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!
