Overview
Moving from monday CRM to Mailchimp is a downselection migration from a visual pipeline CRM to an audience-centric email marketing platform. monday CRM stores contacts as People with deal associations, pipeline stages, and custom column data; Mailchimp stores contacts as audience Members with merge fields, tags, and segment filters. We migrate People records into Mailchimp audiences 1:1, map monday CRM custom column properties to Mailchimp merge fields, and carry deal values and pipeline stage associations as tags on the subscriber record. monday CRM Pipelines, Boards, Items, and Subitems have no structural equivalent in Mailchimp and do not migrate; we deliver a written inventory of these objects so the customer's admin can decide how to recreate the information in Mailchimp segments or as notes on the contact record. Automations, file attachments, and the monday.com legacy Recipe infrastructure do not migrate.

Object mapping
Each row shows how a monday 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.
monday CRM
People (Contacts)
Mailchimp
Audience Member
1:1monday CRM People records map directly to Mailchimp Audience members. The monday person name becomes First Name and Last Name merge fields (or a combined Name field if the source uses a single-name format). Email address serves as the Mailchimp subscriber hash dedupe key. We preserve any CRM property values (phone, company, title, location) as additional merge fields. Subscriber status in Mailchimp defaults to subscribed for all migrated contacts unless the monday CRM record has an explicit unsubscribe or bounced status that we carry over.
monday CRM
Custom Column (text, number, date, phone)
Mailchimp
Merge Field
1:1monday CRM custom column values of text, number, date, phone, and currency types map to Mailchimp merge field equivalents. TEXT columns become text merge fields, numeric columns become number merge fields, date columns become date merge fields, and phone columns become phone merge fields. We pre-create the merge field schema in the destination Mailchimp audience before import. Column types with no Mailchimp equivalent (formulas, dependencies, links) are flagged in the mapping document for manual note addition or exclusion.
monday CRM
Deal (CRM Item with Pipeline)
Mailchimp
Tag on Member
1:manymonday CRM Deals attached to a Pipeline do not have a direct Mailchimp equivalent because Mailchimp does not have a deal value or weighted pipeline concept (unless the customer licenses Mailchimp CRM Premium). We map deal data as tags on the subscriber record: the pipeline name becomes a tag prefix (e.g., Sales Pipeline), the deal value is stored as a tag value or merge field (deal_value__c), and the stage name becomes a tag (e.g., Stage: Qualified). If the customer has Mailchimp CRM, we evaluate mapping Deals to Mailchimp Deals instead.
monday CRM
Pipeline Stage
Mailchimp
Tag (prefixed)
lossyEach monday CRM Pipeline Stage maps to a Mailchimp tag with a consistent naming prefix (e.g., Pipeline Stage: Discovery, Pipeline Stage: Proposal, Pipeline Stage: Closed Won). Tags allow the customer to segment audiences by deal stage for targeted re-engagement campaigns. We preserve the original stage probability percentage as a merge field (stage_probability__c) if the customer requests it for campaign personalization.
monday CRM
Board (CRM Board)
Mailchimp
Audience
1:manymonday CRM CRM boards do not map to a single Mailchimp object. We document each CRM board as a written inventory item recommending whether to create a separate Mailchimp audience (for boards representing distinct business units or client lists) or to use tags for board-level segmentation within a single audience. The customer decides the audience strategy during scoping.
monday CRM
Item (CRM Board Row)
Mailchimp
Member
1:1monday CRM Items on a non-CRM board (i.e., contacts stored as Items rather than People) are enumerated and merged into the contact migration. We flag Item-sourced contacts versus People-sourced contacts during scoping so that the customer understands whether the bulk export covers their full contact list or whether an additional API enumeration step is required. Item name becomes the contact Name; any person-type column on the item captures email and phone.
