I am not sure whether it’s useful or not, but there is free email service where you can have a very long (again, VERY long) email address. It’s under abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijk.com domain name. Before registering, it’s better to read what it offers (because it’s so long):

• Some web forms are unable to read your email address
• Soe email software can not be configured
• People hav a hard time typing in your email address
• Companies think that your email address is fake

Read that first. But, if you want to have it, you can sign up (it’s free). You will get 25 Mb storage. But, you will have ad-supported service. That’s what it said. I haven’t tried to signup as I do not ned it.
