I Spent a Week Setting Up an AI Email on a Single-Letter Domain

Mo MoMo MoAug 182026/08/18 264 views

I tinkered with W's newly launched AI email service over the weekend because it claims to be built on the single-letter domain w.xyz, making addresses as short as a single letter. Considering there are reportedly only 800 to 1,000 single-letter domains worldwide, I was curious whether this is just another gimmick.

I totally get that QQ Mail rejection... Last week I helped a friend set up enterprise email and got sick of this reputation thing. Whitelisting is purely manual grinding. If AI mail can't even handle this, single-letter domains are just pretty shells.
