How long does an APTANIA CRM to Mailchimp migration take?

Most migrations land between one and two weeks for up to 5,000 contacts with clean export files and straightforward field mapping. Migrations exceeding 5,000 contacts, requiring deduplication across multiple APTANIA company relationships, or involving more than 40 custom properties that need prioritization decisions move to two to four weeks. The manual APTANIA export step is the gating factor; we cannot begin import validation until the export file is available and validated.

Do APTANIA pipeline stages and deal data migrate to Mailchimp?

No. Mailchimp has no Opportunity, Deal, or Pipeline object. APTANIA deal records with stages, monetary values, and close dates do not transfer. We export deal data as a supplementary reference CSV and deliver it alongside the migration so the customer can review it for import into a dedicated CRM if needed. The written migration inventory documents this gap explicitly so it is not missed at go-live.

Do APTANIA email automation rules migrate to Mailchimp Customer Journeys?

No. APTANIA's trigger-based email automation rules are a rules-engine configuration that does not export. We do not migrate automations as code. We deliver a written automation inventory that documents each active APTANIA rule with its trigger conditions, actions, and a recommended Mailchimp Customer Journey equivalent. The customer's admin rebuilds the automations in Mailchimp's Customer Journey builder using this documentation. We do not perform the rebuild as part of the standard migration scope.

What happens to APTANIA activity history (calls, emails, meetings, notes)?

APTANIA activity logs do not transfer to Mailchimp. Mailchimp tracks email campaign opens and clicks but does not store CRM-style engagement history such as logged calls, meeting records, or internal notes. We do not migrate activity records. We deliver a written summary of activity volume by contact for the customer's reference. If the customer needs to retain activity history, it should be migrated to a dedicated CRM separately.

What does an APTANIA CRM to Mailchimp migration typically cost?

Migrations under 5,000 contacts with clean export files land between $1,500 and $2,500. Migrations exceeding 5,000 contacts, requiring extensive deduplication, or involving merge field prioritization decisions move to $3,000-$4,500. Mailchimp subscription cost (starting at $13/month for up to 500 contacts on Essentials) sits outside the migration fee and is the customer's recurring cost. Automation rebuild documentation is included; automation rebuild in Mailchimp is not included and is handled by the customer's admin or a Mailchimp partner.

Can we keep APTANIA for sales pipeline while moving email marketing to Mailchimp?

This is a viable partial migration pattern. The customer continues using APTANIA (or migrates its pipeline and deal data to a dedicated sales CRM) for sales tracking while adopting Mailchimp as the email marketing and audience platform. We configure a data export from APTANIA on a scheduled basis to keep the Mailchimp audience in sync with new contacts added in APTANIA. The customer should evaluate whether APTANIA's per-month record ceiling accommodates ongoing dual-use before committing to this pattern.

What is the Mailchimp API rate limit, and how does it affect import?

Mailchimp's API enforces a rate limit of 500 milliseconds between requests and a batch ceiling of 5MB per request. We chunk contact imports into batches that respect both limits, using exponential backoff on 429 responses. For large audiences (over 10,000 contacts), import time extends proportionally. We do not use Mailchimp's CSV importer for large migrations because it lacks deduplication control and does not support merge field population in a single pass.

How do we handle APTANIA's 1,000-record monthly ceiling during migration?

APTANIA's Basic plan limits the account to 1,000 records per month. If the customer's total record count (Contacts plus Companies plus Deals) exceeds 1,000, we advise upgrading to a higher APTANIA plan or archiving inactive records before migration. We cannot partially export records across billing cycles without risking a mid-export ceiling breach. We flag record counts during scoping and confirm the upgrade or cleanup path before the migration begins.

APTANIA CRM to Mailchimp Migration — Field-Level Mapping & Rollback

Overview

What this migration involves

Moving from APTANIA CRM to Mailchimp is a migration from a unified customer data platform into a marketing-centric audience system. APTANIA stores Contacts and Companies relationally, supports deal pipelines and activity logging, and runs trigger-based email automation. Mailchimp organizes around Audiences and Tags with no native pipeline or deal management. We export APTANIA contacts manually through the platform's CSV tools (no API exists), deduplicate against Mailchimp's audience email addresses, and map the B2C/B2B flag and lifecycle stage to Mailchimp tags and merge fields. We do not migrate pipeline stages, deal values, activity history, automation rules, or web attribution data because Mailchimp has no equivalent objects. We deliver a written automation inventory for manual rebuild in Mailchimp's Customer Journey builder and recommend fresh web tracking configuration post-migration.

