A TempMail Cloud account can own multiple receive-only mailboxes and open them from one account session. Create a random or custom address while signed in, then select it from the profile menu. Each mailbox still has separate credentials for direct login when needed.
Why separate addresses instead of reusing one?
One address used everywhere becomes a single point of noise and correlation. Marketing, product testing, communities, and download sites all learn the same identifier. When spam starts, it is difficult to identify which service shared or leaked the address. Separate addresses create useful boundaries without requiring a separate full email provider for every task.
A practical structure might use one inbox for QA registrations, one for newsletters, one for shopping confirmations, and a fresh random inbox for truly one-off sign-ups. Because TempMail Cloud addresses do not automatically expire, the reusable ones can keep receiving later notices while the disposable identities remain easy to abandon.
Account login versus mailbox login
A registered account is the container that owns mailboxes. Its account email and password establish an authenticated session that can list and switch among owned addresses. A mailbox login uses the receive-only email address and that mailbox’s own password to open just that inbox.
This separation improves flexibility. Team members or test operators can keep a direct mailbox credential for a specific test identity, while the main account owner manages the collection. It also means you should not assume that remembering the account password automatically reveals every original mailbox password; the application stores password hashes, not readable originals.
Create and name addresses intentionally
Random names are useful when you want speed and weak linkage between sessions. Custom local names are better for QA roles and repeatable workflows: examples include neutral patterns for signup, billing-view, member, or reset testing. Avoid putting a real person’s name, phone number, customer ID, or confidential project name in a temporary address.
Choose from the active receiving domains presented by the interface. Domain availability is controlled by the administrator because DNS and mail-server configuration must be correct before an address can receive public mail. Creating the mailbox in the app does not by itself configure an unconnected domain.
Switch without repeated password prompts
The profile menu remembers a limited recent list in the browser and shows account-owned inboxes. Selecting an address should switch immediately when the browser has an authorized account or mailbox session. If the authorization is no longer valid, the safe fallback is a deliberate Login with mailbox credentials rather than silently granting access.
The recent list is a convenience view, not the full definition of which mailboxes exist. An older address can disappear from that browser list when the limit is reached and still remain active on the server. Save its credentials or keep it attached to your account if you may need it later.
Organize a 30-address allowance
TempMail Cloud’s current client-side recent history is designed around up to 30 mailbox references, which balances convenience and interface size. This does not mean the thirty-first mailbox automatically destroys an older server mailbox. The older reference may drop from the quick list while the mailbox remains accessible through an account or direct login.
Use a naming convention and a password manager note that records purpose, creation date, and whether the address is safe to delete. For QA, link the address to a test case or environment. For personal privacy, record only enough context to remember why the inbox exists.
Delete carefully and understand recovery
An owner can delete messages, while administrators can delete mailboxes when responding to user requests, abuse, or storage needs. The current admin workflow places deleted mailboxes in a 30-day recovery area before permanent purge. That safety window is not a substitute for keeping credentials or backing up important records.
After permanent deletion, the active application no longer serves that mailbox. Older server backups may retain a protected copy until backup rotation completes. Never create a critical dependency on administrative restoration; use a full permanent mailbox for anything important.
