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](https://en.wikipedia.org/wiki/Greylisting%5F%28email%29#:~:text=Greylisting%20is%20a%20method%20of,sender%20it%20does%20not%20recognize.) 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](/email/spam-filtering).
