I prefer email over other messaging systems. Whenever my computer is on, my email client is open. I usually respond within 24 hours but sometimes it may take a day or two.

My email address is arh at gnu period org. It’s best to encrypt your message even if your message is not important. Use my PGP key to do so. Also, you should send me your public key so I can encrypt my messages to you too.

Decentralized real secure, encrypted, and private instant messaging is possible with XMPP. It’s been around since 1999 and many use it to connect with each other. My handle is alirezahayati@disroot.org and you can drop me encrypted messages by any XMPP-compatible account.

There’s other decentralized messengers as well. I also have an account on Matrix. My handle is @arh:nltrix.net and I usually check my messages. I prefer XMPP over Matrix but Matrix is also a good way for instant messaging.

I also post some posts on Mastodon social network. My handle is @arh@alirezahayati.com. Mastodon is decentralized, so for following me, you can be on any compatible server.

Some guides

Send your messages in plain text. Don’t send HTML messages. If you send me a link to your message, I won’t open it. Please don’t send files I haven’t asked for. I won’t open any file unless I’ve asked for it.

Don’t be shy to ask me a for a favor, if you need anything and feel I can do it for you, ask me. I’ll say no if I can’t do it or I just don’t want to.

You don’t need to be so polite, I follow Crocker’s rules.

I may miss your message. This happens very rarely but it happens. If you think I missed your message, don’t hesitate to send a reminder. Please reply your previous message so I know what’s this about.

If you want to comment on a post, send me the link of the post so I can understand what you’re talking about. Please note that my opinions have changed many times, and will change again in future, that happens when you’re growing up.

Don’t ask for personally identifiable data of me or anybody else.
