Overview
ASPEC CRM and Mailchimp serve fundamentally different purposes, so this migration is a contact-and-audience consolidation rather than a full CRM replacement. ASPEC holds Contacts, Companies, Opportunities, and Activity history; Mailchimp manages Audiences (subscribers), Tags, Segments, and Campaigns. We migrate the contact records with their associated company data encoded as merge fields, preserve ASPEC tags as Mailchimp tags, and flag Opportunities and Activities as objects that have no Mailchimp equivalent. Custom fields from ASPEC map to Mailchimp merge fields using a mandatory schema discovery step because ASPEC stores custom field definitions separately from record data. We do not migrate ASPEC automations, reports, or workflows to Mailchimp; we deliver a written inventory of every active automation for your team to rebuild in Mailchimp's automation builder.
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 ASPEC 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.
ASPEC
Contact
Mailchimp
Audience Member
1:1ASPEC Contact records map directly to Mailchimp Audience Members. We map first name, last name, email address, phone number, and physical address to the corresponding Mailchimp merge fields (FNAME, LNAME, EMAIL, PHONE, ADDRESS). Email address serves as the dedupe key during import. Any Contact without a valid email address is held in a reconciliation queue for the customer to correct before import; Mailchimp requires a valid email for every Audience Member.
ASPEC
Company
Mailchimp
Merge Fields (COMPANY, COMPANY_SIZE)
lossyASPEC Company records do not have a direct Mailchimp equivalent because Mailchimp has no Company or Account object. We encode company data into Mailchimp merge fields: the company name maps to a custom COMPANY merge field, and any company size or industry data maps to custom merge fields on the Audience. This means the 1:1 association between Contact and Company in ASPEC is preserved only as metadata on the individual Audience Member, not as a separate related record.
ASPEC
Tag
Mailchimp
Tag
1:1ASPEC tags on Contacts and Companies map directly to Mailchimp Tags on the corresponding Audience Members. We preserve the tag taxonomy during import, writing tags as comma-separated values in the Mailchimp Tags field. Tags used for segmentation in ASPEC (for example, industry verticals or account tiers) become Mailchimp Tags that can be used in Audience segmentation rules for campaign targeting.
ASPEC
Opportunity
Mailchimp
None
1:1ASPEC Opportunities (deal records with pipeline stages, values, and close dates) have no Mailchimp equivalent. Mailchimp does not have a deal, opportunity, or pipeline object. We do not migrate Opportunity records. If the customer requires pipeline tracking, they must implement it in a separate CRM or spreadsheet outside of Mailchimp. We flag every Opportunity during scoping so the customer can export it manually if needed for reporting.
ASPEC
Activity (calls, emails, meetings, tasks)
Mailchimp
None
1:1ASPEC Activity records (calls, emails, meetings, tasks) linked to Contacts do not migrate to Mailchimp. Mailchimp tracks engagement at the campaign level (opens, clicks, unsubscribes) but has no native activity timeline for individual contacts. The historical activity data from ASPEC cannot be reconstructed in Mailchimp. We flag this gap during scoping and recommend the customer export activity history as a CSV for their own records if required for compliance or audit.
ASPEC
Custom Field
Mailchimp
Merge Field
lossyASPEC custom fields (stored in a separate metadata layer from record data) map to Mailchimp Merge Fields on the Audience. We run a mandatory schema discovery step to enumerate all active ASPEC custom fields and their data types before migration. Text fields map to Mailchimp text merge fields; date fields map to date merge fields; number fields map to number merge fields; checkbox or multi-select fields map to Mailchimp text merge fields with comma-separated values. Merge field names in Mailchimp are uppercase and limited to 30 characters, so we truncate and sanitize ASPEC field names during mapping.
ASPEC
User/Owner
Mailchimp
Admin Role
lossyASPEC Users and Owners assigned to Contacts and Companies map to Mailchimp Admin roles. However, Mailchimp Admin roles do not attach to individual contact records the way ASPEC ownership does. We document which ASPEC users correspond to which Mailchimp admin accounts during scoping so that the customer can assign appropriate Mailchimp permission sets post-migration. Individual record-level ownership does not migrate.
ASPEC
Pipeline Stage
Mailchimp
None
1:1ASPEC Pipeline Stages define deal progress and are configured per pipeline. Mailchimp has no pipeline or stage concept. Pipeline stage definitions are flagged as non-migratable during scoping. If the customer has used pipeline stages to categorize customers or prospects (for example, for customer lifecycle stages), we recommend rebuilding this segmentation logic using Mailchimp Tags and Segments post-migration.

Migration approach
Scoping and export coordination
We run a scoping call with the customer to understand the ASPEC data volume (total contacts, total companies, total tags, total custom fields), confirm the export method available from ASPEC (UI export or database export), and identify any suppressed or invalid email addresses that require customer action before import. We also identify which ASPEC automations, workflows, or reports the customer wants documented for rebuild. The output is a written migration scope and a data readiness checklist for the customer.
Schema discovery for custom fields
We enumerate all active ASPEC custom fields and their data types by accessing the customer's ASPEC export or schema metadata. We map each custom field to a Mailchimp Merge Field type: text fields to Mailchimp TEXT, date fields to DATE, number fields to NUMBER, and multi-select fields to TEXT with comma-separated values. We sanitize field names to comply with Mailchimp's 30-character uppercase limit. The customer approves the merge field mapping before we create any Mailchimp Merge Fields on the target Audience.
Mailchimp Audience preparation
We create the Mailchimp Audience (or identify the existing target Audience) and configure the Merge Fields based on the approved schema mapping. We set up Tags in Mailchimp that correspond to the ASPEC tag taxonomy. If the customer has existing Mailchimp suppressions (unsubscribed or bounced contacts), we coordinate importing these as a suppression list first so that migrated contacts matching suppressed emails are handled correctly per Mailchimp policy.
Contact and company data import
We import ASPEC Contacts as Mailchimp Audience Members using the Mailchimp Marketing API with batch processing and rate-limit handling (1,000 requests per 10-second window). Email address is the dedupe key. ASPEC Company data is encoded into Merge Fields on each contact record. We import tags alongside contact records. Records with invalid or missing email addresses are held in a separate error file for customer resolution. Each import batch emits a reconciliation count for customer sign-off.
Tag and segmentation validation
We validate that all ASPEC tags have been written to Mailchimp as Tags on the corresponding Audience Members. We spot-check tag assignments against the ASPEC source data to confirm mapping accuracy. If the customer used ASPEC segments for targeting, we document the segment logic (filter criteria, tag usage, field conditions) as a written spec for rebuilding in Mailchimp Segments or Customer Journeys.
Automation and workflow handoff
We deliver a written inventory of every active ASPEC automation and workflow with its trigger, conditions, and actions described in plain language. We do not migrate automations to Mailchimp because ASPEC automations and Mailchimp Customer Journeys are different trigger models. The customer's team uses the inventory document to rebuild automations in Mailchimp. We do not provide post-migration admin support for Mailchimp automation rebuild as standard scope; this is a separate engagement if required.
