What happens when you disconnect

Disconnect from the same Connections page you connected on. You are asked to confirm, because the consequences differ depending on what you choose.

The sync stops

That is the guaranteed part. No new customers, leads or events arrive.

Your contacts and lists are not affected

Contacts already synced stay in your account, keep their list memberships, and remain mailable. Campaigns and automations keep working.

This is deliberate — your audiences should not evaporate because you unplugged a store.

Removing the synced records is a separate, heavier choice

The confirmation makes the distinction clear: erasing the synced records for an account removes the captured leads and order history, cannot be undone, and your contacts and email lists are not affected by it.

So there are two different actions:

• Disconnect — stop syncing, keep everything.
• Disconnect and erase — stop syncing and remove the synced record history.

Segments and reporting that depend on order history will change if you erase. A "bought in the last 90 days" segment has nothing to match on afterwards.

Reconnecting later

Reconnecting re-imports only what the provider still holds. It is not a restore: anything the provider has since deleted or aged out does not come back, and erased history is not recovered by reconnecting.

If you are disconnecting temporarily — changing agencies, moving a store — do not erase. Disconnect, and reconnect when ready.

Next: open Connections, and read the confirmation carefully — it distinguishes stopping the sync from erasing the history.
