Amusingly, I am trying to log in to the dashboard to reboot my nodes, but it requires a verification code which was sent to my email, which is hosted on Linode.
Consider signing up to a service like MXGuardian that your MX records can point to, and that then forward email to your server. This will give you an “emergency inbox” that you can use in cases like this (might also help with spam depending on how you are currently dealing with that).
