Overview
e-shot functions primarily as an email marketing platform with contact management and campaign tracking. HubSpot CRM offers a richer object model — contacts, companies, deals, tickets, calls, emails, meetings, and custom objects — with native lifecycle stages, deal pipelines, and an association graph between records. The migration carries e-shot contacts and their properties into HubSpot Contacts, campaign membership into HubSpot custom properties or campaign associations, and engagement history (opens, clicks, sends) into HubSpot's contact activity timeline or custom properties. We do not migrate e-shot workflows or automation sequences — those must be rebuilt in HubSpot's workflow engine. Custom properties created in e-shot map to HubSpot custom contact or company properties, which your HubSpot admin creates before data lands. The migration runs via HubSpot's API and Bulk API endpoints, with a scoped read-access credential on e-shot so your team continues working throughout the cutover window. During the cutover window, FlitStack AI reads e-shot data through a scoped read‑only credential, ensuring your marketing team can continue launching campaigns without interruption. The migration engine writes records to HubSpot via the CRM API and Bulk API, handling batched inserts, property validation, and duplicate detection. After the primary load, a delta‑pickup phase captures any new or updated contacts that arrived in e-shot during the cutover, ensuring the final HubSpot dataset matches the source at go‑live.
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 e-shot object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
e-shot
Contact
HubSpot
Contact
1:1HubSpot's primary CRM object. All e-shot contact properties migrate as HubSpot contact properties. First name, last name, email, phone, job title, and address fields map directly. Custom e-shot properties become HubSpot custom contact properties after your admin creates the schema in HubSpot.
e-shot
Company (e-shot contact property)
HubSpot
Company
1:1e-shot stores company as a text property per contact. We extract unique company names, create HubSpot Company records, and link each contact to their primary Company via the HubSpot association. Secondary company associations (N:1 in e-shot) surface as additional Company associations in HubSpot.
e-shot
Campaign Membership
HubSpot
Campaign + Campaign Member
1:1e-shot campaign data per contact migrates to HubSpot Campaigns with campaign membership records. Each e-shot campaign becomes a HubSpot Campaign object; contact participation maps as Campaign Members with activity type and date preserved. Campaign names and IDs stored in HubSpot for reconciliation.
e-shot
Email Engagement (open, click, send, bounce)
HubSpot
Contact Activity Timeline + Custom Properties
1:1e-shot engagement events (opens, clicks, unsubscribes, bounces) are too granular for HubSpot's native activity model. We summarize engagement history as custom properties on the Contact (e.g., last_email_open_date, total_email_opens, last_click_date) and attach a structured engagement log as a CSV file uploaded to the contact's file attachments for audit reference.
e-shot
Contact Property (custom)
HubSpot
Contact Property (custom)
1:1Every e-shot custom contact property requires a corresponding HubSpot custom property. Your admin creates the HubSpot property first (Settings > Properties > Contact properties) with the correct type (string, number, date, enumeration). We surface the full property list in the migration plan so nothing is missed before data lands.
e-shot
Tag / Segment
HubSpot
HubSpot List or Contact Property
1:1e-shot contact tags or segment membership migrate to HubSpot as either static lists (one per tag) or as a multi-select custom contact property (tags_as_string__c). Multi-select is preferred for compatibility with HubSpot's list and workflow engine. Your admin chooses the strategy before migration runs.
e-shot
Owner / User
HubSpot
HubSpot User
1:1e-shot user records map to HubSpot users by email address match. Unmatched users are flagged before migration — your team either creates HubSpot user accounts first or assigns records to a fallback HubSpot owner. No record lands without a valid HubSpot owner assignment.
e-shot
Form Submission
HubSpot
Contact Property + Note
1:1e-shot form submission data per contact migrates as HubSpot contact properties (submission date, form name, utm source) and a Note attached to the contact record. Form field values that differ from standard contact properties become custom contact properties created in HubSpot before migration.
e-shot
Automated Series / Workflow
HubSpot
Not Migrated
1:1e-shot automated series and workflow definitions do not have a HubSpot equivalent at the data layer. They must be rebuilt in HubSpot's workflow engine post-migration. We export your e-shot series definitions as a structured JSON reference document for your HubSpot admin to use during the rebuild phase.
e-shot
Landing Page
HubSpot
HubSpot Landing Page
1:1e-shot landing pages are HTML assets that cannot be imported into HubSpot's landing page module. The content, form fields, and lead-gen URL structure are documented in the migration plan. Your team rebuilds landing pages in HubSpot's design manager using the content as a reference.
e-shot
Attachment / File
HubSpot
HubSpot File Manager
1:1Files attached to e-shot contact records download and re-upload to HubSpot's file manager, linked to the contact record via the Files tool. File size limits follow HubSpot's file upload constraints (up to 256MB per file in most plans). Inline images in email templates are re-hosted and URL-updated.
e-shot
SMS Campaign Data
HubSpot
Contact Property + HubSpot SMS Tool (post-migration)
1:1e-shot SMS campaign membership migrates to HubSpot as custom contact properties tracking SMS opt-in status, last SMS send date, and campaign name. Full SMS campaign history and message content requires HubSpot's paid SMS add-on, which your team configures post-migration. These properties enable basic SMS attribution in HubSpot reports and list segmentation. Full message content remains in e-shot until your team configures HubSpot's SMS add-on.

Migration approach
Audit e-shot contact schema and create HubSpot custom properties
FlitStack AI extracts the full e-shot contact property inventory including all custom fields, pick-list values, and UTM parameters. We compare this against HubSpot's existing contact properties and generate a property creation checklist for your HubSpot admin. Every custom e-shot field gets a corresponding HubSpot custom property (with the correct type: string, number, date, enumeration, or boolean). The schema must be complete before the first migration batch runs — HubSpot's API rejects records with unrecognized property names.
Extract e-shot companies into HubSpot Company records
e-shot stores company as a text property per contact, not as a separate object. We extract all unique company names, create HubSpot Company records, and map each contact's company property to the HubSpot Company lookup. Parent-company relationships, if present in e-shot as custom fields, map to HubSpot's Parent Company field. Secondary company associations per contact are preserved as custom multi-select properties. Company records are migrated before contacts so the Contact-Company lookups resolve correctly.
Resolve e-shot users to HubSpot owners by email
e-shot user accounts map to HubSpot owners by email address. We run an owner resolution pass against your HubSpot user list before migration. Unmatched users are flagged in the migration plan — your team creates HubSpot user accounts or assigns records to a fallback owner before the migration commits. No contact lands in HubSpot without a valid OwnerId. This step also captures the e-shot user ID and stores it on the contact record for post-migration audit.
Run a sample migration with field-level diff on 200–500 records
A representative slice of e-shot contacts migrates into your HubSpot sandbox or staging portal first — typically 200–500 records spanning different contact types, tag categories, and engagement levels. We generate a field-level diff showing each source field, the HubSpot destination property, the mapped value, and any validation warnings (unmatched pick-list values, blank required fields, owner resolution failures). You review the diff before the full migration commits. This is the point to catch any custom property naming mismatches or lifecycle stage mapping gaps.
Execute full migration with delta-pickup window for in-flight changes
The full migration batch runs against your HubSpot portal via the HubSpot CRM API and Bulk API. FlitStack AI sequences the migration: Companies first, then Contacts, then Campaign Membership and engagement summaries. During the cutover window your team continues working in e-shot — scoped read access is used, not write access. A delta-pickup window (typically 24–48 hours) captures any new contacts or updated records created in e-shot during the cutover. An audit log records every operation, and one-click rollback is available if the reconciliation check fails.
