I remember I made my first email address at around 2001 when I graduated from high school. Tried several email providers like Yahoo! and some local ones which half of them aren’t survived to this date.
I became obsessed with email and its technology. I registered to many email providers just to see their competing features. I learned how to send mail using telnet, wrote scripts to send mass-mail, build a tool to search keywords on google and send the result back by email, and many more.
Push mail on cellphone was also a hype, Blackberry provided email services, everyone created account on Gmail: a killer to a lot of email services. Perhaps any of you remember Hotpop or Bonbon?
I remember back then when Opera acquired Fastmail. As a (free) Fastmail user, I was excited and secure my handle at @operamail.com account in no time and just recently closed the account because they no longer provide the domain name.
Another story; I also build OneWayMail out of my curiosity. It’s a free disposable email service which has been running for nine years. It helps thousand of people using trivial services without the need to provide their real email account.
I believe email technology will bring us many benefit. End to end communication using email is irreplaceable because of its humble protocols. I also thinking about implementing email communication into IoT instead of using web services.
