Overview
Agent Legend organizes contacts around a CRM-plus-AI model: every contact carries Lily's Lead Intelligence Score (0–100), a Lead Type (First-Time Buyer, Investor, Downsizer), a Persona tag, and multi-channel activity logs (SMS, email, voicemail). Mailchimp's data model centers on audiences containing contacts with merge tags, tags, and groups — it has no native equivalent for predictive scoring or behavioral personas. We migrate Agent Legend contacts as Mailchimp audience members, writing Lily scores and Lead Types into merge tag fields (Lead_Score__c, Lead_Type__c, Persona__c) that your Mailchimp segments can reference for targeting. Campaign sequences, automated outreach rules, and Circle Prospecting logic are workflow constructs that do not transfer — we export your Agent Legend sequence definitions as a rebuild reference for Mailchimp Customer Journeys. Owner resolution happens via email match against Mailchimp subscribers. Activity history (calls, emails, voicemails) is preserved as a structured notes block on each contact record so your team retains full communication context at go-live.
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 Agent Legend 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.
Agent Legend
Contact
Mailchimp
Audience Member
1:1Agent Legend contacts map directly to Mailchimp audience members. Email address serves as the primary key for de-duplication and matching between systems. Contacts that lack a valid email address are flagged during validation and excluded from the migration batch — Mailchimp requires a deliverable email for each subscriber to maintain list hygiene and deliverability standards.
Agent Legend
Lead Intelligence Score (Lily)
Mailchimp
Merge Tag — Lead_Score__c
1:1Agent Legend's Lily assigns a 0–100 Lead Intelligence Score per contact based on behavioral signals. Mailchimp does not have a native scoring field — it tracks engagement metrics like opens and clicks but not predictive intent scores. We create a Number-type merge tag (Lead_Score__c) on the target Mailchimp audience and write each contact's Lily score so you can segment by high-intent leads in future Mailchimp campaigns.
Agent Legend
Lead Type
Mailchimp
Merge Tag — Lead_Type__c
1:1Agent Legend tags each contact with a Lead Type classification such as First-Time Buyer, Downsizer, or Investor. These classifications are stored as custom properties within Agent Legend's contact record. We create a Text-type merge tag (Lead_Type__c) on the Mailchimp audience and write each contact's type for segmentation, personalization tokens, and targeted campaign routing based on property preferences.
Agent Legend
Persona Tag
Mailchimp
Merge Tag — Persona__c
1:1Agent Legend assigns behavioral Personas to contacts through Lily's data cross-referencing analysis across multiple signals. Mailchimp does not have a native persona model or behavioral classification system. We write Persona data to a Text merge tag (Persona__c) so your team can target contacts by behavioral cluster in Mailchimp automations, customer journeys, and segmented campaigns based on demonstrated buying patterns.
Agent Legend
Company / Association
Mailchimp
Merge Tag — Company_Name__c
1:1Agent Legend stores company associations as contact properties under a N:1 relationship model. Mailchimp does not have a native Company object separate from contacts. We write the primary company name to a merge tag (Company_Name__c). For contacts with multiple company associations, secondary companies are appended as a comma-separated value string within the same field for reference.
Agent Legend
Campaign / Sequence
Mailchimp
Customer Journey (export reference)
1:1Agent Legend campaign sequences and outreach automations are workflow definitions with triggers, conditions, and multi-channel actions across SMS, email, and voicemail channels. Mailchimp Customer Journeys are email-centric automations with a different trigger architecture and no support for ringless voicemail. We export your Agent Legend sequence definitions as a structured rebuild reference — including step count, trigger conditions, message content, and timing intervals — so your Mailchimp admin can recreate them in Customer Journeys.
Agent Legend
Email Activity Log
Mailchimp
Campaign Activity Note
1:1Agent Legend logs each email sent within a campaign with timestamp, owner attribution, and content reference for compliance and follow-up tracking. Mailchimp tracks campaign sends, opens, and clicks for its own sends but does not import external activity history from other platforms. We write a structured note block (Source_System_Activity__c) on each audience member capturing the most recent email activity from Agent Legend for continuity.
