Overview
Moving from ELAINE to Nutshell is a platform-type transition from an email marketing and automation tool to a sales-focused CRM. ELAINE organizes data around subscriber Contacts and Target Group segmentation for campaign targeting; Nutshell organizes data around People, Companies, Leads, and Deals for pipeline management. We map ELAINE Contacts to Nutshell People, preserve Target Group membership as tag or custom field data on each Person record, and convert Email Campaign send history into Activity notes. We do not migrate Mail Sequences as automation logic because Nutshell does not have an equivalent sequence engine. We do not migrate workflows, A/B test logic, or transactional email configurations as code; we deliver a written inventory of each for the customer's admin to evaluate for rebuilding in Nutshell's workflow tool. Custom field types from ELAINE require type conversion mapping before insert into Nutshell's custom field schema.
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 ELAINE 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.
ELAINE
Contact
Nutshell
Person
1:1ELAINE Contacts migrate to Nutshell People as the primary record. We map standard properties (email address, name fields, phone, address) to their Nutshell equivalents and preserve any enrichment data added via the ELAINE API as read-only custom fields on the Person record. The Person record is the primary entity; all other records (Companies, Activities) link back to it.
ELAINE
Contact
Nutshell
Company
1:1When an ELAINE Contact record contains a company name or domain field, we extract that value and either match it against an existing Nutshell Company record or create a new Company during migration. The Person record in Nutshell receives the Company as a lookup reference. This produces the People-attached-to-Accounts structure that Nutshell's CRM model relies on for pipeline reporting.
ELAINE
Target Group
Nutshell
Tag
lossyELAINE Target Group memberships are flattened into Nutshell Tags on the Person record. Each Target Group name becomes a Tag value, and the Contact's membership in that group is recorded as a tag assignment. Complex nested Target Group hierarchies require flattening during the transform phase; we document the full group tree before migration and note any nested relationships that cannot be preserved as a flat tag structure in Nutshell.
ELAINE
Target Group
Nutshell
Custom Field (Multi-Select)
lossyAlternatively, if a customer's Target Group model uses fixed group names rather than dynamic membership, we offer migration as a multi-select custom field on Nutshell Person. The customer chooses between tag-based and custom-field-based segmentation during scoping. Multi-select fields support up to 500 values in Nutshell; we flag if the group count exceeds this limit.
ELAINE
Email Campaign
Nutshell
Activity (Note)
1:1ELAINE Email Campaign records—newsletter sends, transactional emails, and A/B test variants—migrate to Nutshell Activity notes on the Person record. Each campaign generates a note entry containing the campaign name, send date, subject line, and open/click metadata where available. Nutshell does not have a native Campaign object; this activity-note pattern preserves campaign context on the Person timeline without requiring a custom object.
ELAINE
Custom Field
Nutshell
Custom Field
lossyELAINE custom fields on Contacts (text, choice, date, and calculated fields) require type mapping to Nutshell's supported custom field types: Text, Long Text, Currency, Date, Number, and Dropdown. Calculated fields from ELAINE have no direct Nutshell equivalent; we flag them during discovery and document the calculation logic so the customer's admin can replicate it as a formula field or manual process in Nutshell. All custom field definitions are pre-created in Nutshell before any Person records are imported.
ELAINE
Attachment
Nutshell
External File Reference
1:1Files attached to ELAINE Contacts or campaigns are downloaded during extraction, stored locally, and re-linked to the corresponding Nutshell Person record via a file reference field or documented upload instruction. We do not store files in Nutshell's native storage during migration; we deliver the file package and a mapping spreadsheet that tells the admin which files belong to which Person record for re-upload post-migration.
ELAINE
Mail Sequence
Nutshell
Written Automation Inventory
lossyELAINE Mail Sequences with multi-step triggers, delays, and conditional branches do not migrate as automation code. Nutshell's workflow tool handles task creation and field updates, not email cadence sequences. We extract every Mail Sequence definition (step order, trigger condition, delay duration, content block, A/B variant) and deliver it as a written automation inventory document with a Nutshell Workflow equivalent recommendation for each step. The customer's admin rebuilds sequences manually in Nutshell or a connected sales engagement tool.
ELAINE
API Integration
Nutshell
Integration Documentation
lossyExternal API integrations that enriched subscriber data in ELAINE (GDPR-compliant enrichment providers, data append services, webhook endpoints) are documented as a written integration inventory. We capture the endpoint configuration, data flow direction, and trigger conditions for each integration so that the customer's admin can re-establish these connections in Nutshell's webhook or Zapier ecosystem post-migration. We do not configure the new integrations inside the migration scope.

Migration approach
Discovery and API access scoping
We audit the ELAINE account for accessible export endpoints, Contact volume, Target Group count and hierarchy depth, active Mail Sequences, Email Campaign volume, and custom field schema. If the ELAINE plan lacks API access, we scope CSV export coverage and identify any objects requiring manual extraction. We also confirm the Nutshell account status, plan tier, and existing People, Company, and custom field structure. The discovery output is a written migration scope with a confirmed object inventory and export method for each object.
Schema design and tag strategy decision
We design the Nutshell destination schema including custom fields (mapped from ELAINE custom field types), any required Company records to satisfy Person lookups, and the tag strategy for Target Group membership. The customer chooses between tag-based and custom-field-based segmentation during this phase. We pre-create all custom fields in Nutshell before any data import. Mail Sequence definitions are extracted and structured into the written automation inventory during this phase.
Data extraction and transformation
We extract Contacts, Target Group memberships, Email Campaign records, Custom Field definitions and values, and Attachments from ELAINE using available export endpoints or CSV workflows. We transform the data into Nutshell-compatible format: Target Group memberships become tag assignments or custom field values, calculated fields are flagged with their formula documentation, and campaign send history is structured as activity note content. We resolve any dirty data issues (duplicate email addresses, missing required fields) and flag them for customer review before import.
Sandbox migration and reconciliation
We run a full migration into the customer's Nutshell sandbox environment using production-like data volume. The customer's team reconciles record counts (People in, Companies in, Activity notes in), spot-checks 20-30 random records against the ELAINE source, and reviews the tag and custom field assignments. Any mapping corrections and custom field type conversions are finalized here before production migration. The Mail Sequence inventory is also reviewed during this phase.
Production migration in dependency order
We run production migration in record-dependency order: Companies first (to satisfy Person lookup references), then People with tag assignments and custom field values, then Activity notes for campaign history. Attachments are packaged with a mapping file for manual re-upload post-migration. Each phase emits a row-count reconciliation report. We use Nutshell's API with rate-limit handling and batch chunking to manage import performance.
Cutover, validation, and automation rebuild handoff
We freeze ELAINE writes during cutover, run a final delta migration of any records modified during the migration window, and enable Nutshell as the system of record. We deliver the Mail Sequence inventory document and the Integration inventory document to the customer's admin team. We support a one-week hypercare window for reconciliation issues. We do not rebuild ELAINE Mail Sequences as Nutshell Workflows inside the migration scope; that is documented separately for the customer's admin or a Nutshell partner.
