Disposable email
Crazymailing.com
CrazyMailing provides free, receiving-only disposable inboxes without requiring an account. Guest inboxes can be opened by anyone who knows or guesses the address, while a free account adds private inboxes and attachment access. The distinction matters if mail might contain sensitive information or need to be recovered later. People comparing temporary inboxes may find the key question is whether guest access or account retention suits their use.

The mailbox receives mail, not replies
CrazyMailing accepts incoming messages, but its addresses cannot send or reply to email. The provider’s guides discuss disposable-email terminology, detection, use cases, and mechanics; they do not change the mailbox’s receiving-only purpose.
For guest mail, the provider says access relies on a random cookie token that is not connected to a name, device, or location. That description does not make a guest inbox private: the provider also says anyone who knows or guesses its address can open it. Check which access type applies before sending mail to the address.
Advertising funds the free account
The provider says the service and its accounts are free, with advertising funding the service and no paid tier. Its terms also describe accounts as free and say there is no paid step above them.
The homepage and FAQ characterize the offer as having no paid tier or trial countdown.
A copied address starts receiving mail
The provider says an address starts accepting mail when copied, and incoming messages appear through a server-pushed connection without repeated fetching. Messages are displayed without refreshing, according to its guides.
The provider says it displays message HTML in an isolated frame after removing scripts, stylesheets, iframes, and inline styles. Attachments are downloads rather than page-rendered content, with signed links valid for five minutes, according to the About page. Guests can read message text but cannot access attachments; the provider says attachments are available on free accounts. Check the account condition if receiving attachments matters.
Check retention before relying on an inbox
Before using a disposable inbox for a task, ask which domains are currently offered and whether those domains suit the sites involved. A provider’s domain list can affect whether an address is accepted.
Keep the answers specific to the mailbox and the task rather than assuming another service’s setup applies.
Expiry and access rules narrow use
Replacing a guest address immediately deletes the previous mailbox and its contents, and the provider says deleted mail cannot be recovered. It also says account mailboxes last seven days after the latest sign-in, while individual messages are kept for up to thirty days; attachments last only as long as their messages.
Guest inboxes have no password or owner, and anyone who knows or guesses the address can open one. The provider says it may delete mailboxes without advance warning or a later explanation. These access and deletion terms make the inbox unsuitable for mail that needs durable privacy or recovery.
Driving pages with scripts breaches the terms, and the provider says it does not publish an API, feed, or endpoint for automation. They also prohibit bulk account creation on another site against that site’s rules. Loading message images can notify the sender that a message was opened and roughly when, according to the provider. Several details are missing; they are listed under What we could not confirm.
Free accounts add private inbox features
The provider says a free account adds private inboxes, attachment access, and simultaneous mailboxes.
- Private access: the provider describes account mailboxes as inaccessible to strangers, unlike guest inboxes.
- Longer retention: the provider says account mailboxes remain available longer than guest mailboxes.
- Mail handling after expiry: messages arriving after a mailbox is gone are dropped, not stored or answered.
- Logging: the service says it does not store IP addresses or access logs.
- Contact route: bugs, abuse reports, and corrections can be sent through the contact page.
These are provider statements, not independently verified privacy or performance findings. Compare the account’s retention conditions with how long you need access to a message.
Use guest inboxes only for temporary mail
A guest inbox suits a task where receiving mail is temporary and the contents do not need private access or recovery. The provider warns against using the service for banking, government, employment, healthcare, shipping, domain registration, or matters involving money or identity.
The provider says disposable addresses are legal in jurisdictions it is aware of, while particular acts may still be unlawful and sites may prohibit their use in their terms. Site rules and local law still matter. Check whether the account or service terms permit the use you have in mind.
Compare disposable inboxes by access terms
Compare disposable inboxes by the domains they offer, how long inboxes and messages remain available, whether sending is supported, and whether automation has API access. Check per-user limits, paid plans, and what each provider’s privacy statements actually cover. Ask how deleted messages and expired addresses are handled before relying on any mailbox for delayed mail.

Questions about guest mail and accounts
What happens when a guest address is replaced?
Replacing a guest address destroys the earlier address and its mailbox, according to the provider’s FAQ. The FAQ says the previous mailbox does not remain available after replacement. Treat replacement as a deletion point, not as a way to keep several guest inboxes accessible.
What does account retention mean?
The provider says an account mailbox remains for a week after the latest visit, while each message lasts no longer than thirty days. Those are separate retention conditions: mailbox availability is tied to the latest visit, and an individual message has its own maximum lifetime. Check both when timing matters.
Can guests open attachments?
Guests can read message text but cannot access attachments, according to the provider’s FAQ. The provider says attachments are available on free accounts. If a guest receives a message with a file, the text may be readable while the attachment remains inaccessible.
How are oversized messages and attachments handled?
The About page says messages over ten megabytes are silently rejected, while attachments over five megabytes are skipped. The FAQ describes oversized attachments as refused while the message still arrives. Check the distinction between a message exceeding its limit and an attachment exceeding its separate limit.
Which attachment formats are refused?
The provider says it refuses executable formats, including exe, msi, bat, ps1, vbs, jar, apk, and dmg. The FAQ describes a broader list of refused formats; check its current attachment rules if a file type matters to your task.
Is a short-lived address suitable for delayed mail?
The provider says a mailbox lasting only hours is unsuitable when the needed message may arrive weeks later. That warning concerns the timing mismatch between address lifetime and expected delivery. Compare the expected arrival time with the mailbox’s stated retention before using a temporary address.
The decision turns on inbox privacy
Fits if… the task needs temporary incoming mail and does not depend on private guest access or later recovery.
Probably not if… the workflow requires sending or replying, or keeping messages available beyond the provider’s retention conditions.
Main risk… guest access is open to anyone who knows the address, and replacing it deletes the earlier mailbox. The provider says its terms may change and continued use after a change counts as acceptance.
