Overview

What this migration involves

Migrating from Agillic to Mailchimp is a structural downgrade on custom object depth but an upgrade in usability and cost predictability. Agillic stores every contact as a fully customisable Recipient record with arbitrary client-defined properties and a full activity timeline tied to Flow Execution IDs; Mailchimp uses a flat subscriber model with up to 30 merge fields (80 on Premium). We enumerate every Agillic recipient property during discovery, merge or drop fields that exceed Mailchimp limits, and preserve the most operationally critical attributes in Tags or merge fields. Activity history migrates as Mailchimp activity stats (opens, clicks, bounces) which are preserved per-contact, but Flow execution timelines tied to Flow Execution IDs cannot be reconstructed in Mailchimp's reporting model. We do not migrate Agillic Flows, Templates, or Global Data Tables as portable code; we deliver a written inventory of each for the customer's admin to recreate in Mailchimp's automation builder.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Why teams make this switch

Two sides of the same decision

Leaving

Agillic

What's pushing teams away

  • Rate limits and API quotas are not publicly documented, creating uncertainty for teams planning large-scale data migrations or integrations.
  • The platform's heavy reliance on developer configuration for data synchronisation, custom flow elements, and content templates means marketing teams without technical support encounter bottlenecks.
  • Complex workflow logic built by developers becomes difficult for non-technical marketers to modify independently, limiting operational agility.
  • Exporting Activity data requires external analysis tools; Agillic itself lacks built-in advanced analytics dashboards for post-campaign insight generation.

Choosing

Mailchimp logo

Mailchimp

What's pulling them in

  • Generous free tier with up to 500 contacts allows small teams to validate email marketing before committing to a paid plan.
  • Intuitive drag-and-drop email builder and 130+ templates let non-technical users produce professional campaigns without HTML or CSS knowledge.
  • 300+ native integrations, especially Canva and Shopify, make it easy to connect existing tools without custom development work.
  • Detailed open-rate, click-through, and campaign analytics give small businesses actionable insights without a dedicated marketing team.
  • One-platform consolidation of email campaigns, automations, landing pages, and ads reduces tool sprawl for lean marketing teams.

Object mapping

How Agillic objects map to Mailchimp

Each row shows how a Agillic 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.

Agillic

Recipient

maps to

Mailchimp

Contact (Mailchimp Subscriber)

1:1
Fully supported

Agillic Recipients map to Mailchimp Contacts. We enumerate every custom recipient property during discovery via the Recipient API and map each to a Mailchimp merge field. If the property count exceeds 30 (standard) or 80 (Premium), we consolidate multi-value string properties into Tags, flag numeric or date fields for conversion to text merge fields, and document the dropped fields for the customer to assess. The recipient email address is the Mailchimp subscriber identifier and dedupe key.

Agillic

Activity Logs

maps to

Mailchimp

Contact Activity Stats

1:1
Fully supported

Agillic Activity records (sends, opens, clicks, bounces, SMS deliveries) migrate as Mailchimp activity history entries against each contact. Mailchimp preserves aggregate open and click stats per contact in its interface, but does not expose event-level timestamps for every individual open/click the way Agillic's Activity Export does. We migrate what Mailchimp can represent and document the full event-level history from Agillic Activity Export as a data export for the customer's analytics team.

Agillic

Flow Execution ID

maps to

Mailchimp

Tag

lossy
Fully supported

The Agillic Flow Execution ID cannot be natively represented in Mailchimp's activity model. We store the Flow Execution ID as a Mailchimp Tag on each affected contact record (e.g., tag format: flow_execution_[ID]) so the customer can reference which Agillic flow triggered a given communication, though Mailchimp's automation builder cannot act on these tags as triggers.

Agillic

Global Data Tables

maps to

Mailchimp

Custom Fields or Tags

many:1
Mapping required

Agillic Global Data Tables are custom relational structures referenced within Flows. Mailchimp has no relational table concept. We export table schemas and row data, then map tabular fields to Mailchimp merge fields where the field maps to a contact attribute, or to Tags where the data represents segment classification. Many Global Data Table use cases (product catalogs, subscription tiers, loyalty points) cannot be represented in Mailchimp and require a separate external system or a Mailchimp-integrated app.

Agillic

Templates

maps to

Mailchimp

Templates

1:1
Mapping required

Agillic email, SMS, and push templates migrate as content assets with field mappings documented. HTML-based templates require content refactoring to Mailchimp's template editor or a compatible HTML import. We export template content and dynamic field bindings and deliver a mapping document showing which Agillic template fields map to which Mailchimp merge tags. Visual refactoring of the template layout is not in scope.

Agillic

Recipients Export

maps to

Mailchimp

CSV Import / Mailchimp API

1:1
Fully supported

Agillic's Recipients Export feature generates a structured file of all recipient records and current field values. We use this as a baseline for full-contact migrations, reconcile against Recipient API data, and ingest into Mailchimp via the Mailchimp Marketing API Members endpoint with batch processing and dedupe by email address.

Agillic

Flows

maps to

Mailchimp

Customer Journeys 3.0

lossy
Mapping required

Agillic Flows are not exportable as portable workflow definitions. We export Flow names, associated trigger events, and step sequences as a written inventory document. The customer rebuilds equivalent automations in Mailchimp's Customer Journeys 3.0 builder, which supports email and SMS triggers, conditional branching, and time-based delays. Agillic's omnichannel Flows (push, print, paid media, POS) have no Mailchimp equivalent and are documented as requiring an alternative platform.

