Missing verification emails?
Find out where things went wrong

A verification email not arriving at your temporary address doesn’t always mean there’s a problem with your inbox. Check each step from the address to delivery, rule out what you can, then decide what to do next.

Start the check Check your inbox

“It didn’t arrive” can have different causes

Don’t assume every missing email is just delayed. Identify the likely cause first so you don’t waste resend attempts on the wrong address or an expired inbox.

Not sent successfully
The sending page shows an error, rate limit or incomplete verification. Clicking the send button doesn’t prove the email entered the delivery process.
Address mismatch
A character is missing, an old address was pasted, or the website kept the value you entered earlier. Resending to the same wrong address won’t help.
Possible delivery delay
If the page confirms the email was sent and the address is valid, the sender may be queuing or retrying delivery. Waiting doesn’t guarantee the email will arrive.
Address has expired
Once a temporary address expires, it can no longer receive email, and messages already there can’t be recovered. A new address won’t inherit the old address’s verification codes.
The platform doesn’t accept temporary email
Some websites block disposable email addresses. If you see a clear rejection, use an address the website accepts instead of trying more temporary addresses.

Four quick checks · No code needed

Select what you see

Check the questions in order, or change your answers at any time. If you find more than one issue, start with the address and its expiry. Your answers stay on this page and aren’t sent to a server.

0 of 4 checked
Does the address on the sending page exactly match the current address on the home page?

Check the value actually entered, not just your browser’s autofill suggestion. Make sure you haven’t used an old address from before you switched.

Is the email address you used still active?

Check the time remaining beside the address on the home page. A verification code’s expiry is separate from the lifetime of the email address.

What does the sender’s page actually say?

Go by the page’s message, not a disabled button. If there’s a cooldown or extra verification, follow the website’s instructions first.

How long has it been since the last confirmed send?

Follow the sender’s guidance first. One or two minutes is just a suggested time before your first check—not a delivery deadline or guarantee.

Once you’ve answered all four questions, you’ll see what to do first. Your recommendation updates whenever you change an answer.

Your next step

Complete the four checks above first

You don’t need to share your inbox credentials or verification code. Check the address, its expiry and the sender’s page to rule out common causes.

Check the address · Start with the source

Verify the address before resending

Don’t rely on memory or copy from an old screenshot. Start with the full address and time remaining currently shown on the home page.

Copy the full address from the home page →

  1. Copy the full address from the home page

    Select “Copy address” to include every character on both sides of @. If copying doesn’t work, select the entire address manually and check for missing characters or extra spaces.

  2. Check the value in the sending form

    Reopen the email field and compare it with your current address. If the website still shows an old value, update and save it before requesting a new code.

  3. Make sure there’s enough time to finish

    If the address is still active but time is running short, select “Extend by 3 hours” on the home page. Check the countdown afterward. Extending the address doesn’t extend the code’s expiry.

Changing addresses isn’t the same as refreshing: a new address destroys the old one and its emails. Old codes won’t move to your new inbox. Update the address on the sender’s website before requesting another code.

What can each action actually do?

No single button can control the whole delivery process. Knowing the difference between checking your inbox and asking a website to send another code can save you a lot of wasted effort.

What refreshing, extending, resending and changing addresses can—and can’t—do
Action When to use it What it can’t do
Refresh inbox manually The address is active, the website confirmed it sent the email, and you want to check for new messages. It can’t speed up the sender or send another verification code.
Extend by 3 hours The address is still active, but you need more time to finish signing up. It can’t restore an expired address or make an old code valid again.
Request another code on the original website You’ve checked the address and resolved any sending issue, or the old code has expired—and the website allows another request. It can’t bypass the website’s cooldown, security checks or restrictions on temporary email.
Use an address the website accepts The website clearly rejects temporary email, or you need long-term account recovery and ongoing notifications. An email alias isn’t guaranteed to be accepted. Follow the sender’s rules when choosing an address.

If the email still hasn’t arrived and the sending page provides no useful information, you can’t investigate further from this page. Contact the sender through its official help channels to ask about sending records or email restrictions.

Important limitations

Check delivery without sharing your code

Never share your verification code, inbox credentials or a link containing credentials with support staff. If you need help, describe when it happened, what you did and any error message. Hide sensitive details in screenshots.

Use an email address you control long term and can recover for banking, work, paid subscriptions and accounts you may need to recover. A forwarding alias can help with ongoing notifications, but it’s not a substitute for account recovery and may not be accepted by every platform.

Check first, then make sure the next email goes to the right place

Return to the home page to check the address and time remaining. If it’s still active, keep using it instead of switching just to “see if it works.” For ongoing email, consider a forwarding alias.
