Overview

What this migration involves

Moving from Spotler Mail+ to Microsoft Microsoft Dynamics 365 Sales is a contact-centric migration with structural translation required because the two platforms use different entity models. Spotler stores contact-level attributes as Tags, Scores, and Custom Fields against a single Contact record; Microsoft Dynamics 365 Sales separates unqualified prospects into Leads and qualified buyers into Contacts attached to Accounts. We resolve that mapping during scoping, migrate Tags as multi-select picklists and Scores as number fields on the Contact, and preserve the Spotler Contact ID in a custom field for cross-system audit. Mailings from Spotler become Campaign Activity records linked to the target Lead or Contact. Spotler automations and the drag-and-drop template editor do not migrate; we deliver a written inventory of automation triggers and content assets for your admin to reassemble in Dynamics Workflow or Power Automate.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Spotler Mail+

What's pushing teams away

  • Automation features are cited as a recurring frustration, with users noting the workflow editor is functional but limited compared to dedicated marketing automation platforms like ActiveCampaign or HubSpot.
  • Template quality and flexibility issues appear in reviews, with some users reporting that the drag-and-drop editor produces inconsistent results across email clients.
  • Deliverability configuration requires manual attention, and users migrating away commonly cite inbox placement struggles and the need for third-party deliverability tooling.
  • Performance issues including slow dashboard load times and delayed campaign statistics reporting are mentioned in multiple negative reviews on G2.
  • The platform's single-brand focus on Mail+ versus the multi-brand MailPro tier means teams managing multiple brands outgrow the product and migrate to enterprise alternatives.

Choosing

Microsoft Dynamics 365 Sales  logo

Microsoft Dynamics 365 Sales

What's pulling them in

  • Deep Microsoft 365, Teams, and Outlook integration makes Microsoft Dynamics 365 Sales a natural fit for Microsoft-first organizations already invested in that ecosystem
  • Sales Enterprise and Premium tiers offer unlimited custom tables and advanced AI-driven forecasting and predictive analytics not available in lower tiers
  • Professional tier pricing at $65 per user per month offers a lower entry cost than Salesforce for SMB teams with straightforward CRM needs
  • Flexible customization options allow businesses to build bespoke apps, tailor forms and views, and integrate with other Dynamics 365 modules
  • Microsoft Copilot AI tools are embedded directly into the sales workflow on Enterprise and Premium, automating routine tasks and providing deal intelligence

Object mapping

How Spotler Mail+ objects map to Microsoft Dynamics 365 Sales

Each row shows how a Spotler Mail+ object lands in Microsoft Dynamics 365 Sales , including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Spotler Mail+

Contact

maps to

Microsoft Dynamics 365 Sales

Lead or Contact (split required)

1:many
Fully supported

Spotler Contacts with no purchase history or marketing qualification score map to Microsoft Dynamics 365 Sales Lead. Spotler Contacts with an assigned sales rep, active deal association, or customer status map to Dynamics Contact attached to an Account. We compute the split during scoping using Spotler tag values and score thresholds defined by the customer, and store the original Spotler contact ID in a custom field for cross-system audit and reconciliation.

Spotler Mail+

Tag

maps to

Microsoft Dynamics 365 Sales

Multi-select Option Set on Contact

1:1
Fully supported

Spotler Tags are contact-level label attributes accessible via the REST API. We migrate them as Dynamics multi-select option set values on the Contact object, preserving the tag name string and mapping multi-value tags to the option set delimited format. Option set values are defined in the Dynamics solution before Contact import begins.

Spotler Mail+

Score

maps to

Microsoft Dynamics 365 Sales

Number Field on Contact

1:1
Fully supported

Spotler lead scoring values stored as numeric contact properties map directly to Dynamics number fields on Contact. We create a custom number field with appropriate decimal precision matching the source Spotler score range, and migrate the score value with the original Spotler timestamp as a secondary field for longitudinal reporting.

