Email troubleshooting · Check first, then resend

Can't receive a verification code?
Find out where it got stuck

Can't receive a verification code at your temporary email address? First check whether the address is wrong, has expired or the sender hasn't sent the message. Refreshing your inbox only checks for messages that have already arrived; it can't make the sender send another one.

This page uses your selections to offer suggestions. It doesn't read your email, access credentials or the sender's delivery records.

5-step check

Trace the message, step by step

Choose what matches your situation. If you can't tell, select “Not sure.” These results guide your troubleshooting; they aren't server test results.

Does the address on the sending page exactly match the current address on the home page?

Compare the full address, including the part before @ and the domain after it. Don't rely on the display name shown by your browser's autofill.

Is this address still valid, and have you kept using the same one?

Check the countdown on the home page. A new address is valid for 3 hours by default; the time remaining on a new address doesn't tell you whether an old one is still valid.

Did the sending page confirm that the verification code was sent?

Clicking the button doesn't mean the message was sent. Complete any on-page verification, and check for a cooldown, sending limit or failure message.

Did the sender explicitly say that this email address or domain isn't supported?

This usually means the sender has a registration rule. Not receiving an email alone doesn't prove that the domain is blocked.

Can this same current address receive real emails from other senders?

The Steam and YouTube demo emails on the home page don't count as delivery evidence. Only consider real messages sent to this address, and don't use sensitive information in a test email.

Waiting and resending

Repeated resend requests can make it harder to work out what's wrong

There's no standard delivery time that applies to every website. Sending queues, email policies and verification code expiry are controlled by each service. Follow the instructions on the sending page rather than repeatedly clicking the button.

1

Keep using your current address

Manually refresh the inbox once and check that the address is still valid. The FwdNest home page checks for new messages every 7 seconds; that's the check frequency, not a promise that a verification code will arrive within that time.

If little time remains, request a 3-hour extension before the address expires. An extension only gives you more time to receive messages; it won't speed up an email that's already on its way.

2

Resend only when the sender allows it

Check the sending page for a countdown, request limit or extra verification. Don't keep requesting codes while you're in a cooldown period, or switch repeatedly between multiple addresses.

“Sent” may only mean the request was accepted; it doesn't necessarily mean the email was delivered. If the problem continues, note the time and any messages on the page, then ask the sender to investigate.

3

Use the latest code according to the sender's rules

Some services invalidate the old code when you request another; others keep it valid. Don't assume the first code to arrive is the one to use, and don't mix up codes from different sign-up sessions.

Check the sender, purpose and request time. Enter the code only on a trusted page you opened yourself. Never share a verification code with support or anyone else, even if it has expired.

For long-term accounts, paid services or account recovery, use an email address you can access long term First, check whether a disposable email address is right for this task.

For developers and service operators

If you manage the sending system

Use records from the same send attempt to connect “submitted by the app” with “delivered to the inbox.” An empty inbox isn't proof of a bounce, and a success message on the page isn't final confirmation of delivery.

This page doesn't show simulated delivery logs or check third-party sending queues. The guidance below explains what to check; it isn't a diagnosis of this email.

Trace the message from configuration to delivery Use only records you're authorized to view
Where to check What to verify What not to assume
Environment and sending configuration Distinguish test from production. Check the sending account, queue workers, sandbox recipient restrictions and whether outbound sending is actually enabled. Success in a test environment doesn't mean the email was sent through the production channel.
Final recipient address Check the full recipient address actually submitted by the app. Look for leading or trailing spaces, cached old values, typos in the form and test code that replaces the recipient. The address shown in the interface may not be the one used by the send task.
Send task and rejection records Use the time, task ID or message ID to correlate the queue, sending service response and bounce. Check for authentication, quota, rate or recipient domain rejections. The app accepting a request doesn't mean the outbound service accepted it, let alone that the recipient received it.
Content and domain identity Check the sender domain's SPF, DKIM and DMARC configuration, and whether links, attachments or template changes triggered the sending service's content policies. Don't rule out an issue with the template or sender just because other emails arrive.
Retries and verification code logic Confirm that a retry really creates a new send task, cooldown status stays in sync, and the rules for invalidating old and new codes after a resend are consistent. A button becoming active again doesn't mean a new email was created; an old code arriving late doesn't mean it's still valid.

Record only the necessary times and error categories. Before sharing screenshots, logs or support tickets, redact verification codes, email access credentials, authentication headers and unrelated personal information.

but keep your secrets to yourself

Contact support@fwdnest.com, and tell us whether you used a temporary inbox or long-term forwarding, as well as which checks you've already tried. We can't remove domain restrictions set by third-party websites or promise to restore an address that's no longer valid.