Why teams make this switch

Two sides of the same decision

Leaving

APTANIA CRM

What's pushing teams away

Pricing is not published — every deal is sales-led, which makes budget planning hard and makes comparison against transparently-priced competitors like Pipedrive or HubSpot uncomfortable for finance teams.
Small ecosystem and review footprint — G2 and SourceForge listings exist but with very few public reviews, so prospective buyers cannot easily benchmark the product against mainstream CRMs.
Narrow vertical focus on UK commercial property and similar service businesses means firms in other industries lack reference customers and have to absorb more configuration risk.
Lack of public case studies and quantified outcomes on the vendor site makes it harder for buyers to justify Aptania over an Aptean, Salesforce, or HubSpot deployment with documented ROI.
Limited marketplace of pre-built integrations relative to mainstream CRMs — connectivity beyond the documented REST API typically requires bespoke development through Aptania.

Choosing

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 APTANIA CRM objects map to Mailchimp

Each row shows how a APTANIA 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.

APTANIA CRM

Contact

maps to

Mailchimp

Audience Member

1:1

Fully supported

APTANIA Contact records map directly to Mailchimp Audience members. The email address is the primary dedupe key. We export contacts via APTANIA's manual CSV tool, parse the output, and import through Mailchimp's API with batch chunking. The B2C/B2B flag stored in APTANIA becomes a Mailchimp Tag (B2C or B2B) on each audience member. APTANIA's lifecycle stage maps to a Mailchimp merge field (LIFECYCLE_STAGE) so the customer can segment based on original CRM stage.

APTANIA CRM

Company

maps to

Mailchimp

Audience Merge Field (Company Name)

lossy

Fully supported

APTANIA Company records do not map to a native Mailchimp object because Mailchimp has no Account or Company model. We extract the company name from APTANIA Company records, match it to the corresponding Contact record by name or domain, and store it in a Mailchimp merge field (COMPANY_NAME) on the audience member. The relationship between contacts at the same company is lost post-migration; Mailchimp does not support contact-to-company lookups.

APTANIA CRM

Deal

maps to

Mailchimp

None

1:1

Fully supported

APTANIA Deals with pipeline stages, monetary values, and close dates have no equivalent in Mailchimp. Mailchimp is an audience and campaign platform, not a sales CRM. We flag Deal data as non-migratable in the data map, export it as a supplementary CSV for the customer's reference, and recommend that sales pipeline data be migrated to a dedicated CRM if the customer needs to retain it.

APTANIA CRM

Pipeline

maps to

Mailchimp

None

1:1

Fully supported

APTANIA pipeline configurations (stage names, probabilities, pipeline-to-contact assignments) do not transfer to Mailchimp. We document the pipeline structure in a written deliverable so the customer's admin can recreate it in a dedicated CRM platform if needed.

APTANIA CRM

Activity: Email, Call, Meeting, Note

maps to

Mailchimp

None

1:1

Fully supported

APTANIA activity logs (email engagements, call records, meeting history, notes) have no equivalent in Mailchimp. Mailchimp tracks opens and clicks on campaigns it sends but does not store CRM-style activity history. We do not migrate activity records; we deliver a written summary of activity volume by contact for the customer's reference.

APTANIA CRM

Custom Properties

maps to

Mailchimp

Merge Fields or Tags

lossy

Mapping required

APTANIA custom fields on Contact migrate to Mailchimp merge fields (text, number, date, or checkbox types) or Tags depending on field cardinality. Mailchimp allows up to 40 merge fields per audience. Fields with more than 40 distinct values or non-standard types migrate as Tags. The customer chooses the mapping strategy during scoping.

APTANIA CRM

User

maps to

Mailchimp

Audience Admin (Reference Only)

1:1

Fully supported

APTANIA team member records map by email to Mailchimp workspace admins. Owner assignment on contacts (which team member owns the contact in APTANIA) does not transfer to Mailchimp because Mailchimp's audience model does not support record-level ownership. Owner information is documented as a reference field for manual assignment post-migration if required.

APTANIA CRM

Email Automation Rules

maps to

Mailchimp

None (Inventory Delivered)

1:1

Not supported

APTANIA trigger-based email automation rules do not export and have no equivalent structure in Mailchimp. We provide screenshot documentation of all active automation rules during pre-migration audit, then deliver a written automation inventory that maps each APTANIA trigger to a recommended Mailchimp Customer Journey equivalent. The customer's admin rebuilds automations in Mailchimp's Customer Journey builder post-migration. We do not rebuild automations as code.

