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 you may need to check your spam folder for replies depending on your email provider (even though my emails should pass DKIM, SPF, and DMARC).

Signal is an end-to-end encrypted messaging service, and as such it’s one of the more secure ways to contact me (maybe only competing with US mail). If you want to text me, you should do it through Signal. It’s also got encrypted voice and video chat. I use it on a daily basis with a lot of my family and friends. It’s so usable that I think people may have forgotten that it’s encrypted. You can also use my non-toll-free telephone number to add me.

I can still be fairly slow to respond, and for long-form communication I tend to prefer email as it’s easier to sort and more interoperable across different clients.

This is my main number for phone calls, inbound SMS, 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. SMS support is sporadic, having been disabled in October 2025, but reenabled sometime thereafter in 2026. As of 2026-05-04, I can receive two-person text messages (not group messages or pictures), but I can’t reply, so please either send an email or call. (Note: This has to do with A2P 10DLC. My toll-free number is technically safer, but not by much.)

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.

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.
