Unlimited anti-spam protection is included in all packages

Key points of the Anti-Spam service

• Service Level Agreement (SLA)

  CleanTalk identifies and blocks spam bots using tests that are invisible to website visitors, providing up to 99.9705% average accuracy (false-positive rate: 0.0485%, false-negative rate: 0.0535%; rates as of November 18, 2025). This delivers SLA-level protection without the need for extra security tools — all at a simple, affordable price, as low as the cost of a cup of coffee.

• Regular updates

  We regularly release updates to the Anti-Spam plugin. Our plugins always meet new versions of CMS and we are constantly expanding supported CMS.

• Technical support

  Technical Support 24/7 to help you use the anti-spam service. If you have specific needs, you can contact our CleanTalk customer support team at any time, day or night. We strive to answer all emails within 12 hours, and most are answered in substantially less time.

• Background scoring without challenging visitors

  With CleanTalk, you can replace intrusive methods that disrupt visitor communication (such as CAPTCHA or question-answer challenges) with a more convenient, user-friendly approach where visitors aren’t distracted by solving puzzles.

• Plugins and API

  We develop over 15 in-house plugins for the top CMS platforms and offer ready-to-use libraries for many development environments, along with an API and code examples. All solutions come with the same flat pricing.

• 13+ years on the market of Anti-Spam solutions

  We have been running a trustworthy, sustainable, and innovative business for more than a decade. We help you run a spam-free operation and charge a small, fair fee that’s the same for everyone. We are debt-free, privately held, and built to last.

Pricing & Billing FAQ

• Do you have a plan designed for hosting companies?
  The Unlimited (by websites) package is ideal for hosting companies because it offers a fixed, predictable cost for the Anti-Spam service, regardless of how many sites you manage.
• Is it free?
  Short answer is no.
  Long answer - we believe in a fair and transparent model where every user pays a small fee for the service they use—rather than a freemium setup where some users end up subsidizing others. Most plans are billed annually, and the yearly cost is about the price of a single good cup of coffee. This reflects our philosophy - providing reliable, high-quality service equally to everyone.
• What is the difference between "Spam checks" and "Daily approved checks"?
  Daily approved checks – These are legitimate requests (registrations/comments/contacts) which were allowed by CleanTalk.
  Spam Checks - All requests which were identified as spam will be classed as a Spam Check. Spam Checks are unlimited on all packages.
• What happens after my trial?
  You can upgrade your account to premium package any time during the trial period. Once the trial ends your account will be suspended (all spam requests will be passed without rejections) until you choose to upgrade to the premium package.
• Can I switch to a new package before the expiration of the current?
  Yes, you can. You will be billed for the difference between the value of the new package and unused balance under the current package.
• What package to choose for WordPress Multi-User (WPMU)

  Depending on your needs we offer 3 versions of WPMU packages.

  1. Separate access keys for each website.

     This package suits you if you want to have separate anti-spam statistics, black lists and options for each website.

     1.1. Choose a tariff which corresponds to your number of websites in WPMU. Register to the service. Buy the license and add all websites to your CleanTalk Dashboard. Then you have to put each Access key in each installed plugin for every website or give them to the webmasters and they will put the keys themselves. This method is convenient for those who don’t have many websites and you want to give your clients a free anti-spam service. Furthermore, you can grant access to the added websites’ settings for your users in your CleanTalk profile using the feature “Delegation”.

     1.2. Let your users make payments for the anti-spam license. It is necessary for you to create an account and choose an appropriate tariff. This method is convenient for those who want their users to make payments for the license, to have their own anti-spam statistics, black lists and website settings.

  2. One Access key for all WPMU websites.

     You can use the same Access key for all websites. In this case anti-spam statistics, black lists and your CleanTalk settings will be identical for all websites. Register to the service and choose a one website package. Copy the Access key and put it in each CleanTalk plugin in each website.

  3. Hosting package.

     Use unlimited package to provide anti-spam service for unlimited websites. You can get access keys for all websites in your CleanTalk Dashboard.

     If you have WordPress Multisite you can use White Label Option. It allows you to add all websites to CleanTalk Dashboard automatically and all websites will have a personal Access key.