Spotler Mail+

Custom Fields

maps to

Microsoft Dynamics 365 Sales

Custom Fields on Contact and Account

lossy
Mapping required

Spotler supports text, numeric, currency, list, date, and permission field types. We map each Spotler field type to its Dynamics equivalent: text to Single Line of Text, numeric to Whole Number or Decimal depending on precision, currency to Currency type with the correct ISO precision, list to Option Set, date to Date field, and permission to Two Options boolean. Import column names must match Spotler database field names exactly; we validate the field registry before migration.

Spotler Mail+

Mailing

maps to

Microsoft Dynamics 365 Sales

Campaign Activity

1:1
Fully supported

Spotler Mailings are API-accessible send records with subject, sender, content, and send date. We migrate mailing metadata as Campaign records in Dynamics with the send date, open rate, click rate, and delivery status stored on custom Campaign fields. Opens and clicks migrate as CampaignActivity records if they fall within the 24-month Spotler retention window. We scope the mailing history migration to the active window and flag any pre-window records as unavailable per Spotler's anonymization policy.

Spotler Mail+

Audience Segmentation

maps to

Microsoft Dynamics 365 Sales

Static Marketing List or Campaign

1:1
Fully supported

Spotler segmentation rules themselves are not exportable as executable logic. We extract the resulting contact sets as static lists or marketing lists in Microsoft Dynamics 365 Sales , preserving the list name and member contacts. The segmentation rule logic is documented for the customer's admin to recreate in Dynamics Campaign or Customer Insights segmentation builder.

Spotler Mail+

Form Request

maps to

Microsoft Dynamics 365 Sales

Custom Fields on Contact or Note

lossy
Fully supported

Spotler form submissions export as flat records rather than relational question-response data. We denormalize each form submission into Contact custom fields using a field naming convention that encodes the form name and question label, or into Note records attached to the Contact for longer-form responses. Survey closure rules do not export and are noted for manual rebuild in Dynamics Forms or a Power Apps portal.

Spotler Mail+

Template

maps to

Microsoft Dynamics 365 Sales

HTML/CSS Content Asset

1:1
Fully supported

Spotler drag-and-drop email templates do not export in a portable format. We extract the rendered HTML content, inline CSS, and embedded image URLs as a content package for manual reassembly in Dynamics Email Template editor or SharePoint. The template layout structure is documented with a screenshot reference so the customer's marketing team can recreate the visual design.

Spotler Mail+

User

maps to

Microsoft Dynamics 365 Sales

User

1:1
Fully supported

Spotler user accounts with roles and access levels map to Dynamics User records. We extract user name, email address, and role assignments by email match against the destination Dynamics org. Any Spotler user without a matching Dynamics User is held in a reconciliation queue for the customer's admin to provision before Contact import begins.

Pair-specific challenges

  • Spotler purges mailing interaction data after 24 months

    Spotler Mail+ anonymizes all opens, clicks, and delivery statistics after 24 months. If a customer is migrating historical campaign performance data, we must scope the reporting migration to the most recent 24-month window and notify them upfront that pre-purge historicals are unavailable from Spotler regardless of export method. Any Spotler API query or export for interaction records older than 24 months returns empty or scrubbed values.

  • Spotler import files require exact column-name matching

    Spotler Mail+ accepts only XLS, XLSX, CSV, and TXT formats for imports. Column headers must map exactly to database field names, filters in the source file are ignored during import, and only the first tab is processed. We validate the file structure against Spotler's field registry before migration. Multi-tab files must be pre-merged and validated. This is a common failure point for customers who have added sheets or modified headers over time without updating the import mapping.

  • Spotler connector for Dynamics handles only Contacts and Accounts

    The Spotler-built native connector for Microsoft Dynamics 365 exchanges only Contacts, Leads, and Accounts. It does not sync Mailings, Audiences, Tags, Scores, Form Requests, or Templates. Any Spotler data outside the connector scope requires migration by other means. We scope all non-contact objects explicitly and confirm that no connector assumption applies to the full data set.

