Overview
Moving from Simplero to Mailchimp is a consolidation move: you are extracting your email audience and contact data from an all-in-one course, community, and CRM platform and placing it into a dedicated email marketing tool. We migrate contacts with their tags, segment memberships, and email history. We cannot migrate Simplero products, course enrollments, community posts, Deals pipelines, help desk tickets, or Automation Flows because Mailchimp does not have equivalents for any of these. The Simplero-to-Mailchimp integration documented in Simplero's help center is a forward sync from Simplero into Mailchimp for new purchases, not a migration path for existing data. We perform the extraction via Simplero's API (Scale tier or above required) or CSV export, clean the data, map tags to Mailchimp Tags and segments to Mailchimp Segments, and import via Mailchimp's bulk import API with status-preserving suppression handling. Post-migration, your admin must rebuild any email automation logic in Mailchimp Customer Journeys from a written Flow inventory we deliver.

Object mapping
Each row shows how a Simplero 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.
Simplero
Contact
Mailchimp
Audience Member
1:1Simplero contacts map directly to Mailchimp audience members via email address as the dedupe key. We preserve first name, last name, email, subscription date, and status (subscribed, unsubscribed, bounced, cleaned). Custom Contact Fields require pre-creation in Mailchimp as merge fields before import; we flag any Simplero custom fields that exceed Mailchimp's 255-character text merge field limit and truncate or flag for manual review. Contacts without email addresses are excluded and listed separately in the reconciliation report.
Simplero
Tag
Mailchimp
Tag
1:1Simplero tags are flat key-value labels applied to contacts. These map directly to Mailchimp Tags, which are per-audience labels usable for segmentation and filtering. We export the full tag list from Simplero, resolve each to the corresponding Mailchimp audience tag, and apply them during contact import via the bulk import API. Tags with special characters or non-ASCII characters are normalized to ASCII slug format for Mailchimp compatibility.
Simplero
Segment
Mailchimp
Segment
lossySimplero segments are dynamic filter groups built from contact property conditions. We document each segment's filter logic (field, operator, value) as a written specification and recreate them as Mailchimp Segments using Mailchimp's segment query syntax. Because Mailchimp segments use different field names and operators than Simplero, we perform a logic translation during scoping. Active segment membership is preserved by exporting contacts matching each segment filter and creating Mailchimp static segments alongside the dynamic equivalents for immediate use.
Simplero
Email Broadcast
Mailchimp
Campaign
1:1Individual Simplero email broadcasts map to Mailchimp Regular Campaigns. We export subject line, from name, from email, HTML body content, and any attached images. Mailchimp's campaign type (regular, plaintext, variant) is set during scoping based on the Simplero broadcast format. Campaign stats (opens, clicks, bounces) do not transfer because they are historical metrics tied to the source send; we note this in the reconciliation report so the customer sets fresh baseline expectations in Mailchimp.
Simplero
Email Sequence
Mailchimp
Customer Journey
lossySimplero multi-step automation sequences contain content (each email step's subject and body) but not the Flow logic (triggers, delays, branching conditions). We export the content of each email step, map it to a Mailchimp Customer Journey, and document the original trigger conditions and delay rules as a written specification. The customer's admin rebuilds the Customer Journey trigger and timing in Mailchimp using our documented specification. This is manual work requiring attention to the original Flow logic.
Simplero
Product
Mailchimp
No equivalent
1:1Simplero products (courses, memberships, digital downloads, coaching programs) have no Mailchimp equivalent. Mailchimp does not have a product catalog, enrollment tracking, or access management object. We export the product list as a CSV reference table for the customer's records but do not import it. If the customer needs product data in Mailchimp, they must add products manually as audience fields or use a third-party integration like Shopify.
Simplero
Order and Purchase
Mailchimp
No equivalent
1:1Simplero order records (product, price, date, payment gateway, refund status) have no native Mailchimp equivalent. Mailchimp's e-commerce integration connects only to supported platforms (Shopify, WooCommerce, Magento, BigCommerce, Stripe) and does not accept generic order data. We export orders as a CSV for record-keeping. Refund flags and partial payment statuses are lost unless the customer manually creates custom audience fields to hold them.
Simplero
Member and Enrollment
Mailchimp
No equivalent
1:1Simplero members are contacts with active access to a product or course. Enrollments track which member has access to which product and when. Mailchimp has no enrollment or access management object. We cannot migrate this data structurally. If the customer needs to track course access in Mailchimp, they must manually create tag-based access groups or use an external LMS integration post-migration.
Simplero
Automation Flow
Mailchimp
Customer Journey (manual rebuild required)
1:1Simplero Flows (triggers, delays, branching conditions, action chains) are not exposed via the public API or any export mechanism. We do not migrate Flow logic. We deliver a written inventory of every active Simplero Flow documenting its trigger event, step sequence, condition branching, and action chain so the customer's admin can rebuild it in Mailchimp Customer Journeys. This is a significant manual effort for complex nurture sequences.
Simplero
Deal and Pipeline
Mailchimp
No equivalent
1:1Simplero Deals and pipeline stages (available on Skyrocket tier) have no Mailchimp equivalent. Mailchimp is not a sales CRM and does not have Opportunity, Pipeline, or Deal objects. We export the Deals list as a CSV reference file but do not import it. If the customer needs to track sales data post-migration, they must use a separate CRM tool.
Simplero
Ticket and Help Desk
Mailchimp
No equivalent
1:1Simplero help desk tickets (subject, status, assignee, conversation thread) have no Mailchimp equivalent. Mailchimp does not have a support ticketing feature. We export ticket records as a CSV reference file for record-keeping. The customer must evaluate dedicated help desk tools (Zendesk, HelpScout, Front) if they need to maintain support history post-migration.

