## Capabilities and processing

Enter a name or paste TXT records (dig or zone file lines). A name is sent to our server, which asks a public resolver; pasted records are read in your browser.

Every TXT record at a name, grouped by purpose (SPF, DMARC, DKIM key, verification token, other), with its length and the strings it is split into. Two SPF records and strings over 255 characters are flagged.

## Example workflow

The sample domain publishes an SPF record and eight verification tokens.

## Limits and interpretation

Each tool for SPF, DMARC or verification tokens reads these records in more depth. Nothing is stored.
