Overview
Moving from SalesNexus to Mailchimp is a down-select migration: Mailchimp is an email and SMS marketing platform, not a full CRM, so CRM-native objects like Pipelines, Pipeline Stages, Tasks, and Nexi AI features do not transfer. We migrate the marketing layer — Contacts to Mailchimp Members, Email Templates to Mailchimp Templates, Marketing Forms to Mailchimp Forms, and custom fields to merge fields — preserving the data that matters for continued outreach. We flag any overage against Mailchimp's contact-tier limits before import, handle the merge field type conversion from SalesNexus field types to Mailchimp's 255-character TEXT limit, and deliver a written inventory of SalesNexus CRM objects (Pipelines, Stages, Tasks, drip automations, Nexi AI) that require manual rebuild or are not supported in Mailchimp at all.
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 SalesNexus object lands in Mailchimp, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
SalesNexus
Contact
Mailchimp
Member
1:1SalesNexus Contact records map to Mailchimp Members within a designated Audience. The contact email address is the primary key for deduplication. First name, last name, phone (if present), and any standard fields migrate directly. Custom fields migrate as merge fields (see custom field notes). Contact status (active/inactive) maps to Member status in Mailchimp. SalesNexus does not expose a bulk export endpoint for contacts — we use paginated REST API calls with exponential backoff and chunking to extract the full contact list without triggering rate-limit errors on Starter-plan accounts with 500 API call limits.
SalesNexus
Company
Mailchimp
Tag or Merge Field
many:1SalesNexus Company records have no direct Mailchimp equivalent. Mailchimp is audience-centric, not account-centric. We offer two strategies during scoping: (1) Map each Company to a Tag on the related Member records, preserving the company name as a label for segmentation. (2) Create a MERGE0-style text merge field on the Mailchimp Audience and populate it with the Company name. Strategy 1 is preferred for segmentation use cases; Strategy 2 preserves the data for reporting but does not support multi-company filtering in Mailchimp's native UI.
SalesNexus
Email Template
Mailchimp
Template
1:1SalesNexus Email Templates with merge fields and HTML content export as template bodies and subject lines. We convert SalesNexus merge field syntax (typically {{contact.field_name}} or similar) to Mailchimp merge tag format (*|FNAME|*, *|LNAME|*, *|EMAIL|*, *|PHONE|*, and custom *|MERGEn|* or *|FIELDNAME|* tags). HTML email templates migrate as code, and we validate the converted template in a test send before committing to the destination Audience. Plain-text versions are generated from HTML for Mailchimp's multipart format support.
SalesNexus
Marketing Form
Mailchimp
Form
1:1SalesNexus Marketing Forms with field configurations and webhook/post URLs migrate as Mailchimp signup forms. Form field labels and input types map to Mailchimp field types (text, email, number, phone, date, dropdown, radio, checkbox). The SalesNexus form submission history migrates as a list of existing Members with the form's tags applied so that historical form submissions are represented in Mailchimp audience tags. Iframe embed codes from SalesNexus are platform-specific and must be replaced with Mailchimp's form embed code post-migration.
SalesNexus
Custom Field (Contact)
Mailchimp
Merge Field
1:1SalesNexus custom fields on Contacts identified by field IDs export via get-all-fields, and each field label, type, and value set maps to a Mailchimp merge field. Mailchimp imposes a 255-character limit on TEXT merge fields, so long-text custom fields from SalesNexus are truncated at 255 characters with a flag in the migration report. Date fields map to Mailchimp DATE merge fields. Number fields map to NUMBER merge fields. Dropdown-style fields map to RADIO or dropdown merge fields with the value set preserved. We create the merge fields on the Mailchimp Audience before importing Members so that field values are populated during the member insert rather than requiring a separate field update pass.
SalesNexus
Pipeline
Mailchimp
Not supported
1:1SalesNexus Pipelines (up to 100 on Enterprise) have no Mailchimp equivalent. Mailchimp does not support deal stages, opportunity records, or pipeline tracking. We do not migrate Pipeline records. We deliver a written pipeline inventory documenting pipeline names, stage counts, stage names, and probability defaults so that the customer's admin can decide whether to recreate any pipeline logic in a separate CRM tool if needed.
SalesNexus
Pipeline Stage
Mailchimp
Not supported
1:1Pipeline Stages do not migrate. Mailchimp has no stage model. Any historical deal data in SalesNexus pipeline stages is documented as a written record for the customer's admin to evaluate for manual entry into a future CRM tool.
