Contact Josh Moller‑Mara

Note: My response time can be fairly slow, and I may forget to reply. I’m currently experimenting with my own mail server, so replies may come from another domain.

For my NYU email, you can encrypt messages to my PGP/GnuPG key, though it’s been years since someone has done this.

This is my main number for phone calls, SMS SMS (e.g. text messaging) no longer works, and Signal.

Feel free to call this number. I’m fine getting phone calls^*. I even made this number easy to remember: the local part of the number (8875788) is a palindrome.

If you want to send text messages, photos, or video chat, you can also use this number to contact me via Signal, an end-to-end encrypted messaging service.

SMS messages are discouraged. Call me or use email or Signal instead. As of 2025-10-26, I cannot either receive or send text messages on this number. I can receive them on my toll-free number, though. But please either send an email or call.

Note that I can’t receive MMS (i.e., photos or group messages) on this number at all. Use Signal if you want to send me a photo or group message (or use email or Matrix).

This is my toll-free number. Yes, calling me on this number actually works (most of the time). Only inbound SMS works here (2025-10-26: unlike my 650 number, currently), so you should generally send emails if possible.

Calling this number from a payphone does not work. It used to, but payphone surcharges increased to 50¢, then $1.00, and eventually my provider stopped accepting payphone calls completely. ¯\_(ツ)_/¯

Yup, you can contact me through the United States Postal Service. This is my main mailing address, which I can also be slow to check sometimes. But I do enjoy sending postcards and other mail, and I have a decent stack of stationery and stamps so I am able to reply to you. My handwriting is a kind of terrible cursive.

This is a good option if you want to send me physical items like handwritten notes, books, postcards, checks/money orders, even cash (technically allowed but not recommended), stickers, stamps. This is also a good option for contacting me anonymously, since in many cases you don’t need to put a return address (but I can’t write you back if you don’t!).

I know many people wouldn’t make this information public, but mail is a constitutionally protected form of communication, and I think it’s important so it’s worth some of the risk. I won’t say “please don’t send me angry letters”, you’re free to write as you choose, and in fact your writing me about a problem can help us solve it together.

For those that haven’t written too much mail before: be aware that return addresses can be spoofed or omitted. I tend to handwrite many letters, or at least put an actual handwritten signature. If you can’t verify my handwriting, another way to check if something is from me is to write me a letter with a random code and have me reply with it. I guess you could even take a $1 bill, record the serial number, send it to me, and see if I send the same bill back, since I can’t spoof money.

You can check out the Domestic Mail Manual to learn all about mail.

I’ve got a fax number as well, if you need or want that. Maybe you’re sending health documents, or maybe you’re in Japan (I hear they still use it, which honestly sounds fun). It’s my phone number minus 11. Right now it basically just goes to email.

Matrix is a good way to contact me for real-time communication.
It supports end-to-end encryption and lets you send text messages, photos, files, and group messages as well as video chat.

There are many Matrix clients for Android, iOS, and desktop. If you’re new to Matrix, I recommend checking out Element.

Note from 2024-09-23: I might be a bit slow to respond, as the matrix.org homeserver doesn’t always send notifications reliably. Though, the issue may also be on my end.
