Overview
Moving from Simpleview CRM to Mailchimp is a directional migration: Simpleview is a vertical CRM built exclusively for Destination Marketing Organizations with Member Accounts, Listings, Coupons, Events, and Opportunities tied to a destination organization's taxonomy, while Mailchimp is an email marketing and marketing automation platform whose data model centers on Contacts, Audiences, Tags, Segments, and Campaigns. We extract contacts from Simpleview Member Accounts (with their contact records, address, and custom field data), resolve multi-select amenity vocabularies to Mailchimp tags, and map member tier classifications to Mailchimp segments. We do not migrate Simpleview Opportunities, Events, Coupons, or DMO-specific pipeline stages as these have no structural equivalent in Mailchimp; we deliver a written record of these objects for your admin to evaluate for manual re-entry or third-party tools. Simpleview's SOAP and XML-NVP API requires client-specific credentials obtained through the customer's project manager before data extraction can begin.
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 Simpleview 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.
Simpleview CRM
Member Account
Mailchimp
Contact
1:1Simpleview Member Account records (analogous to Companies in horizontal CRMs) contain primary contact data, address, and organization-level custom fields. We extract the primary Contact record linked to each Member Account, map the account name to the Company field on the Mailchimp contact, and preserve the source Simpleview AcctID as an external_id for deduplication. Any Member Account records without an associated contact are held in a reconciliation queue for manual review.
Simpleview CRM
Contact
Mailchimp
Contact
1:1Simpleview Contact records linked to Member Accounts migrate to Mailchimp Contacts within the target Audience. We map first name, last name, email address, phone, and postal address to the corresponding Mailchimp merge fields. The original Simpleview contact ID is stored in a custom external_id field for future sync reference.
Simpleview CRM
Custom_Account
Mailchimp
Merge Tag or Audience Group
lossyFields under Simpleview's Custom_Account category have no standardized schema across clients. We extract the full client-specific field definition during audit, map each custom field to either a Mailchimp merge tag (for single-value fields) or an Audience Group with group options (for picklist-type fields). Text-area and multi-line custom fields are stored as merge tags with full text content preserved. Required-field constraints are set on merge tags as specified by the customer during scoping.
Simpleview CRM
Amenity_MS (multi-select on Listings)
Mailchimp
Tags
lossyAmenity_MS values on Simpleview Listings use a client-defined vocabulary. We extract the full source amenity vocabulary, deduplicate it, and map each value to a Mailchimp Tag on the associated contact record. Unmapped amenities are flagged for manual review before final import. Any Listing-level amenities that cannot be attributed to a specific contact are summarized in a written document for the customer admin.
Simpleview CRM
Listing
Mailchimp
Tag + Company (deferred)
1:1Simpleview Listings represent partner/member directory entries tied to Member Accounts via AcctID. We do not create directory-style records in Mailchimp since Mailchimp has no listing or directory object. Instead, we extract the ListingID and link it to the corresponding Member Account contact record via a merge tag (listing_id). The customer admin can use this reference to build a supplementary directory in a separate tool if needed.
Simpleview CRM
Opportunity
Mailchimp
N/A (flagged for manual re-entry)
lossySimpleview Opportunity pipeline stages (meetings, sports, travel trade, group business) have no structural equivalent in Mailchimp. We extract a written inventory of all open and historical opportunities with their stage, value, close date, and associated Member Account. The customer admin re-enters pipeline data manually or evaluates a dedicated CRM if ongoing pipeline tracking is required.
Simpleview CRM
Event
Mailchimp
N/A (flagged for manual re-entry)
lossySimpleview Events are first-class objects with registrations linked to Member Accounts. Mailchimp has no event management or registration object. We extract a written inventory of all events with attendee lists, registration status, and event metadata. The customer admin evaluates event platforms (Eventbrite, Cvent, or others) for ongoing event management needs.
Simpleview CRM
Coupon
Mailchimp
N/A (flagged for manual re-entry)
lossySimpleview Coupons link to Listings and Member Accounts with date ranges (RedeemStart, RedeemEnd, PostStart, PostEnd) and offer text that may include HTML. Mailchimp has no coupon or offer management object. We extract coupon metadata as a written inventory for the customer admin to recreate in a coupon management tool or discount tracking spreadsheet.

Migration approach
Credential acquisition and API validation
We coordinate with the customer's Simpleview project manager to obtain production API credentials, confirm whether SOAP or XML-NVP transport applies, and validate the base URL and endpoint availability. We test connectivity with a lightweight read call on the Member Account endpoint before scoping proceeds. If credentials are delayed, we scope the rest of the project and hold the API validation phase open until credentials arrive.
Schema audit and field mapping design
We extract the full Simpleview Member Account and Contact schema including all Custom_Account and Custom_Account_MS field definitions, amenity vocabulary (Amenity_MS), and relationship metadata (AcctID to Contact linkage). We map each source field to either a Mailchimp standard merge field, a custom merge tag, or an audience group. Amenity vocabulary is extracted, deduplicated, and prepared for tag mapping. We deliver a written field map and a list of any source objects with no Mailchimp equivalent for customer review before any data moves.
Audience and tag structure setup in Mailchimp
We create the target Mailchimp Audience and configure merge tags to match the field map from step two. We pre-create any audience groups needed for multi-select fields. Tags are created for amenity vocabulary mapping. We validate merge tag constraints (required vs optional, character limits) against the source data sample to catch any format mismatches before the full import.
Data extraction, cleansing, and deduplication
We extract Member Account records with primary contact data and all custom field values via the Simpleview API. We run deduplication against email address as the primary key, flagging duplicates in Simpleview for customer resolution before import. We validate email addresses for deliverability and flag hard bounces for exclusion. We extract amenity vocabulary and prepare the tag mapping file alongside the contact records.
Staged import and tag application
We import contacts into Mailchimp via the Mailchimp API in batches of 5,000 records with rate-limit handling and exponential backoff. After contact import, we apply tags in a second pass using the amenity mapping file resolved in step four. We apply any segment criteria derived from Simpleview tier or status fields. Each batch emits a reconciliation count (imported vs rejected vs skipped) for customer review.
Cutover, validation, and written inventory delivery
We freeze Simpleview contact writes during cutover and run a final delta migration of any records modified during the migration window. We validate the Mailchimp audience record count against the Simpleview source count, spot-check 25-50 records for field-level accuracy, and obtain customer sign-off. We deliver the written inventory of objects not migrated (Opportunities, Events, Coupons, Listings, DMO-specific pipeline stages) with source record counts and field details so the customer admin can plan manual re-entry. We do not rebuild Simpleview workflows or automations in Mailchimp as standard scope.
