Even though I'm the developer of a "rival" service [1], it's a good news that more and more email aliases services are created. That means email alias is becoming mainstream.
For-Privacy allows you to get a unique email alias per website to hide your real email and still able to get emails from the service. You can track down who leaked your email and take action. Block all emails to this address with just one click.
Some examples and screenshots would be nice. No mention on whether this is a forwarding service or full email service. An faq would also be nice. Ie: Can I use my own domain? I’d be worried that the service stops working after some years and i lose access to everything.
