disposable email server with an easy setup.
Whenever you sign up with your email on a website, your email address is stored and sometimes sold to advertisers. This is where you get your bulk of spam emails. Whenever a data breach happens, you also risk having your primary email address leaked and informations stolen.
Using Nortix Mail, you can create disposable email addresses that can be used to sign up to website that requires email verification. This is very useful when you just want to try out new website / services without giving away your real email address. It significantly enhances privacy, security and reduces spam. It's like running your own Gmail server.
