# Mailchimp integrations > Sync subscribers, segments, ecommerce data, and campaign engagement between Mailchimp and the rest of your stack on tray.ai. **Canonical page:** https://tray.ai/connectors/mailchimp-integrations/ **Categories:** Marketing **Connects through:** Connector **Documentation:** https://tray.ai/documentation/connectors/service/mailchimp ## Overview Mailchimp is the email marketing platform behind millions of newsletters, promotions, and automated customer journeys. Its value depends on the audience behind it, and that data usually starts somewhere else, in a CRM, a web form, an online store, or an event platform. tray.ai's Mailchimp connector reads and writes audience members, merge fields, interest groups, segments, ecommerce stores, customers, and orders, and pulls campaign reports back out, so subscriber data stays current and engagement flows back to sales and analytics without CSV exports. ## Use cases ### CRM-to-Mailchimp Audience Sync Upsert Mailchimp audience members whenever a contact or lead is created or updated in Salesforce, HubSpot, Pipedrive, or SugarCRM. Map lifecycle stage, owner, region, and account fields to Mailchimp merge fields and interest groups, so segments are built on the same data your sales team sees. - One upsert per change instead of nightly CSV imports - Merge fields and interest groups that match CRM values - Segments that stay accurate as records change ### Form and Event Signups Straight into the Right Audience Add new subscribers from Typeform, Wufoo, Formstack, Unbounce, WordPress, or Eventbrite registrations the moment they submit, with the right interest groups and segment membership set from their answers. Check addresses with ZeroBounce first so bad emails never reach your audience. - New contacts are emailable within seconds of signing up - Answers become merge fields and interests, not lost data - Cleaner audiences and better deliverability ### Ecommerce Customer and Order Sync Push customers and orders from Shopify, Magento 2, Square, or a custom store into Mailchimp's ecommerce store, and keep orders updated as they ship or are refunded. Mailchimp's purchase-based segments and product recommendations then work from complete order history. - Purchase-based segments without a native plugin for every store - One Mailchimp store fed by several sales channels - Order updates reflected as they happen ### Campaign Engagement Back to Sales Pull campaign email activity, recipients, and member activity from Mailchimp reports and write opens, clicks, and unsubscribes onto the matching CRM contact or as tasks for the account owner. Sales sees which accounts are engaging without logging into Mailchimp. - Email engagement visible on CRM records - Follow-up tasks for highly engaged contacts - Unsubscribes respected across systems ### Unsubscribe and Consent Sync When someone opts out in Mailchimp, update the do-not-email or consent fields in your CRM, and archive or update Mailchimp members when consent is withdrawn elsewhere. Every system holds the same answer about who can be emailed. - Consent kept consistent across marketing and sales tools - Lower risk of emailing people who opted out - An execution log for every consent change ### Campaign Reporting in One Place Collect campaign lists, recipients, and email activity on a schedule and load them into Google Sheets, a data warehouse, or a Slack digest. Combine them with CRM pipeline or store revenue to report what each campaign actually produced. - Scheduled reporting with no manual exports - Campaign results next to pipeline and revenue - A weekly digest in the channel your team reads ## Templates ### HubSpot Contact Updated → Mailchimp Audience Upsert Keeps a Mailchimp audience in step with HubSpot by upserting the member and its merge fields whenever a HubSpot contact changes.

Exporting and re-importing them leaves audiences out of date and loses fields that segmentation depends on. **How Tray.ai helps:** tray.ai upserts members as records change, maps source fields to merge fields and interest groups in one place, and handles create-or-update logic so duplicates don't build up. ### Mapping Merge Fields and Interest Groups Mailchimp stores custom data as audience-specific merge fields and interests identified by IDs, not names. Point-to-point integrations hard-code those IDs and break when an audience changes. **How Tray.ai helps:** The connector lists merge fields, interest categories, and interests for each audience, so workflows can look IDs up at run time instead of hard-coding them. ### Keeping Consent Consistent An unsubscribe in Mailchimp that never reaches the CRM leads to sales emails to people who opted out, and the reverse is just as risky. **How Tray.ai helps:** tray.ai listens for Mailchimp audience webhooks and CRM changes and updates both sides, with an execution log for every change. ### Reaching Endpoints the Connector Doesn't Cover Mailchimp's Marketing API is large, and teams sometimes need an endpoint that no prebuilt operation covers. **How Tray.ai helps:** The connector's raw HTTP request operation calls any Mailchimp Marketing API endpoint with the same authentication, so there's no separate custom integration to build. ## Agent features ### Search Audience Members (Data Source) Find Mailchimp members by email or name across audiences, so an agent can check whether someone is subscribed and what their status is before acting. ### Get Member Activity and Notes (Data Source) Read a member's recent activity and notes, giving an agent context on how a contact has engaged with email. ### List Campaigns and Email Activity (Data Source) Retrieve campaigns, recipients, and email activity so an agent can report on performance or find engaged contacts to follow up with. ### List Audiences, Merge Fields, and Interests (Data Source) Look up audiences, merge fields, interest categories, and segments so an agent picks the right IDs when it writes data back. ### List Ecommerce Customers and Orders (Data Source) Read customers and orders in a Mailchimp ecommerce store to answer questions about purchase history. ### Upsert Audience Member (Agent Tool) Create or update a member with merge fields and interests, so an agent can add or correct subscriber data from any conversation or system. ### Archive or Delete a Member (Agent Tool) Archive or permanently delete an audience member to act on unsubscribe or deletion requests. ### Add Member to a Segment (Agent Tool) Add a member to a static segment so an agent can place contacts into the right campaign audience. ### Create or Update Ecommerce Orders (Agent Tool) Create customers and orders, or update an order's status, keeping Mailchimp's purchase data current. ## Learn more - Intelligent Integration: https://tray.ai/platform/intelligent-ipaas/ - Merlin Agent Builder: https://tray.ai/platform/merlin-agent-builder/ - Agent Gateway for MCP: https://tray.ai/platform/agent-gateway/ - Book a demo: https://tray.ai/contact/
