Researched by: [Capterra](https://www.capterra.com/resources/author/capterra/) Updated on July 23, 2026 [Anti-spam software](https://www.capterra.com/anti-spam-software/) allows users to detect and block malicious emails by scanning content for potential threats. These tools check the IP reputation score of an inbound email, validate the recipient's email address, confirm that the email is from the authorized host, and inspect the email's content using bayesian analysis. This helps the software assign a “spam score” to each email. Administrators can set a “spam acceptance threshold” to reject, quarantine, or flag emails. * * * For more information consult our [Anti-spam Buyers Guide](#buyers-guide-content) ## ContentCatcher Rating: 4.9 out of 5 (12 reviews) Profile: [ContentCatcher](https://www.capterra.com/p/178083/CLEARNETWORK/) Visible tabs: Overview, Features, Gallery, Integrations ### Overview tab #### What is this product about?

Such emails can be quarantined for a few days and then archived. During the storage period, the recipient has the ability to approve/recover any flagged emails. - **Report spam:** Anti-spam software allows email recipients to report an email as spam to help the software provider create a new type of filter based on an analysis of the reported spam. - **Scan outbound emails:**  Some anti-spam software with outbound scanning features can flag outgoing emails with a high spam score. They also facilitate data loss prevention by identifying insider attempts to share sensitive data externally by sending to personal email accounts. * * * ## Typical features of anti-spam software - **Spam detection:** Detects and flag spam, bots, or invalid messages and emails. - **Spam blocker:** Block IP addresses with reputation scores that fail to meet a certain threshold. - **Reporting/analytics:** View and track pertinent metrics such as number of spam emails received in a month and the number of emails reported as spam by a specific recipient. - **Quarantine:** Place spam and other potentially malicious emails in a quarantine state for a specified period of time.  - **Archiving and retention:** Define retention policy for emails based on parameters such as data type and department preference, followed by automatic deletion. * * * ## The cost of anti-spam software Most products in the market are priced on a per user, per month basis and can be divided into three pricing tiers based on their starting price. **Price ranges\*:** - $3 - $7 - $7 - $26 - $26+ _\*The pricing included is for the entry-level/lowest-priced offering found on vendor websites on August 10, 2021. These ranges correspond to the 25th, 75th, and 100th percentiles of pricing information gathered from vendor websites of sample products._ The above list summarizes pricing for the base plans of most products. An enterprise or premium product that is priced higher may include additional features such as outbound scanning, SMTP controls, SURBL/URIBL filtering, greylisting, information archiving, and white labeling. * * * ## Considerations when purchasing anti-spam software Buyers need to keep the following points in mind when purchasing anti-spam software for their business: - **Features:** In addition to blocking spam messages and emails, anti-spam software can include advanced features such as clustering, rebranding, intrusion detection alerts, live monitoring of inbound and outbound emails, email encryption, and integration with an active directory. The cost of these tools also varies based on the number of users. It's important to determine your requirements before you start searching for an anti-spam solution to ensure you're paying for the functionality you need. - **Deployment options:** As you research anti-spam software, consider the pros and cons of deploying it via the cloud versus a private server. Typically, cloud deployment takes less time to get started and can have a lower cost than on-premise deployment. This choice will also depend on your existing software infrastructure and whether it supports cloud deployment.  * * * ## Relevant anti-spam software trends - **Artificial intelligence-enhanced spam filtering:** Anti-spam tools enhanced by machine learning and artificial intelligence facilitates stronger firewall support, immediate malware detection, recognition of the spam email's source, as well as automated whitelisting and blacklisting. Vendors such as [Google](https://www.yourictmagazine.com/apps-software/467-google-s-spam-filters-to-use-artificial-intelligence-ai-to-curb-those-annoying-spam-emails.html) are making spam filters more effective using artificial neural networks to detect and block spam, and identify personal preferences in organizing inboxes. * * * **Sources** Products evaluated for the pricing calculation were taken from Capterra’s [anti-spam software directory](https://www.capterra.com/anti-spam-software/).
