Overview
Moving from SalezShark CRM to Mailchimp is a category shift: SalezShark is a full CRM with Leads, Accounts, Opportunities, and Workflow Automations; Mailchimp is an audience-based email marketing platform with no native Opportunity, Pipeline, or Workflow equivalent. We extract all Contacts and Accounts from SalezShark via CSV exports (the platform has no public API), map them to Mailchimp audience members with tag-based segmentation, and re-associate any Account-level data as merge fields or tags on the contact record. Custom fields that exceed Mailchimp's 30-field audience limit (or 80-field limit on Premium) are surfaced as candidate fields to create post-import. We do not migrate Opportunities, Pipelines, Workflow Automations, or Sales Engagement Sequences because Mailchimp does not have these objects; we deliver a written inventory of every automation requiring rebuild so the customer's marketing team can replicate them in Mailchimp's automation builder post-migration.
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.

Object mapping
Each row shows how a SalezShark 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.
SalezShark
Contact
Mailchimp
Audience Member
1:1SalezShark Contacts map to Mailchimp Audience members. The primary key is email address; we use Mailchimp's upsert behavior (create if new, update if existing by email) during import. Standard fields (first name, last name, email, phone, address) map directly to Mailchimp's FNAME, LNAME, EMAIL, PHONE, and address merge fields. Status in SalezShark (active/inactive) maps to Mailchimp's subscribed, unsubscribed, or cleaned status — we use the contact's last activity date and email engagement history to set initial status at import time to avoid sending to bounced or disengaged addresses immediately after migration.
SalezShark
Account
Mailchimp
Merge Fields and Tags (on Audience Member)
lossySalezShark Account records do not have a direct Mailchimp object equivalent because Mailchimp has no Company or Account concept. We pull Account-level fields (company name, industry, website, annual revenue, employee count) and map them to Mailchimp merge fields (COMPANY, INDUSTRY, WEBSITE) or as tags on the associated Contact record (e.g., tag: Industry:Technology). The customer chooses the strategy during scoping based on how they plan to use segmentation in Mailchimp.
SalezShark
Lead
Mailchimp
Audience Member (with tag)
1:1SalezShark Leads map to Mailchimp Audience members tagged with 'Source: Lead' to distinguish them from converted Contacts. We preserve the Lead's conversion score and status in a merge field (LEAD_STATUS, LEAD_SCORE) if those fields exist in SalezShark and the customer requests them. Unconverted Leads that have not yet moved through a sales process are imported as subscribed members so they can enter Mailchimp's automation Journeys immediately.
SalezShark
Custom Fields
Mailchimp
Audience Merge Fields
lossySalezShark Custom Fields (available on Basic tier and above) map to Mailchimp audience merge fields. Mailchimp caps merge fields at 30 on Essentials and Premium plans, and 80 on Mailchimp Premium. We audit the custom field count during scoping; if the count exceeds Mailchimp's limit, we prioritize fields used in segmentation or automation conditions and flag the remainder as candidate fields to create post-import. Text merge fields in Mailchimp are limited to 255 characters, so long-text fields from SalezShark are truncated at import with a note to the customer.
SalezShark
Opportunity
Mailchimp
Not Migratable
lossySalezShark Opportunities and Pipelines have no Mailchimp equivalent. Mailchimp does not track deal stages, deal values, or pipeline velocity. We do not migrate Opportunity records. We deliver a written inventory of every open Opportunity with its stage, value, close date, and owner so the customer's sales team can re-enter these manually in their preferred sales tracking tool (or a new CRM if they adopt one alongside Mailchimp). Closed-won Opportunities may be imported as tags on the related Contact (e.g., 'Customer: Deal $X,000') for historical reference.
SalezShark
Task and Activities
Mailchimp
Not Migratable
lossySalezShark Tasks (calls, emails, meetings, tasks) do not map to any Mailchimp object. Mailchimp tracks email engagement activity (opens, clicks, bounces, unsubscribes) but not sales call logs, meeting notes, or internal task completion. We do not migrate task history. If the customer needs to preserve activity history for compliance or customer relationship context, we recommend a secondary CRM tool to maintain it separately from Mailchimp's audience data.
SalezShark
Workflow Automations
Mailchimp
Customer Journeys (written inventory only)
lossySalezShark Workflow Automations (Professional tier, $39/user/month) do not migrate to Mailchimp Customer Journeys because the trigger models differ significantly. SalezShark uses property-triggered workflow rules with CRM-object conditions; Mailchimp uses behavioral triggers (email opens, link clicks, signups, date-based) and Journey builder steps. We export every active SalezShark Workflow as a written specification — trigger conditions, filter logic, and downstream actions — and deliver it to the customer so their marketing team can rebuild equivalents in Mailchimp's automation builder. We do not rebuild automations as part of the migration scope.
SalezShark
Campaigns and Mass Email
Mailchimp
Audience Tags and Segments
lossySalezShark Campaign membership (Contacts and Leads enrolled in campaigns) migrates as Mailchimp tags on the Audience member record. Campaign names become tag prefixes (e.g., 'Campaign: Q4 Webinar'). Email content, templates, and creative assets do not migrate; we recommend re-creating key templates in Mailchimp using its drag-and-drop builder. Campaign-level reporting metrics (opens, clicks, bounces) do not transfer and are regenerated in Mailchimp post-migration.
SalezShark
Users
Mailchimp
Not Migratable
lossySalezShark User records (sales reps, admins) map to Mailchimp account users and audience permissions, not to contact records. We do not migrate User data as contact records. We map SalezShark Owner fields on Contacts and Leads to a SALES_REP merge field in Mailchimp so the contact record carries attribution to the original owner. The customer's Mailchimp account user setup is managed separately through Mailchimp's account settings post-migration.

