Duration comparison · Choose by task
When public Wi-Fi asks for your email, ask three things first: How long will the confirmation take? Might you need to resend it? Will you need to hear from them later? Duration is only one factor.
Temporary inboxes don’t require login; long-term forwarding requires you to verify your regular email first. For a one-time network check, there’s no need to create a long-term address just because it lasts longer.
Go to the comparison table01 / Three options
Think of these as three ways to receive email, not three countdowns that promise the same experience.
02 / Key comparison
First ask whether you’ll need another email. Then choose a temporary inbox or a forwarding alias.
On narrow screens, scroll horizontally to view the table. “10-minute email” describes a product category, not a policy shared by all services.
| What to compare | 10-minute email category | Tmpsky 1-hour email | Long-term forwarding alias |
|---|---|---|---|
| Getting started | Usually, get a temporary address first. Check the service to see whether registration or verification is required. | Open the homepage and copy your automatically generated address. No login required. | Verify your regular email, log in and create an alias. |
| Time available | Check the actual countdown first. Whether and how you can extend it depends on the service. | New addresses currently last 3 hours. Each renewal adds 3 hours, up to 24 hours. Check the live status. | Not governed by a temporary-email countdown; availability depends on whether your account and alias remain active. |
| After expiry | Each service sets its own rules for recycling, deletion and recovery. Don’t assume an address can be recovered. | Once expired, the address and emails can’t be recovered. Changing addresses also invalidates the old one. | No temporary expiry mechanism; dashboard archives are kept for 30 days, not permanently. |
| Delivered to your regular inbox | Don’t assume messages will be forwarded. Check whether the service offers this feature. | No. Messages stay in the temporary inbox and must be viewed on the website. | Messages are forwarded to the regular email you verified at login, but your inbox may still mark them as spam. |
| Ongoing contact | Not suitable for receiving future messages. | Not suitable for bills, long-term notifications or account recovery after you leave. | Suitable for follow-up, provided you keep the alias active and save important emails yourself. |
| Best for | One-time code delivery when you have enough time and won’t need follow-up. | Confirming hotspot access, waiting for a confirmation email or resending a code. | Follow-up bills, ongoing notifications or bookings that may need further contact. |
Email expiry, portal confirmation-link expiry and Wi-Fi session length are three separate clocks. Extending your inbox won’t extend a verification code or network session. For details on data handling, see the Privacy Policy.

Each of these three common tasks has its limits. If you’re unsure, first ask whether you’ll need to receive more messages later.
A café portal sends a confirmation email. You click the link, get online and don’t use the service again after you leave.
Get an address before submitting the portal form. Whether a 10-minute service gives you enough time depends on its countdown and delivery speed. You can also use Tmpsky.
Not suitable: A temporary email can’t meet requirements for your real name, phone number or a specific email type.
See the network verification stepsThe airport network is unreliable, pages keep redirecting, and the confirmation email may take a while or need to be requested again.
Check the time remaining with Tmpsky and renew before expiry if needed. After a resend, check the latest message. Avoid repeated submissions that could leave you with several confusing codes.
Not suitable: More time doesn’t guarantee the portal will accept the address or that every message will arrive promptly.
Plan for waiting and renewalAccommodation bookings, fee adjustments or reimbursement receipts may arrive later, and you may need to follow up after leaving the network.
Verify your regular email and create an alias before sharing it with the service. Save a copy of important bills in your own inbox.
Not suitable: Don’t treat a 30-day archive as a long-term backup. Don’t rely on a deactivatable alias as the only way to recover an important account.
Log in and create an alias04 / Common misconceptions
Don’t judge the real limits by how an address looks, its countdown or the product name.
Not necessarily. A portal may check the domain, use a list of temporary email providers, validate links or apply its own risk checks. A name-like prefix won’t guarantee acceptance. If the portal explicitly rejects temporary email, use an address that meets its requirements instead of repeatedly switching addresses to get around the restriction.
No. A longer expiry simply gives you more time to receive messages and keeps the address usable for longer. Privacy also depends on how the service handles data, what you submit and how you protect your login details. Don’t leave an inbox page or credentials open on a shared computer. For sensitive uses, choose an email account you control long term.
You can’t assume that. After a temporary address expires, it can’t receive password-reset emails. Being able to read a message now doesn’t mean you’ll have access later. Temporary email isn’t suitable for banking, healthcare, primary work accounts or long-term identity recovery. Long-term forwarding also requires you to maintain access to the destination inbox and account.
