Disposable email address
email for only one or very few contacts
Disposable email addresses (DEAs) are unique email addresses employed for specific contacts or uses. The term may refer both to alias- or forwarding-based addresses and to temporary email addresses or temporary inboxes created for short-term use, often with a planned lifespan measured in minutes, such as 10 to 60 minutes.
This is primarily done so that if the email address becomes compromised or utilized in connection with email abuse, the address owner can easily cancel (or "dispose" of) it without affecting their other contacts.
Uses
DEAs allow a unique email address for every sender or recipient combination. They are commonly used for online registration, free trial signups, one-time downloads gated by email verification, forum and community participation, software testing and development of email-based workflows, and reducing the exposure of a primary email address when using non-essential services.
It can be employed in scenarios where someone may sell or release an individual's email address to spam lists or other unethical entities. The common situations of this type include online registration for sites offering discussion groups, bulletin boards, chat rooms, online shopping, and file hosting services.
If a DEA is jeopardized/used in a manner not intended by the owner, it can be easily cancelled at any time.
DEAs typically forward to one or more genuine email mailboxes where the owner receives and reads messages. The contact with whom a DEA is shared never learns the owner's real email address.

Why this record matters
The phrase “email for only one or very few contacts” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q3131356. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
