I have recently created a fastmail account at "mydomain.dev" with the goal of transitioning from Gmail to a domain that I can control in case of lockout. I would like to use aliases to help with privacy and email management.What is your strategy and reasons for creating aliases for different places you have to share your email? Or is this an attractive nuisance and not worth the mental effort of keeping track?I considered creating a few aliases, e.g. med@mydomain for medical interactions, shopping@mydomain for e.g. walmart/amazon, social@domain for twitter/fb etc, but I don't quite see how this will help me though, beyond complicating things. But I am still intuitively hesitant to share my primary alias (name@domain) with just anyone.I also can't quite see how to use it to reduce spam unless I create a unique alias for every website, which is not reasonable.So have you used email aliases/subdomains and if so how did you use it and how did it help you?
