Honestly this seems really pretentious.

My last name is almost impossible. Even people who know me tend to just abbreviate it. Whenever I meet someone new who stumbles over my name. I just smile and say 'Don't worry about it, I said it wrong the first time too.' Then give the correct pronunciation. It's a good way to break the ice.

Conversely sending someone a link on how to correctly pronounce your name just screams 'I'm impossible to get along with'.

My wife changed her name on marriage at least partially because her surname (Finnish) is hard to pronounce for random people here in the UK.

(She's a doctor so she'd has to introduce herself with it on a constant basis to patients - "Hello I'm Dr. Xxxx" - Now she has a surname that is easy to pronounce and a forename people often get wrong.)