Simplero gotchas
Contact quota enforcement can silently block migrations
Automation Flows have no export or API access
Unsubscribe records do not transfer between systems
API access requires Scale tier minimum
Blog RSS import supports a narrow set of platforms
Mailchimp gotchas
Contact count includes unsubscribed and non-subscribed records
Automation workflows cannot be exported
Account suspensions trigger silently during migration
Template HTML is Mailchimp-specific and may not render in other platforms
E-commerce data requires active store connection

Migration approach
Tier and API access verification
We confirm the customer's Simplero plan tier during scoping. If the customer is on Scale or Skyrocket, we request API credentials and test the contact, tag, and segment endpoints. If the customer is on Starter, we confirm CSV export as the extraction method and document the resulting data gaps (missing tags and segment membership). We also confirm the target Mailchimp plan tier based on audience size to ensure contact limits are appropriate.
Contact field audit and Mailchimp merge field pre-creation
We audit every Simplero contact field including custom contact fields, system fields (subscription date, source, tags, segments), and any enrichment data. We compare against Mailchimp's standard merge fields (FNAME, LNAME, EMAIL, PHONE, ADDRESS) and flag any Simplero custom fields that need pre-creation in Mailchimp as merge fields. Fields exceeding Mailchimp's 255-character text limit are flagged for truncation or manual handling. Tags and segments are catalogued and mapped to their Mailchimp equivalents at this stage.
Simplero data extraction
For Scale and Skyrocket customers, we extract contacts via the Simplero API in paginated batches with rate-limit handling. We pull contacts with full tag arrays and segment membership. Email broadcasts and sequence step content are exported separately. For Starter-plan customers, we use CSV export and augment with tag data where available. Products, orders, enrollments, Deals, and tickets are exported as CSV reference files for record-keeping but are not imported into Mailchimp.
Data cleaning and transformation
We clean the extracted contact data: email validation, duplicate detection (by email address), status normalization (mapping Simplero status values to Mailchimp status values), tag normalization (ASCII slug conversion for special characters), and segment logic translation. Unsubscribe records are separated into a suppression list. Custom field values exceeding Mailchimp's 255-character limit are flagged and either truncated to 255 characters or moved to a notes field.
Mailchimp audience setup and bulk import
We create the Mailchimp audience using the customer-provided settings (default from name, from email, company name). We create any required merge fields and tags before import. The suppression list is imported first to establish the do-not-contact state. Contacts are then imported via Mailchimp's bulk import API in batches, with tag application and segment membership applied during import. Each batch is reconciled against the source record count before the next begins.
Campaign content migration and Customer Journey handoff
We import email broadcast content (subject, HTML body, images) as Mailchimp campaign drafts. Each broadcast is assigned to the correct audience and saved as a draft for the customer to review and send. We deliver the written Flow inventory and segment recreation specification as separate documents. The customer's admin rebuilds Customer Journeys using the Flow inventory; we are available for a migration support call to answer questions during the rebuild but do not rebuild Customer Journeys as a standard scope item.
Cutover and post-migration validation
We freeze writes in Simplero during the cutover window, run a final delta export of any contacts modified since the initial extraction, and import the delta into Mailchimp. We reconcile final record counts across Simplero source and Mailchimp destination and deliver a reconciliation report. We confirm email authentication (SPF, DKIM) is active in Mailchimp for deliverability. Post-migration, we do not provide ongoing admin support or Customer Journey rebuild as standard scope; these are separate engagements.
