Overview
Moving from eMarketeer to Mailchimp is primarily a contact-data migration with notable differences in segmentation logic and automation model. eMarketeer's Contacts, Campaigns, and engagement activity map to Mailchimp's Audience contacts, campaign history, and activity logs. The critical distinction is that eMarketeer segments evaluate real-time criteria rules while Mailchimp uses static audience membership; we snapshot current segment membership as a one-time contact list import rather than attempting to replicate live criteria logic. Custom properties from eMarketeer map to Mailchimp merge fields, subject to the 30-field standard limit (80 on Premium). eMarketeer Flows, event registrations, and SMS content do not have direct Mailchimp equivalents as transferable records; we deliver a written inventory of each flow and event type requiring manual reconstruction in Mailchimp Customer Journeys and event tools. We do not migrate forms or embedded form layouts as these are not reliably exportable from eMarketeer.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a eMarketeer 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.
eMarketeer
Contact
Mailchimp
Audience Member
1:1eMarketeer Contact records map 1:1 to Mailchimp Audience members. Email address is the dedupe key. Standard fields (first name, last name, email) map directly. Any eMarketeer custom properties map to Mailchimp merge fields, subject to the 30-field standard limit (80 on Premium). Lifecycle stage from eMarketeer cannot map to a native Mailchimp field; we store it as a custom merge field tag for segmentation reference at the destination.
eMarketeer
Campaign
Mailchimp
Campaign Report
lossyeMarketeer campaign records with send date, subject line, recipient count, and open/click metrics are preserved as a written campaign history document and optionally as a CSV import into Mailchimp's campaign archive. Mailchimp does not replicate eMarketeer's campaign object schema, so we provide a structured record of past campaign performance for the customer's reporting continuity.
eMarketeer
Segment
Mailchimp
Audience Tag or Static Segment
1:1eMarketeer segments with real-time criteria rules cannot replicate as live segments in Mailchimp (Mailchimp Pro supports criteria-based segments but with different rule syntax). We snapshot current segment membership at migration time and import the contact list as a Mailchimp static segment or tag group. The customer decides whether to use tags or static segments based on their Mailchimp plan tier. We document each original segment definition with its criteria for the admin to rebuild as Mailchimp segments post-migration.
eMarketeer
Flow
Mailchimp
Customer Journey
lossyeMarketeer Flows do not migrate as automation code because Mailchimp Customer Journeys use a different trigger-action model. We audit every active eMarketeer Flow during discovery, document the trigger type (form submission, segment entry, time delay, lifecycle change), the sequence of actions, and the recommended Mailchimp Journey equivalent. The customer's admin rebuilds the Journeys post-migration using this documented map.
eMarketeer
Event
Mailchimp
External Event Tool or Campaign Note
lossyeMarketeer event registrations and attendance records have no direct Mailchimp equivalent. We export event data as a structured CSV (registrant name, email, event name, registration date, attendance status) for the customer to import into their preferred event management tool (Eventbrite, Zoom, Splash, or similar) or to retain as a reference document. We do not create event records in Mailchimp.
eMarketeer
Custom Property
Mailchimp
Merge Field
1:1eMarketeer custom contact properties map to Mailchimp merge fields. We map text properties to text merge fields, date properties to date merge fields, and dropdown or multi-select properties to radio or dropdown merge fields respectively. Enumeration values from eMarketeer dropdowns are preserved as merge field options. If the account exceeds Mailchimp's 30-field standard limit (80 on Premium), we prioritize properties used in active segments and flag the rest for the customer to review.
eMarketeer
Email Template
Mailchimp
Template Reference Document
lossyeMarketeer email templates export as HTML blobs. We extract and preserve the HTML content, inline CSS, and image references as a structured document. Mailchimp's visual template editor with drag-and-drop components cannot reconstruct locked eMarketeer template blocks identically. We provide the raw HTML for the customer's designer to rebuild in Mailchimp, flagging any unsupported blocks (such as dynamic AMP email components) that require functional alternatives.
eMarketeer
Engagement Activity
Mailchimp
Contact Activity Log
1:1eMarketeer open, click, and unsubscribe events per contact per campaign aggregate into a contact activity history. We compile this into a structured contact activity log and import it into Mailchimp as a reference dataset. Mailchimp's real-time engagement tracking begins from the first send after cutover; historical open/click data from eMarketeer is preserved in the activity log for reporting continuity but does not populate Mailchimp's native engagement metrics dashboard.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
eMarketeer gotchas
Segment membership depends on real-time rules, not static lists
Flow automation triggers may not map 1:1 to destination platforms
Custom property schemas vary between accounts and lack a documented field registry
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
Pair-specific challenges
Migration approach
Discovery and export
We audit the eMarketeer account for contact volume, custom property schema, active segments, active flows, campaign history, event registrations, and SMS content. We derive the full property schema from the export data (eMarketeer does not publish a field registry) and flag any custom properties that exceed Mailchimp's field limits. We identify which segments use real-time criteria versus static rules and prepare the snapshot strategy accordingly.
Segment membership snapshot
We run a live query against each eMarketeer segment to capture current membership as a static contact list. These snapshots become Mailchimp static segments or tag groups at the destination. We document each segment's original criteria rule for the admin to reference when rebuilding criteria-based segments in Mailchimp Pro post-migration.
Custom property mapping and field creation
We map eMarketeer custom properties to Mailchimp merge fields by type (text, date, dropdown, radio). If property count exceeds the Mailchimp field limit, we prioritize properties active in segments and flows and present a reduction plan to the customer. We create the merge fields in the destination Mailchimp Audience before contact import begins.
Contact and campaign data migration
We import contacts into Mailchimp via the API using email as the dedupe key, with custom properties populated from the merge field mapping. We import suppressed and bounced contacts as a suppression list to preserve deliverability. Campaign history is compiled as a structured CSV and delivered as a reference document; we do not create campaign objects in Mailchimp. Engagement activity (opens, clicks, unsubscribes) aggregates into a per-contact activity log.
Template extraction and flow inventory
We export all eMarketeer email templates as HTML blobs with inline CSS. We document the template structure and flag any blocks (dynamic content, AMP components) that cannot reconstruct identically in Mailchimp. We deliver the raw HTML and a rebuild brief to the customer's designer. We separately deliver the flow inventory document listing every active eMarketeer Flow with its trigger type, conditions, and recommended Mailchimp Customer Journey equivalent.
Cutover and validation
We validate contact counts match between eMarketeer export and Mailchimp import, spot-check 20 to 30 records for data accuracy (names, emails, custom properties), and confirm suppression list integrity. We do not maintain a live sync between eMarketeer and Mailchimp post-migration; the customer sunsets the eMarketeer account after sign-off. We deliver the full migration documentation package including segment snapshots, property mapping, template HTML, and flow inventory within three business days of cutover.
