Overview
Taguchi is a permission-based email and SMS marketing automation platform centered on Subscribers, Custom Fields, List memberships, and behavioral Activity logs. Nutshell is a CRM that organizes sales data around People, Companies, and Deals with pipeline management and engagement tracking. The migration from Taguchi to Nutshell is a data-pull that requires solving several non-obvious problems: Taguchi has no bulk export endpoint, so we script cursor-based pagination over the subscriber list API; bounced subscriber flags are permanent and irreversible on Taguchi, so we quarantine or suppress them on Nutshell to protect sending domain reputation; list memberships are append-only on Taguchi, so we present a tag strategy to the customer during scoping; and custom field keys that were deleted in the Taguchi UI still persist on subscriber profiles, so we snapshot the full schema at discovery to avoid field-key collisions on Nutshell. We do not migrate Taguchi automation workflows or SMS message content; we deliver a written inventory of active workflows for the customer's admin to rebuild in Nutshell.

Object mapping
Each row shows how a Taguchi 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.
Taguchi
Subscriber
Nutshell
Person (Contact)
1:1Taguchi Subscribers map to Nutshell People records. The subscriber email becomes the Person email field; subscriber status (active/bounced/unsubscribed) maps to Nutshell's HasOptedOutOfEmail and a custom Person field taguchi_status__c for full status audit. Bounced Subscribers are quarantined or written as suppressed contacts depending on the customer's suppression strategy. We resolve organization links against the Organization mapping before inserting People records.
Taguchi
Custom Fields
Nutshell
Custom Fields (Person, Company)
lossyTaguchi key-value custom fields per Subscriber map to typed Nutshell custom fields. We snapshot the Taguchi field schema at discovery, reconstruct any fields deleted from the Taguchi UI but still present on subscriber profiles as archived fields, and create matching custom fields in Nutshell before migration. Field type mapping defaults to text for unknown key-value data; date fields, numeric fields, and boolean flags are typed correctly based on content inspection during discovery.
Taguchi
Organization
Nutshell
Company
1:1Taguchi Organizations (the owning entity linked to each Subscriber) map to Nutshell Companies. The Organization name becomes the Company name; Organization metadata becomes Company custom fields. If a Subscriber has no Organization link, we create a placeholder Company using the email domain for deduplication and linkage during the Contact import phase.
Taguchi
List Membership
Nutshell
Tags (Person)
lossyTaguchi List memberships are append-only and cannot be deleted via API. We extract the full list of List names during discovery, present a strategy to the customer (map to Nutshell Person tags, custom Person fields, or both), and write accordingly. Because Taguchi list memberships cannot be removed, the migration creates a snapshot of list associations at migration time; ongoing list management in Nutshell becomes a mutable tag strategy that the customer's team manages post-migration.
Taguchi
Cluster
Nutshell
Custom Field or Tag (Person)
lossyTaguchi Clusters identify the strongest subscriber segment association. We map this as a custom Person field (cluster_name__c) or as a Person tag depending on the customer's segmentation strategy. The customer chooses during scoping; we apply the chosen strategy uniformly across all Subscriber records.
Taguchi
Activity: Opens, Clicks, Custom Events
Nutshell
Tasks (Person)
1:1Taguchi behavioral Activities (opens, clicks, custom events) migrate as Task records on the Person. Each Activity type becomes a distinct Task subject pattern (e.g., 'Taguchi: Email Open', 'Taguchi: Link Click', 'Taguchi: Custom Event') with ActivityDate set to the original Taguchi timestamp. We preserve the event metadata (URL for clicks, event name for custom events) in the Task description field. If the activity volume exceeds 100,000 records, we use batch chunking to avoid API timeout.
Taguchi
Campaign Association
Nutshell
Custom Field (Person)
1:1Taguchi campaign associations (which campaigns a Subscriber engaged with) migrate as a custom Person field campaign_history__c storing a comma-separated list of campaign names, or as Person tags if the customer prefers tag-based segmentation. We do not create Nutshell Campaigns (a different object type) because Nutshell Campaigns are primarily for email marketing tracking rather than subscriber-level engagement history.
Taguchi
Broadcast Metadata
Nutshell
Custom Field (Person)
1:1Taguchi one-time broadcast sends (name, send date, recipient count) are written as custom Person fields or as Task records on each recipient Subscriber, preserving broadcast metadata as engagement history. We do not create Nutshell Broadcasts as standalone objects because Nutshell's Broadcast feature is part of its Marketing suite, not the standard CRM People object. The customer chooses metadata storage strategy during scoping.
