I still use the vanity email, but you just have to think about the phish-ability of it. I typically use [email protected] or similar for logins, instead of first@domain, or first.last@domain. It is not guessable if someone knows my name, while being easy enough for me to remember and read out on the phone or say to a person.

I do own (or have a family member buy) most of the common lastname.tld's that exist. I'm just hoping that the confusion of uncommon tld's are a good defense. Eg. I hope CS agent won't easily believe [email protected] should be [email protected] or .wiki

I do like your idea of trying to trademark the name (and I considered it too) but my name is common enough (and a word in a European language) that others have tried already, and its already in use with a handful of businesses across the world.