Agent Legend
SMS / Voicemail Activity Log
Mailchimp
Tag — SMS_Activity, VM_Activity
1:1Agent Legend tracks SMS and voicemail outreach activity per contact with timestamps and owner attribution for compliance and follow-up purposes. Mailchimp is email-primary with SMS as a paid add-on feature. We tag contacts who received SMS or voicemail in Agent Legend with Mailchimp tags (SMS_Activity, VM_Activity) so your team knows at a glance which contacts have prior multi-channel outreach history.
Agent Legend
Contact Owner
Mailchimp
Mailchimp Subscriber (matched by email)
1:1Agent Legend assigns an owner (agent or sales rep) per contact for accountability and territory management. Mailchimp does not have a native owner field — subscribers are recipients rather than assigned records. We match contacts to Mailchimp subscribers by email address for de-duplication. Owner attribution is preserved in a custom merge tag for reference purposes.
Agent Legend
Integration Source Tag
Mailchimp
Merge Tag — Source_System__c
1:1Agent Legend tracks which CRM or lead source feeds each contact with native integrations to over 500 platforms for data enrichment and lead routing. Mailchimp has no native integration-source tracking field for external acquisition channels. We write the primary lead source or CRM integration name to a Text merge tag (Source_System__c) so your team can segment Mailchimp audiences by original acquisition channel for attribution reporting.
Agent Legend
Unsubscribed / Cleaned Status
Mailchimp
Mailchimp Subscriber Status
1:1Agent Legend maintains suppression states including Unsubscribed, Cleaned, and Bounced status flags per contact for compliance and list hygiene management. These suppression states map directly to Mailchimp subscriber statuses through value-by-value mapping during migration. We preserve these suppression statuses throughout the migration process so that Mailchimp does not inadvertently re-subscribe contacts who have previously opted out, maintaining compliance and protecting your sender reputation.

Migration approach
Pre-migration audit and merge tag creation
Before data moves, FlitStack AI audits your Agent Legend contact volume, custom property count (Lead Types, Personas, Lily scores, source tags), suppression statuses, and campaign enrollment data. We deliver a merge tag creation checklist for Mailchimp (Lead_Score__c as Number, Lead_Type__c as Text, Persona__c as Text, Source_System__c as Text, etc.) so your Mailchimp admin pre-creates the fields before migration validation runs. This step also flags contacts without valid email addresses — those records are excluded from migration since Mailchimp requires a deliverable email per subscriber.
Export Agent Legend contacts and custom properties via API
FlitStack AI connects to the Agent Legend API using scoped read access and exports all contacts, custom properties, owner assignments, activity timestamps, campaign enrollment records, and suppression statuses. The export captures Lily Lead Intelligence Scores, Lead Types, Personas, engagement tiers, and source integrations as structured data. No write operations occur in Agent Legend during this phase — your team continues working normally. The export runs in batches to respect API rate limits, with a checkpoint restart capability if the export is interrupted.
Transform and map data to Mailchimp audience schema
Agent Legend contacts are mapped to Mailchimp audience members by email address (primary key). Custom properties (Lily scores, Lead Types, Personas) are written to the pre-created merge tags. Suppression statuses are translated to Mailchimp subscriber statuses (subscribed, unsubscribed, cleaned) via value mapping. Activity history (most recent email, SMS, voicemail) is written as merge tags or contact tags per the mapping plan. Owner emails are preserved in a reference merge tag. Contacts are assigned to a Mailchimp audience; if your migration requires multiple audiences (e.g., per pipeline or industry), FlitStack sequences the migration accordingly.
Sample migration with field-level validation
A representative slice of contacts (typically 200–500 records spanning different Lead Types, score ranges, and activity levels) migrates to your Mailchimp audience first. FlitStack generates a field-level validation report comparing source Agent Legend values against the destination Mailchimp merge tag values — verifying Lily score precision, Lead Type string accuracy, and suppression status mapping. Your team reviews the report and confirms the mapping plan before the full migration commits. Any merge tag configuration issues are corrected in Mailchimp before proceeding.
Full migration with delta-pickup and audit log
The full Agent Legend contact list migrates to Mailchimp with activity history and custom properties written to merge tags and tags. A delta-pickup window (24 hours post-migration) captures any new contacts or status changes that occurred in Agent Legend during the cutover. FlitStack delivers a migration audit log detailing record counts by status, merge tag fill rates, and any records that failed to migrate with reason codes. One-click rollback reverts the Mailchimp audience to pre-migration state if reconciliation uncovers issues.
