Run multiple temporary email addresses at once
Need more than one temporary email address? This page generates multiple Gmail, Outlook, or custom-domain addresses side by side and lets you switch between their inboxes instantly — built for testers, QA teams, and anyone verifying several accounts on the same site, not just a single one-off address.
Every zephbox visitor already gets a working temporary email with no signup at all — generate one right here, right now, then generate more and switch between them above. See exact tier limits and pricing for how many you get per day.
How the mailbox switcher above actually works
Every address you generate on this page gets tracked locally in your browser — up to 10 at a time — and listed on the left of the tool above, newest first. Click any of them to switch what the inbox on the right is showing; the switch is instant because zephbox already synced that mailbox's messages in the background, it isn't re-fetching from scratch. Hit the ✕ on an entry to stop tracking it locally (this doesn't delete the mailbox itself — it just stops appearing in your list here).
Who actually needs multiple temporary email addresses at once
Most temp mail use is one-address-and-done. Running several at once tends to matter for a specific set of situations: QA teams verifying the same signup flow across several test accounts without losing track of which inbox belongs to which case, social media managers registering multiple profiles for the same client, comparing what three different SaaS trials send during onboarding, or A/B testing a signup or email sequence side by side. If that's not your situation, one address is still all you need — the switcher just stays out of the way until you generate a second one.
zephbox vs. a typical temp mail site
| Factor | zephbox | Typical temp mail site |
|---|---|---|
| Address type | Real Gmail/Outlook-style aliases or custom domains | Usually one generic disposable domain |
| Deliverability | Clears most anti-fraud domain filters | Often blocklisted by strict signup forms |
| Guest access | Works instantly, no signup at all | Some require an account for any use |
| Inbox privacy | Private to your device/account, auto-deleted on expiry | Some use public, guessable shared inboxes |
| Developer API | Real REST API — OTP extraction, webhooks, long-poll | Rare, or a scraped HTML endpoint |
Why the guest limit is lower than the free-account limit
Guest addresses are tracked only by device, which is also exactly what makes them anonymous and easy to abuse at scale — there's no account behind them to hold accountable. Keeping the guest tier at 3/day instead of 10 isn't about squeezing casual users; it's what lets zephbox keep the guest tier free and instant at all, without the abuse load that would otherwise force signup on everyone.
What a free account actually adds
Creating a free account (no card required) more than triples your daily limit to 10, and includes a one-time 7-day trial of Full Access so you can try custom domains, the developer API, and forwarding before deciding whether to pay for them. It's still $0 — the only cost is a few seconds at /register.
When Full Access is worth it
50/day plus custom domains and the developer REST API is built for people automating signups or QA testing rather than doing it by hand once in a while — see full pricing details for what's included at $2.99/mo.