Pair-specific challenges

APTANIA has no API — migration relies on manual CSV export

APTANIA does not publish API documentation, so all data extraction requires manual in-platform export through their CSV or JSON export tools. Without an API, we cannot perform delta syncs after the initial export, automate verification against the source, or handle incremental record changes during the migration window. We document the export method used, validate exported file completeness against record counts shown in APTANIA, and advise the customer to freeze writes in APTANIA during the export-to-import window to minimize delta records.
Pipeline stages and deal data do not transfer to Mailchimp

APTANIA's deal pipeline (stages, values, close dates, associated contacts) has no equivalent in Mailchimp. Mailchimp is a marketing audience platform, not a sales CRM. We export deal data as a supplementary reference CSV but do not import it into Mailchimp because no corresponding object exists. If the customer needs to retain pipeline data, we recommend migrating it separately to a dedicated CRM (Pipedrive, HubSpot, or Salesforce) before or after the Mailchimp migration.
Mailchimp audience merge field ceiling limits custom property migration

Mailchimp allows a maximum of 40 merge fields per audience. APTANIA customers with more than 40 custom properties on Contact records must choose which fields to migrate as merge fields and which to migrate as Tags or drop. We audit custom property counts during scoping and present the trade-off options to the customer before migration begins. Fields dropped from migration are documented in the data map.
APTANIA lifecycle stage maps to a custom field, not a native Mailchimp object

APTANIA's lifecycle stage (subscriber, lead, MQL, SQL, customer) is a core segmentation property but Mailchimp has no equivalent native field. We store the original APTANIA lifecycle stage as a Mailchimp merge field (LIFECYCLE_STAGE) so the customer can segment campaigns based on it. However, lifecycle stage is not a native Mailchimp filter for automation triggers unless the customer builds a Customer Journey that evaluates the merge field value. This requires manual configuration in Mailchimp post-migration.

Migration approach

Six steps for a successful APTANIA CRM to Mailchimp data migration

Discovery and export preparation

We audit the APTANIA account for contact count, company count, custom property definitions, lifecycle stage values, active automation rules, and pipeline structure. We identify any records approaching or exceeding the 1,000-record monthly ceiling on the Basic plan and advise the customer to clean, archive, or upgrade before export. We document all active automation rules with screenshots for the rebuild inventory. We confirm the export method available in APTANIA's current UI and validate that the export format (CSV or JSON) supports the required field set.
Manual export and file validation

The customer performs the manual export from APTANIA's platform. We guide the export process, verify file completeness against the record counts documented in discovery, and check for encoding issues, truncated fields, and missing required columns. Any gaps identified in the export file are flagged before import begins. We do not have API access to APTANIA, so the customer must perform this step or grant us screen-access credentials to a guided session.
Schema mapping and merge field configuration

We map APTANIA Contact fields to Mailchimp standard fields (FNAME, LNAME, EMAIL, PHONE) and custom properties to Mailchimp merge fields or Tags. The B2C/B2B flag becomes a Tag; the APTANIA lifecycle stage becomes a LIFECYCLE_STAGE merge field. We configure merge fields in the Mailchimp audience before import begins. If custom property count exceeds Mailchimp's 40-merge-field ceiling, we present the customer with a prioritized field selection.
Contact import with deduplication

We import contacts into the Mailchimp audience using the Mailchimp API with batch chunking. The email address is the dedupe key; contacts with duplicate emails are merged rather than duplicated. APTANIA contacts that share a company name are tagged with the company name for reference segmentation. We apply the B2C/B2B tag and LIFECYCLE_STAGE merge field during import. Bounced and invalid email addresses are flagged in the import report for the customer's cleanup review.
Company name mapping and supplementary data export

APTANIA Company records are processed separately. Company names are extracted, matched to corresponding Contact records by name or domain, and stored in the COMPANY_NAME merge field on each audience member. Deal records and pipeline configurations are exported as a supplementary reference CSV and delivered to the customer with a written explanation that this data does not migrate to Mailchimp and should be reviewed for CRM replacement if retention is required.
Automation inventory delivery and cutover

We deliver the written automation inventory documenting each APTANIA trigger-based rule with its conditions, actions, and a recommended Mailchimp Customer Journey equivalent. We do not rebuild automations in Mailchimp; that work is performed by the customer's admin or a Mailchimp partner. We perform a final contact count reconciliation against the original APTANIA export and the Mailchimp audience total. Cutover is complete when the customer confirms Mailchimp is the active audience system and APTANIA is set to read-only or decommissioned.
