RELAY / CODE TROUBLESHOOTING

Coupon signup code not arriving?
Check each step to find out what to do next.

Start with the message on the merchant’s site. A sending failure and a message marked sent that never reaches your inbox call for different checks.

01 / SENDER

The site says sending failed

Check the address format, resend cooldown and any site requirements. Refreshing your inbox won’t make the merchant send another code.

Choose the message you see to find out what to do next 02 / INBOX

It says sent, but no email arrived

First make sure the address you entered still matches your current inbox, then check its expiry. Don’t rush to switch addresses.

Check the address first, then decide how long to wait

This is a self-check guide, not a live delivery scan. We can’t access a merchant’s internal sending records, and a “sent” message doesn’t mean the receiving mail server has received the email.

CHECK / VERIFY THE ADDRESS

First, make sure
you know where the email was sent.

Compare the full address in the merchant’s signup form with the one in the homepage tool, including everything after @. Don’t check only the first few characters.

Check your current address

Check these four things before and after submitting

Does the full address match?
Copy the address again from the tool and compare it character by character with the merchant’s form. Look for missing characters, spaces before or after the address, and an old email filled in by your browser.
Did you change addresses after requesting the code?
“Get a new one” creates a new inbox and deletes the old one. Codes sent to the old address won’t appear in the new inbox. Update your address on the merchant’s site first, then request a new code according to its rules.
Is the countdown still running?
Use the live countdown in the homepage tool. Once an address expires, you can’t restore old emails, and extending it won’t recover messages that never arrived.
Is another device using the same link?
Opening the homepage on another device may not take you to the same inbox. Use the original inbox’s unique link and keep it safe like a password.

BRANCH / CHOOSE YOUR SITUATION

Select what you see.

Your selection only guides the advice here. We don’t contact the merchant, access your inbox or ask for a code or recovery link.

01Merchant’s message

Sending failedAn error, failed action or “try again later” message SentThe page clearly says the code was sent Email not supportedThe site explicitly rejects the email address or domain No clear messageNothing happens when you click, or you can’t tell what happened

02Waiting and resending

Just requested it; still in the cooldownThe merchant hasn’t allowed another send yet Waited through one cooldownStill no email, or no cooldown time was given

Follow the resend rules on the merchant’s site. A specific number of seconds is never a delivery guarantee.

03Email used this time

Relayonce temporary addressCheck for email in the homepage tool Long-term email or forwarding aliasCheck your regular inbox

Temporary inboxes and email forwarding work separately, so check them in different places.

No personal details needed. Your selection is only used to guide these steps.

Or follow these checks in order

If sending failed, address the message on the merchant’s site first. If it says sent, check the full address and expiry, then follow the resend cooldown. If the site explicitly rejects disposable email, use an email address you can access long-term instead of repeatedly trying different domains.

WAIT / WAIT AND RESEND

Stay in your current inbox;
don’t turn waiting into a cycle of switching inboxes.

Automatic checks, plus manual refresh

Your homepage inbox automatically checks for new email. You can also click “Refresh” to check the current list. Refreshing checks for email only; it won’t request another code from the merchant.

Check for new email in the tool

Follow the merchant’s resend cooldown

Repeated clicks may trigger rate limits or generate multiple codes that expire at different times. Wait until the page allows another send. If it doesn’t say when, check the merchant’s help information instead of clicking repeatedly.

After requesting a new code, follow the merchant’s instructions and use the one that’s valid. Don’t judge by arrival order alone.

Keep an eye on the expiry while you wait

If you’re going to keep waiting, check the countdown in the tool first. Before the address expires, you can extend it by 3 hours, up to 24 hours total.

Check whether you need to extend the address

The sender may queue, retry or delay an email. We can’t guarantee a delivery time, and refreshing repeatedly won’t speed up the sender.

LIMIT / WHEN TEMPORARY EMAIL MAY NOT WORK

Not every signup flow
is a good fit for a temporary address.

Separate “not received” from “can’t use.” Even if the email arrives, the code may have expired or may not work for the signup step you’re on.

View the signup checklist

The merchant explicitly rejects disposable email

Follow the merchant’s email policy and use an address you control long-term. Repeatedly switching temporary addresses may not help. This guide doesn’t provide ways to bypass domain restrictions.

The email arrived, but the code doesn’t work

Check that it’s for the right account and signup step, and that it hasn’t passed the merchant’s expiry time. Requesting another code may invalidate the old one. Don’t enter the demo email code 604917 in a real signup form.

You need support, account recovery or ongoing updates

Use an email address you can access long-term. A forwarding alias can send messages to your regular inbox, but the merchant may still reject its domain; it’s not a way around restrictions.

HELP / CONTACT THE RIGHT SUPPORT TEAM

When asking for help,
describe the issue, not your access credentials.

Contact the merchant: sending or account issues

For sending failures, rejected email addresses, invalid codes or account restrictions, contact the merchant’s official support team. They’re the ones who can check sending requests, account status and signup policies.

Include the name of the signup page, the time of the issue and your time zone.
Quote the full error message or share a screenshot with personal details hidden.
Say whether you tried resending and what cooldown the page showed.

Contact Relayonce: inbox tool issues

If your address won’t display, manual refresh keeps showing an error, or you can’t open the original inbox before it expires, let us know. We can’t check merchant accounts or guarantee recovery of expired email.

Include when the issue happened, your time zone, browser and device type.
Tell us what you clicked, what error you saw and whether you changed addresses.
Hide your address and personal details in screenshots; just tell us whether the addresses match.

Email support

Never send a code, login token or full recovery link.A recovery link contains credentials for accessing your inbox. Support doesn’t need it either. See our Privacy Policy.

NEXT / WHAT TO DO NEXT

Return to your inbox
and make sure the address is still valid.

If the address matches and hasn’t expired, keep checking for email. If it has expired or you changed inboxes, update the address on the merchant’s site before deciding whether to request another code.
