<h3>External services</h3>
This plugin connects to Google’s public DNS over HTTPS (DoH) API as a fallback when the server’s native DNS resolver cannot retrieve records.
Service: Google Public DNS over HTTPS 
Purpose: Resolving TXT, MX, and A DNS records for the domain being checked (SPF, DKIM, DMARC, MX lookups) when PHP’s <code>dns_get_record()</code> returns no results. 
What is sent: The domain name being queried and the DNS record type requested. 
When it is sent: Only when native DNS resolution fails for a given check. No data is sent on most servers where native DNS works correctly. 
Provider: Google LLC 
Terms of service: https://developers.google.com/terms 
Privacy policy: https://policies.google.com/privacy
No personal user data (names, emails, IP addresses of site visitors, etc.) is ever sent to this service – only the domain name being inspected.
<h3>Privacy Policy</h3>
Deliverability Inspector performs DNS lookups and optional SMTP tests using your WordPress server. No data is sent to external services except:
<ul>
<li>DNS queries to public DNS servers (standard internet protocol)</li>
<li>Optional test email via your configured SMTP server</li>
</ul>
No personal data is collected, stored, or transmitted to M Media or any third parties.
