Overview
Moving from Streak to Mailchimp is a category shift, not a direct CRM replacement. Streak's core record is the Box, a Gmail-threaded CRM record with custom fields, deal stages, and owner assignment; Mailchimp has no deal pipeline equivalent and is built around Audience members, tags, segments, and campaign automation. We migrate what translates: Streak Contacts become Mailchimp Audience members with merge field mappings derived from Box custom properties, tag associations carry over as Mailchimp tags, and unsubscribe and contact status flags are preserved to protect deliverability. Box stage history, pipeline ownership, and deal-level metadata have no Mailchimp analog; we deliver a written inventory of these constructs for the customer to address manually. Mailchimp automations (Journeys) and Streak Mail Merge Campaigns are different cadence models and do not migrate as code; we document the mapping between them so the customer's team can rebuild sequences in Mailchimp's journey builder post-migration.

Object mapping
Each row shows how a Streak 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.
Streak
Contact
Mailchimp
Audience Member
1:1Streak Contacts (pulled from Gmail, stored with name, email, company affiliation, and custom contact properties) map to Mailchimp Audience members. Email address is the dedupe key. Status field (subscribed, unsubscribed, cleaned) is derived from Streak's contact-level opt-out state and mail merge suppression flags. First Name, Last Name, and company name map to Mailchimp merge fields FNAME, LNAME, and COMPANY. Any Streak custom contact properties map to Mailchimp account-level merge fields, which apply to all Audience members.
Streak
Box
Mailchimp
Audience Member (with custom field enrichment)
lossyStreak Boxes are not a native Mailchimp concept. We treat each Box as a subscriber context: the Box's associated Contact (or the Box creator if no Contact exists) becomes the Audience member, and Box custom property values are appended as merge field data on that member. Box stage and pipeline membership cannot map to a Mailchimp equivalent; we flag these as fields that require manual categorization via Mailchimp tags or segments post-migration. Box-level notes and attachments do not migrate to Mailchimp.
Streak
Tag
Mailchimp
Tag
1:1Streak Tags are flat labels applied to Boxes for filtering. Tags carry over as Mailchimp tags on the corresponding Audience member. Tags with no Boxes attached are included as empty tag lists for reconstruction in the destination. Mailchimp tags are purely descriptive and do not carry behavioral metadata (when the tag was applied, by whom) from Streak.
Streak
Pipeline + Stage
Mailchimp
Segment or Group
lossyStreak Pipelines and Stages define deal progression and have no direct Mailchimp equivalent. We map Pipeline-Stage combinations to Mailchimp Segments using static filter conditions on merge fields (e.g., a 'Sales Qualified' segment based on a custom field). Alternatively, if the customer prefers Groups, we map Stages to Groups within the Audience. The customer chooses the strategy during scoping. Stage history (when a Box moved between stages) is not migratable to Mailchimp's flat subscriber model.
Streak
Custom Box Properties
Mailchimp
Merge Fields
lossyStreak custom Box properties vary per pipeline (dropdowns, text fields, dates, numbers, checkboxes). We discover the full property schema per pipeline during the schema audit, then create corresponding merge fields in the Mailchimp Audience. Date properties map to Mailchimp date merge fields; number fields map to number merge fields; text and dropdown fields map to text merge fields. Mailchimp merge fields are account-level (apply to all members), so any per-pipeline property naming collisions require prefixing or disambiguation during the mapping phase.
Streak
Mail Merge Campaign
Mailchimp
Campaign (with Journey rebuild documentation)
1:1Streak Mail Merge Campaigns store recipient lists, email templates, send history, and open/reply tracking data. Recipient lists map to Mailchimp Audiences or Segments. Email template content migrates as Mailchimp template body text (HTML templates require re-creation in Mailchimp's template editor or import as raw HTML). Send history and open/reply metrics do not migrate because Mailchimp does not backfill historical engagement data for imported contacts beyond subscription status. We document the full campaign sequence cadence for the customer's team to rebuild in Mailchimp Customer Journeys.
Streak
Snippet
Mailchimp
Template Content
1:1Streak Snippets are templated email text blocks with merge variables (e.g., {{first_name}}). We export snippet content and variable syntax. Variable naming conventions differ: Streak uses double-brace syntax while Mailchimp uses asterisks around field names (*|FNAME|*). We transform snippet content during export, mapping merge variables to their Mailchimp merge field equivalents. Snippets used as standalone templates require re-creation in Mailchimp's template builder; snippets used as email body fragments can be imported as content blocks.
Streak
Task
Mailchimp
No equivalent
1:1Streak Tasks are Box-level action items with assignees and due dates. Mailchimp has no task management or activity tracking for contacts. We do not migrate Tasks. We flag the existence of open tasks during scoping so the customer can decide whether to re-create them in a separate task management tool (Asana, Trello, or a native Mailchimp integration with a project tool) or treat the migration as a clean handoff where open tasks are re-opened manually in the destination system.

