Signup checklist · From submission to inbox

Before you submit a signup form,
make sure you know where
your confirmation email will go

If you don’t want to use your personal email to sign up for a website, you can prepare a separate address for registrations. But if a confirmation email doesn’t arrive, the inbox may not be the problem: check whether the form was submitted successfully, whether the platform has sent the email, and whether the address is still active.

Start the checklist Open inbox

First, find out where the email is in the process

01

Form submitted

Look for a signup confirmation page, order, or registration number.
02

Platform sends the email

Check whether the email is sent immediately or after a review or queue.
03

Email arrives in your inbox

It’s received only when it appears in your inbox.

“Submission successful” doesn’t mean “email delivered.” This page can’t check third-party sending logs or guarantee that a platform accepts disposable addresses or delivers email immediately.

01 / Before you submit

Allow time for the confirmation email, and save your inbox link

Check only items you’ve verified. An unchecked item means it hasn’t been confirmed—not that a problem was detected. Your selections stay on this page and aren’t sent to a server.

You copied the complete address After copying the address from the home page, compare the full email address in the form. Check for extra spaces, missing characters, or an old address filled in automatically by your browser. The email is expected to arrive before the address expires Check the inbox’s actual time remaining, then read the organizer’s email instructions. The default expiry is 3 hours. You can extend it by 3 hours at a time, up to 24 hours per inbox. You saved the complete inbox link somewhere private Save the complete link from your browser’s address bar, not just the email address. The link contains access credentials, so don’t post it in a public group chat or share it with the event organizer. You won’t need this inbox for long-term account recovery Make sure you won’t need this address to reset a password, receive payment confirmations, or get ongoing notifications. Use an email account you can keep access to for important accounts and messages arriving more than 24 hours later.

02 / While submitting

Check three things on the website

A button click, a disabled button, or a loading spinner is just a page response. Stay on the signup platform and check the three items alongside this checklist before returning to your inbox. Don’t assume signup succeeded just because no error appeared.

If the platform says it doesn’t accept this domain, refreshing Tmprelay won’t change that. Use an address that meets the platform’s requirements. An email forwarding alias isn’t guaranteed to pass its checks either.

The email address in the form

Compare it character by character with the current address in your inbox. Watch for autofill, incomplete pasting, or the form keeping the old address after you clicked “Use another.”

The website’s success message

Look for a signup confirmation page, record, or number. If the page still shows a required-field error, pending payment, or a verification-code prompt, complete the platform’s steps first.

The confirmation email instructions

Check whether the platform actually promises to send an email and whether it mentions manual review, batch sending, or a notification before sending starts. Some forms show the signup result only on the website.

You found a success record and checked the sending instructions If you haven’t confirmed both, leave this unchecked for now.

03 / After submitting

Check possible reasons for the delay in this order

This page can’t access your inbox. Check it on the home page, then return here to update your checklist. Refreshing checks only for emails that have arrived; it can’t prompt a third-party platform to send one.

You’re checking the same inbox address you used to sign up If you changed addresses along the way, find the saved link to the original inbox. The new inbox won’t receive messages sent to the old address. If the old inbox has expired or been deleted, update your address on the platform. There’s enough time left for the email to arrive Use the countdown on the home page. If review could take until tomorrow or longer, don’t rely on extensions alone—update your address on the platform to one you can keep using. You refreshed the inbox manually on the home page and saw a success message The inbox checks for new messages automatically every 7 seconds. A successful manual refresh displays “Inbox refreshed.” An error means only that this check didn’t succeed; it doesn’t tell you whether the sender sent an email. You checked the sender’s review, queue, or resend instructions Follow the times and steps shown by the platform. There’s no universal rule that an email will arrive after a few minutes. If the sender’s stated timeframe has passed, contact the platform with your signup details.

Check and refresh your inbox Reopen your previous inbox

Suggestions are based on your checklist, not email delivery detection

What should you do next?

Check the items above, then view your suggestions. They’ll point out what still needs confirming; they won’t claim an email is lost or guarantee that the next one will arrive.

JavaScript is disabled, but you can still use this checklist: use your regular email if you’ll need long-term account recovery; return to the signup platform if the address or success record is unclear; extend the inbox if it may expire too soon; otherwise, verify the remaining items and follow the sender’s instructions while you wait.

04 / Still no email

In these situations, don’t submit again just yet

Submitting again won’t necessarily make the confirmation email arrive sooner. It may create multiple signup records, trigger sending limits, or invalidate a verification code you’ve already received.

Tmprelay receives email only. It can’t lift a third-party platform’s rate limits, complete its review, or retrieve messages that haven’t left the sender’s queue.

The platform says your signup is under review or queued

Keep your signup number and wait according to the instructions on the page. If no sending time is given, ask the organizer first. Don’t submit another form just because your inbox is empty.

The resend button is still cooling down, or you’ve been told you’ve tried too many times

Wait until the platform allows you to try again; don’t bypass its limits. Cooldowns and blocking rules vary by platform, so this page can’t provide a universal retry interval.

You’ve received several verification-code emails

Check the sender’s instructions and the time of each message. Some platforms accept only the most recently generated code. Don’t mix up codes from different emails; if needed, request a new one using the platform’s process.

After it arrives

Move anything you need to keep out of your temporary inbox

When the confirmation email arrives, verify the event name, signup status, and date. Once the inbox expires or is deleted, its messages can’t be recovered. Saving the link won’t extend its lifetime.

Save your signup details

Save your signup number, the organizer’s name, and any important confirmation details in your own notes or files. Keep personal information secure, and don’t share verification codes or your complete inbox link publicly.

Note the event time

Record the date, time zone, and how to enter. If an entry link will arrive in a separate email before the event, check that your address will still be active then. Don’t save only the first “Signup successful” email.

Plan for future notifications

For ongoing notifications, consider signing in and creating a forwarding alias, then updating your email address on the signup platform. An alias won’t automatically take over your old temporary address. For important account recovery, use a reliable email account you can keep access to.

Finish this signup once you’ve checked everything

Use your current inbox for one-time confirmations. For ongoing notifications, sign in without a password using your personal email and create up to 100 forwarding aliases. Aliases can receive email, but can’t reply to the organizer on your behalf.
