How to Use Tempx Temporary Email: A Step-by-Step Tutorial

Temporary email is the kind of tool you want to work the first time you touch it — not after reading a manual. This tutorial walks through the whole flow with real screenshots: getting an address, using it on a signup form, receiving the verification code and reading it. Sixty seconds, start to finish.

Step 1 — Open your inbox

Go to tempx.uk/mail. A fresh inbox is generated the moment the page loads — no account, no form, not even a button to press. The address (something like brisk-quail-57@tempx.uk) is yours for as long as the inbox lives.

The Tempx inbox with a freshly generated address and an empty message list — A brand-new inbox. The address is ready; the list is waiting for its first message.

Step 2 — Copy the address

Click the copy icon next to the address (or select the text). That is the entire setup step. If you ever want a different address, New Address generates one on the spot — useful when a signup form has already seen the previous one.

Step 3 — Use it on any signup form

Paste the address wherever a site asks for email: a verification-gated download, a free trial, a forum registration, a one-time purchase discount. From the site's point of view it is a normal address — mail to it arrives over the regular email network.

Step 4 — Watch the message arrive

The inbox refreshes itself; there is nothing to reload. New messages show up as rows with the sender, subject and a preview. For this tutorial we signed up with two demo services — a welcome mail and a verification code — and both appeared within seconds:

Step 5 — Open the message and take what you need

Click a row and the message opens in the reading pane: sender, recipient, full HTML body, links and attachments, rendered like any mail client. Here we opened the verification mail — the one-time code is right there, and the button works:

A verification email open in the reading pane, showing a one-time code and a verify button — The verification mail. Copy the code or click the link — then you are done with this inbox forever.

Step 6 — Walk away

This is the step people forget to plan for with their real address: cleanup. With a temp inbox there is nothing to clean. Messages auto-delete when the inbox expires, and Delete all wipes everything immediately if you prefer. Nothing to unsubscribe from, nothing to archive, no residue for next quarter's campaign.

Prefer dark? The same app, one click of the moon icon in the header:

The same verification email open in dark mode — Dark mode, for late-night signups.

Good to know

Search and filters. The list has live search plus Unread/Attachments filters — handy once a busy signup session fills the inbox.
Want the address to last longer? A free account can hold named inboxes with longer retention, send over SMTP, and give coding agents read-only access via MCP.
Keep it one-way. Anonymous inboxes receive only — they cannot send, which keeps the domains clean enough for signups to accept them.
Not for keepsakes. Anything you might need next month (orders, account recovery) belongs on an alias or your real address, not here.

That is the entire tool. Open an inbox and follow along — your first address is already waiting.
