Overview
Moving from Symplify Communication to Nutshell is a shift from a multi-channel marketing automation platform built for enterprise ecommerce and iGaming toward an SMB-focused sales CRM. The fundamental structural difference is that Symplify organizes around Contacts, DataDocs, Lists, and Campaigns with deep engagement metrics; Nutshell organizes around Accounts, Contacts, Leads, and Opportunities with a sales-pipeline model. We export Contacts by originalId, map List membership to Nutshell People Tags, and translate DataDocs into a written inventory of custom fields for your Nutshell admin to configure. Campaign send history and engagement events (opens, clicks, bounces) migrate as activity records. Automations, journey builders, and A/B test configurations do not migrate; we document each one so your team can rebuild in Nutshell's automation layer or accept a reset in cadence strategy.
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 Symplify Communication 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.
Symplify Communication
Contact
Nutshell
People (Contact or Lead)
1:1Symplify Contacts export by originalId with all standard fields (name, email, phone, custom properties). We land them as Nutshell People records. If the contact has no associated Account in Symplify, we create a Nutshell Account from the contact's domain or company name and link via the account_id field. Nutshell People API does not support searching by custom field value, so we pre-validate all custom property mappings during discovery rather than at import time.
Symplify Communication
DataDocs
Nutshell
Custom Fields on People/Account
lossyDataDocs store relational records (purchase history, event bookings, wallet data) linked to Contacts by originalId and Document Type. We export each Document Type and translate it into a custom field on the corresponding Nutshell People or Account object. If a Document Type defines a JSON Schema, we flatten the schema into separate custom fields. Orphaned DataDocs without a defined Document Type are flagged during discovery and excluded from migration pending customer audit. DataDocs without a direct Nutshell equivalent are written to a JSON blob stored as a long-text custom field for manual extraction.
Symplify Communication
List
Nutshell
People Tags
1:1Symplify Lists are static contact groupings. We export list membership by originalId and recreate the list structure as Nutshell People Tags. Each tag maps from the Symplify list name. Dynamic segments (rules-based groupings) do not migrate as dynamic rules; we export the snapshot membership as static tags and document the segment criteria so the customer can rebuild as a Nutshell saved filter if needed.
Symplify Communication
Campaign
Nutshell
Activity Log on People + CSV inventory
1:1Symplify Campaigns represent email or messaging sendouts with metadata (name, send date, channel). Campaign metadata migrates as an activity log entry on each recipient People record in Nutshell. Campaign content (body, subject, template) is not imported into Nutshell's native content library but is delivered as a structured CSV inventory with campaign name, send date, channel, and recipient count so the customer's admin can reference historical campaign themes.
Symplify Communication
Message (per-campaign sendout)
Nutshell
Campaign Name reference in Activity Log
1:1Symplify Messages are individual sendouts within a campaign. We associate each send event (Sents) with the corresponding People record in Nutshell. If the customer needs campaign-message attribution in Nutshell's reporting, we document the campaign-message hierarchy in the CSV inventory and recommend creating Nutshell Campaigns as a reporting container after migration.
Symplify Communication
Opens
Nutshell
Activity Log entry (custom type: Email Opened)
1:1Open events export from Symplify with timestamp and message_id. We create a custom activity type entry on the People record in Nutshell with the open timestamp. Because Nutshell's native activity timeline supports calls, emails, meetings, and tasks without a native open event type, we use a note-style activity with a custom activity type label to preserve the engagement signal.
Symplify Communication
Clicks
Nutshell
Activity Log entry (custom type: Link Clicked)
1:1Click events export with timestamp, URL, and message_id. We create activity log entries on the People record in Nutshell with the clicked URL preserved in the notes field. URL-level click attribution is preserved in the exported click log CSV for reference.
Symplify Communication
Sents
Nutshell
Activity Log entry (custom type: Email Sent)
1:1Sent records track every dispatch per contact per message with delivery timestamp. We create an activity log entry on the People record marking the send event. Delivery status (delivered, bounced) is preserved as a custom field on the activity entry.
Symplify Communication
Hard Bounces
Nutshell
People suppression flag + Hard Bounce field
1:1Hard bounce records mark permanently undeliverable email addresses. We export hard bounce status by originalId and apply a suppressed flag on the People record in Nutshell. The hard bounce timestamp is preserved as a custom field. Suppressed contacts are excluded from any post-migration email campaigns in Nutshell to protect deliverability.
Symplify Communication
Soft Bounces
Nutshell
People field (Soft Bounce flag + last bounce date)
1:1Soft bounce records indicate temporary delivery failures. We export soft bounce events and apply a soft bounce flag on the People record in Nutshell. The last soft bounce timestamp and bounce code are preserved as custom fields. Soft bounce codes vary between Symplify and Nutshell's receiving infrastructure, so we document the code translation map during discovery.
Symplify Communication
Optouts
Nutshell
People: email opt-out flag
1:1Optout records track unsubscribe preferences with timestamps. We export all optout events and apply HasOptedOutOfEmail = true on the People record in Nutshell. Unsubscribe timestamp is preserved as a custom field. This ensures compliance with unsubscribe requests post-migration and prevents accidental re-sending to suppressed contacts.

Migration approach
Discovery and Symplify audit
We audit the Symplify account across all exported object types: Contacts, DataDocs, Lists, Campaigns, Messages, Opens, Sents, Clicks, Hard Bounces, Soft Bounces, and Optouts. We identify the full history window to be migrated, assess Document Type coverage for DataDocs, and estimate the number of 2-week batch export windows required for multi-year histories. We also capture custom property names, data types, and any JSON Schema definitions on DataDocs for the Nutshell field mapping phase.
Nutshell field mapping and schema design
We design the Nutshell destination schema: provisioning custom fields on People and Account objects to receive DataDoc attributes, defining tag names for List migrations, and creating custom activity types for engagement events (Email Opened, Link Clicked, Email Sent). We run a dry-run import into a Nutshell test account to validate field type compatibility and confirm that all custom fields appear correctly on the People record layout. Any fields that cannot map directly are flagged and resolved before the production migration.
Symplify batch export sequencing
We execute Symplify batch exports in 2-week chronological windows starting from the earliest record in scope. Each batch is tracked via batchId polling, and results are accumulated in a staging layer. After each batch completes, we deduplicate any records that span window boundaries and validate record counts against our discovery estimates. If any batch fails or times out, we re-request that window before proceeding to the next.
Contact, Account, and List migration
We migrate Contacts first, resolving each to a Nutshell Account by domain or explicit company name field. List membership is translated to People Tags on each Contact record. All Contacts receive their DataDoc custom fields where Document Types were fully defined. Contacts with bounce or optout flags receive suppression flags before any send activity is imported. The People import uses Nutshell's bulk import endpoint with row-level error reporting so we can isolate and retry failed records.
Engagement history migration
We migrate Sents, Opens, Clicks, Hard Bounces, and Soft Bounces as activity log entries against the corresponding People records. Each activity entry includes the original timestamp, channel, and any available metadata (message ID, URL, bounce code). Activity import uses Nutshell's People API with the activity endpoint, chunked to avoid oversized payloads. After each engagement batch, we reconcile activity counts against the Symplify export totals to confirm completeness.
Cutover, validation, and automation handoff
We freeze Symplify writes during the cutover window, run a final delta migration of any records modified since the last export window, and enable Nutshell as the system of record. We deliver the campaign and journey inventory document, the DataDoc field map, and a reconciliation report showing record counts by object in both systems. We support a 5-business-day hypercare window for data discrepancies. Nutshell automations, sales sequences, and reporting dashboards are not rebuilt as part of the migration scope.
