Quttera vs unflagdomain for Website Blacklist Removal
FACTS AS PUBLISHED BY QUTTERA THREATSIGN ON SEPTEMBER 23, 2026 · SOURCES BELOW · LAST CHANGED SEPTEMBER 24, 2026
Quttera sells blacklist removal only inside its ThreatSign Premium ($299/year) and Emergency ($499/year) plans, after a malware cleanup that uses FTP, SFTP or SSH access; its FAQ states it offers no one-time malware removal. unflagdomain shows a free scan first, then for a one-time fee per domain sends a separately written request to every flagging vendor that accepts email and prepares the form-only ones, with no server access; it does not clean malware. Choose Quttera for an infected site that needs cleanup; choose unflagdomain for a clean site that is still flagged.

// quotes in the Quttera ThreatSign column are Quttera ThreatSign's own words, from the sources below. The right column is unflagdomain. unflagdomain does not clean or remove malware.
| Factor | Quttera ThreatSign | unflagdomain |
|---|---|---|
| Price | Blacklist removal is included in ThreatSign Premium at $299 per year or Emergency at $499 per year. Essential ($20 per month) states 'Blacklist Removal: Not included'. | €39 per domain, one-time — or €5 when 5 or fewer vendors flag the domain, applied automatically at checkout. No subscription, no account. |
| What the price pays for | A subscription: monitoring, malware cleanup and, after cleanup, Quttera's delisting submissions. | The dispatch: writing and sending the requests. Payable whatever the vendors then decide. |
| One-time option | No. Quttera's FAQ: 'Do you offer a one-time cleanup? No, we do not provide one-time malware removal.' Its plans are subscriptions; blacklist removal is in the two annual ones. | Yes — the only option. No plan, and no cleanup of any kind. |
| Who it is for | Owners of an infected website. Quttera cleans first and then, in its own words, 'once the site is clean we submit it for blacklist removal'. | Owners of an already-cleaned website that security vendors are still flagging. |
| Vendors covered | 'Google, Yahoo, McAfee, Norton, Yandex & 40+ other blacklists', per its plans page; the 40+ are not itemised there. | A catalog of 133 vendors (104 contacted by email, 28 by web form, 1 manual). The free scan checks the vendors whose verdicts can be queried. For every vendor that flags the domain, an email request is sent — or, for form-only vendors and Google Safe Browsing, prepared text is put on your dashboard for you to submit. |
| How removal is delivered | Quttera's team submits the requests after cleanup. Its dashboard guide asks, 'if you are using it', to add Quttera's support address as a user in Google Search Console (it calls it Google Webmaster Tools). | One separately written plain-text request per flagging email vendor, spread across one hour after payment. Sent from unflagdomain's sending address with your address as Reply-To. Form-only vendors and Google Safe Browsing become prepared cards you submit yourself. |
| Where vendor replies go | Not stated on the pages cited. | To your inbox: your address is the Reply-To, and unflagdomain never sees or stores them. A vendor system that ignores Reply-To and answers the sending address instead does not reach you — that address does not receive mail. |
| Free scanner | Yes. Its report shows Google Safe Browsing, Yandex Safe Browsing, PhishTank, URLhaus, Quttera Labs and QBMA; it does not show antivirus vendors' verdicts. | Free, no signup: the scan shows which vendors flag the domain before any payment. |
| Access required | Quttera's FAQ: 'The access is done via FTP/ SFTP and SSH', and 'A license is required for every sub-domain'. | None. No server, FTP or Search Console access is requested. |
| Malware cleanup | Yes — the core product. Quttera's FAQ: 'All our plans include unlimited malware removal'; the Essential plan adds 'Existing infections are not included'. | Not offered. unflagdomain does not scan for or remove malware; the site must be clean before the requests go out. |
| Guarantee wording | No delisting guarantee is stated. On timing, Quttera's PCRisk page: 'Reconsideration may take a few days, depending on the provider.' | Dispatch of a correctly formatted request to every flagging vendor that accepts email, within 48 hours of payment; if an address bounces, another working contact is looked for and the request re-sent when one exists. Not delisting, and not a timeline. |
| Refund | Quttera's FAQ: a full refund if 'filed within 30 days from the purchase day, and no malware removal request is submitted', or if 'we are not able to remove an infection'. | Automatic and in full when the re-scan run straight after payment finds no vendor flagging the domain, because there is nothing to send. Refunds are not tied to vendor decisions; other cases are in the refund policy. |
| What you see after paying | The ThreatSign dashboard with scan results and remediation tickets, per its dashboard guide. | Real sent, bounced and delayed counts per vendor, plus the prepared text for form-only vendors and Google Safe Browsing. |
| Outcomes published | Four case studies on its plans page; none states delisting figures. | Published per dispatch: the most recent measured one had 12 of 12 flagging vendors cleared within 15 days (one domain, measured by re-scan). Per-vendor counts accumulate in the data report. |
| Legal entity | Quttera Ltd (site footer); terms of service governed by the laws of the State of Israel; addresses in Herzliya Pituach, Israel and Sydney, Australia on its About page. | HUBtech s. r. o., Slovakia, business ID 56 882 815. Address, VAT ID and contact on every page. |
| Relationship | Quttera Labs also maintains its own website blocklist, which appears as an engine on VirusTotal. | Quttera Labs' list is one of the 133 vendors unflagdomain sends requests to when it flags a domain. |
- The site is actually infected and you want one provider to clean it, harden it and keep monitoring it.
- You want a WAF and ongoing scanning as part of the same subscription.
- You want named analysts with a stated response time (12, 8 or 4 hours by plan).
- The site is already clean and the flags are the only thing left.
- Several vendors flag you and you want one price that covers all of them, with no subscription and no server access.
- You want to see exactly which vendors flag the domain before paying, and a dashboard of what was sent and bounced afterwards.
