Overview
Moving from Contlo to Nutshell is a structural migration from a marketing-automation-centric platform to a sales-CRM-centric platform. Contlo organizes its data model around Contacts and behavioral Segments with event-triggered automations; Nutshell uses a Person-Account-Lead-Pipeline model optimized for sales workflow management. We extract Contlo Contacts as Nutshell People (or split qualified leads into Nutshell Leads and customers into People tied to Accounts), preserve segment tags as Nutshell custom fields, and migrate campaign event history as structured exports for the customer's admin to surface in reporting. Contlo's brand-owned AI Model does not migrate and must be re-created in the destination system from scratch. Contlo automations and journey flows are documented as a written inventory for rebuild in Nutshell; they do not migrate as executable logic.
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 Contlo 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.
Contlo
Contact
Nutshell
Person
1:1Contlo Contacts map 1:1 to Nutshell Person records. Standard properties (name, email, phone, address) map directly to Person fields. The Contlo contact's current status (subscriber, lead, customer) migrates as a custom field nut_contlo_status__c so the destination system retains the original state for segmentation and reporting. If the Contlo contact is associated with a company name, we create a corresponding Nutshell Account first and link the Person to it via the accountId reference.
Contlo
Segment
Nutshell
Custom Fields
lossyContlo Segments are behavioral groupings (abandoned cart, lifecycle stage, purchase history) stored as membership tags on each Contact. We extract segment membership and write each segment name as a Nutshell custom field on the Person record. Multi-select custom fields in Nutshell can represent contacts that belong to multiple segments simultaneously. Segment rule logic (AND/OR filter conditions) is documented separately as a written reference for the customer's admin to rebuild in Nutshell as static lists or filter views.
Contlo
Campaign (Email/SMS)
Nutshell
Person (Activity Timeline)
1:1Contlo campaign metadata (name, type, scheduled date, send status) and aggregated engagement metrics (opens, clicks, conversions) migrate as structured data linked to the Person record via custom fields and activity notes. We export campaign templates as content records for the customer to republish in Nutshell's email templates. Native Nutshell Marketing (Marketing Pro plan at $49/month) can then use these templates for outbound campaigns. Delivery logs and open/click event counts are preserved as a CSV time-series export linked to Contact IDs for reimport into reporting if needed.
Contlo
Automation (Journey Flow)
Nutshell
None
lossyContlo automations are event-triggered workflow sequences with conditional branching, time delays, and multi-step actions. Nutshell does not have an equivalent event-driven automation engine for marketing. We extract the full automation graph (trigger type, conditions, action steps, branch logic) and deliver it as a written inventory document. The customer's admin rebuilds automations in Nutshell's sales automation rules (available on Pro and above) or documents the rebuild scope for a Nutshell partner. This is not a data gap; it is an action item.
Contlo
Brand AI Model Configuration
Nutshell
None
1:1Contlo's brand-owned generative AI Model is a proprietary artifact trained on the customer's brand content, campaign history, and customer interaction data. It lives in Contlo's infrastructure and cannot be exported as a portable data artifact. When migrating out of Contlo, the customer must re-train or re-create the AI model in the destination system from scratch. We document this as a required manual step and note that Nutshell's AI feature (Nutshell IQ) is a prospecting intelligence tool, not a brand-trainable generative model. This is not a data gap; it is an exclusion from migration scope.
Contlo
Custom Properties
Nutshell
Custom Fields
1:1Contlo custom fields on Contacts migrate to Nutshell custom fields on Person. Nutshell supports text, long text, currency, date, and other field types for custom fields on Person, Account, and Lead. We map field types from Contlo to the nearest Nutshell type and create the custom fields in Nutshell before the Person import. Nutshell places custom fields inside a customFields dictionary in its API, which we reference during import. Note that Nutshell's API does not support searching by custom field values directly, which may limit post-migration programmatic segmentation compared to Contlo's native filter model.
Contlo
Voice Agent
Nutshell
None
1:1Contlo Voice Agents are AI-driven phone agents built from Contlo's library with agent configuration, voice settings, and routing logic. Nutshell has no native voice agent capability. Voice Agent configuration migrates as structured data in the written inventory for the customer to evaluate Nutshell-compatible alternatives (third-party phone integrations via Nutshell's API). The agent logic itself does not map to a Nutshell artifact and requires reconfiguration in the destination system.
Contlo
Analytics / Event History
Nutshell
Person (Activity Timeline)
1:1Event-level data (opens, clicks, conversions, purchases) exports from Contlo as a time-series CSV linked to Contact IDs. We preserve this as a structured export with Contact email as the join key, enabling the customer to import engagement history into Nutshell as custom activity records or as a linked analytics dataset. Nutshell's activity timeline on Person and Account records can display engagement history if the customer imports event data as Note records with a standardized date and description format.

Pair-specific challenges
Migration approach
Discovery and scope definition
We audit the Contlo portal for Contact volume, segment count and rule complexity, active automation count and type, campaign history and engagement event volume, custom property definitions, and any Voice Agent or AI Model configurations. We pair this with a Nutshell edition check: Foundation ($13/user/mo) covers basic contact and pipeline management; Growth ($25/user/mo) adds activity reporting; Pro ($42/user/mo) adds sales automation; Business ($59/user/mo) adds multiple pipelines and territories; Enterprise ($79/user/mo) adds unlimited pipelines and API access. The discovery output is a written migration scope document and a Nutshell edition recommendation based on the customer's feature requirements.
Schema design and custom field creation
We design the Nutshell destination schema before any data moves. This includes creating custom fields on Person to receive Contlo segment membership (one multi-select or multiple single-select fields based on segment count), custom fields for Contlo contact status, and any custom fields for campaign engagement metrics. We create Account records in Nutshell for Contlo Contacts associated with company names so that the Person-to-Account relationship is satisfied before Person import begins.
Segment and static list creation
We extract every Contlo segment's membership list (which contacts belong to each segment) and create corresponding Nutshell static Lists. We also write the segment names as Person custom field values so that segment membership is visible on each Person record in the UI. Segment rule logic is documented separately for the customer's admin to review.
Contact-to-Person migration with dedupe and reconciliation
We migrate Contlo Contacts to Nutshell Person records using email as the dedupe key. Each Person record receives its standard fields (name, email, phone, address), the custom fields carrying segment membership and contact status, and a link to the parent Account if applicable. After migration, we reconcile record counts between Contlo and Nutshell and spot-check 20-30 records for field-level accuracy before proceeding to engagement history.
Campaign and engagement history export
We export Contlo campaign metadata and engagement event history as structured CSV files linked to Contact email addresses. These files are delivered to the customer for import into Nutshell as Person activity notes or as a linked analytics dataset. We do not attempt to write engagement history directly to Nutshell's activity timeline via API because the event volume and the lack of a native campaign object make a direct mapping impractical without a custom integration layer.
Automation inventory and handoff
We deliver a written inventory of every Contlo automation with its trigger type, conditions, actions, and branch logic in a structured format. This document is the customer's blueprint for rebuilding automations in Nutshell's sales automation rules (Pro tier and above) or in a third-party automation tool. We do not rebuild automations inside the migration scope. We support a one-week hypercare window after cutover for reconciliation of any Person record issues raised during the customer's first week in Nutshell.
