Same browser, address still valid
Keeping your local credentials is necessary to try to restore access, but doesn't guarantee it will work. The server's expiration countdown continues while the page is closed.
Address lifespan · Email for game accounts
Signing up takes minutes,
but recovering your account may take months
How long does a temporary email last? Posttemp temporary inboxes are valid for 3 hours. Each renewal adds 3 hours, up to a maximum of 24 hours. Closing the page won't pause the countdown, and reopening it won't renew your address.
If you'll need login or recovery codes later, consider a forwarding alias or your own long-term email before signing up—not after your temporary address expires.
Plan for the account, not just the code
You may need the email more than once
Successful signup is only the first message. Whether and when a platform asks you to verify your email again depends on its own rules. These are possible stages, not a fixed timeline.

Now · Sign up
Verify that you can receive email
Signup codes are usually valid for only a short time. Check that the address is correct and the inbox is still active before submitting your registration.
Check your current inbox -
Later · Claim a reward
A reward may arrive in a separate email
A reward notification or eligibility confirmation may not arrive with the signup code. If you're still waiting, allow time and renew the address before it expires.
Estimate your wait window -
Next time · Log in again
A new device may require another code
A platform may email you again when you sign in on a new device or after a long period of inactivity. Saving your password doesn't mean you won't need email later.

At any time · Security check
You can't schedule a verification in advance
A platform may ask for extra verification if your sign-in environment changes. For an account you plan to keep using, don't rely solely on a short-lived countdown.
Choose based on account importance -
Much later · Recover your account
You'll still need to receive recovery emails
An expired temporary address won't reactivate just because a recovery email arrives. An alias also can't replace proof of purchase if the platform requires it.
Plan before you sign up
To switch from a temporary address to an alias, change the email address within the gaming platform. Posttemp won't migrate your account or automatically turn a temporary address into a long-term alias.

How long can
this email wait?
Enter the time remaining shown in your inbox, then add the number of renewals you plan to make. Each renewal adds 3 hours to estimate your theoretical wait window from now.
This is a duration calculation only. It won't create an address, request a renewal, or extend the code's validity. The maximum inbox lifespan limits how much time you can actually add; the inbox API response is authoritative.

This is a theoretical calculation and doesn't mean the server will allow every renewal. Check the inbox for the maximum lifespan and actual expiration time.

Three address types, three ways to plan ahead
Decide whether you'll need to receive these emails later before choosing an address for the signup form. Platforms may restrict certain email types; Posttemp can't guarantee that every platform will accept every address.
| What to consider | Posttemp temporary address | Posttemp forwarding alias | Your own long-term email |
|---|---|---|---|
| Do you need to log in? | No login required. Get an address from the homepage. | Verify your real email with a code for passwordless login, then create an alias. Each account can have up to 100 aliases. | Usually, you'll need to sign in to your email provider account. The exact process depends on the provider. |
| Where do future emails go? | View them in the web inbox. Valid for 3 hours by default; each renewal adds 3 hours, up to 24 hours. | Forwarded automatically to the real email address used to log in. The temporary inbox countdown doesn't apply. | Delivered directly to that inbox. Retention and access rules depend on the provider. |
| Does it depend on this browser's credentials? | Yes. You can try to restore access only if the address is still valid and the original credentials are saved. | Your dashboard session is saved in the browser. To manage aliases again, you need access to the real email account; if two-step verification is enabled, you'll also need an authenticator. | Depends on the provider's sign-in, session, and recovery systems. It doesn't rely on Posttemp temporary inbox credentials. |
| If it expires or becomes inaccessible | The address and emails are deleted on expiration and can't be recovered. We can't guarantee recovery if you lose your credentials. | Forwarding stops when an alias is disabled. An unavailable destination inbox, platform restrictions, or service changes may also affect email delivery. | Recover your account according to the provider's rules. Suspension, unpaid bills, or security restrictions may also affect access. |
| For important accounts | Not suitable as a long-term recovery address, especially for a primary account holding paid assets. | Can keep your public signup address separate, but doesn't guarantee account recovery or permanent availability. | For important accounts, consider an email address you control long-term with complete recovery options, and save the platform's recovery details too. |
| Next step | Receive an email now | Set up email forwarding | Check your email sign-in, recovery options, and multi-factor authentication settings. |
Email archiving is a separate feature: the dashboard keeps email records for 30 days. Don't confuse record retention with alias lifespan, or treat it as your only long-term backup. See our Privacy Policy.
After closing the page
Closing the page
doesn't save your address
Can you recover a temporary email after closing the page? You can try to reopen the same inbox only while the address is still valid and the original access credentials remain in this browser. Reopening the page doesn't renew it.
Don't assume the address shown on the page is the one you used before. When you return to the homepage, check the full address and time remaining before asking the platform to send a new code.
Check your address on the homepage →Cleared data, closed private browsing, or switched devices
These situations may make your original credentials unavailable. Saving the email address doesn't save access—you can't get back into the inbox from the address text or a screenshot alone.
Address expired or changed
Expired addresses and emails can't be recovered. Changing addresses creates a new inbox and invalidates the old one. The new address won't inherit the gaming account linked to the old address.
Your access credentials are the key to your inbox. Don't share them publicly or send them to strangers. If something seems wrong, contact support@posttemp.com, but contacting support doesn't mean deleted emails can be recovered.
Choose carefully before sharing an address
What email should you use for a game alt account?
Not every alt account is just for a day. Think first about how long you want to keep receiving email for it—that matters more than the account name.
Just trying it out
If you're only testing the signup process, don't plan to keep any assets, and are fine with losing access to future emails when the address expires, a temporary address is a straightforward option. Check that the platform allows it, and don't mistake successful signup for a guarantee you'll be able to recover the account later.
Key question: Are you okay with losing access to future emails?

An alt account you'll keep using
If you'll still be logging in, switching devices, or joining events in a few weeks, consider a forwarding alias before signing up. Emails go to your real inbox, while you use the alias on public forms. Make sure you can still access your real email and save the platform's own recovery details.
Key benefit: Keep receiving email without relying on a temporary inbox countdown
Set up ongoing forwarding →
A primary account with paid assets
Consider an email account you control long-term with complete recovery options. Save order details, recovery codes, and any identity information the platform requires, and enable its supported multi-factor authentication. An alias can keep your email address private, but it can't replace these recovery details.
Key point: Recovering your assets takes more than receiving one code

One minute before you sign up
Plan for
your next email, too
Getting a usable address is just the start. These three steps can determine whether you still have somewhere to receive email the next time you need to verify your account.
- Check how much time is left
- Use the actual countdown in the homepage inbox as your guide. If the address is close to expiring, renew it before requesting a code. The sender platform determines how long the code itself is valid.
- Decide whether you need ongoing forwarding
- If you'll need to log in or recover the account later, set up a long-term email address or forwarding alias before signing up. For an existing account, change the email address on the platform itself—creating a new address here won't update it.
- Save the platform's recovery details
- Store recovery codes, proof of purchase, and any details the platform requires securely. Don't share your access credentials. Email is one part of account recovery, not complete proof of ownership.
