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?
What I did was put their company in the email, sometimes with an easy to mentally create hash. I was convinced knowing who and more would help. It did, but with a twist! (One I did not expect)
I found out a few things: (90's through 00's)
Almost everybody sold those addresses. Seriously.
Political campaigns trade on them frequently. Build up, suck them dry, get more. And whales get hit HARD.
Interestingly, a filter for 5 spaces in a row got rid of a ton of spam. Curio for your thoughts right there.
Some companies freaked right out at their company name as my email. lolol They "own" that, blah, blah...
All the hassle did not get me much!
Remember, almost everyone does let those addresses slip somehow, or they flat out trade on them.
So, more addresses = more spam, and you do know who, but it also does not matter.
It was all a push, bordering on net loss.
So, I abandoned doing that and moved to a set of filters for important email sorted into buckets.
Promoting known signal works for me. And there is always SMS, Skype, other channels. Peeps can get hold of me easy enough.
Maybe I miss a little sometimes. When it happens, I am a good human about it and what comes from there is no big so far.
Good luck!
