Overview
Thunderbolt Pipeline is a cloud-based construction bid management and CRM platform built for subcontractors and contractors. It stores customer contacts, company records, bid invitation data, workforce assignments, and project relationships in a single object graph tied to your pipeline stages. Mailchimp organizes all subscriber data inside Audiences with contacts, tags, segments, and custom fields. This migration extracts your contact and company records from Thunderbolt Pipeline's CRM objects and loads them into Mailchimp audiences — mapping standard fields like email, name, phone, and address directly, while surfacing bid-related properties and custom fields that need to be recreated as Mailchimp merge fields or tags. FlitStack AI sequences the export via Thunderbolt Pipeline's API or CSV export, transforms the data shape for Mailchimp's flat contact model, and handles the audience creation, tag assignment, and suppression-list import. Workflows, automations, bid rules, workforce schedules, and project management logic in Thunderbolt Pipeline do not migrate — those are platform-native constructs that require manual rebuild inside Mailchimp's automation builder or external tools. The migration runs against scoped read access on Thunderbolt Pipeline; your team keeps working in the platform during cutover, and a delta-pickup window captures any new contacts created during the transition.
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 Thunderbolt Pipeline 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.
Thunderbolt Pipeline
Contact
Mailchimp
Audience Contact
1:1Thunderbolt Pipeline contacts migrate as Mailchimp subscribers within a target audience. Every contact record must have a valid email address to create a Mailchimp subscriber profile. Contacts lacking an email address cannot be imported and will be flagged as non-importable records before the migration run executes, allowing your team to address data gaps or exclude them from the migration batch.
Thunderbolt Pipeline
Company
Mailchimp
Contact Merge Field (Company Name)
1:1Thunderbolt Pipeline companies transform into a custom merge field labeled COMPANY on each Mailchimp contact record. Since Mailchimp lacks a native Company object, parent-company hierarchies and multi-company affiliations collapse into a single text field per contact. This flattening preserves the primary company name but loses nested corporate structure details present in Thunderbolt Pipeline.
Thunderbolt Pipeline
Bid
Mailchimp
Contact Tags
1:1Bid records have no native Mailchimp equivalent, so FlitStack AI encodes bid status, bid type classification, and award outcome as contact tags on the associated contact records. Tags follow a structured format such as 'bid_2024', 'bid_awarded', and 'bid_type_subcontractor', enabling audience segmentation by bid history within Mailchimp's tagging system.
Thunderbolt Pipeline
Bid Status
Mailchimp
Contact Tag (bid_status_*)
1:1Thunderbolt Pipeline bid statuses—Pending, Submitted, Awarded, Lost, and Declined—map to tag prefixes with a standardized format. Each contact linked to a bid receives the corresponding status tag. As bid statuses change over time, contacts accumulate multiple status tags if multiple bids are associated with their record.
Thunderbolt Pipeline
Workforce Assignment
Mailchimp
Contact Tag (role_*)
1:1Workforce and resource allocation records in Thunderbolt Pipeline encode crew roles and trade specialties as tags on the linked contact. Tags such as 'role_electrician', 'role_plumber', and 'role_foreman' enable Mailchimp audience segmentation by trade classification, preserving workforce context from the source CRM.
Thunderbolt Pipeline
Contact Phone Number
Mailchimp
Contact Phone Number
1:1Phone numbers transfer directly to Mailchimp's standard PHONE merge field without transformation. Both mobile and office phone numbers from Thunderbolt Pipeline are stored in the same field since Mailchimp does not differentiate between phone number types on contact records.
Thunderbolt Pipeline
Contact Address
Mailchimp
Contact Address Fields
1:1Thunderbolt Pipeline contact address components—street, city, state, zip, and country—map to Mailchimp's address merge fields labeled ADDR1, ADDR2, CITY, STATE, ZIP, and COUNTRY. Multi-line street addresses split on newline characters into ADDR1 for the primary line and ADDR2 for secondary address details.
Thunderbolt Pipeline
Project
Mailchimp
Contact Tag (project_*)
1:1Thunderbolt Pipeline project records linked to a contact encode as project tags using a standardized prefix format such as 'project_metro_walls' or 'project_active'. Project status indicators including active, completed, and on_hold append a secondary tag component to enable granular segmentation by project lifecycle stage.
