# `bird email tools validate-dmarc`

## Usage

```bash
bird email tools validate-dmarc [flags]
```

## Description

Validate a DMARC TXT record (the `v=DMARC1; p=...` string published at `_dmarc.<domain>`) and get back the parsed policy plus errors and warnings. Pass the record text in the `record` parameter; the tool parses it offline (no DNS lookup) and reports whether it is valid, what each tag resolves to, and any problems such as a missing `p` tag, an invalid percentage, or no aggregate-report address. Use this to check a record a user wrote or pasted before they publish it, or to explain what an existing record does. To fetch and check a domain's live record you must resolve DNS yourself first, then pass the result here. Public — no authentication required.

## Examples

```bash
bird email tools validate-dmarc <record>
```
