Postbox Services: Email Deliverability & Security Tools

ClaudeCommunityby Postbox Consultancy Services

Claude can run real email deliverability and security checks on demand. Ask the questions people actually type (about blacklists, email spam tests, link tracing) and get answers from a live check, each with a link to the full report: - "Is my IP blacklisted?" / "Am I on a blacklist?" - check any IP against 24 DNSBLs (Spamhaus ZEN, Barracuda, SpamCop and more). - "Is my domain blacklisted?" - check a domain against the domain blacklists (Spamhaus DBL, SURBL, URIBL). - "Can someone spoof my domain?" - grade spoofing / BEC exposure A-F from SPF, DKIM and DMARC. - "Why did my email go to spam?" / "Run a spam test" - a full deliverability audit (SPF, DKIM, DMARC alignment, blacklists, reverse DNS, content) on a real message you send. - "Why did this email bounce?" - analyze a raw .eml file's headers and content. - "Where does this link really go?" - trace a URL through every redirect hop to its true destination, with phishing flags. - "How old is this domain?" and "Who owns it?" - domain age and WHOIS.
