Email Verify

Verify email syntax and public DNS readiness with a bounded deterministic preflight. Forest checks normalized syntax, MX/address records including explicit null MX, and curated role/free/disposable-domain signals, then returns a conservative safe-to-attempt decision. It never connects to SMTP, sends mail, authenticates, stores customer mailboxes or claims that a mailbox exists.

Use when

• is this email address syntactically valid and safe to attempt
• does this email domain have public mail routing
• check an email address before trying to send to it