Thunderbolt Pipeline
Compliance Record
Mailchimp
Contact Tag (compliance_*)
1:1Compliance document status and certification flags such as 'compliance_current', 'compliance_expired', and 'compliance_cert_osha' migrate as read-only tags on the contact record. These tags support re-certification reminder campaigns within Mailchimp by identifying contacts with expiring or expired credentials.
Thunderbolt Pipeline
Custom Property (Contact)
Mailchimp
Mailchimp Merge Field
1:1Thunderbolt Pipeline custom contact properties that lack a standard Mailchimp field equivalent are created as merge fields within the target audience. The merge field data type is inferred from the source property type: text properties become text merge fields, date properties become date merge fields, and numeric values become number merge fields for consistent data representation.
Thunderbolt Pipeline
Unsubscribed Contact
Mailchimp
Suppression List
1:1Contacts marked as unsubscribed or bounced in Thunderbolt Pipeline export as a Mailchimp suppression list and import separately from active subscribers. This isolation prevents accidental re-emailing of opted-out contacts while preserving the complete opt-out record in your new platform for compliance documentation and audit purposes.
Thunderbolt Pipeline
Workflow / Automation
Mailchimp
No equivalent
1:1Thunderbolt Pipeline bid notification workflows, task assignment automations, and workforce reminder rules are platform-native logic constructs with no direct Mailchimp equivalent. These workflow definitions must be reviewed and rebuilt manually using Mailchimp's automation builder or external workflow tools like Zapier or Make to replicate the original logic.
Thunderbolt Pipeline
Report / Dashboard
Mailchimp
No equivalent
1:1Thunderbolt Pipeline's bid analytics, margin reports, and workforce utilization dashboards lack a Mailchimp counterpart. While the underlying contact data migrates successfully, the reporting layer including bid-specific metrics and construction analytics must be reconstructed using Mailchimp's campaign analytics or an external business intelligence tool for ongoing visibility.

Migration approach
Document Thunderbolt Pipeline contact and bid object schema
FlitStack AI connects to Thunderbolt Pipeline via API (or CSV export if API access is restricted) and inventories all contact fields, custom properties, company records, bid records, and workforce assignments. We generate a data dictionary from your live instance, flag records without email addresses (which cannot become Mailchimp subscribers), and identify bid-status and project-tag candidates for Mailchimp segmentation. This inventory drives the merge field creation checklist and audience segmentation plan.
Design Mailchimp audience structure and tag taxonomy
Based on the schema inventory, FlitStack AI designs your target Mailchimp audience structure — whether to use one audience with tag-based segments or multiple audiences for different business units. We propose a tag taxonomy mapping Thunderbolt bid statuses, project names, trade roles, and compliance flags to Mailchimp tags. Your team approves the taxonomy before any data moves, ensuring segmentation aligns with your email campaign strategy.
Create Mailchimp merge fields and suppression list
FlitStack AI creates custom merge fields in your target Mailchimp audience via the Mailchimp API including COMPANY, JOBTITLE, BID_VALUE, AWARDED_DATE, CREATED_DATE, SOURCE_OWNER_ID, SOURCE_SYSTEM_ID, LAST_ACTIVITY, and any additional Thunderbolt custom properties requiring a dedicated field. Simultaneously, we import your Thunderbolt unsubscribed and bounced contacts as a Mailchimp suppression list before loading active subscribers, ensuring opt-out compliance is maintained at migration time and preventing accidentally re-emailing opted-out contacts.
Run sample migration with field-level verification
A representative slice of 100–500 contacts migrates first, spanning different bid statuses, project associations, and trade roles. FlitStack AI generates a field-level diff showing the source Thunderbolt field value and the resulting Mailchimp subscriber field or tag. You verify tag accuracy, merge field population, and suppression list integrity before the full run commits. This catches any value-mapping gaps or tag-prefix issues before they affect your entire contact list.
Execute full migration with delta-pickup window
The full contact export runs against Thunderbolt Pipeline, loading subscribers into Mailchimp with all tags, merge fields, and address data. A delta-pickup window (typically 24–48 hours) captures any new contacts created or updated in Thunderbolt during the cutover period. FlitStack AI logs every operation and generates an audit report showing record counts, tag assignments, and any records that failed to import with reasons. One-click rollback is available if reconciliation identifies issues post-migration.
