Overview
Moving from Promio to Nutshell is a migration from a campaign-centric local marketing automation platform to a structured B2B CRM with its own native REST API and unlimited-contact pricing model. Promio holds data around Leads, Campaigns, Customers, and lifecycle segments, but has no public API — extraction relies entirely on negotiated CSV exports coordinated through Promio's support or account management team. We map Promio Leads and Customers to Nutshell People (linked to Companies where a business entity exists), preserve lifecycle segment labels as custom Person fields, and migrate campaign performance history as custom fields on Company records. Promio's call recordings, landing pages, and ad account credentials do not transfer; we inventory these as rebuild requirements for the customer's post-migration work. Nutshell's core data model (People, Companies, Deals, Activities) is well-supported by its REST API, allowing us to use chunked API writes with validation rather than CSV-only import. We do not migrate Promio Workflows, automated campaigns, or landing page configurations; these are documented for the customer to rebuild in Nutshell Marketing and Engagement or their own web stack.

Object mapping
Each row shows how a Promio 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.
Promio
Lead
Nutshell
Person (People)
1:1Promio Leads map to Nutshell People records. We extract lead records from the Promio CSV export including source attribution, campaign association, call-tracking metadata (phone number, call duration), and any custom property columns discovered during export inspection. The Nutshell Person record receives standard fields (name, email, phone, address) and any discovered custom properties as Nutshell custom fields. Promio leads without an associated business entity map directly to Person; leads with a business name receive the business as a Person note or link to a newly created Nutshell Company if a match is found.
Promio
Customer
Nutshell
Person + Company (lookup)
1:1Promio Customers map to Nutshell People linked to Nutshell Companies where a business entity is identified. The five lifecycle segment labels — New, Active, At-Risk, Lapsed, Lost — migrate as custom fields on the Person record. We preserve the exact Promio label names (New, Active, At-Risk, Lapsed, Lost) as a custom picklist field so the customer can maintain their existing segmentation logic in Nutshell reporting. Customer-level advertising attribution data (cost per acquisition per campaign) migrates as a custom text field on the linked Company for revenue reporting continuity.
Promio
Campaign
Nutshell
Company (custom fields)
lossyPromio Campaigns bundle advertising channels with automated drip sequences and budget data. Since Nutshell does not have a native Campaign object at the CRM layer (Campaign is a Nutshell Marketing feature), we map campaign names to Nutshell Company records using a naming convention (e.g., prefix 'PromioCampaign-' on the Company name) and store campaign budget allocations, performance metrics (impressions, clicks, spend, conversions), and channel data as custom fields on that Company. The customer can report on these via Nutshell's custom reporting tools. Promio campaign sequences do not migrate as automations.
Promio
Advertising Account
Nutshell
External (out-of-scope)
1:1Google Ads and Bing Ads account credentials are linked to Promio through its managed-service layer and do not transfer during CRM migration. We document the current campaign structure, budget allocations, performance history, and keyword lists from the Promio export as a structured CSV and written summary. The customer independently re-grants access to their Google Ads and Bing Ads accounts outside of Nutshell and uses the documented campaign structure to rebuild ad campaigns directly in those platforms. This is outside CRM migration scope but we include the documentation as a migration artifact.
Promio
Call Recording
Nutshell
External (non-migratable)
1:1Promio's call-tracking feature stores audio recordings on Promio's own infrastructure and these files are not included in standard CSV exports. We flag this as a hard stop in the migration scope document: the customer must download all required call recordings directly from Promio's interface before the cutover date. We provide a checklist of call recording URLs from the Promio export metadata so the customer knows exactly which recordings to pull. We cannot migrate these post-cutover. This item appears in our pre-flight checklist and is a gating requirement before we begin the production data load.
Promio
Landing Page
Nutshell
External (rebuild required)
1:1Custom landing pages created in Promio are served from promio.com subdomains and are not exportable as portable HTML assets or redirect-configurable on migration. We inventory all active landing pages during scoping — recording the page URL, form field structure, associated Promio campaign, and estimated monthly submission volume — and deliver this as a page-by-page rebuild requirements document. The customer rebuilds landing pages in Nutshell Marketing, their own website, or a third-party landing page tool post-migration.
Promio
Reputation / Review Data
Nutshell
Person (custom fields)
1:1Promio aggregates review monitoring data (ratings, review site links, reputation scores) from third-party aggregators into its dashboard. We extract the aggregated scores and review site URLs from the CSV export as custom fields on the corresponding Nutshell Person record. Review ratings migrate as a custom number field; review URLs migrate as a custom URL field per review site. The customer uses these for reference and rebuilds any active review-response workflows in Nutshell manually.
Promio
Custom Properties (Leads and Customers)
Nutshell
Person / Company (custom fields)
lossyPromio allows custom fields on Leads and Customers tied to its campaign attribution and lifecycle system. These are discovered during the extraction phase by inspecting the exported CSV column headers, as Promio does not publish schema documentation publicly. We create equivalent custom fields in Nutshell for each discovered Promio custom property, matching the data type (text, number, date, picklist) to the appropriate Nutshell custom field type. Any custom fields added in Promio after the export date will not be captured unless a second export is run; we schedule the final export as close to the cutover date as possible to minimize this gap.

