altmails allows you to create temporary email addresses that automatically forward all emails to your personal email account. When you're done with your temporary alias, simply deactivate it and all emails sent to that alias will be blocked.
By using AltMails email addresses, you will never have to give out your personal email ever again. Instead, you can use our email addresses for every service you sign up with, making it really hard for companies and advertisers to track you online.