Taguchi
SMS Message History
Nutshell
Tasks (Person)
1:1Taguchi SMS send history migrates as Task records on the Person with subject 'Taguchi: SMS Sent' and the message content in the Task description. Phone number fields must be present and validated on the Taguchi Subscriber record before migration; we run phone number formatting during the transform phase. If a Subscriber has no valid phone number, the SMS history record is skipped and flagged in the reconciliation report.
Taguchi
Automation Workflows
Nutshell
(Not Migrated — Written Inventory)
1:1Taguchi automation workflows and journey logic are rule-driven configurations tied to Taguchi's trigger engine. We do not migrate workflows as code. We extract a written inventory of every active Workflow including its trigger conditions, actions, delays, and audience filters, and deliver it to the customer's admin for rebuild. Nutshell Foundation and Pro do not include native workflow builders; Power AI provides AI-assisted workflow suggestions only. The customer should confirm their intended automation rebuild tool (Nutshell Power AI, Zapier, Make, or a dedicated sales engagement platform) before migration planning concludes.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Taguchi gotchas
Bounced subscriber flag is permanent without Taguchi Support
Custom fields persist on deletion and cannot be hard-deleted
List membership is append-only — no deletion via API
No publicly documented bulk export endpoint
Nutshell gotchas
Contact tier limits enforced on import
No bulk API endpoint requires paginated extraction
Email sequences not exportable via API
Foundation plan disables key sales features
Pair-specific challenges
Migration approach
Discovery and API audit
We connect to the Taguchi API and extract the full subscriber list, organization list, custom field schema (current and archived), list definitions, cluster definitions, and activity history endpoints. We identify bounced, unsubscribed, and active subscriber counts, flag any API pagination complexity, and snapshot the custom field definitions including any orphaned fields no longer present in the Taguchi UI but still tagged to subscriber profiles. We present the list membership strategy options (tags, custom field, or both) and the bounced suppressor handling approach for customer sign-off before extraction begins.
Schema design in Nutshell
We create the custom fields in Nutshell for People and Companies based on the Taguchi schema snapshot, including reconstructed archived fields. We define the field type mapping (text, number, date, boolean) based on content inspection. We configure any custom Person fields required for cluster mapping and list membership strategy. We confirm API access is enabled on the customer's Nutshell plan (required for integration-level write operations). Schema is built in the customer's live Nutshell environment or a sandbox if requested.
Extraction, transform, and validation
We extract subscribers via paginated API calls, apply the bounced suppressor flag logic, transform key-value custom fields to typed Nutshell custom fields, resolve Organization-to-Company lookups, and prepare the People and Company records for import. Activity history (opens, clicks, custom events, SMS) is extracted separately and staged for batch import. We run a validation pass comparing source record counts to extracted record counts and flag any subscribers with missing required fields (email, status) for the customer to resolve before import.
Company import first
We import Nutshell Companies first, resolved from Taguchi Organizations. Subscribers without an Organization link are assigned to a placeholder Company derived from the email domain. The Company import establishes the parent lookup required for Person records. We validate Company count against the Organization count from discovery and resolve any duplicate Organization names before insert.
Person import with suppressor handling
We import Nutshell People records in batches, setting HasOptedOutOfEmail to true for bounced subscribers and writing the original Taguchi status to a custom field. Active and unsubscribed subscribers import with standard fields and custom field values. We resolve Company lookups by name or email domain match. Any Person records with unresolved Company lookups are held in a reconciliation queue for the customer to resolve manually before activity import begins.
Activity history batch import
We import activity records (Tasks representing Taguchi opens, clicks, custom events, SMS history) in batched API calls against the resolved Person records. Each Task is linked to the correct Person via the Person's Nutshell ID, with ActivityDate set to the original Taguchi timestamp for timeline ordering. Activity volume is chunked to avoid API timeout. Any activities attached to quarantined or suppressed Persons are skipped and flagged in the reconciliation report.
Cutover, validation, and workflow inventory delivery
We freeze Taguchi writes during cutover, run a final delta migration of any records modified during the migration window, then deliver the reconciliation report. We provide the written inventory of Taguchi automation workflows with trigger, conditions, and actions documented for the customer's admin to rebuild. We support a one-week hypercare window for reconciliation issues. We do not rebuild Taguchi workflows in Nutshell; Nutshell Foundation and Pro require a third-party automation tool (Zapier, Make, or Power AI workflow suggestions) which is outside migration scope.
