Overview
Moving from Marketing Star to Nutshell is a structural migration from a marketing automation platform to a CRM. Marketing Star organizes data around Contacts and Lists with campaign-level tracking; Nutshell uses the Lead-Contact-Account-Deal model with pipeline management as its primary object. We validate every Marketing Star contact record for email or mobile phone before loading into Nutshell, apply the missing-field remediation the customer chooses during scoping, and resolve the list-to-tag translation so that original audience segments are recoverable post-migration. SMS opt-in status migrates as a separate consent field rather than a note. Automation workflows and sequences are not migrated as code; we deliver a written inventory of every active workflow with a Nutshell equivalent recommendation and the customer or a Nutshell partner rebuilds them post-cutover. Landing page content and URL redirect configurations are exported as static documentation because Nutshell does not host landing pages natively.
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.

Object mapping
Each row shows how a Marketing Star object lands in Nutshell, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Marketing Star
Contact
Nutshell
Lead or Contact (split by qualification)
1:manyMarketing Star Contacts with no purchase history or campaign engagement map to Nutshell Lead. Contacts with deal associations, multiple campaign touches, or explicit sales qualification signals map to Nutshell Contact and may be attached to an Account if a company record exists in Marketing Star. We compute the split using Marketing Star's contact_score and last_activity_date properties during the scoping phase. Records without an email address and without a mobile phone number are flagged in the profiling report and excluded or remediated before any Nutshell load.
Marketing Star
List
Nutshell
Tag or Saved Filter
lossyMarketing Star Lists are the primary segmentation unit; each list has a defined record cap per tier. We export list membership as a contact-to-list association table, then create equivalent Nutshell tags (one per source list) and apply them as multi-select tag assignments on each Contact or Lead. List-level filters are translated to Nutshell saved filter views as a secondary segmentation layer. If the original audience was constructed from multiple nested lists, we reconstruct the combined view as a tag-based filter in Nutshell.
Marketing Star
Campaign
Nutshell
Note or Activity on Contact/Lead
1:1Marketing Star Campaigns (email, SMS, QR code) are exported with campaign name, send date, channel type, and summary metrics (opens, clicks, sends). We create a Note on each impacted Contact or Lead containing campaign name, channel, send date, and key performance indicators. Campaign-level reporting metrics (open rate, click rate, bounce rate) are stored in a Nutshell custom field or attached as a CSV export reference so that campaign performance history is accessible post-migration without a separate reporting tool.
Marketing Star
Form
Nutshell
Custom Field (Contact/Lead)
1:1Marketing Star Form submissions populate contact properties. We export the form field structure and field-to-contact-property mappings, then pre-create equivalent custom fields on the Nutshell Contact or Lead object before migration. Form submissions without a corresponding contact record in Nutshell are held in a queue for the customer to reconcile or suppress. Note that Nutshell does not have a native form builder equivalent; the form intake logic is replaced by a separate form tool or Nutshell's web-to-lead functionality.
Marketing Star
SMS Contact
Nutshell
Contact (mobile consent fields)
1:1SMS contacts are distinguished in Marketing Star by mobile phone number and a separate opt-in flag. We preserve the mobile phone number and SMS consent status as distinct Nutshell custom fields (e.g., sms_mobile_phone__c and sms_opt_in_date__c) on the Contact or Lead record. The original SMS opt-in source (form, keyword, QR scan) is stored in a metadata field for compliance verification in Nutshell. Nutshell's Engagement Suite SMS capability is the destination for 1:1 SMS messaging after migration.
Marketing Star
QR Code
Nutshell
Custom Field or Note on Contact/Lead
1:1Marketing Star QR codes are tied to campaigns or forms and track physical-to-digital attribution. We export QR code metadata (campaign association, redirect URL, creation date) and store it as a custom field group or Note on the Contact or Lead record that was attributed through the QR scan. The QR redirect URL is preserved in a custom field for reference. Teams that rely on QR scanning as a primary attribution channel should confirm with Nutshell whether the Engagement Suite web tracking or a separate QR analytics tool will replace this function.
Marketing Star
Landing Page
Nutshell
External (not migrated)
lossyMarketing Star Landing Pages are available on the Ultimate tier ($500/month) and contain content, form integrations, and URL redirect configurations. Nutshell does not host landing pages. We export page content, URL redirects, and form field configurations as a static documentation package (HTML export and URL mapping table). The customer or a web implementation partner recreates these in a landing page tool of choice. Landing page traffic attribution does not migrate as CRM data.
Marketing Star
Automation Workflow
Nutshell
Not migrated (documented for rebuild)
lossyMarketing Star Automation Workflows (property-triggered sequences with delays and CRM actions) have no direct equivalent in Nutshell's automation model. Nutshell Pro and above offer sales automation rules and the Engagement Suite provides email sequences, but the trigger conditions, action types, and branching logic differ significantly. We do not migrate workflows as code. We deliver a written inventory of every active workflow with its trigger event, conditions, actions, and a recommended Nutshell automation equivalent, and the customer's admin rebuilds them post-migration.

Migration approach
Data profiling and field validation
We extract all Marketing Star contact records, lists, campaigns, forms, and SMS contact metadata. We run the email-or-mobile-phone validation check across the full contact set and generate a remediation report listing every record missing both fields. We inventory all custom contact properties, list names, active workflows, and campaign metadata before presenting the scoping report to the customer. This phase determines whether the migration qualifies for the short or long timeline bracket and identifies any list-splitting requirements due to Marketing Star tier caps.
Tag architecture design and custom field pre-creation
We design the Nutshell tag namespace to match the Marketing Star list structure (one tag per source list, with optional tag prefixes for list category grouping). We pre-create all required Nutshell custom fields on Contact and Lead: SMS mobile phone, SMS opt-in date, SMS opt-in source, campaign performance summary fields, and any custom contact properties from Marketing Star forms. Custom fields are deployed into a Nutshell Sandbox org first for validation before any production data loads.
Sandbox migration and reconciliation
We run a full migration into the Nutshell Sandbox using production-equivalent data volume. The customer's admin reviews record counts (Contacts loaded, Leads loaded, tags applied per contact, SMS consent fields populated), spot-checks 25-50 randomly selected records against the Marketing Star source, and confirms the tag architecture matches the original list logic. Any field mapping corrections, tag naming adjustments, or custom field additions happen in this phase before production migration begins.
Campaign metadata and landing page documentation export
We export all Marketing Star campaign names, send dates, channel types, and summary metrics (open rate, click rate, send volume) as a structured CSV and reference sheet. Landing page content, URL redirects, and form configurations are exported as static HTML and URL mapping documentation. Both deliverables are handed off to the customer before or on cutover day, not migrated as live data.
Production migration in dependency order
We run production migration in record-dependency order: custom fields and tags first, then Contacts and Leads (with the email-or-mobile remediation applied and tag assignments applied per source list membership), then SMS consent records, then campaign metadata attached to each contact record. Lists are not recreated as separate Nutshell objects; their membership is preserved as tag assignments on each contact. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and automation rebuild handoff
We freeze writes in Marketing Star during the cutover window, run a final delta pass for any records modified during migration, then enable Nutshell as the system of record. We deliver the workflow inventory document and campaign documentation package to the customer's admin team with a recommended rebuild sequence for the highest-priority automations. We support a one-week hypercare window for reconciliation issues. Rebuilding Marketing Star workflows as Nutshell automation rules or Engagement Suite sequences is outside the standard migration scope and requires a separate engagement or internal admin work.
