Reserved Email Addresses
Security-Focused List
We compiled a list of 1250+ email addresses that should be reserved by admins for security concerns.
Did you know? In our paid plans, organizations can have members that belong to an "admin" or a "user" group – and the "user" group is not permitted to add aliases that equal one of the reserved email addresses below. We also restrict the "user" group from having an email address that starts with, ends with, or equals "admin", "administrator", "webmaster", "hostmaster", "postmaster", and "ssl".
