Check a sales lead before outreach — one call verifies the email address (syntax
Check a sales lead before outreach — one call verifies the email address (syntax, MX, disposable/role/free-provider), the company's email setup (SPF/DKIM/DMARC) and its domain age, and returns a verdict: yes, risky or no, with machine-readable reasons. Free personal mailboxes skip the company checks. DNS-level only — no SMTP mailbox probe.
