Temp mail not receiving emails? How to fix it

Most missing emails come down to four causes: the site refuses disposable domains, the sender is slow, the address was mistyped, or the inbox has not been refreshed. Work through the checks below in order. Each one takes under a minute.

Eight checks, in order

Wait two minutes, then refresh. On the free plan the inbox updates when you tap the refresh button; it does not check on its own. Premium checks every 5 seconds while the app is open. There are no push notifications, so keep the app open while you wait.
Compare the address letter by letter. Copy it with the copy button instead of typing it. One wrong character sends the email to a different inbox, and you will never see it.
Make sure the site actually sent something. Some forms only send the email after you press a final button, solve a captcha or confirm a phone number. Look for a "check your inbox" message on the site.
Ask for one resend. Pressing resend again and again can hit the sender's own limits and delay every copy.
Switch to another domain. If nothing arrives after a resend, the site is probably refusing the domain. Delete the address or create a custom one on a different domain from the domain list, then sign up again. TempMail has 23 free domains, so you can try several.
Check the time. Messages are deleted from our server 12 hours after they arrive. A code you were sent yesterday will not be there today.
Read "Too many requests" as a pause. If you refresh many times in a row, the server asks you to wait. Leave it for a minute and refresh once.
Open the rest of the list. The inbox shows the newest message first and folds older ones under a "Show more" link. A code sent before a newsletter can be hiding there.

Why sites block temp mail domains

Many sign-up forms check the domain of your address against a list of known disposable email providers and reject anything on it. Public lists such as check-mail.org track these domains, and large platforms say so openly: GitHub's help pages state that it will not verify disposable email addresses.

A blocked domain looks like one of two things. Either the form shows an error as soon as you enter the address, or the form accepts it and the email simply never arrives. Switching domain fixes the second case more often than the first, because each list covers a different set of domains.

If a site rejects every domain you try, it does not want disposable addresses at all. Use an email alias or your real address there. The disposable email vs email alias guide explains the difference.

Why an email can arrive late

Verification emails from large services go out through queues, and most arrive within a minute. During busy periods or after several resends, delivery can take a few minutes. Waiting two minutes before you change anything saves you from creating a new address while the first email is still on its way.

What TempMail cannot receive

Attachments. The text and HTML of a message arrive, but attached files are not shown.
Mail to a different spelling. Addresses are matched exactly, so a typo in the form goes to someone else's inbox.
Mail older than 12 hours. It is deleted from the server automatically.

Still nothing?

Email contact@notragnar.com with the domain you used (the part after the @), the site you signed up to and roughly when. That is enough for us to check whether the domain is being refused. Please do not send the code or any personal details.

Questions

Why is my temp mail not receiving the verification code?

Usually the site blocks disposable domains, the address was mistyped, or the inbox has not been refreshed. Copy the address with the copy button, wait two minutes, tap refresh, and if nothing arrives after one resend, switch to a different domain.

How long does a verification email take to reach a temp mail inbox?

Most arrive within a minute. During busy periods it can take a few minutes, so wait two minutes before resending or changing the address.
