Disposable
Optimize for short receipt
The address exists briefly and is often discarded after a code or link arrives.
Direct answer
What is the difference between an agent mailbox and disposable email?
Both can be temporary, but only an agent mailbox is designed as a controlled software identity and tool surface.
Direct answer
Disposable email primarily provides a short-lived address for receiving messages. An agent mailbox adds a defined owner, scoped authentication, APIs and tools, search, threads, attachments, events, extraction, optional approved sending, lifecycle controls, and a path to permanent or self-hosted identity. A temporary agent mailbox can be disposable without being an anonymous public inbox.

Comparison
Compare the operational contract
| Capability | Disposable email | Agent mailbox |
|---|---|---|
| Private access | Varies; some public inboxes expose messages. | Mailbox-scoped credential is expected. |
| Search and threads | Often minimal. | Part of the agent retrieval model. |
| Tool interfaces | Usually web or basic API. | CLI, SDK, MCP, API, webhooks, or events. |
| Sending | Often absent. | Policy-dependent persistent capability. |
| Permanent identity | Not the goal. | Can be promoted or self-hosted deliberately. |
| Operations | Provider-defined. | Explicit scope, retention, pause, rotation, and audit. |
Safe temporary use
A temporary agent inbox should still be private and scoped
Temporary does not need to mean public. The mails0 provisional flow issues a scoped credential, stores it locally, limits the mailbox to receive-only behavior, and expires the identity on a defined lifecycle.
That makes the address useful for legitimate agent and QA workflows while preserving a smaller trust boundary than a durable sending identity.
- Do not use a public shared inbox for sensitive codes.
- Do not use temporary addresses as durable recovery identities.
- Clean local credentials when the task ends.
- Respect external service terms and do not use temporary mailboxes for abuse.
Decision
Choose by the next action after receipt
-
01
Only receive one code or link
A private temporary mailbox is usually sufficient.
-
02
Search later or preserve a thread
Use a permanent agent mailbox with a named owner.
-
03
Send or represent an organization
Use an approved persistent identity and verified domain.
-
04
Own data and infrastructure
Self-host the agent mailbox application and define retention and operations.

Questions and answers
Related questions
Is a mails0 temporary mailbox public?
No. Access uses a scoped credential held by the client. The hosted provisional identity is receive-only and expires.
Can I use a temporary mailbox for account recovery?
Do not use an expiring address as a long-lived recovery channel. Promote to an approved permanent identity or use a durable provider account.
Why does an agent mailbox need search and threads?
Recurring agents need to retrieve relevant history and conversation context without loading or guessing across every message.
Start with a bounded inbox
Give the agent an inbox, then prove the workflow.
Start with a receive-only temporary mailbox. Move to a permanent identity or self-hosted deployment only after the workflow reaches a real email value event.