SalesNexus
Task
Mailchimp
Not supported
1:1SalesNexus Tasks (open and completed) have no Mailchimp equivalent. Mailchimp does not have a task or activity management layer. We export the task list as a CSV inventory and deliver it to the customer's admin for manual review or import into a separate task management tool if needed.
SalesNexus
Drip Automation
Mailchimp
Not supported
1:1SalesNexus drip automation sequences are stored server-side and are not accessible via the public API. We can export the list of active contacts enrolled in each sequence and the sequence names, and apply those sequence names as Mailchimp Tags on the corresponding Member records so that enrollment history is preserved as a segmentation label. The trigger logic, delay rules, and conditional branches must be manually rebuilt in Mailchimp Customer Journeys. We provide a sequence audit report listing all active automations and their enrollments for the admin's rebuild reference.
SalesNexus
Nexi AI Suggestions
Mailchimp
Not supported
1:1Nexi AI features (AI Email Assistant, AI Meeting Notes, Smart Recommendations) are platform-native and do not expose exported data. Any Nexi-generated content stored as contact notes is exported as plain-text notes, but the AI model state and inference outputs cannot be migrated. We document which Nexi features are active in the source account and deliver a feature inventory so customers understand what will be lost before committing to the migration.
SalesNexus
Email Archival
Mailchimp
Activity Tags
1:1SalesNexus email archival (unlimited on all plans) exports email subject, body, date, direction (sent/received), and related contact. In Mailchimp, we represent this as Member tags (e.g., 'Emails Opened', 'Campaign Sent') and a contact note containing the last five archived email subjects and dates. Full email body archival does not have a native Mailchimp storage equivalent, so we provide a CSV export of all archived emails linked by contact email for the customer's records.

SalesNexus gotchas
Dual-platform account confusion blocks clean exports
Contact tier limits are enforced at migration time
Drip automation sequences are not exportable via API
API rate limits restrict export throughput on Free and Starter plans

Pair-specific challenges
Migration approach
Account and platform identification
We confirm whether the customer uses the SalesNexus 2026 platform (app.salesnex.us) or the legacy platform (salesnexus.com) and identify which system holds the active data. For customers with data in both, we agree on scope with the customer before export begins. We also confirm the Mailchimp destination account, plan tier, and existing Audience configuration to determine contact-tier headroom for the import.
Asset inventory and field schema export
We export the full SalesNexus field schema via get-all-fields to capture every custom field label, type, and ID. We inventory all email templates (with HTML content), marketing forms (with field configurations), and drip automation sequences (with enrollment counts per sequence). We count total contacts, total companies, and total custom field values to validate against Mailchimp plan limits before committing to migration. This inventory produces the written handoff documents for items that do not migrate.
Merge field mapping and Mailchimp schema setup
We map each SalesNexus custom field to a Mailchimp merge field of the appropriate type (TEXT, NUMBER, DATE, RADIO, dropdown). We truncate any values exceeding 255 characters and flag the affected records. We create the merge fields on the Mailchimp Audience via the Mailchimp API before member import so that the field schema is ready at insert time. We map SalesNexus merge field syntax in templates to Mailchimp merge tag syntax.
Contact and company export with rate-limit handling
We export SalesNexus contacts via paginated REST API calls using exponential backoff and chunking to stay within plan rate limits. Company names are extracted for tagging strategy. We validate the total contact count against the Mailchimp plan limit and flag any overage for plan adjustment before proceeding. Active drip automation enrollments are exported as a tag list for application to Mailchimp Members.
Template and form migration
Email templates with HTML content and merge field syntax are converted and uploaded to Mailchimp as Templates. We validate each template with a test send to a designated test audience. Marketing forms are configured in Mailchimp's new form editor with field labels and types matching the SalesNexus schema. Form submission history is applied as tags on existing Members.
Member import and tag application
Contacts are imported into Mailchimp as Members using the Mailchimp Members API with upsert behavior (existing Members are updated, new Members are created). Company associations are applied as Tags (strategy 1) or as a text merge field (strategy 2) based on the customer's scoping choice. Drip automation enrollment tags are applied in a batch operation after member import completes. Each phase emits a row-count reconciliation report.
Cutover and handoff documentation
We freeze SalesNexus writes during cutover, run a final delta migration of any records modified during the migration window, then deliver the full handoff package. The package includes: the Member import reconciliation report, the drip automation inventory (for Customer Journey rebuild), the pipeline and task inventory (for future CRM evaluation), the Nexi AI feature inventory (for feature gap analysis), the truncated custom field report (for manual data review), and the form embedding update checklist. We do not rebuild drip automations as Mailchimp Customer Journeys within migration scope; that is a separate engagement or an internal admin task.
