I see the problem now; however, if the aliasing tool has regex matching (and the matching pattern is hard to guess), then I believe that solves the problem of keeping spam out while enabling automatic creation, would you agree?

if you use catchall and later run into spam issues, it gets much harder to get rid of it, as you cannot turn off the catchall if you don’t even have a list of aliases to still let through.

If the forwarding/aliasing service automatically creates an alias when the first email is received, then that skirts this problem, right?

I forward those emails to an address which is random. For example: udhxhdjeiwk@example.com.

Can you elaborate on the benefit of using a random string for your secret/true inbox? Is it so that if it’s ever compromised you can just spin up a new random string as your new inbox, point all your aliases to the new one, and burn the old one?

Each alias looks like this: company_name-[eight random character/numbers]@example.com.

Same question, how do the random characters after the company name benefit you? Is it so that if you want (or need) to continue using that particular service after a data leak, then at least you can update your profile to company_name-[different set of random characters]?

This is very helpful - thanks a lot!

Makes sense. Follow-up question: Is there any particular reason why you use the email+hfu2sb5d@example.com or email+ebay@example.com as opposed to just hfu2sb5d@example.com or ebay@example.com?

If I understand correctly, the plus sign helps you see which organization has compromised your info, but the drawback of the plus sign is that a savvy spammer can figure out what your true email address is (the part before the plus sign), whereas aliases such as hfu2sb5d@example.com or ebay@example.com conceal your true email address.

Am I thinking about this correctly?

ETA I’ve also encountered services where a plus sign in the email address is disallowed, which is another downside of the plus sign approach.

Okay, I think I’m following, thanks for the detailed explanation.

Nice!

Gotcha, so then without a catch-all, is it still possible to make up something on the fly or will I need to predetermine my aliases before I give them out? I guess it’s kinda rare, but I’m thinking about the odd circumstance where I need to come up with something on the spot and I’m away from my computer.

I’ve seen this approach mentioned in other threads. Where does one configure catch-all, is that in the settings for the mail provider or the domain registrar?

Going forward, this approach checks out, but I’m also looking to unfuck my existing accounts. Beginning to think a custom domain is the way to achieve that.
