When synchronization with your newsletter tool stops working, the issue is usually related to outdated credentials or configuration. This article walks you through how to reconnect.
Signs of broken synchronization
New clients are not being synced to your email tool.
Data imports are running partially or with delays.
Synchronization stopped after an API key change.
How to reconnect
Check which tool is currently active (Mailerlite, Ecomail, Smartemailing, Mailchimp).
Verify your current credentials and make sure they are still valid.
Update or reconnect the integration in the admin panel.
For Mailchimp, if the authorization is invalid, consider disconnecting and setting up a fresh connection.
Test the synchronization with a single test client.
Post-reconnection checklist
A newly created client syncs to the external email tool.
No duplicate records are created.
Your team knows who manages the integration and where the credentials are stored.
Important: Always run a functional test after reconnecting. Saving your credentials alone doesn't guarantee that data is actually syncing correctly.
