Overview
Lifeline Suite is a healthcare and nonprofit operations platform that exports data as structured spreadsheet files — typically EXPORT_Constituents.xlsx, EXPORT_Codes.xlsx, and EXPORT_Gifts.xlsx. These files contain contact records, relationship metadata, referral physician links, and gift or billing history. Mailchimp organizes everything in a flat Audience model: one contact record per email address, with custom merge fields for structured data and tags for categorical assignments. The two models diverge significantly — Lifeline Suite is relationship-centric with hierarchical referrals and donor segments; Mailchimp is contact-centric with tag-based segmentation. We map constituent names, addresses, and contact details to Mailchimp standard fields. We translate Lifeline Suite segments, categories, and referral links into Mailchimp Tags and Groups. We preserve constituent codes, branch identifiers, and account references as custom merge fields. We surface the deduplication decisions your team must make before the import — email-only contacts, phone-matched duplicates, and multi-branch records that may represent the same person. Workflows, sequences, and automations from Lifeline Suite do not migrate — Mailchimp's automation engine operates differently and those must be rebuilt.

Object mapping
Each row shows how a Lifeline Suite 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.
Lifeline Suite
Constituent (EXPORT_Constituents.xlsx)
Mailchimp
Contact
1:1Lifeline Suite's constituent record maps directly to a Mailchimp contact. Email address serves as the primary key for all contacts — any constituent record missing an email address is flagged for manual review before import begins. Mailchimp requires a valid email address for every subscriber in the audience, so contacts without email must be resolved by your team through data lookup, client communication, or exclusion from the migration batch.
Lifeline Suite
Constituent firstname / lastname
Mailchimp
Merge Fields (FNAME, LNAME)
1:1First name and last name from Lifeline Suite map directly to Mailchimp's built-in FNAME and LNAME merge fields. When Lifeline Suite stores full names in a single field, we split on the first space delimiter — any middle name, suffix, or additional given names are appended to the last name merge field to preserve the complete name without data loss.
Lifeline Suite
Constituent email address
Mailchimp
EMAIL (primary key)
1:1Email address functions as the Mailchimp subscriber key for all contact records. Duplicate email addresses appearing across multiple Lifeline Suite branches or referral entries create merge conflicts during import. We flag these duplicate scenarios and your team decides whether to keep a specific Lifeline record, merge contacts into one entry, or suppress duplicates from the migration batch entirely.
Lifeline Suite
Constituent phone / mobile phone
Mailchimp
Merge Field (PHONE)
1:1Phone and mobile phone numbers from Lifeline Suite map to a custom PHONE merge field in Mailchimp. When Lifeline Suite stores both phone types, we prioritize the mobile number over the primary phone line. International formatting is standardized to E.164 during the import process to ensure compatibility with Mailchimp's validation requirements and SMS integration features.
Lifeline Suite
Constituent address fields
Mailchimp
Merge Fields (ADDRESS)
1:1Lifeline Suite address components including street, city, state, zip, and country map to Mailchimp's structured ADDRESS merge field format. If your Lifeline Suite export stores address as a single concatenated text block rather than separate columns, we parse it into individual components before import using established US address parsing patterns and common international address formats.
Lifeline Suite
Constituent code / category
Mailchimp
Tag
1:1Lifeline Suite constituent type codes including Donor, Patient, Member, and Referral along with their sub-categories from EXPORT_Codes.xlsx translate directly into Mailchimp Tags. Each constituent receives one or more tags based on their assigned codes and category classifications. Your team confirms the tag naming convention and reviews the tag vocabulary during the planning phase before migration commits.
Lifeline Suite
Branch / location identifier
Mailchimp
Tag or Group
1:1Lifeline Suite deployments with multiple branches store a branch identifier per constituent in the export files. We translate these branch codes into Mailchimp Tags using a consistent naming pattern such as Branch-NYC or Branch-LA. This approach enables location-based segmentation in Mailchimp campaigns without requiring a separate custom field, and tags can be organized under Groups for easier management.
Lifeline Suite
Referral physician / source link
Mailchimp
Merge Field (REFERRING_PHYSICIAN)
1:1Lifeline Suite referral links and referring physician names have no built-in Mailchimp equivalent, as Mailchimp contact records are isolated without native relationship modeling. We create a REFERRING_PHYSICIAN custom merge field to preserve this data during migration. When referral sources are categorical rather than free-text, we also apply a corresponding tag per your tagging convention — your team decides during the planning phase.
