Overview
Moving from OptifiNow to Mailchimp is a directional shift from a full enterprise CRM to an email marketing platform, not a lateral platform swap. OptifiNow stores Contacts, Accounts, Leads, Opportunities, custom objects, and engagement history across a non-publicly-documented schema. Mailchimp stores Audience Members, Tags, Segments, Campaigns, and Automations with no native opportunity, account, or custom object concept. We migrate Contacts as Mailchimp Audience Members (preserving email, name, phone, and opt-in status), map OptifiNow Accounts to Tags or merged profile fields, and move email engagement history where available via Mailchimp's API. We do not migrate Opportunities, Deals, custom objects, or workflow logic because Mailchimp has no equivalent structure. OptifiNow's non-public schema requires a discovery session before we can enumerate all migratable fields, and we disclose this discovery dependency in the pricing and timeline estimates.
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.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a OptifiNow 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.
OptifiNow
Contact
Mailchimp
Audience Member
1:1OptifiNow Contacts map directly to Mailchimp Audience Members using email as the dedupe key. We preserve first name, last name, email address, phone number, and opt-in status (hs_email_optout or equivalent). Custom contact fields from OptifiNow migrate to Mailchimp merge fields (FNAME, LNAME, PHONE, and any custom text or date fields). We do not migrate social collaboration data, contact source attribution, or ownership assignments as Mailchimp has no equivalent Owner field.
OptifiNow
Account
Mailchimp
Tag or Merge Field
many:1OptifiNow Accounts do not have a direct Mailchimp equivalent. We typically aggregate Accounts as Tags on the corresponding Contact record (e.g., tag: 'Account: Acme Corp') or merge account name into a custom merge field (ACCOUNTNAME). If the customer has many-to-one account hierarchies, we flatten them to a primary account tag. We do not create a separate Account object in Mailchimp because no such object exists.
OptifiNow
Lead
Mailchimp
Audience Member (segmented)
1:1OptifiNow Leads migrate to Mailchimp Audience Members with a segmentation tag (e.g., tag: 'Lead Source: Referral') to distinguish them from converted Contacts. We preserve lead source, assignment rules, and any lead score custom field as a Mailchimp merge field or tag group. Unqualified leads that the customer does not want in Mailchimp are excluded based on a scoping decision made during discovery.
OptifiNow
Opportunity
Mailchimp
Not migratable
lossyOptifiNow Opportunities (deals with pipeline stages, probabilities, and close dates) have no Mailchimp equivalent. Mailchimp has no deal, opportunity, or pipeline object. We exclude Opportunities from the migration scope entirely and document this gap in the handoff report so the customer's admin does not expect deal data in Mailchimp. If deal tracking is required post-migration, the customer must evaluate a CRM addition or replacement.
OptifiNow
Marketing Automation Sequence
Mailchimp
Not migratable
lossyOptifiNow stores automated email sequences, triggers, and delays as internal workflow definitions that do not export as runnable automation packages. We document OptifiNow sequence templates as plain-text records in the handoff inventory, including trigger conditions, delay values, and email content. The customer rebuilds these in Mailchimp's Automation builder. This is a disclosed limitation that affects marketing teams relying on automated nurture sequences.
OptifiNow
Custom Object
Mailchimp
Not migratable
lossyOptifiNow supports custom objects via API, but Mailchimp has no custom object support whatsoever. Any OptifiNow custom objects (e.g., Policy, Loan, Subscription, Property) cannot be migrated to Mailchimp. We document custom object types and field definitions in the handoff inventory. If the customer needs this data visible post-migration, they must either maintain OptifiNow for that data or evaluate a different destination platform.
OptifiNow
Engagement: Email
Mailchimp
Contact Activity
1:1OptifiNow email engagement logs (sent, opened, clicked) linked to Contacts migrate to Mailchimp as contact-level activity history. We map the original send timestamp and engagement type (Opened, Clicked) to Mailchimp's contact activity feed via the Mailchimp API. Historical email content from OptifiNow does not migrate as Mailchimp campaign records; we document the email body and subject line in a plain-text activity log attached to the contact.
OptifiNow
Engagement: Call, Meeting, Task, Note
Mailchimp
Not migratable
lossyOptifiNow stores call logs, meeting records, tasks, and notes as activity objects linked to Contacts and Accounts. Mailchimp tracks only email-related activity (opens, clicks, unsubscribes) on individual contacts. Call duration, meeting attendance, task status, and note content have no Mailchimp equivalent. We exclude these engagement types from the migration and note them in the handoff report. If call or meeting logging is required, the customer needs a separate CRM or a Mailchimp integration with a calling tool.

Migration approach
Discovery session and schema enumeration
We schedule a live walkthrough of the customer's OptifiNow tenant to enumerate all custom fields, custom objects, pipeline stages, workflow configurations, and engagement types in use. This discovery phase produces a written schema inventory that defines the final migration scope. Until discovery is complete, we cannot confirm whether all expected fields have a Mailchimp merge field target or whether custom objects must be excluded. Discovery is a fixed-fee engagement phase that precedes the production migration proposal.
Contact and account extraction with deduplication
We extract Contacts, Accounts, and Leads from OptifiNow via API using the enumerated schema. We run a deduplication pass on email addresses, flag records with missing or invalid email addresses, and present the customer with a duplicate resolution decision (merge, keep newest, keep oldest). Accounts are aggregated to Tags attached to their corresponding contacts. The extraction output is a validated CSV and JSON dataset ready for Mailchimp import.
Mailchimp audience setup and merge field configuration
We create the destination Mailchimp Audience with merge fields mapped to OptifiNow source fields identified during discovery. Tags are structured per the account aggregation strategy. Suppression list segments are pre-created so that the suppressed-contact batch can be imported directly into the suppression list rather than the active audience. Domain authentication (SPF, DKIM) is confirmed or set up per Mailchimp's pre-import checklist to protect deliverability from day one.
Test migration to Mailchimp Sandbox
We run a test load into a Mailchimp test Audience using a subset of production data (typically 100-500 records) to validate merge field mapping, tag application, duplicate handling, and suppression list behavior. The customer reviews the test audience in Mailchimp, spot-checks record accuracy, and signs off before production migration begins. Any mapping corrections happen at this stage, not in production.
Production migration in batches
We run the production migration in batches of up to 50,000 contacts per import job, using Mailchimp's bulk import API. Active contacts load into the main Audience; suppressed contacts load into the Suppression List. Engagement history (email opens, clicks) from OptifiNow maps to Mailchimp contact activity via the API after the base contact load completes. We emit row-count reconciliation reports after each batch so the customer can verify record counts against OptifiNow source totals.
Cutover, validation, and workflow handoff
We freeze writes in OptifiNow, run a final delta migration of any records modified during the migration window, then deliver the handoff package. The handoff package includes: the full contact inventory in Mailchimp with tag documentation, the automation sequence inventory as plain-text templates, the excluded-object list (Opportunities, custom objects, call logs, meetings, tasks), and the OptifiNow data export archive. We support a 72-hour hypercare window for reconciliation issues. Workflow rebuild and automation reconstruction in Mailchimp are not included in standard scope.
