When I obtained this domain, Cloudflare provided free email forwarding service which allows me to receive emails headed to @aubsebian.net from other email servers. At the time, Gmail was the only option and frankly, it was quite convenient to use both Gmail and aubsebian emails on one platform.
Allowing multiple email accounts on one host email account is called aliasing, and the setup was fairly easy. The problems besides privacy are slow synchronization/fetching (one time I had to wait over one minute) and potential useless personalized ads.
I reached out to the company where I currently work part-time, the company was started with email magazine service, but they are going to terminate it. Also, it does not even support TLS encryption, which is actually surprising to hear in 2025.
I ultimately switched to Sakura Internet (or this Japanese Wikipedia page), which is a Japanese cloud and hosting service significantly backed by the government. Interestingly, the government also began using it as its internal cloud service since 2023.
The fetching speed is like instant. By the way, I have PGP key available as well (see homepage).
