DNS Monitoring for Agencies
Monitor client DNS records from one dashboard. Catch unauthorized changes, track propagation, and prevent DNS-related outages across your client portfolio.
Agencies live and die by uptime. When a client's website goes down or email stops delivering, the first call is always to the agency, regardless of who actually caused the problem. And more often than not, the root cause is a DNS change that nobody expected.
The challenge is structural. You manage DNS configurations across dozens or hundreds of client domains, but you rarely control the registrar account. Clients, their IT departments, or other vendors can make DNS changes at any time without notifying you. A single misguided edit to an MX record can break email for an entire organization. A deleted CNAME can take a website offline in seconds.
The Agency DNS Problem
Most agencies discover DNS issues the same way their clients do: something stops working. A website returns an error. Email bounces. A form stops submitting. By the time the agency is looped in, the client is already frustrated and looking for answers.
The problem compounds at scale. With ten clients, you might keep track of DNS configurations in your head or a spreadsheet. With fifty or a hundred, that approach breaks down completely. You need a system that watches every domain, every record, and tells you the moment something changes.
Clients change DNS without telling you
The most common source of agency DNS incidents is a well-meaning client who edits their own DNS records. They switch email providers, add a verification TXT record, or follow instructions from another vendor, and inadvertently break something your team set up months ago.
What DNS Changes Should Agencies Watch?
Not every DNS record carries the same risk. Focus your monitoring on the records that directly affect the services you manage.
A and CNAME Records
These control where the website resolves. If a client changes their A record or removes a CNAME pointing to your hosting platform, the site goes down. Monitor these on every client domain and key subdomains like www.
MX Records
Email routing depends entirely on MX records. If a client switches email providers or another vendor overwrites your MX configuration, inbound email stops flowing. This is one of the most common and most damaging DNS issues agencies face.
TXT Records (SPF, DKIM, DMARC)
Email deliverability depends on these authentication records. If they are removed or modified incorrectly, client emails start landing in spam folders. The damage is invisible until someone notices weeks later.
NS Records
Nameserver changes mean someone moved the entire DNS zone to a different provider. This is a major event that can invalidate every other record you configured. Catch it immediately.
How Agencies Approach DNS Today
| Approach | Coverage | Detection Speed | Effort Required | Reliability |
|---|---|---|---|---|
| Hope for the best | None | Hours to days | None | Poor |
| Manual spot checks | Partial | Periodic at best | High and ongoing | Inconsistent |
| Spreadsheet tracking | Snapshot only | No real-time detection | High to maintain | Degrades over time |
| DNS Monitor | All records, all domains | Minutes | Minimal after setup | Consistent and automated |
Using DNS Monitor for Client Work
DNS Monitor is built for exactly this kind of multi-domain, multi-stakeholder environment. You add your client domains, select the record types that matter, and the platform monitors them continuously. When something changes, you get an alert with the exact before-and-after values.
One Dashboard for Every Client Domain
Add all your client domains in minutes. DNS Monitor watches every record and alerts you the moment something changes.
Onboarding a New Client
Add the client domain
Enter the domain name in DNS Monitor. The platform automatically discovers existing DNS records across all record types, giving you a complete baseline snapshot.
Select records to monitor
Choose which record types matter for this client. At minimum, monitor A, CNAME, MX, and TXT records. Add NS records if you want to catch nameserver migrations.
Document the expected configuration
Use the initial snapshot as your reference point. Note which records you set up, which ones the client manages, and which ones belong to third-party services.
Configure alert routing
Set up alerts to notify the right team member. Route critical domains to senior staff. Group client domains by account manager so alerts reach the person who knows the context.
Brief the client
Let your client know that DNS changes are being monitored. This often prevents accidental changes in the first place, as clients learn to check with you before editing records.
Why Monitoring Beats Manual Checks
Manual DNS checks only catch problems you are already looking for. They require someone to remember to check, know what to look for, and compare current values against a known-good state. At scale, this is unsustainable.
Automated monitoring inverts the workflow. Instead of proactively checking, you are reactively notified. The system does the work continuously and only surfaces information when something actually changes. This frees your team to focus on client work instead of routine verification.
Use monitoring as a client differentiator
DNS monitoring is a value-add that most agencies do not offer. Including it in your service package demonstrates proactive management and justifies premium pricing. Clients appreciate knowing that someone is watching their infrastructure around the clock.
Pricing That Works for Agencies
Agency portfolios range from a handful of domains to hundreds. DNS Monitor pricing scales with your needs, so you only pay for what you use.

Handling DNS Incidents
When DNS Monitor detects a change, the alert includes the record type, old value, new value, and timestamp. This gives your team everything needed to assess the situation immediately.
- If the change was planned: Acknowledge it and update your documentation.
- If the change was unauthorized: Contact the client or registrar to revert it, using the old values from the alert as your restoration target.
- If the change is ambiguous: Investigate quickly. Sometimes a third-party vendor makes a change that is correct but unannounced.
The faster you respond to unexpected DNS changes, the less impact they have on your client's business and your agency's reputation.
Building DNS Monitoring Into Your Workflow
Make DNS monitoring part of your standard operating procedures. Add domain setup to your client onboarding checklist. Include monitoring status in your regular client reports. Use change history as an audit trail during quarterly reviews.
Over time, your DNS monitoring data becomes a valuable record of every infrastructure change across your entire client base. When a client asks what changed and when, you have the answer instantly.
Real-World Agency Scenarios
Consider the scenarios that play out at agencies every week.
A client's marketing team signs up for a new email campaign platform. The platform asks them to add a CNAME record for tracking links. The client adds the record themselves, but accidentally overwrites the existing CNAME for their www subdomain. The website goes down. The client calls you in a panic, and without monitoring, you start from scratch trying to figure out what happened.
Or a client's IT department migrates their email to a new provider. They update MX records but remove the old SPF TXT record without adding the new provider's SPF entries. Outbound email from the client's domain starts failing authentication checks. Nobody notices for two weeks until a major client reports that their invoices are landing in spam.
With DNS monitoring in place, both of these scenarios trigger an immediate alert. You know exactly what changed, when it changed, and what the previous value was. The resolution goes from hours of detective work to minutes of targeted action.
Scaling With Your Client Base
As your agency grows, DNS monitoring scales naturally. Each new client engagement starts with adding their domains to monitoring. The overhead per client is minimal: a few minutes during onboarding. But the protection is continuous and automatic from that point forward.
For agencies managing white-label services or reselling hosting, DNS monitoring also provides a layer of quality assurance. You can verify that DNS configurations remain correct even when clients or third parties make changes to records you depend on.
DNS problems are agency problems. The client does not care who changed the record. They care that their website is down and they are losing business. Proactive DNS monitoring is the simplest way to catch issues before they become incidents.
Monitor Every Client Domain From One Place
Stop discovering DNS problems after your clients do. DNS Monitor watches all your client domains and alerts you the instant something changes.
