Apart from that - the idea of the project is just pure fire, I would love very much to have thousands of different personas for the nasty tracking huge corporations that entangled the internet.
The official cloud hosted variant currently offers unlimited *@aliasvault.net addresses. However I’ll be adding more domains as time goes on as certain companies don’t always like the idea of aliases and tend to start blacklisting.
The self-hosted variant allows you to attach as many of your own domains that you want, and then you can choose which domain you want to generate an alias with from the GUI.
The ability to connect your own private domains to the cloud hosted variant is also on the roadmap and will be added in the coming 2-3 weeks. This will allow you to move from/to different services without losing access to your email aliases.
its probably more likely they collect the info on you and associate you with the different domains with those emails (and likely without those emails, too)
email is too easy for the user to filter out spam; why bother with that vs websites that require javascript, proactively treat users like they are bots, and also serve ice cold ads? [ex cloudflare and amazon where you have to verify you are a bot _before_ trying to login; remember when websites allowed like 3 attempts before offering the bot detections / backoff protections? - now we cannot even try to login perfectly once without getting "am you a bot?" prompts - even with TOTP]
but after all is said and done - i still really do enjoy a single email per website - it is a great way to filter items (and takes 1 attack vector out of the public email part; they dont ever get my username unless they hack the server)
