Disconnecting a store view, or uninstalling the extension, removes the Mailchimp store: the shopping data we synced into your account. The admin says it in these words, and this page means exactly the same thing:
The Mailchimp store and the ecommerce data we synced to it will be removed. Your audience, contacts, tags and campaigns are not affected.
The distinction is deliberate. A Mailchimp store is a projection of data your Magento store already holds, so it can be rebuilt. Your audience is your own asset, built from consent you collected and work your team did, so the extension never deletes from it.
What happens, in detail
| Outcome | What it covers |
|---|---|
| Survives | Contacts, subscription status, tags, merge fields, member activity, segment definitions, campaigns, templates, customer lifetime value, and campaign reports for opens, clicks and bounces |
| Rebuilt if you reconnect | Products, orders, carts, store customers, promo rules and codes. Minutes on most stores, with original order dates |
| Degraded until you reconnect | Purchase-based segments stop matching, though the segments themselves survive and repopulate. Product recommendations and e-commerce automations pause rather than break |
| Not restored | Campaign attribution, the record of which Mailchimp campaign drove which order. It is kept locally, so a full uninstall removes it and reconnecting does not rebuild it |
Disconnect or uninstall?
Disconnect is the reversible one. In Marketing → Intuit Mailchimp → Configuration, at the store-view scope, disconnecting releases that store view from its Mailchimp store. Other connected store views keep working.
Uninstalling the module removes the extension and its local data as well. Run bin/magento module:disable Ebizmarts_MailchimpMarketing, then bin/magento module:uninstall -r Ebizmarts_MailchimpMarketing: the -r flag is what removes the data and performs the same Mailchimp-side cleanup as Disconnect. Without it, the command asks a second question, whether to remove the database data, and that answer defaults to No, so confirming only the first prompt removes the code but leaves the Mailchimp store and the local data behind.
Either way, what reaches Mailchimp is the same: the Mailchimp store goes, the audience stays.
If you reconnect
Reconnecting picks a fresh Mailchimp store or creates one, and the shopping data refills from Magento. Orders keep their original dates, so your history is not flattened into the day you reconnected.
Your contacts never left, so segments, automations and reporting that rest on audience data carry on. What needs a moment is anything resting on purchase data: those segments repopulate as orders sync back, and paused recommendations and automations resume.
A Mailchimp store that already holds another store view’s shopping data cannot be reused. That protects its owner exactly the way yours is protected.
Store views you have not connected
Subscribers only sync from store views that are connected to Mailchimp. That is deliberate: the extension will not push contacts toward an audience you did not choose to connect, so a store view you have left alone stays entirely out of your Mailchimp account.
The consequence is worth knowing in advance rather than discovering later. If you have connected some store views but not others, subscribers who sign up on an unconnected view stay in Magento and will not appear in your audience. Connecting the view runs the initial backfill for it, existing subscribers included, and no subscriber is left out by date: every contact who is still subscribed is collected, however long ago they signed up. The history window you pick in the wizard’s step 3 governs order and cart history, not subscribers. Re-syncing and command-line tools covers both.
Changing audiences instead
If your goal is to point a store view at a different audience rather than to leave, that is a deliberate flow with its own guide. See Choose your audience, which covers the disconnect-and-reconnect path and what to expect.
Disconnecting and reconnecting also appears in Troubleshooting as a repair step for a few specific problems. It is safe to use that way. This page is here so you know what it does before you reach for it.
