Yo so question for y'alls: what's your opinion on using custom domain (for portability) vs masked emails?
Rn I have my main emails on my personal domain, and then I have masked emails going through xxx@fastmail.com for more anonymity + segmenting (err i mean just being able to disable a certain address individually) . But watching all this reminded me that if I decided to move away from fastmail, i'm much more locked-in this way. Do y'alls use a custom domain for masked email as well? The one thing I don't like about that is that it'd be so easy to connect multiple accounts based on domain, so anonymity is probably kinda broken.
