Choosing the right spam filter is crucial for the cybersecurity of the organization. The enterprise spam filter reviews and ratings can give an insight into the effectiveness of a spam filter. It is prudent to conduct market research and understand the pros and cons of every spam filter before purchasing one. Cost-effectiveness is also one of the significant factors to consider.

 

Cloud Spam Filter Pricing: Choosing The Most Suitable Service For Your Organization

Knowing that the cloud spam filters can provide a massive edge over other filters, the next step in choosing the right cloud filter service is to select the correct price which suits the budget of an individual or an organization. Many cloud filter services have different cost brackets based on the number of users for whom it will be functioning. Most cloud filter services also have a free trial, which can give an idea about the functionality of a filter.

The pricing, in this case, depends on the various features the filter provides. Thus, to choose the appropriate filter, all factors mentioned above need to be considered thoroughly.

Consider Inbuilt Email Anti-spam Segregation

Many email services are equipped with the capability to separate the emails by segregating them into various lists.

  1. Whitelist: Emails from contacts that have been whitelisted are sent to the inbox. This feature, although it does help to maintain the legitimacy of emails, has a significant drawback. Emails from other addresses might wrongly be forwarded to spam if the combination of words is found as suspicious by the filter. It leads to an increased rate of false positives.
  2. Blacklisting: This option discards emails from blacklisted contacts right away.
  3. Greylist: A compromise between the whitelist and blacklist, the grey sends a ‘delivery failed’ message to the sender of the email if the email is found to be suspicious. If the email were legitimate, the sender would reattempt it. However, in most cases, spammers are not likely to resend the email again. Yet, thanks to the advancement in spamming practices, they now look for ways to overcome this filter and thus end up resending the email after delivery fails, thus defeating the purpose of the list altogether.
  4. Quarantine: Email spam filter services like that of Microsoft Office 365 isolate the suspicious email. This feature is known as quarantine. The quarantine is a junkyard for all the emails marked as spam by the user. It is an attempt to reduce false positives since the emails may be retrieved from the quarantine and marked as ‘false positive.’

 

Choosing The Best Free Email Spam Filters

Although choosing a spam filter is a good investment for an organization, budget constraints can make it challenging to install a high-end spam filtering service. In such a situation, using one of the free email spam filters can work more efficiently. Many free anti-spam filters work with the majority of email clients and have a high success rate.