Agillic

Audience Data (Google/Meta)

maps to

Mailchimp

Tags or Segments

lossy
Mapping required

Agillic's real-time audience activation to Google and Meta does not have a Mailchimp equivalent. We export audience definitions and membership criteria as a written specification so the customer can recreate equivalent segments using Mailchimp's segment builder with contact properties and tag logic. The paid media activation logic requires manual rebuild within Google Ads or Meta Ads Manager using exported contact lists.

Pair-specific challenges

  • Mailchimp enforces a 30-merge-field ceiling on standard plans

    Mailchimp's standard plans cap merge fields at 30 per audience; Premium raises this to 80. Agillic's fully custom schema has no fixed ceiling and clients commonly define 40-100+ custom recipient properties. We enumerate every active recipient property during discovery and produce a consolidation plan before migration: multi-value fields become Tags, related fields are merged into single text fields, and any remaining excess fields are flagged as incompatible. If the customer exceeds Mailchimp's limit on their current plan, upgrading to Premium is required before migration or data is dropped silently.

  • Custom objects and Global Data Tables have no direct Mailchimp equivalent

    Agillic Global Data Tables store relational data (product catalogs, subscription tiers, loyalty points, enrollment records) that Mailchimp cannot represent as native objects. Custom object fields stored in Global Data Tables do not sync to Mailchimp audiences without manual process. We export Global Data Table schemas and row data, map what can be flattened into contact-level merge fields or Tags, and document the remainder. For use cases requiring relational data (e-commerce purchase history, membership tiers, property details), the customer needs either a separate data store or a Mailchimp-integrated app from the Mailchimp Marketplace.

  • Explicit opt-in reconciliation required for contacts from softer permission models

    Mailchimp requires explicit opt-in confirmation for contacts, and contacts imported from platforms with softer permission models may be legally ineligible to receive marketing emails in Mailchimp without reconfirmation. We check each contact's Agillic consent status during migration and flag contacts without explicit double-opt-in for the customer to run a reconfirmation campaign. Skipping this step risks deliverability penalties and compliance issues post-migration.

  • Flow Execution IDs and journey timelines cannot be reconstructed in Mailchimp

    Agillic's Flow Execution ID ties every Activity record to a specific campaign run, enabling full customer journey reconstruction across email, SMS, push, and events. Mailchimp's activity model shows per-contact open/click/bounce aggregates but does not expose event-level timestamps for attribution to specific automation runs. We preserve Flow Execution IDs as Tags on migrated contacts and export the full event-level Activity history from Agillic as a supplementary data file, but the timeline reconstruction capability is lost in the destination.

Migration approach

Six steps for a successful Agillic to Mailchimp data migration

  1. Discovery and recipient schema enumeration

    We audit the source Agillic instance: all active recipient properties via the Recipient API or Recipients Export, Activity Export settings (confirming Flow Execution ID is enabled in Settings > System Settings > Export > Activity Exports), Global Data Table schemas and row counts, Flow names and trigger events, and Template inventory. We check API rate limit responses during export to establish current instance thresholds and use WebDAV/SFTP Activity Export as the parallel ingestion path if API calls are throttled. The discovery output is a full field inventory, a field-limit impact assessment against Mailchimp's 30- or 80-field ceiling, and a consent-status audit for opt-in reconciliation.

  2. Field consolidation mapping and Mailchimp audience setup

    We design the Mailchimp merge field mapping based on the enumeration output. High-cardinality multi-value properties become Tags. Related numeric or date properties are merged into text fields with documented format. Properties exceeding Mailchimp's field limit are flagged as incompatible and excluded with a written justification. We configure the Mailchimp audience with the correct field names, data types, and tag taxonomy before any data is ingested. If the customer is on Mailchimp Standard or Premium, we confirm the 80-field limit is active.

  3. Consent and opt-in status reconciliation

    We extract consent status from each Agillic Recipient record and segment contacts into three groups: confirmed double opt-in (migrate as subscribed), single or soft opt-in (migrate as pending with a reconfirmation tag), and no consent record (migrate as unsubscribed or exclude). We deliver a reconfirmation campaign plan for the soft-opt-in group. Mailchimp's explicit opt-in requirement is applied before migration begins to prevent compliance issues post-migration.

  4. Recipients and activity migration

    We migrate recipient records via the Mailchimp Marketing API Members endpoint in batches, using email address as the dedupe key and applying the field consolidation mapping. Activity history (sends, opens, clicks, bounces) migrates as Mailchimp activity stats per contact. We tag contacts with their Flow Execution IDs where applicable. Global Data Table row data that can be flattened migrates as merge fields or Tags; the remainder is exported as a supplementary CSV and documented as requiring an external data store or Mailchimp-integrated app.

  5. Template and Flow inventory delivery

    We deliver a written inventory of all Agillic Templates with field mapping documentation, a Flow execution sequence document listing every Flow name, trigger, and step logic, and a Global Data Table schema export with row data. The customer uses these documents to rebuild email templates in Mailchimp's template editor and rebuild Flows in Customer Journeys 3.0. We do not rebuild Flows as code inside the migration scope. We support a post-migration review call to answer questions about the inventory documents.

  6. Cutover and validation

    We freeze writes in Agillic during the cutover window, run a final delta export of any records modified during migration, and validate contact counts, field mapping completeness, and activity stats in Mailchimp. We deliver a migration completion report showing record counts by object, field coverage against the original Agillic schema, and a list of any fields that exceeded Mailchimp's limits and were excluded. The customer signs off before Agillic access is terminated.

Most migrations complete in three to five weeks for accounts with fewer than 50,000 Recipients and fewer than 30 custom properties. Migrations with 50,000-200,000 Recipients, complex multi-property schemas requiring field consolidation decisions, or extensive Activity history exports requiring WebDAV processing move to six to nine weeks. The primary time driver is the mandatory recipient schema enumeration in Agillic, which must be completed before any field mapping design can begin.
