Before claiming a coupon,
know what your email address can handle.

01 / Scope

What these terms cover

These terms apply to Relayonce temporary inboxes at relayonce.com and forwarding aliases created after signing in with a real email address. Temporary inboxes don’t require an account; aliases require sign-in verification. Their access details, email records and lifecycles are managed separately.

By creating or accessing an inbox, reading email, signing in or managing aliases, you confirm that you’ve read and agree to the terms relating to those actions. If you disagree, stop using the service. Before using it, also read the Privacy Notice to understand how your data is handled.

These terms were last updated on November 6, 2026. For questions about the terms or service, email support@relayonce.com. Describe the specific issue, and don’t include sign-in codes, complete recovery links or authenticator keys in your message.

02 / Permitted use

What you can use the service for—and what you can’t

Temporary email is for messages you’re authorised to receive for a clear, short-term purpose. Using our service doesn’t replace a retailer’s sign-up requirements, offer rules or identity checks. Before entering an address, review the pre-sign-up checklist.

The same limits apply to both lists below: use must be lawful and authorised, and respect other users and third-party platforms. This is an inbox service; it doesn’t let you send messages, impersonate anyone or bypass a retailer’s safeguards.

Make sure you’re authorised to receive, view and handle messages sent to an address, and follow applicable laws and retailer rules. If a retailer doesn’t accept temporary email, use an address it approves instead of repeatedly trying to bypass its restrictions. For advice on coupon sign-ups, see our coupon sign-up guide.

03 / Temporary addresses

When the timer ends, so does access

Temporary addresses start with 3 hours of validity. Each time you renew, you get another 3 hours, up to 24 hours total. Check the dashboard result and live countdown to confirm whether a renewal worked and how much time remains. Complete any actions you need before expiry; expired links can’t restore email.

Changing your address creates a new inbox and invalidates the old address and its messages. The old address doesn’t forward to the new one. Refreshing the page or opening the same unique link on another device only gives access to the same inbox while it’s still valid; it won’t reset the timer or restore deleted content.

Retailers may reject disposable email addresses, delay verification codes or ask you to verify the same address again later. Relayonce can’t guarantee that a particular website will accept an address. Don’t use a temporary address as the sole recovery method for a payment, financial, medical or other important account, or rely on it for shipping and support messages that may arrive after it expires.

For guidance on how long addresses last and using them on another device, see Expiry and recovery. If a verification code doesn’t arrive, check the address and time remaining first, then follow our verification troubleshooting guide. Refreshing repeatedly won’t make a retailer send another message.

04 / Email forwarding

Disable, delete and sign out: three different actions

Aliases created after sign-in forward future messages to your real email address; they don’t turn a temporary inbox into a permanent one. Keep your destination inbox active. If a retailer requires ongoing address verification, make sure you still control both the alias and the inbox receiving its messages.

Disable an alias

Stops forwarding future messages. New messages received while it’s disabled are discarded; re-enabling it won’t recover them.

Delete an alias

Removes the address used to receive messages. Don’t assume you can claim the same address again after deleting it. First update any retailer accounts that still use it.

30-day archive

Lets you view recent forwarded messages and records; it isn’t a permanent backup. Deleting a record won’t remove copies already forwarded to your real inbox, and it doesn’t delete the alias.

Sign out

Ends the management session in your current browser; it doesn’t automatically disable active aliases. To stop receiving messages, explicitly disable or delete the relevant alias.

Forwarding depends on the sender, network, spam filters and the status of your destination inbox, so delivery isn’t guaranteed to be immediate or successful. Keep separate copies of important orders, payment records, invoices and support conversations. Don’t rely on the 30-day archive as your only evidence.

To keep receiving messages, start managing them with email forwarding. If you want to reduce existing promotional mail, compare when to use unsubscribing, filters or temporary addresses. Aliases can reduce direct exposure of your real address, but they won’t cancel a retailer account or subscription for you.

05 / Protecting access details

Never share credentials that open your inbox

A unique recovery link for a temporary inbox contains access credentials. Anyone with the link may be able to read or manage that inbox while it’s valid. Don’t post the full link on social media, in support-ticket screenshots, public code repositories or shared documents. After using a public device, close relevant pages and clear any saved links.

Use sign-in codes for your real email only when you initiate the sign-in. Never share them with someone claiming to be support. If you enable two-step verification, protect your authenticator key and one-time codes on your phone. Don’t share screenshots of QR codes or keys; support staff won’t ask you to send these credentials to clarify the terms.

Be careful with any action taken using your access details, especially changing addresses or deleting messages or aliases. If you suspect they’ve been exposed, stop sharing the relevant links, replace the affected temporary address or update the alias, and check the security of your retailer account and real inbox. Contacting support can’t restore messages that have already been deleted.

06 / Service and responsibility

Clear limits, no promises we can’t verify

Maintenance, network failures, delivery issues upstream, security risks or circumstances beyond our control may delay, interrupt or change the service. We don’t promise unverified uptime, fixed delivery times, retailer compatibility or account recovery results. Dashboard statuses don’t replace retailer confirmation of sign-ups, payments or offers.

We may limit requests, suspend features or disable or delete addresses and aliases if they’re used in ways that break applicable laws or these terms, or threaten service security. If security or legal requirements prevent advance notice, we may act first. If you believe this was a mistake, explain the situation by email to support; don’t include sensitive messages unrelated to your appeal.

To the extent permitted by applicable law, Relayonce doesn’t guarantee against third parties rejecting or delaying delivery, retailers deciding eligibility, or losses caused by relying on temporary addresses for long-term account recovery. This statement doesn’t exclude liability where the law prohibits it or limit any rights you have under the law.

We may update these terms to reflect changes to the service or legal requirements, and will show the new update date on this page. We’ll provide notice of significant changes as required. Before continuing to use the service, check for changes that affect how you use it. If you don’t accept them, stop using the service and first move any accounts that still need to receive messages.
