Not only do these emails clutter your inbox, they could also be potential security threats or malware and phishing attacks. As a business owner or the IT administrator for a business, it is your job to protect your employees as well as your business against such emails. Doing that manually, however, is almost impossible! This is where anti-spam software can help you. The software will help you build up the security you need in your email ecosystem and to streamline your email flow. To help you choose the right anti-spam software for your business, we've prepared this guide. Here we'll cover: - [What is anti-spam software?](#Whatisantispamsoftware) - [Common features of anti-spam software?](#Commonfeaturesofantispamsoftware) - [What type of buyer are you?](#Whattypeofbuyerareyou) - [Benefits of anti-spam software](#Benefitsofantispamsoftware) - [Key considerations when purchasing anti-spam software](#Keyconsiderationswhenpurchasingantispamsoftware) ## What is anti-spam software? Anti-spam software is a tool that uses a set of protocols to determine unsolicited and unwanted emails and keep them from entering your inbox. Most such tools can be customized as per your requirements, allowing you to determine what kind of messages you deem spam-worthy. _Setting filter rules in_ [SpamTitan](https://www.softwareadvice.com/secure-email-gateway/spamtitan-profile/) ## Common features of anti-spam software Subject and content filters Detect phrases that are commonly used in the subject lines and bodies of spam emails and block similar emails from reaching the inbox. White lists and black lists Manually decide whether or not you want to receive emails from a certain email address. Permitted addresses go to the white list and emails from these addresses land in your inbox; blocked addresses go to the black list and emails from them land in your spam folder. Virus detection Scan emails for viruses and malware and automatically quarantine malicious emails to the spam folder. Quarantine and email recovery Maintain quarantined emails for a period of 30 days. Quarantined emails can be manually recovered during this time, post which they are automatically deleted. Some advanced anti-spam solutions also have features such as: Grey listing Some solutions also allow grey listing emails from sources that are unknown but don't seem malicious. Grey listing is a process where the email is returned to the server it was sent from, with a request to have the email sent again. Spam servers are often too busy to respond to such requests, which helps the feature filter out spam emails. SURBL/URIBL filtering Spam URI RBL (SURBL) and Real-time URI Black List (URIBL) filtering rejects quarantining or filtering emails with malicious URLs or links to websites classified as suspicious in previous spam emails. This helps prevent phishing attacks. ## What type of buyer are you? The anti-spam needs of a boutique consulting firm with a few dozen employees would be very different from those of a large auditing firm with a few thousand employees. Hence, before selecting a solution, it is important that businesses understand what type of buyer are they. - **Small and midsize businesses:** Such business have only one anti-spamming need—keep spam emails out of employees' inboxes to prevent security attacks and wastage of time. Typically, such businesses don't host their own servers but rent clouds from third-party providers. Hence, they should go for cloud-based anti-spam software that can easily integrate with their IT ecosystem. - **Large businesses and enterprises:** Such businesses typically need to manage a heavy flow of emails in addition to keeping spams out of employees' inboxes. Typically, these buyers have their own servers or private clouds. Hence, they should go for the on-premise deployment model for anti-spam software. ## Benefits of anti-spam software Anti-spam software helps you keep your inbox clear of spam and unnecessary emails. Its benefits are as follows: - **Filter out spam from your inbox:** The software not only filters emails from specific addresses but also based on promotional subject lines and text in the email body. This helps you declutter your inbox and ensure that only the emails you want to see or those similar to the emails you are interested in land in your inbox. - **Maintain a quarantine folder:** Automatically quarantine filtered out emails and retain them in a spam folder for up to 30 days. You can recover legitimate emails that filtered out unintentionally. - **Feel no hassle over filter updates:** Most anti-spam tools automatically update the filters for new types of malware threats and spam patterns. So you don't need to bother with setting the filters manually. However, you can always choose to add filters as well as email addresses to be quarantined. ## Key considerations when purchasing anti-spam software The right anti-spam software can not only keep your inbox clutter-free but also help you dodge security breaches and attacks. However, picking a tool for your business can be a confusing process. Here are a couple of points to keep in mind: - **Don't over- or under-purchase:** When selecting your software, make sure you know what the needs of your business are and explore options accordingly. If your business doesn't need advanced features such as grey listing or SURBL/URIBL filtering, then opt for a basic solution that doesn't have them. Similarly, if your business does need these advanced features, talk to the vendor to have them included. - **Weigh deployment options thoroughly:** Your existing email ecosystem will determine the deployment option you choose for the anti-spam software and how long the deployment takes. Usually, deploying the software on a cloud is less time- and investment-consuming than doing the same on a private server. When exploring solutions, be mindful of your existing email ecosystem and ask the vendor if there could be any possible issue with the integration or deployment of the tool. _Note: The applications selected in this article are examples to show a feature in context and are not intended as endorsements or recommendations.
