What does the Email Deliverability and DNS checker do?

The Email Deliverability & DNS checker looks up your domain's SPF, DMARC and MX records using DNS-over-HTTPS and tells you whether they are configured correctly for mail to land in the inbox instead of spam. Missing or misconfigured records are one of the most common, most fixable reasons cold outreach and transactional email underperform.

Run it before launching any outbound campaign — a broken DMARC record can silently tank deliverability for weeks before anyone notices open rates dropping.
