Disposable email
Crazymailing.com
CrazyMailing’s terms describe a free, receiving-only inbox that requires no account, while its homepage also promotes account features. Requesting a replacement address immediately deletes the previous mailbox and its contents, so replacing an address can remove mail already received.
For people who need temporary incoming mail, the key distinction is whether they use a guest inbox or register for an account.

Guest and account inboxes expire differently
The provider’s FAQ and homepage give these access and retention details, checked 2026-10-31.
- Guest mailbox: lasts one day from the most recent opening, according to the FAQ.
- Account mailbox: lasts seven days after the latest sign-in, according to the homepage.
- Account messages: kept for up to thirty days, according to the homepage.
- Replacement address: immediately destroys the earlier address, according to the FAQ.
- Account features: private inboxes, less visible domains, attachments, and simultaneous mailboxes, according to the terms.
Advertising funds the free account
The provider describes the service and its account as free, with advertising funding the service rather than a paid tier. The FAQ also says there is no paid step behind a trial countdown, while the terms state there is no charge or paid tier.
These are provider descriptions of the service price and account terms, not a statement about any separate costs a reader might incur outside the service. Before registering, check that the free account’s mailbox retention and access rules fit the intended use.
Incoming mail is the mailbox’s full scope
CrazyMailing describes its mailbox as receiving-only: it accepts incoming email, but users cannot send or reply to messages. That makes it a temporary receiving inbox, not a two-way email account.
The guides serve a different purpose from the mailbox: the provider says they cover disposable-email terminology, detection, use cases, and mechanics.
Ask support about domain and account details
Before registering, ask support to clarify the service’s legal identity and history, which domains are available, and any setup requirements or integrations. These details affect how a temporary inbox would fit into an existing workflow.
The provider says bugs, abuse reports, and corrections can go through its contact page. Its terms also list an email contact and the contact page for questions.
Copied addresses start incoming delivery
The provider says an address begins accepting incoming mail when copied, and messages appear without a manual refresh. Its homepage describes this as delivery through a server-pushed connection rather than repeated fetching.
For display, the provider says it removes scripts, stylesheets, iframes, and inline styles from message HTML. It also says message content appears in an isolated frame with scripts removed.
Attachments are offered as downloads rather than rendered in the page, according to the provider. Signed attachment links remain valid for five minutes, according to the provider’s about page.
Free accounts add privacy and attachments
The provider says a free account includes private inboxes and domains it describes as less visible, alongside simultaneous mailbox access. It also states that account mailboxes cannot be opened by strangers.
Account holders can access attachments, while guests can read message text but cannot access attachments, according to the FAQ. The provider also says it does not store IP addresses or access logs; this is its own privacy statement.
Expiry, access, and automation narrow use
The provider’s terms impose limits on mailbox replacement, access, recovery, and automation.
- Requesting a different address deletes the previous mailbox and its contents immediately, according to the homepage.
- Guest inboxes are accessible to anyone who knows or guesses the address, according to the homepage.
- Deleted or expired mail cannot be recovered because the provider says it keeps no archives or backups.
- The provider says it has no API, feed, or endpoint for automation, and that driving pages with scripts breaches its terms.
- Some sites may refuse the service’s addresses when its domains reach blocklists, according to the provider.
- The service accepts incoming mail but does not let users send or reply, according to its about page and FAQ.
Check the mailbox’s retention and access conditions against your intended use before registering.
Compare inboxes by retention and access
Compare disposable-email services by how long inboxes remain available, whether they support sending, and what account access requires. Privacy statements, attachment rules, and paid terms also matter; check how each service defines those conditions before choosing an inbox.
Short-lived receiving needs define the fit
The provider describes CrazyMailing as a free, receiving-only disposable inbox that requires no account. The provider advises against using disposable addresses for accounts that may need recovery, including banking, government, employment, or shipping.
The provider also says an address measured in hours is unsuitable when a message may arrive weeks later. Check the relevant site’s terms and local law; the provider says some sites prohibit disposable addresses in their terms.

Mailbox terms answer practical questions
How long does a guest inbox remain available?
The guest inbox remains available for one day after the user’s last visit, according to the provider’s about page, checked 2026-10-31. The FAQ instead describes the period as one day from the most recent opening. Both descriptions tie guest retention to activity in the inbox.
When does an account mailbox expire?
The provider’s homepage says account mailboxes last seven days after the latest sign-in, while its FAQ says a mailbox lasts a week after the most recent visit. These pages describe different triggers: sign-in on the homepage and a visit in the FAQ. The provider gives both conditions.
Who can open a guest inbox?
Anyone who knows or guesses the guest address can open its inbox, according to the provider’s homepage. The FAQ adds that guest mailboxes have no password or owner. Treat the address as the means of access, rather than as a private login.
Can deleted or expired messages be recovered?
No. The provider says deleted or expired messages cannot be recovered because it has no archives, backups, or recycle bin. It also states that deleted mail is not archived or backed up. Keep any message needed later outside this mailbox.
What attachment limits and restrictions apply?
The provider’s FAQ says attachments larger than five megabytes are refused, while the message still arrives. Its about page says attachments over five megabytes are skipped and messages over ten megabytes are silently rejected. The FAQ also lists thirty-five refused executable formats.
Does the service support API access or automation?
The provider says it has no API and does not plan to offer one. Its terms also state there is no API, feed, or endpoint for automation, and that driving pages with scripts breaches the terms. The FAQ describes automated access as closed off.
Proceed only within the receiving-only terms
Fits if… temporary incoming mail is enough and the mailbox’s expiry conditions suit the task.
Probably not if… the address must support replies or future account recovery; the provider excludes sending and advises against recovery-sensitive accounts.
Main risk… replacing an address deletes its earlier mailbox, and deleted mail cannot be recovered. Before registering, check the mailbox lifetime and whether the intended account may need recovery.
