My Mailchimp campaigns stopped loading in BytePhase. What should I check?

Usually the API key. If Mailchimp rejects the saved key, for example because it was deleted or replaced in your Mailchimp account, BytePhase switches the Mailchimp integration off and asks you to reconnect. Open the Mailchimp integration in Settings, enter a current API key with its server prefix and save. Your campaign list and reports will load again, and you can carry on adding contacts.
