Not Receiving Verification Emails? A Troubleshooting Checklist

The site says "email sent," but your temporary inbox is empty. Frustrating — but usually fixable. Work down this list in order; the most common causes are at the top.

1. Give it a minute (really)

Email is not always instant. Large senders — Microsoft, Amazon, banks — route mail through relay servers that can add a delay of one to three minutes. The sending side controls timing, not the temporary service. Wait a couple of minutes and let the inbox refresh (on tempmailfa.st it polls automatically, or hit refresh manually) before assuming something's wrong.

2. Check for a typo in the address

A surprising share of "missing" emails are simply sent to the wrong address because of a single mistyped character during sign-up. The safest habit: copy the temporary address with the copy button rather than typing it. Then double-check the field on the sign-up form before submitting.

3. Make sure the address hasn't expired

Disposable addresses are temporary by design. If you generated an address, got distracted, and came back 30 minutes later, it may have expired — and any mail sent to it is gone. Generate a fresh address and run the sign-up again, keeping the tab open this time.

4. The site may be blocking disposable domains

Some services maintain blocklists of known temporary-email domains and silently drop the message (or refuse the sign-up). If nothing arrives no matter how long you wait:

• Generate a new address — a different domain may pass.
• If it's still blocked, the site likely refuses all disposable mail; see Why Some Sites Block Disposable Email for your options.

5. Stop hammering "Resend"

Requesting five codes in a row is the fastest way to trip the sender's rate limits, which can delay or suspend delivery entirely. Send one request, wait at least a minute or two, and only then try again.

6. Verify you're on the right inbox

If you refreshed the whole page (instead of using the in-app refresh), you may have generated a new address, and the verification email is sitting in the old one. Use the inbox's own refresh control, and confirm the address shown matches the one you submitted.

7. Try a different sign-up method as a last resort

If a particular service simply won't deliver to disposable addresses, your remaining options are a permanent secondary inbox or the site's alternative sign-up (where appropriate). Temporary mail covers the throwaway half of your online life — not every site, every time.

Quick reference

Symptom	Most likely fix
Nothing after 10 seconds	Wait 1-3 minutes; sender delay
Nothing ever arrives	Domain blocked → new address
Code went to "old" inbox	You generated a new address; check the right one
Delivery got slower/stopped	You hit resend too many times
Address gone	It expired → generate a fresh one
