🟢check_email_deliverability(domain)
Check why emails from a domain might land in spam. Looks up the domain's public DNS: SPF, DKIM (common selectors), DMARC, MX, and whether its mail servers are on major blocklists. Returns a 0-100 score and plain-English issues, worst first. Read-only: it changes nothing and sends no email. DKIM keys on custom selectors can't be found from outside, so "DKIM not found" is only a hint. Free email providers (gmail.com etc.) aren't checked. Args: domain: The domain that sends the email, e.g. "joesplumbing.com". A website URL or an email address also works; the domain is taken from it.
