from the Friday CRM interface before the migration cutover date. We do not migrate attachment metadata or file references as part of the standard scope because there is no reliable export path from Friday CRM.
Friday CRM
Integrations
Mailchimp
None (OAuth reconnection required)
lossyFriday CRM's native Mailchimp integration stores OAuth credentials and connection state within the platform that are not exported as part of the migration data. The bidirectional sync configuration, contact list mapping, and any custom field mapping rules set up in Friday's Mailchimp integration do not transfer to the destination Mailchimp account. After migration, the customer must re-establish the Mailchimp integration from within Mailchimp's connected apps or by creating new API credentials. We provide step-by-step reconnection guidance as part of the post-migration handoff document.

Friday CRM gotchas
No mobile app means no mobile access during migration cutover
CSV export may not capture full activity history
Custom field types may require reconfiguration in destination CRM
No documented API rate limits or bulk endpoints
Integrations must be re-established manually in destination CRM
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
Discovery and export audit
We audit the Friday CRM data export by generating the ZIP archive from Settings and cataloguing every object, field, and relationship present. We identify which objects are included in the export, which are missing (attachments, integration credentials, API-only records), and which cannot map to Mailchimp objects at all. We present the customer with a written data inventory that includes record counts per object, a sample of the field structure for Contacts and Companies, and a gap analysis listing what will and will not migrate. The customer approves the scope before any schema work begins.
Mailchimp audience and merge field schema design
We design the Mailchimp Audience structure and merge field schema to accommodate the Friday CRM field mapping. This includes creating the Audience (or selecting an existing one), defining all required merge fields with their types, designing segments that correspond to Friday pipeline stages, and establishing a tag naming convention. If the customer uses Mailchimp Companies, we configure the Company object and map the CRM merge fields that link Members to Companies. We submit the schema design to the customer for approval and deploy it to the destination Mailchimp account before any data is imported.
Data export, cleansing, and transformation
We extract the full CSV export from Friday CRM and run a data quality pass. This includes normalizing email addresses, flagging records with missing required fields (email address is required for Mailchimp Members), deduplicating contacts by email, normalizing tag names, and converting Friday field types to Mailchimp merge field values per the agreed mapping spec. We flag any Friday custom field values that cannot be represented in the target merge field type and present them to the customer as a resolution choice before transformation.
Import and deduplication
We import Contacts as Members using Mailchimp's batch import endpoint with upsert logic keyed on email address. Each import batch is followed by a deduplication reconciliation that merges duplicate Member profiles and resolves field conflicts (taking the most recent, the most complete, or the customer-specified field). Tags are applied post-import via the tag assignment endpoint. Company records are created and linked to Members via the CRM merge fields. We validate record counts against the source Friday CRM export and flag any discrepancy exceeding the agreed tolerance threshold for re-import.
Cutover and reference export delivery
We schedule the cutover during an off-peak window agreed upon with the customer. During cutover, Friday CRM writes are frozen (we advise the customer to communicate a data-freeze window to their team), and any records modified after the last data pull are reconciled as a final delta import. We deliver the Deals reference export CSV, the full notes archive, and the integration reconnection guide. We do not decommission the Friday CRM account as part of standard scope; the customer decides when to cancel based on their own retention policy.
Post-migration handoff
We deliver a written automation inventory documenting every Friday CRM workflow and the equivalent Mailchimp Customer Journey trigger, condition, and action for each. We do not rebuild automations as Mailchimp Customer Journeys within the migration scope. We provide a one-week hypercare window for reconciliation issues including duplicate Members discovered post-import, missing contacts, and merge field value corrections. Post-migration admin support, team training, and Customer Journey rebuild are separate engagements.
