Overview

What this migration involves

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.

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

SalezShark

What's pushing teams away

  • SalezShark users report that contact and lead data quality degrades without constant enrichment, leading to bounced emails and poor deliverability that undermines outbound campaigns.
  • The minimum 10-user license requirement for monthly billing catches smaller teams unexpectedly — they pay for 10 licenses even when only 3-4 team members use the system.
  • The platform lacks a publicly documented API, making it impossible to automate data extraction or build integrations without manual CSV exports, which limits migration flexibility and ongoing data sync options.

Choosing

Mailchimp logo

Mailchimp

What's pulling them in

  • Generous free tier with up to 500 contacts allows small teams to validate email marketing before committing to a paid plan.
  • Intuitive drag-and-drop email builder and 130+ templates let non-technical users produce professional campaigns without HTML or CSS knowledge.
  • 300+ native integrations, especially Canva and Shopify, make it easy to connect existing tools without custom development work.
  • Detailed open-rate, click-through, and campaign analytics give small businesses actionable insights without a dedicated marketing team.
  • One-platform consolidation of email campaigns, automations, landing pages, and ads reduces tool sprawl for lean marketing teams.

Object mapping

How SalezShark objects map to Mailchimp

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

maps to

Mailchimp

Audience Member

1:1
Fully supported

SalezShark 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

maps to

Mailchimp

Merge Fields and Tags (on Audience Member)

lossy
Fully supported

SalezShark 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

maps to

Mailchimp

Audience Member (with tag)

1:1
Fully supported

SalezShark 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

maps to

Mailchimp

Audience Merge Fields

lossy
Mapping required

SalezShark 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

maps to

Mailchimp

Not Migratable

lossy
Fully supported

SalezShark 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

maps to

Mailchimp

Not Migratable

lossy
Fully supported

SalezShark 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

maps to

Mailchimp

Customer Journeys (written inventory only)

lossy
Mapping required

SalezShark 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

maps to

Mailchimp

Audience Tags and Segments

lossy
Fully supported

SalezShark 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

maps to

Mailchimp

Not Migratable

lossy
Mapping required

SalezShark 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.

Pair-specific challenges

  • SalezShark has no API — extraction is CSV-only

    SalezShark does not publish API documentation for public use. All migration extraction relies on CSV exports from the UI, filtered by date range or record owner for large orgs. We coordinate with the customer's export credentials to pull Contacts, Leads, Accounts, Custom Fields, and Campaigns in batches. This limits what we can extract automatically and adds a manual step to the scoping phase. We confirm the export capability with the customer before confirming migration scope.

  • Mailchimp's 30-field audience limit constrains custom field migration

    Mailchimp limits audience merge fields to 30 on Essentials and Premium plans, and 80 on Mailchimp Premium. SalezShark Basic and above support unlimited Custom Fields. If the customer's custom field schema exceeds Mailchimp's limit, we prioritize fields used in segmentation and automation conditions, and flag the remainder as fields to create post-import. We surface this constraint during scoping so the customer can decide whether to upgrade to Mailchimp Premium or reduce their field count before migration.

  • Mailchimp counts unsubscribed contacts toward contact limits

    Mailchimp's pricing is based on total contacts in the audience, including unsubscribed and non-engaged members, not just active subscribers. Teams migrating large databases from SalezShark may find their Mailchimp bill higher than expected if they import inactive or bounced contacts. We recommend archiving or excluding contacts who have not engaged in 90+ days before import, and we flag this in the data cleansing phase so the customer can make an informed decision on list hygiene before migration.

  • Opportunities, Pipelines, and Workflow Automations have no Mailchimp equivalent

    SalezShark Opportunities, Pipelines, Workflow Automations, and Sales Engagement Sequences do not map to any Mailchimp object. Mailchimp does not track deal stages, pipeline velocity, or sales cadences. We do not migrate these records as data. We deliver a written inventory of every active Workflow, Sequence, and open Opportunity with its stage, value, close date, and owner so the customer's team can manually re-enter deal data and rebuild automations in Mailchimp's Journey builder post-migration.

  • Mailchimp text merge fields are limited to 255 characters

    Mailchimp's text merge fields have a 255-character maximum. Long-text fields from SalezShark (such as notes, descriptions, or multi-line address fields) are truncated at import. We flag any source field exceeding 255 characters during scoping and notify the customer before migration so they can decide whether to truncate, split into multiple fields, or handle the data outside of Mailchimp's merge field system.

Migration approach

Six steps for a successful SalezShark to Mailchimp data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Platform deep dives

Context on both ends of the pair

Strengths

  • Lowest entry price among SMB CRMs at $8/user/month with full feature tiers.
  • Native lead enrichment and company database included at no extra cost.
  • Custom fields, custom layouts, and field-level security available on Basic tier and above.
  • Multi-currency support and conversion scoring included without enterprise gating.
  • Separate database per customer for data isolation and logical security boundaries.

Weaknesses

  • No publicly documented API — all data movement relies on manual CSV exports and imports, which is a hard blocker for automated migrations.
  • Contact data quality depends heavily on the platform's own enrichment engine; exported data may not retain verified status if the destination lacks equivalent enrichment.
  • Minimum 10-user license requirement inflates cost for teams below that threshold, and additional users are billed at a flat $120/user add-on rather than prorated.
  • Workflow Automations and Custom Event Triggers are gated to Professional tier, meaning mid-market teams must pay $39/user/month to access automation capabilities.

Strengths

  • Free plan up to 500 contacts makes it the lowest-friction entry point for new email marketers.
  • Drag-and-drop builder and template library produce polished emails without design or coding skills.
  • Strong deliverability reputation backed by years of email infrastructure expertise.
  • 300+ native integrations cover the most common marketing stack combinations out of the box.
  • Consolidated platform for email, automation, landing pages, and ads reduces the number of tools small teams must manage.

Weaknesses

  • Contact-based pricing model charges for unsubscribed and non-subscribed records, inflating costs relative to competitors.
  • Five-step automation limit on Standard tier forces upgrades for basic customer journeys, a frequently cited frustration.
  • Template HTML is Mailchimp-specific and does not export cleanly for use in other email platforms.
  • Post-Intuit roadmap uncertainty means customers cannot confidently plan long-term platform investments.
  • Account suspension risk without clear pre-warning disrupts campaign scheduling for affected businesses.

Most migrations land between one and two weeks for accounts under 10,000 contacts with clean CSV exports and no custom field schema that exceeds Mailchimp's limits. Migrations with large contact volumes (50,000+), extensive custom field schemas requiring post-import field creation, or multiple active Workflow Automations requiring written rebuild documentation move to three to five weeks. The SalezShark-to-Mailchimp migration is faster than CRM-to-CRM migrations because there is no Opportunity, Pipeline, or Engagement history to map — the primary work is contact deduplication, field mapping, and tag strategy.