  • Spotler automations do not migrate as executable rules

    Spotler campaign logic, triggers, and drip sequences are platform-native automation objects that cannot be exported as portable rules. We document the automation structure including triggers, conditions, and actions for the customer's admin to rebuild in Microsoft Dynamics 365 Sales Workflow, Power Automate, or Dynamics 365 Customer Insights Journeys. The rebuild is outside standard migration scope.

  • Dynamics API service protection limits require batch processing

    Microsoft Dynamics 365 Sales enforces service protection API limits (approximately 6,000 requests per five minutes per user) and license-based request allocations. Spotler also lacks a bulk export endpoint, requiring paginated looping for large contact databases. We implement batch chunking, exponential backoff on 429 responses, and cursor-based pagination for Spotler extraction, and use Dynamics ExecuteMultipleRequest for bulk inserts to stay within service protection limits.

Migration approach

Six steps for a successful Spotler Mail+ to Microsoft Dynamics 365 Sales data migration

  1. Discovery and data audit

    We audit the source Spotler Mail+ portal for contact volume, custom field definitions and types, tag vocabulary, score ranges, audience segmentation sets, mailing history within the active 24-month window, and form submission records. We also review the Spotler tier (Mail+ or MailPro) and any multi-brand configuration that affects the data architecture. We pair this with a Microsoft Dynamics 365 Sales edition review (Sales Professional at $65 per user per month or Sales Enterprise at $105 per user per month) and confirm existing Microsoft licensing. The discovery output is a written migration scope document listing every object class, estimated row counts, and any pre-migration data quality flags.

  2. Schema design and field-type mapping

    We design the destination Dynamics schema before any data moves. This includes creating custom fields on Contact and Account that map Spotler field types to typed Dynamics fields (text to Single Line of Text, numeric to Whole Number or Decimal, currency to Currency type, list to Option Set, date to Date, permission to Two Options). We create a multi-select Option Set for Spotler Tags and a number field for Scores. We configure Dynamics Business Units if the customer uses multi-brand segmentation. Schema is deployed via the Dynamics Web API into a Sandbox org for validation before production.

  3. Sandbox migration and reconciliation

    We run a full migration into a Dynamics Sandbox using representative data volume. The customer reconciles record counts, spot-checks field values against the Spotler source, and validates parent-child relationships (Account to Contact, Lead to Contact) before we proceed to production. We fix any field-type mismatches, Option Set value gaps, or required-field validation rules in the Sandbox. No data moves to production until the Sandbox sign-off.

  4. Owner reconciliation and User provisioning

    We extract every distinct Spotler user referenced on Contact records and match by email against the Dynamics User table. Any Spotler user without a matching Dynamics User is queued for the customer's admin to provision. Migration of Contacts cannot proceed past this step because OwnerId references on Contacts require a valid Dynamics User. We also extract the Spotler contact created-by and modified-by timestamps for audit preservation.

  5. Production migration in dependency order

    We run production migration in record-dependency order: Accounts (from Spotler organization or company fields), Leads and Contacts (with AccountId resolved and the Tag/Score split applied), Option Set values for Tags, number fields for Scores, Mailings as Campaign records with activity metrics, Audience segments as static marketing lists, Form submissions as Contact custom fields or Note records, and Template content as HTML/CSS assets. Each phase emits a row-count reconciliation report before the next phase begins. We implement pagination with checkpointing on the Spotler side and batch processing with retry logic on the Dynamics Bulk API side.

  6. Cutover, validation, and automation handoff

    We freeze Spotler Mail+ writes during cutover, run a final delta migration for any records modified during the migration window, then enable Microsoft Dynamics 365 Sales as the system of record. We deliver an automation inventory document listing every Spotler campaign automation trigger and recommended Dynamics Workflow or Power Automate equivalent, plus a template asset package for the marketing team to reassemble in the Dynamics Email Template editor. We support a one-week hypercare window for reconciliation issues raised by the customer's team.
