The sophisticated app enables you to create disposable email addresses for free just by activating it. Your account simultaneously maintains multiple email addresses, which you can utilize for different purposes. As the service does not have an expiry date, the addresses can be used permanently. -------------------- - “There is a website requiring email authentication to sign up, but I don’t want to receive spam messages and newsletters…” - “Someone I’m not very close asked for my email address…” - “I need a dedicated contact email address and web form for our event” - “There are people I’m not that close but want to keep in touch” The app perfectly caters for all these needs! ------------------- The app’s features are as follows: * You can simultaneously own as many email addresses as you like! You can create additional email addresses anytime you like in just a second without making any changes to the existing address. You can either use characters of your choice for the address or have the app to generate short addresses. The app, enhanced with our proprietary technology, is also able to automatically generate easily memorable addresses. * You can communicate with the address (write new messages, reply, forward, and share)! You can send out messages from the created address and attach files. The addresses also support latest features, such as SPF, DKIM (sender authentication), encrypted delivery, etc. * Push notification is available! The app notifies the arrival of new messages even when the app is turned off. It can also send out notifications to other smartphones and PCs. You can turn the push notification off or turn it on only for specified addresses. * Permanent email addresses! The addresses you create will function permanently unless you delete them. Even if you change your mobile or delete the app, the addresses remain intact and can be restored as soon as you sign in! Although sent and received messages are automatically deleted after a month, you can permanently save them by selecting protection mode for them. * You can sync with PC and other smartphones! You can use the same address on PC and other smartphones sync messages. No difficult setup is required!
