什么是 Email Posture？
Email spoofing attacks exploit misconfigured DNS records — and most domain owners don't find out until damage is done. Email Posture checks SPF, DKIM, DMARC, DNSSEC, and MTA-STS for your domain and re-checks every day. The moment something weakens or breaks, you get an email with exactly what changed and what to fix. Free instant checker on the homepage — no signup needed. Paid plans start at $12/month and include daily monitoring, alerts, and a 14-day free trial.
