Sign in only to save addresses across devices, connect a domain you own or get Premium. WHY TMAILOR • A new address anytime: tap Random to get a fresh one. • See new mail as it arrives: messages appear without manual refresh. Turn on notifications to get an alert when new mail arrives. • Automatic cleanup: every message is deleted 24 hours after it arrives. • Reuse the same address: it doesn't expire on its own, so you can come back to it later. • Save your addresses: they're kept on your phone. Sign in to keep them in your account and use them on other devices. • Reopen the same inbox on another device: scan its QR code or open its link. • Use a domain you own: sign in and follow the in-app guide to receive email at your own domain. Premium is not required. • Available in 19 languages, with light and dark mode. GOOD FOR • Websites and apps you don't want to give your real email to • Newsletters, downloads, e-books and coupons • Free trials and one-time sign-ups • Wi-Fi sign-in pages in cafes, hotels and airports • Reducing unwanted mail and the risk of exposing your real email PREMIUM (OPTIONAL) The free version shows ads, including full-screen ads.

GOOD TO KNOW • Tmailor only receives email. You can't send, reply to or forward email. • Save anything you need within 24 hours, before the message is deleted. • If you're not signed in, your addresses are lost when you delete the app. • Don't use a temporary address for banking, important accounts or anything you may need to recover later.
