Blacklist Monitoring for Agencies

You look after websites for many clients, each with its own domain, plugins, email setup and often its own hosting. Nobody on your team visits every client site every day or reads every client's inbox.

So when a security vendor or spam blacklist flags a client domain, the warning appears somewhere you cannot see. A customer of your client sees a red screen in Chrome, a sales email lands in spam or an office firewall blocks the site. The client hears about it from their own customers, then calls you and asks why you did not spot it first.

By then the listing may have been live for days. Monitoring closes that gap: you get an alert the day a vendor changes its verdict, and you can tell the client what is happening before they ask.

Agency monitoring should cover two kinds of lists, because they cause different problems and are cleared through different channels.

Security vendors decide whether a website is safe to visit. BrandsDefender checks 90+ of them, through VirusTotal's engines plus Google Safe Browsing. VirusTotal is a service that collects verdicts from many security companies in one place. A flag from any one of them can show a browser warning or get the site blocked by antivirus apps and company firewalls.

Email spam blacklists decide whether a domain looks like spam. We check 20 of them, including the Spamhaus DBL, URIBL and the Abusix Domain Blocklist. A domain can be clean for browsers and still be listed here, as our guide on email reputation versus website blocklisting explains.

Every monitored domain is checked daily against both groups, and you get an email alert when a result changes from clean to flagged or back.

The Business and Enterprise plans include the features an agency needs to manage many client domains without mixing them up.

• Domain groups. Organize domains by client so each client's sites sit together.
• Group contacts. Send a group's alerts to the right person, such as the client's IT contact or your account lead.
• Team roles. Invite colleagues as Technical (alerts and cases) or Finance (billing).
• Alert digests. Choose instant alerts, or an hourly or daily digest.
• Webhooks. Receive flagged and cleared events over HTTPS in your ticketing tool, chat channel or dashboard.
• Ignore chosen vendors. Decide per account to ignore specific vendors you do not want alerts from.
• Insights to keep track of your monitored domains as the client list grows.
• Enterprise API. Enterprise adds a client API with API keys to add domains, read status and open cases from your own software.

An alert is only useful if your team knows what to do next. A simple, repeatable process keeps the response calm and fast.

1. 1Note which vendor or spam list flagged the domain, and when.
2. 2Confirm it with our free Domain Blacklist Checker (VirusTotal, Google Safe Browsing, Spamhaus DBL and URIBL) or the vendor's own lookup.
3. 3Check the site for real problems: unknown files, new admin users, outdated plugins, strange redirects or spam pages. Our guide on checking whether WordPress is hacked covers the basics.
4. 4If you find malware, phishing or spam, clean the site first, or hand it to the host or a cleanup specialist.
5. 5Once the site is clean, or if it was never compromised, open a removal case.
6. 6Tell the client what happened and what you did, then watch for the cleared alert.

Do not ask for removal while the problem is still live. Vendors usually check the site again, and a refused request can make the next one harder.

Clients want to know whether their business is at risk, what you are doing and when it will be over. Keep the message short and factual.

Explain the listing in one sentence, for example: "A security company has marked your domain as unsafe, so some visitors see a warning." Say who is affected, what you are doing and that the review time is set by the vendor, not by you or by us.

If a real problem on the site caused the flag, say so plainly and explain the fix. Honesty protects the relationship far better than a vague answer. And being able to say "we saw this the same day and had already started" makes it a very different conversation.

We monitor domains and handle delisting. When a domain is wrongly flagged, our team reviews the listing, prepares the evidence, submits the removal request through each vendor's official channel and follows up until the vendor responds. You get a confirmation when the listing is removed.

We do not clean malware, repair hacked sites or remove phishing kits. If a client domain really is serving malware, phishing or spam, we tell you what needs fixing, based on what the vendor and scans show, and wait until it is resolved before submitting. Your team, the host or a cleanup specialist does that work.

We cannot guarantee that a vendor will remove a flag, or how fast. Review times are set by each vendor and vary.

No cure, no pay. On subscription plans, a case credit is only used when the removal is confirmed. A one-time case costs €39, paid when you open it, and is refunded in full if the vendor refuses to remove the flag. If the same vendor flags the domain again within 30 days of a confirmed removal and nothing changed on your side, we resubmit at no extra charge. This does not apply if the listing was justified, if requested information was not provided or if the case was withdrawn.

Most agencies start on Business or Enterprise, depending on how many client domains they look after.

• Business: €999 per year for 10 domains and 20 case credits per year, or €99 per month for 10 domains and 2 case credits per month.
• Enterprise: €3,999 per year or €399 per month for 100 domains and 10 case credits per month, plus the client API.
• Extra domains: €49 per year each, so you can add clients without changing plans.
• Extra cases: €29 each, or 50 bulk credits for €999.
