Overview

What this migration involves

Cronberry and Nutshell serve overlapping segments of small B2B teams but differ fundamentally in data architecture. Cronberry uses a flat Contact model with segment and tag associations, stores omnichannel campaign data across Email, SMS, Push, and WhatsApp channels, and lacks a publicly documented REST API, making migration contingent on Cronberry's export utilities and direct database access. Nutshell uses a People and Company model with a standard pipeline-driven Opportunity object, built-in email marketing, and a documented REST API. We extract Cronberry's contact and campaign data in dependency order, flag duplicate records during scoping, preserve behavioral event history as Activities in Nutshell, and document every Cronberry Smart Segment and automation for the customer to rebuild manually in Nutshell's workflow builder. Landing Pages, rendered form layouts, and channel authentication credentials do not migrate as structured data.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Cronberry

What's pushing teams away

  • Recent UI overhaul shipped without user training or documentation, leaving teams unable to locate features and wasting money on leads they cannot manage.
  • Repeat-contact detection and contact naming conventions are described as confusing and broken by multiple reviewers, creating duplicate records in the CRM.
  • Facebook and Google Ads remarketing are absent, forcing teams to manage paid acquisition and retargeting in separate platforms.
  • Customer support responsiveness drops significantly after purchase according to negative reviews citing unanswered calls and emails.
  • No publicly documented API limits or bulk export capability, making data portability a manual and error-prone process.

Choosing

Nutshell logo

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 Cronberry objects map to Nutshell

Each row shows how a Cronberry 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.

Cronberry

Contact

maps to

Nutshell

Person (Contact)

1:1
Fully supported

Cronberry Contact records map to Nutshell People. We preserve name fields, email, phone, and address data directly. Cronberry tags and segment memberships map to Nutshell People Tags. Repeat-contact deduplication is applied during scoping: we match on email, name, and phone, generate a deduplication report for the customer to approve, and suppress or merge duplicates before import. Cronberry's custom contact fields map to Nutshell custom fields on Person, which are available from the Foundation tier onward.

Cronberry

Company

maps to

Nutshell

Company

1:1
Fully supported

Cronberry Company-level data (where present) maps to Nutshell Company records. Field-level mapping is required because Cronberry's company schema varies by implementation and may include custom properties. Company names and domains migrate directly; any custom fields require a Nutshell custom field created before the import phase begins.

Cronberry

Campaign

maps to

Nutshell

Campaign

1:1
Fully supported

Cronberry Campaign records carry channel information (Email, SMS, Push, WhatsApp), timing rules, and target segment assignments. We extract campaign names, status, start and end dates, and channel type. Campaign performance metrics (open rates, click rates, send volumes) migrate to Nutshell Campaign custom fields because Nutshell's standard Campaign object tracks cost, status, and type without native performance metrics beyond members. Segment associations are documented separately for rebuild in Nutshell's list builder.

Cronberry

Smart Segment

maps to

Nutshell

People Tag (reconstruction)

lossy
Fully supported

Cronberry Smart Segments are built from conditional rules against contact field values. These rules are not exported as a reusable schema. We reverse-engineer each segment by querying which contacts belong to it, then document the implied conditions so they can be reconstructed manually in Nutshell using its People Tags and filter-based list feature. The customer receives a written segment map with field names, operators, and values per original Cronberry Smart Segment.

Cronberry

Form (Drag-and-Drop Builder)

maps to

Nutshell

Form (Field Schema)

lossy
Fully supported

Cronberry Form definitions including field structure, conditional logic, and submission targets are extractable as a field schema. We map form field labels and types to Nutshell form fields. Visual drag-and-drop layout and conditional branching rules cannot be preserved 1:1 and must be rebuilt manually in Nutshell's form builder. The customer receives a field inventory per original form to guide the rebuild.

Cronberry

User/Agent

maps to

Nutshell

User

1:1
Fully supported

Cronberry User and agent records map to Nutshell Users. We match by email address and migrate display name, role, and basic identity. Cronberry's permission and role structures differ significantly from Nutshell's user roles (Admin, Manager, Standard), so we migrate identity only and defer permission configuration to the customer during Nutshell setup.

Cronberry

Event Log / Behavioral Tracking

maps to

Nutshell

Activity

1:1
Fully supported

Cronberry tracks behavioral events (email opens, clicks, push interactions, SMS replies) against contact records. We map these to Nutshell Activities with the event type recorded in the Activity description or a custom field. Nutshell Activities appear in the Person and Company timelines. Event schema may require field mapping because Cronberry's behavioral event properties do not map directly to Nutshell's Activity object fields; we document the mapping per event type during scoping.

Cronberry

Template (Email, SMS, Push)

maps to

Nutshell

Template (Email Template, Sequence Step)

1:1
Fully supported

Message templates with personalization variables are migratable from Cronberry. We extract template content and variable placeholders, then map them to Nutshell's Email Template format or Sequence Step content depending on the intended use. Rich formatting and HTML structure may require adjustment because the two platforms use different rendering engines. The customer reviews template output in Nutshell's preview before finalizing.

Cronberry

Channel Configuration (Email, SMS, Push, WhatsApp)

maps to

Nutshell

Channel Re-registration (External)

lossy
Fully supported

Cronberry's multi-channel setup stores channel credentials and sender configurations (API keys, sender IDs, verified domains). These credentials cannot be transferred to Nutshell. We document the original channel configuration as a checklist so the customer's admin can re-register sender domains, verify email sending domains in Nutshell, and reconfigure SMS sender IDs through Nutshell's Twilio integration or their own SMS provider. This is a manual reconfiguration step outside the data migration scope.

