Tools
The pieces of Sojka that are useful on their own, free to use. Paste something mail-shaped and get it read, explained, and judged — nothing you paste is stored: it is parsed in memory, rendered back to you, and discarded.
DMARC report reader
Paste or upload a DMARC aggregate report (.xml, .xml.gz, .zip) exactly as it arrived and read it as a table instead of XML.
TLS-RPT report reader
Paste or upload an SMTP TLS report (.json, .json.gz) and see which sessions failed encryption, and why.
Message source analyzer
Paste a full email source (.eml) and get the verdict a receiver would reach: SPF, DKIM verified against live DNS, alignment, DMARC, and the delivery hop's TLS.
Record explainer
Paste any DMARC, SPF, DKIM, MTA-STS, TLS-RPT or BIMI record and get it explained term by term, with validation.
SPF lookup counter
Enter a domain and see its SPF record fully expanded — every include, the 10-lookup budget it spends, and the address ranges it authorizes.
DKIM key checker
Enter a selector and domain, and the published key is fetched and judged: algorithm, key length, and whether receivers will accept it.
These are one-shot snapshots. Sojka the app does all of this continuously for your own domains — reports ingested daily, records watched every 15 minutes, a push when something breaks.
