Pseudonymity

is the ability to prove a consistent identity without revealing one's actual name, instead using an alias or pseudonym.
[means] [t]he identity of the sender (identity meaning the user's real email address or other identifying information such as IP address data) is not known to the recipient but is known to the tool company — and the recipient may be able to reply to the message.[1]

Overview[]

"Pseudonymity is strengthened when less personal data can be linked to the pseudonym; when the same pseudonym is used less often and across fewer contexts; and when independently chosen pseudonyms are more frequently used for new actions (making them, from an observer's or attacker's perspective, unlinkable)."[2]
