Validate an email address: format check plus a live MX record lookup on its domain

InboxGuards Email Test: Email security fix plan: the exact SPF, DKIM and DMARC records to publish, with steps for your DNS host. Reads the domain's live MX, NS, SPF, DKIM and DMARC records, detects the mailbox provider and DNS host, and returns the exact records to publish in order (create / replace / keep, name, value, why): one merged SPF within the 10-lookup limit, DKIM records or the provider

Send up to 10 domain names and get back every DNS record type (A, AAAA, MX, CNAME, TXT, NS, PTR, SOA, SRV, CAA, NAPTR, DS, TLSA) plus the full WHOIS registration profile (registrar, dates, contacts, status, nameservers) for each one. URLs are accepted and automatically stripped down to the bare domain. Duplicate domains are quietly removed before processing. Results come back as one flat row per d

Reverse-resolve an IPv4 or IPv6 address to its PTR hostname(s). No PTR record returns an empty list. This is reverse DNS (PTR) — not ENS or onchain name resolution.

Validate an email address — syntax, MX/A deliverability lookup, and disposable / role-based address detection. No mailbox probing.