monday CRM
Subitem
Mailchimp
Tag or Note
1:1monday CRM Subitems are not included in the bulk account export or per-board Excel export. We enumerate subitems via the monday.com API using each parent Item's ID, which multiplies API call volume. Subitems (commonly used for line items, related activities, or task breakdowns) do not have a native Mailchimp equivalent. We map subitem names as tags on the parent contact (e.g., Related Activity: Proposal Call) or document them in a written inventory for manual follow-up if the information is not mission-critical.
monday CRM
User / Owner
Mailchimp
Tag on Members owned
1:1monday CRM Users assigned as owners of People records or Deals are enumerated during scoping. We match by email and apply a tag to each owned contact (e.g., Owner: [email protected]) so that the customer can segment by account owner in Mailchimp for owner-specific campaigns. Mailchimp does not have a user or team member object; ownership is represented through tagging only.
monday CRM
Updates (Comments)
Mailchimp
Note
1:1monday CRM Updates on People records (comment threads, internal notes) can be exported per person via the monday.com API. Mailchimp does not have a native comment or note object on individual members. We migrate update text as Mailchimp notes on the member record, preserving the original timestamp. High-volume update threads (many comments per contact) are summarized rather than fully replicated to avoid API bloat.

Migration approach
Discovery and contact audit
We enumerate all monday CRM People records, CRM-typed Items with person columns, and custom column definitions across every board in scope. We identify which contacts exist as monday People versus Item-attached person columns (a common pattern when teams did not activate the CRM module's People feature). We capture pipeline definitions, stage names, deal value columns, and owner assignments for tag taxonomy planning. We also identify any automations, subitem counts, and file attachments that require separate handling. The output is a written migration scope with record counts, merge field schema, and tag taxonomy recommendations.
Destination audience and schema preparation
We create the target Mailchimp audience (or select an existing audience) and pre-create all required merge fields matching the monday CRM custom column types. We design the tag taxonomy for pipeline stages, deal associations, owner assignments, and board-level segmentation. If the customer has multiple monday CRM boards that logically map to separate Mailchimp audiences, we configure each audience with the appropriate merge field schema. Mailchimp API credentials and any required OAuth scopes are validated before data export begins.
monday.com data export via API with rate-limit handling
We export People records via the monday.com API with exponential backoff on 429 responses. On Basic and Standard plans (1,000 API calls per day), we schedule export jobs overnight to maximize the available daily window. Subitems are enumerated per parent Item ID separately, with the total subitem count flagged during scoping. We extract custom column values, pipeline stage assignments, deal values, owner emails, and update timestamps alongside each record. The export produces a normalized intermediate JSON file with all monday-specific IDs preserved for reconciliation.
Transform and merge field mapping
We transform the monday export into Mailchimp member format, mapping name fields to First Name and Last Name merge fields, email to the subscriber hash key, and CRM custom columns to the pre-created merge field schema. Deal data (pipeline name, stage, value) generates tags on each member. Owner email generates an Owner tag. We apply subscriber status (subscribed, unsubscribed, bounced) based on any monday CRM communication preferences stored in custom columns. The transform step resolves any monday CRM person column lookups where a contact record references another person within the same export.
Mailchimp audience import and validation
We import members into the destination Mailchimp audience via the Mailchimp Members API (for individual or small-batch inserts) or the Mailchimp Bulk Import API (for large lists over 1,000 records). Each import batch is reconciled against the source record count before the next batch begins. We validate that merge field values were written correctly by sampling 25-50 records per batch and comparing against the source. Tag assignments are verified post-import via the Mailchimp Tags API. Any records rejected by Mailchimp (invalid email format, compliance flags) are held in a reconciliation queue for the customer to review.
Cutover, automation inventory handoff, and post-migration validation
We freeze monday CRM writes during cutover and run a final delta migration of any contacts modified since the initial export. We deliver the automation inventory document and segment rebuild guide to the customer's admin team. We perform a final row-count reconciliation between the monday CRM People export and the Mailchimp audience member count, and spot-check merge field completeness. We do not rebuild monday.com automations as Mailchimp Customer Journeys; that work is a separate engagement for the customer's marketing admin or a Mailchimp partner.
