Updated January 2026.
If your verification email is not received when using temp mail, the cause is almost always one of these: sender delay, domain blocking, or a refresh/UX issue (especially on mobile). The good news: you can usually fix it in under five minutes.
If you need a working disposable inbox right now, start here: Anonibox temporary email generator. Generate an address, keep the tab open, and wait for the OTP/confirmation email.
90-second rescue plan (do this first)
- Wait 60–90 seconds. Many platforms queue OTP emails.
- Tap “Resend code” once. Don’t spam resend—some sites throttle.
- Keep the inbox tab open. Mobile browsers may pause background refresh.
- Generate a new address and retry the flow.
- If the platform blocks temp email, switch to an alias for that account.

Why verification emails don’t arrive on temp mail
1) The sender is delayed (queueing / throttling)
Many verification systems are intentionally conservative. If a platform sees repeated “send code” requests, suspicious traffic spikes, or heavy load, it may queue or rate-limit delivery. That can turn a 5‑second OTP into a 60‑second OTP.
2) The website blocks disposable domains
Some platforms block known disposable domains to reduce automation and abuse. The form may accept your email address, but no message ever arrives. If that happens, don’t waste time: switch strategies.
If you might keep the account (password resets, receipts, access later), use an alias instead: Email Alias (2025).
3) Your inbox expired (10-minute timer trap)
Time‑boxed inboxes are great—until the message arrives at minute 11. If you’re using strict “10‑minute” services, use a non-timer workflow or start over with a fresh address.

4) You’re watching the wrong inbox
This sounds obvious, but it’s common: you copied one address, refreshed and generated another, then waited on the old inbox. Confirm the email in the signup form matches the inbox you’re viewing.
5) Mobile background refresh is paused
On iOS/Android, browsers aggressively “sleep” background tabs. If you switch apps, the inbox can stop updating. Keep the inbox page open and active until the code arrives.
Quick diagnosis: what the website behavior tells you
If the form says “Invalid email” immediately
- Try a new temp address from Anonibox.
- If it still rejects, switch to an email alias.
If the form accepts the email but nothing arrives
- Wait 60–90 seconds.
- Resend once.
- Try a new address.
- If still nothing: assume domain blocking and use an alias.
If it arrives late (or after multiple resends)
- Stop spamming resend. Many systems throttle repeated requests.
- Use one clean resend and a fresh address if needed.

What NOT to do
- Don’t spam “Resend code” 10 times. Many platforms will throttle you or temporarily block delivery.
- Don’t use temp mail for recoverable accounts (banking, healthcare, taxes, government portals, anything you’ll need later).
- Don’t chase “bypass” tricks if a site blocks disposable domains. Use an alias or a durable inbox instead.

FAQs
How long should I wait for a verification email?
Start with 60–90 seconds. If nothing arrives, resend once. If it still fails, try a fresh address or switch to an alias if the account matters.
Why do websites block temporary emails?
To reduce automated signups and abuse. If a site blocks temp mail and you need the account, use an alias instead.
What’s the best solution if I need account recovery later?
Use an alias. It preserves privacy while remaining recoverable: Email Alias (2025).
Is temp mail safe?
Yes for low‑stakes tasks (codes, confirmations, downloads). No for sensitive or permanent accounts.
Conclusion
When your verification email is not received on temp mail, run the rescue plan:
