How can I stop or modify my Messages while I’m blocked from accessing my account?

If you have lost access to your account due to a billing issue or going over your free account quota, your Campaigns and Messages that you have set up will continue to send.

Should you have a Campaign or Message that needs to be stopped while you’re blocked, please reach out to support@mixpanel.com.
