Overview

What this migration involves

Unanet CRM by Cosential is a purpose-built relationship and proposal management platform designed specifically for Architecture, Engineering, and Construction firms, storing contacts, companies, pursuits, custom objects, and proposal templates within a unified record graph that reflects AEC project lifecycles. Mailchimp operates as a permission-based email marketing platform organized around subscribers, audiences, and campaign automation — it fundamentally lacks native deal tracking, proposal automation, project-based CRM concepts, or any equivalent to pursuit pipeline stages. The migration transfers Unanet contact records including name, email, phone, address, and custom field values into Mailchimp subscribers via the Mailchimp API, mapping company names to merge fields and preserving Unanet contact labels as Mailchimp tags for segmentation purposes. Pursuits, pipeline stages, probability weights, and proposal workflows have no Mailchimp counterpart — FlitStack flags these elements for manual rebuild within Mailchimp's automation tools or external systems. Activity history including calls, meetings, and notes is preserved as Mailchimp notes attached to individual subscriber records with original timestamps retained. The migration leverages Mailchimp's bulk import API with comprehensive field-level validation before final commit to ensure data integrity.

Why teams make this switch

Two sides of the same decision

Leaving

Unanet CRM by Cosential logo

Unanet CRM by Cosential

What's pushing teams away

  • Account Planning feature remains weak despite repeated user requests, leaving Business Development teams unsupported in long-term account strategy.
  • Navigation is widely criticized — convoluted search, hard-to-find dashboards, and a steep learning curve frustrate new users.
  • Double data entry is required in some workflows, particularly when integrating with financial systems or proposal tools outside the core CRM.
  • The interface is described as dated and clunky compared to modern CRM alternatives, affecting daily user experience.
  • Users report that the platform can be slow to load dashboards and reports, especially with large datasets accumulated over years.

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 Unanet CRM by Cosential objects map to Mailchimp

Each row shows how a Unanet CRM by Cosential 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.

Unanet CRM by Cosential

Contact

maps to

Mailchimp

Subscriber

1:1
Fully supported

Unanet contact records map directly to Mailchimp subscribers within a designated Audience. The primary email address field becomes the subscriber key used by Mailchimp for identification and deduplication — duplicate email addresses are flagged and surfaced for resolution before the bulk import operation begins. First name, last name, and physical address fields map to Mailchimp's standard subscriber fields without transformation required.

Unanet CRM by Cosential

Company

maps to

Mailchimp

Merge Field (COMPANY) + Tags

1:1
Fully supported

Unanet company name data migrates to Mailchimp's built-in COMPANY merge field on the subscriber record. If multiple companies are associated with a single contact record in Unanet, the primary company becomes the merge field value while additional company associations are preserved as tags formatted as 'Secondary: Company X' for reference and segmentation purposes.

Unanet CRM by Cosential

Pursuit / Opportunity

maps to

Mailchimp

NO EQUIVALENT

1:1
Fully supported

Unanet pursuits track project-based opportunities with stage, probability, and value — Mailchimp has no deal or pipeline concept. These records are exported to CSV for reference and rebuilt manually in Mailchimp's automation sequences if applicable. No automatic translation is possible.

Unanet CRM by Cosential

Custom Fields (Contact)

maps to

Mailchimp

Merge Fields

1:1
Fully supported

Unanet contact custom fields map to Mailchimp merge fields within the target Audience. Mailchimp allows up to 40 merge fields per audience — fields exceeding this limit or requiring multi-value storage are handled as tags or dropped with explicit disclosure before migration runs.

Unanet CRM by Cosential

Contact Labels / Tags

maps to

Mailchimp

Mailchimp Tags

1:1
Fully supported

Unanet contact labels such as 'Decision Maker', 'VIP Client', 'AEC Industry', or other categorization flags migrate as Mailchimp subscriber tags applied to the corresponding subscriber record. Tags are preserved exactly as named in Unanet with uppercase normalization applied for Mailchimp compatibility and searchability. Duplicate tags that would result from the migration are merged during the import process to maintain a clean tag taxonomy.

Unanet CRM by Cosential

Notes

maps to

Mailchimp

Subscriber Notes

1:1
Fully supported

Unanet contact notes and company notes migrate as Mailchimp notes attached to the subscriber record. The original timestamp and note author are appended to the note body for full traceability back to the source record. Long notes exceeding Mailchimp's 2,000-character limit per note are truncated at that boundary with a reference link included pointing to the full original text location.

Unanet CRM by Cosential

Activity History (Call/Email/Meeting)

maps to

Mailchimp

NO EQUIVALENT

1:1
Fully supported

Unanet activity logs including calls logged, emails sent, and meetings scheduled have no direct Mailchimp equivalent for this type of historical engagement tracking. Mailchimp tracks campaign engagement metrics including opens, clicks, and unsubscribes on its own timeline starting from first campaign activity. Activity history is exported as a reference CSV file rather than migrated as operational data within the Mailchimp platform.

Unanet CRM by Cosential

Proposal Templates

maps to

Mailchimp

NO EQUIVALENT

1:1
Fully supported

Unanet proposal automation binds contact and pursuit data to branded templates for submission — Mailchimp has no proposal generation or template-based document automation. Proposal templates are out of scope for migration and must be recreated in a dedicated proposal tool.

Unanet CRM by Cosential

User / Owner Assignment

maps to

Mailchimp

NO EQUIVALENT

1:1
Fully supported

Unanet users and owners assigned to contacts and pursuits have no Mailchimp equivalent — Mailchimp subscribers are not assigned to team members. Owner information is exported as a reference merge field but does not function as an assignment mechanism in Mailchimp.

