If you subscribed to SMS text message alerts on our status page, you can unsubscribe from them by replying "STOP".
From StatusPage help:
End-users can unsubscribe from SMS notifications by replying STOP. (Note: some international carriers don't play nice with sending "STOP" messages, which may require those numbers to be unsubscribed through the UI by a Statuspage admin/team member).
If the "STOP" command does not work, please contact us by opening a support ticket.
