Matt nailed it! I wouldn’t use this method since they all are going to forward to your main inbox and you can’t “cut off” a particular catch all address like you can with an email alias. There’s also no way to reply back through that email like you can with a proper alias system.
And is it secure to click confirmation link generated by most sites to verify your email address when signing up? Or in this way your factial email will be exposed to them ispite of using addy service?