No public API forces manual or negotiated export
Call recordings live on Promio infrastructure
Ad account re-onboarding required after migration
Landing pages are Promio-hosted and non-portable
Custom properties lack standard field documentation

Migration approach
Discovery and export coordination
We audit the Promio account to identify all record types present (Leads, Customers, Campaigns, custom properties, reputation data), estimate record volumes per type, and inventory the landing pages and call recordings in scope. Simultaneously, we submit a formal data export request to Promio on the customer's behalf, specifying the exact record types and field columns needed. Nutshell sandbox provisioning happens in parallel. We deliver a written discovery summary and confirm the final export date before beginning transformation work.
Promio export receipt and CSV validation
When the Promio CSV export arrives, we validate completeness against the discovery inventory: record counts per type, column headers against expected fields, and presence of all custom property columns. We flag any missing fields or truncated records immediately and escalate to Promio support if the export is incomplete. This step is the critical path because Promio's manual export process can introduce delays if files are incomplete or missing columns that were added after the initial request.
Schema design and custom field creation in Nutshell
We design the destination schema in the Nutshell sandbox. This includes creating custom fields on Person for the five Promio lifecycle segments (New, Active, At-Risk, Lapsed, Lost) and any additional custom properties discovered in the CSV headers. We create custom fields on Company for campaign performance metrics (budget, spend, impressions, conversions). We design any required Nutshell Companies for Promio campaign records using a naming convention that distinguishes campaign records from business Account records. Field types are matched precisely (text, number, date, picklist) to Nutshell's supported custom field types.
Sandbox migration and reconciliation
We run a full migration into the Nutshell sandbox using the exported Promio data. The customer's team reconciles record counts (People in, Companies in), spot-checks twenty to thirty records against the Promio source data, and verifies that lifecycle segment labels, campaign names, and custom property values appear correctly in Nutshell. Any mapping corrections are made before production migration begins. The customer signs off the sandbox migration before we proceed to production.
Production migration in dependency order
We run production migration in record-dependency order: Nutshell Companies first (for campaign records and any matched business entities), then Nutshell People (Leads and Customers with lifecycle custom fields and activity history). Each phase emits a row-count reconciliation report before the next phase begins. Nutshell's REST API is used for all inserts with batch chunking and validation error handling. Activities (calls, emails, meetings, tasks) migrate via the Nutshell Activities API where supported or as Note records linked to the Person for timeline continuity.
Cutover and post-migration handoff
We freeze writes to Promio during cutover, run a final delta migration of any records modified during the migration window, then confirm Nutshell as the system of record. We deliver the Promio landing page rebuild requirements document, the Promio ad account structure and budget documentation, the Promio automation inventory (for manual rebuild in Nutshell Marketing and Engagement), and the call recording pre-flight checklist confirmation. We support a five-business-day hypercare window for reconciliation issues. We do not rebuild Promio Workflows, automated campaigns, or landing pages as part of the migration scope.
