# Contact

Write to `hello` at this domain.

## What gets a reply

- You implemented txtfirst on a real site and something in the spec did not survive
  contact with reality. This is the most useful message you can send.
- You disagree with a requirement and can say which one and why.
- You ran the probe from [measure](/measure) on a different sample and got a
  different answer. Send the JSON.
- You are building a client that would consume this and want something changed before
  it is too late to change it.

## What does not

Sales, guest posts, link exchanges, and offers to write about this site. There is no
advertising here and there will not be.

## Reporting a problem with this site

If a page renders wrong, the markdown is the source of truth. Send the URL and its
`.md` twin and say which one is correct.

## Machine readable

```
{
  "contact": "https://txtfirst.com/contact",
  "mailbox": "hello, at this domain",
  "prefers": ["text/markdown", "text/plain"],
  "index": "https://txtfirst.com/.well-known/txtfirst.json"
}
```

An agent reading this will notice the mailbox is not written as an address. That is a
deliberate exception, and it is the one place on this site where being fully
machine-readable loses to not feeding an address harvester. If you are a person, the
first line of this page tells you what to do.
