What is DNS monitoring?

DNS monitoring is the practice of continuously checking your domain's DNS records for changes. When a record is modified, added, or removed, you receive an immediate alert. This catches unauthorized changes, accidental edits, and DNS hijacking before they impact your email delivery or security.

For email security specifically, monitoring SPF, DKIM, DMARC, and MX records is critical. A single unauthorized change to your MX record could redirect all your email to an attacker-controlled server. A broken SPF record could silently fail authentication for weeks.

What DNS monitoring catches

MX record hijacking

Someone changed your MX record 3 days ago. Your email has been silently routing to a server you don't control. Every message — invoices, contracts, passwords — intercepted.

Accidental SPF changes

A colleague updated the SPF record to add a new service and accidentally removed an existing include. Half your email has been failing authentication since Monday.

NS delegation changes

Your registrar account was compromised and the nameservers were changed. All your DNS records now resolve to attacker-controlled infrastructure.

Frequently asked questions

What is DNS monitoring?

Continuous checking of DNS records for changes. When SPF, DKIM, DMARC, MX, or NS records are modified, you get an instant alert — catching unauthorized or accidental changes before they cause damage.

Why do DNS records change unexpectedly?

Accidental edits, DNS migrations that drop records, compromised registrar accounts, automated changes by third-party services, or expired domains being re-registered by someone else.

How quickly are changes detected?

Sendvery checks records at regular intervals (5 minutes to 1 hour depending on your plan). Changes are detected and alerts sent within minutes of DNS propagation.

What record types are monitored?

SPF (TXT), DKIM (_domainkey TXT), DMARC (_dmarc TXT), MX, A, AAAA, NS, and CNAME records. Full DNS surveillance for email-critical records.