SalezShark gotchas
No publicly documented API for automated extraction
Minimum 10-user billing regardless of actual headcount
Workflow Automations are not executable at migration time
Custom Field schema varies by tier and by org configuration
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported

Pair-specific challenges
Migration approach
Scoping and CSV export coordination
We audit the customer's SalezShark account to identify active objects (Contacts, Leads, Accounts, Custom Fields, Campaigns), tier level, and active user count. We coordinate with the customer's credentials to run CSV exports filtered by record type. We confirm the export schema matches the customer's custom field configuration before proceeding. We also capture any data quality issues (missing email addresses, duplicate records, bounced historical contacts) and produce a data cleansing checklist for the customer to address before import.
Mailchimp audience setup and field mapping
We create the Mailchimp audience and configure merge fields to match the SalezShark field schema within Mailchimp's limits. We prioritize fields used in segmentation and automation conditions. If the custom field count exceeds Mailchimp's limit, we create a field priority matrix and deliver it to the customer for approval before import. We set initial contact status (subscribed vs unsubscribed) based on the contact's last email engagement date in SalezShark to avoid triggering bounces on day one.
Data cleansing and duplicate resolution
We deduplicate contacts by email address before import — Mailchimp's upsert behavior will update existing members by email, but contacts with duplicate email addresses across Leads and Contacts need to be resolved manually or by rule (e.g., prefer Contact over Lead, prefer most recently updated record). We flag hard bounces and invalid email formats from SalezShark's historical data and recommend excluding them from the initial import to protect sender reputation. We deliver a duplicate and bounce report for customer review before the data load.
CSV import and tag strategy
We import Contacts, Leads, and Accounts into Mailchimp using the platform's native CSV import tool or Mailchimp API, following the audience structure designed in step 2. Account-level data is applied as merge fields or tags on the contact record per the customer's chosen strategy. Campaign membership is mapped as tags. We run the import in test mode against a subset (500-1,000 records) before the full load to verify field mapping and status assignment.
Automation and workflow rebuild handoff
We deliver the written Workflow and Sequence inventory to the customer's marketing team, covering every active SalezShark automation with its trigger conditions, filter logic, and downstream actions, plus a recommended Mailchimp Customer Journeys equivalent. We do not rebuild automations in Mailchimp as part of the migration scope. We include a Mailchimp automation setup guide for common use cases (welcome series, re-engagement, post-purchase) so the customer's team can prioritize rebuilds efficiently.
Cutover and post-migration verification
We freeze new writes in SalezShark during the final cutover window, run a delta export for any records modified during the migration, and complete the final Mailchimp import. We deliver a row-count reconciliation report comparing SalezShark record counts to Mailchimp audience member counts, flagging any discrepancies. We include a post-migration checklist covering domain verification, 2FA setup, unsubscribe link placement, and sender reputation warm-up. We do not provide ongoing Mailchimp admin support or training as part of the standard migration scope.