Unanet CRM by Cosential

Attachment / File

maps to

Mailchimp

NO EQUIVALENT

1:1
Fully supported

Unanet file attachments (proposals, resumes, project profiles) linked to contacts cannot migrate to Mailchimp — Mailchimp does not store file attachments on subscriber records. Attachments are exported with reference paths and must be re-hosted separately or linked via merge fields pointing to a document management URL.

Pair-specific challenges

  • Mailchimp is an email marketing platform, not a CRM — pursuits and pipeline stages have no equivalent

    Unanet CRM's pursuit records carry project value, pipeline stage, probability weighting, and owner assignment tied to AEC sales cycles. Mailchimp has no deal, opportunity, or pipeline concept — subscribers are contacts for email campaigns only. We preserve pursuit name, value, and stage as reference merge fields on the subscriber record, but these fields are inert in Mailchimp automations and cannot drive conditional logic the way Unanet pipeline gates do. If your team relies on pursuit tracking for forecasting, that workflow must be rebuilt in a separate CRM or spreadsheet outside Mailchimp.

  • Mailchimp's subscriber-key constraint means duplicate emails are hard-deleted, not merged

    Mailchimp uses email address as the unique subscriber key — if the same email appears on multiple Unanet contact records (e.g., a contact associated with two companies), Mailchimp treats subsequent occurrences as duplicates and rejects them during bulk import. We surface duplicates before migration and apply a rule (most-recently-modified wins; others exported as reference CSV) so you can decide how to handle them. There is no Mailchimp native merge UI for email duplicates post-import — duplicates must be resolved before the bulk operation commits.

  • Unanet's AEC-specific proposal automation has no Mailchimp counterpart

    Unanet CRM binds contact and pursuit data to branded proposal templates using the Financial Data Connector and publishing tools — this is a core differentiator for AEC firms preparing qualifications and submittals. Mailchimp has no document generation, template binding, or proposal submission workflow. Proposal templates and the automation that populates them cannot migrate. We export proposal-related field values as reference data, but your team must select a dedicated proposal tool (Unanet Proposal Automation, or a replacement) to rebuild this capability.

  • Mailchimp's merge field limit (40 per audience) constrains custom field migration

    Unanet CRM supports unlimited custom fields on contact, company, and pursuit records, and AEC firms frequently use 20–50+ custom properties for qualifications tracking, past performance, and compliance data. Mailchimp caps each Audience at 40 merge fields. We audit your custom field inventory before migration and prioritize fields by usage frequency — fields exceeding the cap are either consolidated (multiple values joined into one field) or converted to tags with explicit disclosure. You choose the consolidation strategy before the migration plan is finalized.

  • Contact ownership and user-role assignments do not translate to Mailchimp's flat subscriber model

    Unanet CRM assigns contacts and pursuits to named users with profile-based access controls and territory assignments — this is how AEC firms route follow-ups and maintain accountability. Mailchimp has no owner-assignment model; subscribers are not assigned to team members. Owner email is migrated as a reference merge field (UNANET_OWNER) but cannot trigger Mailchimp tasks, assignments, or notifications. If owner-based accountability is critical, you need a separate CRM alongside Mailchimp or a manual routing process.

Migration approach

Six steps for a successful Unanet CRM by Cosential to Mailchimp data migration

  1. Audit Unanet contact and custom field inventory

    FlitStack AI connects to Unanet via the Compass API (Compass v1 or v2) and exports a full contact inventory including standard fields, custom fields, labels, and notes. We generate a field audit report showing field name, type, usage frequency, and blank rate for every contact property. This report drives the merge field creation plan for Mailchimp and identifies which fields exceed Mailchimp's 40-merge-field limit and require tag-based or consolidated handling.

  2. Set up Mailchimp audience and merge fields

    Before data moves, we create the Mailchimp Audience (list) and pre-configure all required merge fields based on the audit. Standard fields (FNAME, LNAME, EMAIL, PHONE, ADDRESS) are mapped automatically. Custom Unanet fields are created as Mailchimp merge fields with appropriate types (text, number, date, drop-down). Merge fields that exceed Mailchimp's limit are surfaced for consolidation or tag conversion — you approve the plan before we proceed.

  3. Map labels to Mailchimp tags and resolve duplicates

    Unanet contact labels such as Decision Maker, Industry classification, and Priority levels map directly to Mailchimp subscriber tags applied to the corresponding subscriber records. We implement a tag-per-label strategy, normalizing tag names for Mailchimp compatibility requirements including uppercase conversion and space replacement with underscores or removal. Simultaneously, we identify and flag duplicate email addresses across all Unanet contacts — applying your chosen deduplication rule with the most-recently-modified record retained and excluded duplicates exported to a reference CSV file that includes the reason for exclusion for your review and records.

  4. Run sample migration with field-level diff

    A representative slice (typically 100–500 subscribers spanning contacts from multiple companies, with varied label sets and note lengths) migrates first via Mailchimp's bulk import API. We generate a field-level diff showing source Unanet value vs. destination Mailchimp field, flagging truncation, mapping gaps, and tag assignment. You verify the output before the full run commits. This step catches merge field misconfigurations and duplicate handling before large record volumes are processed.

  5. Execute full migration with delta-pickup window

    The full contact set migrates via Mailchimp bulk import API. A delta-pickup window (typically 24–48 hours) captures any Unanet contacts created or modified during the cutover window — ensuring Mailchimp reflects Unanet's final state at go-live. Activity history, pursuit data, and proposal references are exported as supplementary CSVs. Audit log captures every operation; one-click rollback is available if reconciliation fails.