Lifeline Suite
Gift / donation record
Mailchimp
Merge Field (GIFT_AMOUNT, GIFT_DATE)
1:1Gift amounts and dates from EXPORT_Gifts.xlsx map to GIFT_AMOUNT and GIFT_DATE custom merge fields on each constituent contact record. Mailchimp has no native financial reporting capabilities — these merge fields are available for segmentation purposes such as targeting high-value donors for specific campaigns, but they do not generate revenue dashboards or financial reports within the Mailchimp platform.
Lifeline Suite
Unsubscribed / bounced status
Mailchimp
Suppression handling
1:1Lifeline Suite unsubscribe and bounce records are preserved during the import process. Unsubscribed contacts from Lifeline Suite import with suppressed status in Mailchimp — the platform automatically blocks any send attempts to these contacts. Bounced contacts require a pre-import decision from your team: import as unsubscribed contacts, suppress them manually before import, or attempt email validation and re-import valid addresses before the migration batch finalizes.
Lifeline Suite
Intake date / enrollment date
Mailchimp
Merge Field (ENROLLMENT_DATE)
1:1Lifeline Suite intake or enrollment timestamps map to a custom ENROLLMENT_DATE merge field stored on each contact record. This date field supports multiple marketing use cases including re-engagement campaign targeting — for example, identifying and messaging contacts who enrolled more than 12 months ago with a win-back sequence to reactivate dormant constituents.
Lifeline Suite
Custom constituent properties
Mailchimp
Custom Merge Fields
1:1Lifeline Suite custom properties beyond standard constituent fields map to Mailchimp custom merge fields during migration. Mailchimp Standard plan allows up to 40 merge fields per audience — we prioritize the most marketing-relevant properties including branch code, category tags, referral source, and intake date. Any custom properties that exceed this merge field limit are documented in the mapping plan for manual handling or alternative storage solutions.

Migration approach
Pull and audit Lifeline Suite export files
FlitStack AI retrieves EXPORT_Constituents.xlsx, EXPORT_Codes.xlsx, and EXPORT_Gifts.xlsx from your Lifeline Suite instance. We audit each file for column completeness, duplicate email addresses, date format consistency, and records missing an email address entirely. The audit report identifies which fields will map to Mailchimp merge fields, which will become Tags or Groups, and which records cannot import without an email address — those are flagged for your team to handle manually before the migration runs.
Build the code-to-tag and field-to-merge-field mapping plan
Using the audit results, we build a detailed mapping plan: Lifeline Suite category codes translate to Mailchimp Tags, branch identifiers become location Tags, and referral source fields become either Tags or custom merge fields based on data type. We deliver this plan as a spreadsheet your team reviews and approves before any data moves. If Lifeline Suite has more custom properties than Mailchimp's 40-merge-field limit, we prioritize the fields that drive marketing segmentation and document what must remain in Lifeline Suite or a separate system.
Clean and deduplicate contact records
We apply standardization rules: phone numbers reformatted to E.164, addresses parsed into Mailchimp's structured ADDRESS field components, and date fields converted to ISO 8601. Email deduplication runs on the full constituent list — contacts sharing an email address across multiple Lifeline branches or referral entries are flagged for your decision: keep the most recent record, merge contact records, or suppress duplicates. Unsubscribed and bounced contacts are handled per your suppression preference before the import batch is built.
Create Mailchimp audience, merge fields, and tag set
We create the Mailchimp audience using the API, add all custom merge fields identified in the mapping plan, and pre-populate the tag vocabulary so the tag set is ready before records land. Tags are organized into Groups (by category type, branch, and gift type) matching the Lifeline Suite classification hierarchy. Mailchimp's GDPR and marketing consent fields are configured to match the consent flags carried over from Lifeline Suite — consented contacts import as subscribed; non-consented contacts are suppressed or import as unsubscribed based on your instruction.
Run a sample migration and generate a field-level diff report
A representative slice of contacts — typically 100 to 300 records spanning different constituent types, branches, and gift history levels — migrates first. We generate a field-level diff showing every source field value and its corresponding Mailchimp merge field result. Your team verifies that tags applied correctly, referral physician names landed in the custom field, and gift amount merge fields populated. The diff report is the approval gate before the full migration commits.
Run full migration, capture delta, and monitor first send
The full constituent list migrates in batched API calls against Mailchimp's import endpoint. After the import completes, a delta-pickup window (24–48 hours) captures any new records or updates made in Lifeline Suite during the cutover window. We monitor Mailchimp's first campaign send to confirm deliverability and flag any remaining bounced contacts. A rollback snapshot is retained so your team can restore the pre-migration state if reconciliation uncovers data issues within the first send window.
