Opinions on personalized email domains?

I’m interested in feedback on a concept.

We are researching the idea of offering personalized surname based email and web addresses. This would mean that a customer could select an email address like firstname@lastname.com, and an optional web address of firstname.lastname.com for example.

Each would forward to a customer’s usual mailbox or website, so there would be be no change to existing addresses or settings – just a new personalized address in addition.

Over 35,000 surnames are available, matching over 60% of individuals.

What do you think? Is a surname based email address and web address worth a few bucks a month? Comment here with your opinion please!
