What is multiple temp mail?

Multiple temp mail lets you run several disposable email inboxes side by side in one tab. Create 5-10 temporary email addresses, watch them all receive mail, and switch between them instantly, no signup required.

How multi-inbox works

Three simple steps to manage multiple temp mail addresses at once without losing track.

Create 10 inboxes

Tap "New email" to spin up a fresh random or custom address. Each one gets its own inbox saved on this device.

Switch instantly

Click any address in the sidebar to load its inbox immediately. No reload, no signup, no extra tabs.

Catch every code

Every inbox refreshes live, so OTPs, verification codes, and signup links arrive seconds after they're sent.

When to use multiple temp mail addresses

Running several temporary email inboxes at once is useful any time a single address is not enough.

Create multiple accounts

Register several accounts on the same site without reusing one inbox or hitting one-email-per-user limits.

Test signups and OTP flows

Generate fresh inboxes to test sign-up, verification, and password-reset emails, handy for developers and QA.

Preview and A/B test campaigns

Send a marketing email to several inboxes at once to check rendering, spam filters, and links.

Separate every signup

Keep shopping, newsletters, trials, and work signups in their own inbox instead of one cluttered mailbox.

Protect your real email

Hand out a disposable address so spam and data leaks never reach your primary inbox.

Claim trials and freebies

Grab one-time offers, downloads, and free trials without burning your main email.

Run multiple inboxes for testing and QA

Developers and QA teams open several temp mail inboxes at once to test sign-up, verification, and password-reset flows, one address per test account, without touching real mailboxes.

  1. One inbox per account

    Create a separate address for each test user so flows never collide.

  2. Trigger the emails

    Fire sign-up, OTP, and reset emails for every account in your test run.

  3. Watch them in one tab

    All inboxes refresh side by side, so a missing or slow email shows up instantly.

  4. Re-test later

    Save a token to reopen the same inbox for regression checks.

Tips for running several inboxes

A few habits keep a wall of inboxes from turning into clutter. The goal is to know at a glance which address belongs to which sign-up, and to keep only the ones you might need again.

Give each inbox a job

Create one address per task or site instead of reusing a single inbox for everything. When a confirmation arrives you will know exactly which sign-up it belongs to, and a problem with one address never affects the others.

Save the ones worth keeping

Most inboxes are throwaway, but if you might need an address again, copy its access token or sign in so it is stored to your account. You can then reopen the same inbox later from any device.

Close what you are done with

Remove an address from the list once a task is finished to stay under the limit and keep the sidebar readable. Inboxes also clear themselves automatically after about 24 hours.

Multi inbox FAQ

How many temp mail addresses can I create at once? +
You can keep 10 active inboxes open at the same time, depending on current capacity. The sidebar list scrolls, so every saved address stays within reach.
Can I check several temp mail inboxes in parallel? +
Yes. Each address keeps its own inbox cache; switching just renders what's already been received. New messages stream in automatically for every address you've created.
Will my addresses survive a page reload? +
Yes, addresses are saved on this device until you delete them. Use the Save token button if you want to reuse one on another browser.
Can I delete a temp mail address? +
Hover any address in the sidebar and click the X icon. The address is removed from your device; it will eventually expire on the server too.
Can I use multiple temp mail addresses to create multiple accounts? +
Yes. Each address has its own independent inbox, so you can register and verify several accounts on the same site at once. Some sites do block known disposable email domains, so try another domain if one is rejected.
Do I need an account to manage multiple inboxes? +
No, there is no signup. Every address is saved on this device. To reuse one later or on another browser, use the Save token button on the address.
Can I reuse a multiple temp mail inbox later? +
Yes. Save a token for any address, then reopen that exact inbox later from another browser or device. Without a token, addresses stay only on this device.
Is multiple temp mail good for testing and QA? +
Very. Open one inbox per test account to check sign-up, verification, and password-reset emails side by side, without using real mailboxes.
Multiple temp mail vs 10 minute mail, which should I use? +
Use multiple temp mail when you manage several accounts at once. Use a 10 minute mail for a single quick task you never need again.
Are my multiple inboxes private from each other? +
Yes. Each address has its own separate inbox, and a message sent to one never appears in another. Switching between them in the sidebar only changes which inbox you are viewing, not what each one receives.
What is the fastest way to create several inboxes? +
Tap 'New email' once for each address you want; every click spins up a fresh random inbox instantly with no reload. You can mix random and custom names, and each new inbox appears in the sidebar ready to use.