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.
Streak gotchas
Free CRM tier removal catches long-time users off guard
Gmail-only is a hard migration boundary
Enterprise-only roles and data validation require permission remapping
Archived user Boxes require reactivation before export
Mail merge daily send limits gate campaign data export
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

Migration approach
Schema audit and contact volume assessment
We audit the Streak account across pipelines, Box schemas (per-pipeline custom properties), contact volume, tag taxonomy, mail merge campaign count, and any active Snippet library. We confirm whether the account is on a legacy free plan, Pro, Pro+, or Enterprise tier because API access scope and export speed vary by plan. We pair this with a Mailchimp Audience structure plan: single main Audience vs. multiple Audiences, merge field naming convention, and segment strategy for pipeline-stage categorization.
Contact and status extraction
We extract all Streak Contacts with their email address, name, company affiliation, custom contact properties, and subscription status. We separate subscribed, unsubscribed, bounced, and archived contacts into distinct export batches. Unsubscribe and bounce flags are preserved as Mailchimp-compatible suppression data to protect deliverability post-migration. We resolve any Contacts that exist as multiple Box associations and deduplicate by email address before export.
Box enrichment and custom property normalization
We extract Box records with their associated Contact reference, Pipeline assignment, Stage membership, custom property values, and Tags. We normalize per-pipeline property schemas into a flat property-value map for each Box, resolving type mismatches (dropdown labels to text, date formats to ISO 8601). Pipeline-Stage combinations that cannot map to Mailchimp segments are flagged for the segment rebuild inventory. Box stage history and deal values are excluded from the migration and noted in the handoff document.
Tag and Snippet export with merge variable transformation
We export all Tags with their Box associations and all Snippets with their merge variable syntax. Tags are exported as a tag-to-member mapping list for Mailchimp bulk import. Snippet content is exported and transformed: Streak double-brace merge variables ({{first_name}}) are converted to Mailchimp asterisk-notation (*|FNAME|*) during the export transform. Snippets that are pure HTML email templates are flagged for Mailchimp template re-creation.
Mailchimp Audience creation and merge field provisioning
We create the Mailchimp Audience in the destination account with the merge field schema derived from the Streak property audit. We apply Mailchimp's field type constraints (text, number, date, phone, address) and prefix any colliding field names to avoid duplicates. We configure the Mailchimp signup form settings and confirmation email preferences. We then import Contacts as Audience members with status flags, followed by tag assignments and merge field values from the Box enrichment.
Campaign inventory and automation handoff
We deliver a written inventory of every Streak Mail Merge Campaign, including recipient count, template content, send sequence order, and delay rules. We also inventory the Snippet library with transformed merge variable syntax. Both documents are formatted for the customer's email marketing team to use as a rebuild guide in Mailchimp Customer Journeys. We do not rebuild the sequences inside Mailchimp; that is a separate engagement or an internal marketing operations task. We support a one-week post-migration window to answer questions about the inventory documents.
