Temp Mail gives you a fresh, disposable email address in one tap, so you can sign up for websites, apps and free trials, receive verification codes, and keep your real email private. No registration. No personal details. Just open the app and your address is ready. WHY TEMP MAIL ● Instant address – a new disposable email the moment you open the app ● Mail in seconds – verification codes, receipts and sign-up links arrive automatically ● Your own address – choose a custom name and pick from six domains ● Full email view – read complete emails with images, formatting and working links ● Attachments – save PDFs, tickets and files straight to the Files app ● New-mail alerts – get notified when an email arrives while the app is open ● Easy clean-up – delete single emails, or swap your address for a new one anytime ● Your language – English, German, French and Spanish PERFECT FOR ● Signing up for apps, newsletters and online stores without handing over your real email ● Getting one-time passwords and verification codes ● Trying free trials and downloads that ask for an email first ● Joining Wi-Fi hotspots, forums and giveaways ● Testing sign-up forms and email flows if you build websites or apps ● Keeping your main inbox clean of marketing and spam HOW IT WORKS 1. Open Temp Mail – your disposable address is created instantly. 2. Tap Copy address and paste it into any sign-up form. 3. Open the Inbox – new mail appears automatically, or tap Refresh. 4. Want a different address? Tap the change button for a new random one, or the pencil to choose your own name and domain. PRIVATE BY DESIGN ● No sign-up and no password – we never ask for your real email, name or phone number ● Each address is locked to your device with its own secret key, so only you can read its inbox ● Addresses you stop using are removed after 30 days, together with their mail – if someone later picks the same address, they can never see your old emails ● Each inbox keeps your newest 50 emails, so it never fills up ● Sending is turned off, so addresses can't be used for spam Good to know: temporary addresses are best for sign-ups and one-off codes. For accounts you want to keep for years, such as banking or work, use your permanent email. GO PREMIUM Temp Mail is free to use with ads and includes one address. Premium gives you more: ● No ads – no banners and no videos ● Up to 5 addresses at once – keep separate inboxes for shopping, apps and trials, and switch in a tap ● Addresses that last – kept for as long as you're subscribed, instead of expiring after 30 days unused Plans: ● 7-Day Access – Premium for 7 days, renews every 7 days ● Monthly Subscription – Premium for 1 month, renews every month Payment is charged to your Apple ID account when you confirm the purchase.