Pair-specific challenges

  • Cronberry has no documented public REST API

    Cronberry does not publish API documentation for programmatic data access. The GitHub repositories contain only client-side webpush SDKs, not a full REST API. We handle this by requesting structured CSV or JSON data dumps through Cronberry's internal export tools or direct database access where available, coordinated with Cronberry support before migration begins. If Cronberry cannot provide a structured export within the project timeline, we extract from any available UI-based export with manual field mapping. This adds scope and risk that teams switching to API-first platforms like Nutshell should understand upfront.

  • Cronberry Smart Segment logic cannot be exported directly

    Cronberry Smart Segments are defined by conditional rules against contact field values, but these rules are not included in Cronberry's export. We reverse-engineer segment membership by querying which contacts belong to each segment from the export data, then document the implied field-value conditions so they can be rebuilt manually in Nutshell's filter-based People list feature. This produces a written segment map, not a programmatic migration, and the customer must rebuild segments in Nutshell's UI.

  • Cronberry contact deduplication is unreliable

    Cronberry's repeat-contact deduplication is broken by multiple reviewer accounts, and the field naming for contact matching is confusing. This means a single physical contact may exist as multiple records in Cronberry. We identify probable duplicates during scoping by matching on name, email, and phone, and present a deduplication report to the customer for approval before importing into Nutshell. Without this pass, Nutshell will import duplicates, creating a data quality problem that mirrors the source problem.

  • Cronberry automations and workflows do not migrate

    Cronberry Workflows built in the campaign workflow builder cannot be exported as reusable automation code. We deliver a written inventory of every active Cronberry automation with its trigger conditions, action sequence, and recommended Nutshell automation equivalent (Nutshell Automation Rules or Sequences add-on). Landing Pages and rendered form layouts similarly do not migrate as structured data. The customer rebuilds these assets manually in Nutshell's builder after migration completes.

Migration approach

Six steps for a successful Cronberry to Nutshell data migration

  1. Export coordination and scoping discovery

    We request structured data exports from Cronberry through their internal tools or direct database access, coordinated with Cronberry support. We audit the export scope across Contacts, Companies, Campaigns, Segments, Forms, Users, Event Logs, and Templates. We identify any data not included in the export and flag high-priority gaps such as custom fields, behavioral event history, and segment membership data. The scoping output is a written data inventory and a confirmation of what will and will not migrate from the source account.

  2. Deduplication pass and segment reverse-engineering

    We run deduplication against the Cronberry export using email, name, and phone as match keys. We generate a deduplication report presenting probable duplicate pairs and counts, which the customer reviews and approves before we suppress or merge duplicates. Simultaneously, we reverse-engineer Cronberry Smart Segment membership by querying which contacts belong to each segment, inferring the conditional rules from the contact data, and documenting the implied conditions as a written segment map for rebuild in Nutshell.

  3. Nutshell schema design and custom field creation

    We design the destination schema in Nutshell before any data import. This includes creating any custom fields on Person and Company to receive Cronberry custom contact properties, designing People Tags to mirror Cronberry tag and segment structure, mapping Cronberry campaign data to Nutshell Campaign records with custom performance fields, and configuring any Nutshell Automation Rules to be mapped from the Cronberry automation inventory. Nutshell's Foundation tier supports custom fields, which covers most migration requirements at the lowest price point.

  4. Data import in dependency order

    We import data into Nutshell in dependency order: Companies first (from Cronberry Company records), then People (Contacts with tag associations resolved), then Campaigns (with segment associations documented), then Activity history (behavioral events mapped to Nutshell Activities), then Templates (email and SMS content). Each phase emits a row-count reconciliation report before the next phase begins. User records are matched by email and held in a reconciliation queue for any missing Nutshell User accounts to be provisioned by the customer.

  5. Channel re-registration and template review

    We deliver a channel re-registration checklist documenting Cronberry's original sender domains, SMS sender IDs, and push notification credentials so the customer's admin can reconfigure these in Nutshell or their own provider. We also deliver migrated email and SMS templates in Nutshell's template format for customer review and formatting adjustment before use in live campaigns.

  6. Automation rebuild handoff and validation

    We freeze writes on the source data during cutover, run a final delta migration of any records modified during the migration window, then hand off. We deliver the written automation inventory and segment map to the customer's admin for rebuild in Nutshell's Automation Rules or Sequences add-on. We support a three-day hypercare window to resolve reconciliation issues identified in the first week of Nutshell usage. We do not rebuild Cronberry automations as Nutshell automation code inside the migration scope.

Strengths

  • Multichannel outreach in a single subscription covers Email, SMS, Push, WhatsApp, and In-App messaging.
  • Lowest entry price among comparable marketing automation platforms at $25/month usage-based.
  • Drag-and-drop form and landing page builders require no coding to create lead capture assets.
  • Lead management with caller assignment and follow-up tracking consolidates sales engagement workflows.

Weaknesses

  • No publicly documented REST API means migration must rely on manual exports or undocumented endpoints.
  • Recent UI redesign shipped without training materials, creating a known onboarding gap for existing customers.
  • Contact deduplication and naming conventions are unreliable, leading to duplicate record issues post-import.
  • Absence of Facebook and Google Ads remarketing integration forces teams to split paid media management across platforms.
  • Customer support responsiveness declines sharply after purchase based on negative review patterns.

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

Most migrations land between one and three weeks for accounts under 15,000 Contacts with clean company data and no complex behavioral event history. Migrations involving large event histories (over 100,000 activity records), multiple Cronberry workspaces, or extensive Smart Segment reverse-engineering extend to three to five weeks because of the manual export coordination and deduplication pass required before import.
