Overview

What this migration involves

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.

Why teams make this switch

Two sides of the same decision

What's pushing teams away

  • Tier-based send limits cap monthly email and SMS volumes, forcing growing teams to upgrade or fragment sends across campaigns.
  • Record-per-list caps (50,000 to 500,000 depending on plan) constrain large-scale audience management without a clear upgrade path for overages.
  • Small-team user limits (1 to 5 users across tiers) create collaboration bottlenecks as marketing teams scale operations.

Choosing

Nutshell

What's pulling them in

  • Lowest cost entry point among mid-market CRMs—Foundation plan starts at $13/user/month, making it accessible for teams validating CRM fit before committing.
  • Integrated sales automation and email sequencing on Pro plans without requiring a separate email marketing platform, per verified Capterra reviews.
  • Consistently praised for intuitive interface and fast onboarding, with case studies reporting 100% team adoption rates within initial deployment periods.
  • Strong customer support responsiveness cited across G2 reviews, with dedicated support tiers available on Enterprise plans.
  • Native integrations with WhatsApp, Facebook Messenger, Instagram, and Slack reduce reliance on third-party middleware for common communication channels.

Object mapping

How Marketing Star objects map to Nutshell

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

maps to

Nutshell

Lead or Contact (split by qualification)

1:many
Fully supported

Marketing 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

maps to

Nutshell

Tag or Saved Filter

lossy
Fully supported

Marketing 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

maps to

Nutshell

Note or Activity on Contact/Lead

1:1
Fully supported

Marketing 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

maps to

Nutshell

Custom Field (Contact/Lead)

1:1
Fully supported

Marketing 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

maps to

Nutshell

Contact (mobile consent fields)

1:1
Fully supported

SMS 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

maps to

Nutshell

Custom Field or Note on Contact/Lead

1:1
Fully supported

Marketing 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

maps to

Nutshell

External (not migrated)

lossy
Fully supported

Marketing 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

maps to

Nutshell

Not migrated (documented for rebuild)

lossy
Fully supported

Marketing 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.

Pair-specific challenges

  • Records missing both email and mobile phone are rejected by Nutshell import

    Marketing Star requires every contact to have at least an email or a mobile phone number, but Nutshell's native import tooling has its own field requirements that can silently drop records missing required fields. During the profiling phase we flag every record where both email and mobile_phone are null or blank, present the count to the customer, and apply the chosen remediation before any Nutshell load begins: exclude the records entirely, supply a placeholder value, or suppress the segment. This check prevents partial imports where the customer believes all records transferred but a subset was silently skipped.

  • List membership translates to tags, not native Nutshell lists

    Marketing Star Lists are the primary segmentation unit with per-list caps and independent record counts. Nutshell does not use a list-based segmentation model; instead it relies on tags, saved filters, and custom fields on Contact and Lead records. We translate list membership to tag assignments, but list-level filter logic (compound conditions, exclusions, date-based triggers) does not have a native equivalent in Nutshell and requires manual reconstruction as saved filter views or tag combinations after migration. Teams relying on complex dynamic list logic should allocate admin time post-migration for this rebuild.

  • Automation workflows do not migrate and require complete rebuild

    Marketing Star Automation Workflows are not data records; they are configuration logic that references contact properties, campaign events, and time delays. Nutshell's sales automation rules operate on deal and contact events with a different action model, and the Engagement Suite sequences are scoped to outbound email cadences. We do not migrate workflow logic. We deliver a written inventory documenting every active Marketing Star workflow: trigger, conditions, actions, and a recommended Nutshell equivalent (sales automation rule, Engagement Suite sequence, or manual process). The customer or a Nutshell partner rebuilds each workflow post-migration.

  • Annual billing on Marketing Star does not credit toward Nutshell migration

    Marketing Star offers a 20% discount for annual billing, but mid-contract migrations leave the remaining paid months unused. We note the contract end date and flag this as a cost consideration, not a migration blocker. We do not prorate, credit, or recover annual subscription fees from Marketing Star during the migration engagement. The customer should assess the remaining contract term and cancellation policy before committing to a migration timeline.

Migration approach

Six steps for a successful Marketing Star to Nutshell data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Strengths

  • Generous free tier with 5,000 emails and 100 SMS per month for 12 months.
  • AI-driven campaign analytics and performance reporting included across paid tiers.
  • Integrated multichannel reach: email, SMS, QR codes, and landing pages in one platform.
  • Responsive chat and email support praised in user reviews.
  • Simple pricing model without per-contact billing on lower tiers.

Weaknesses

  • User seat limits cap at 5 even on the highest tier, forcing teams to share credentials or upgrade awkwardly.
  • Monthly send caps (100,000 to 500,000 emails depending on tier) limit high-volume senders without overage options.
  • Record-per-list caps (50,000 to 500,000) constrain large audience segments on lower tiers.
  • Landing pages restricted to Ultimate tier, limiting the platform's utility for teams needing full-funnel ownership.

Destination

Strengths

  • Simple, intuitive interface with minimal learning curve for sales teams new to CRM
  • Per-seat pricing is transparent and predictable, with annual billing reducing monthly cost
  • Full data export tool available for all account data including backups
  • Open JSON-RPC API allows programmatic access to all core objects
  • Native multichannel engagement (email, SMS, WhatsApp) without third-party add-ons for communication

Weaknesses

  • Reporting and analytics are considered weak, requiring manual Excel exports for detailed analysis
  • No bulk API endpoint—migration requires paginated API reads that must be rate-limited carefully
  • JSON-RPC API is less common than REST, requiring custom integration code compared to standard REST CRMs
  • Add-on costs (Forms, Nutshell IQ, Email Marketing) are per-company charges that stack on top of per-seat pricing
  • Feature restrictions on entry-level plans mean teams often need mid-tier to get basic automation
