Cost Of Spam And Why Use Anti-spam Filter

E-mail is now being abused. The flow of spam on the Internet is the proof. It is annoying to download hundreds of disgusting spam emails into the inbox looking for some legitimate messages. Not only you waste your valuable time to delete junk emails by hand, you also waste your money as each spam message in your inbox takes precious kilobytes of bandwidth you paid for. In addition, spam messages can contain viruses, which can infect your computer system, and hidden tracking codes, which work as soon as you click on the message and let the spammer know that your email address is valid. With all that said, it would be great to delete the messages that you don’t want to receive beforehand and launch your email client to pull down only good emails. Anti-spam software can do this for you. It helps you fight against annoying spam.



There is a wide choice of anti-spam filters available on the Internet. The common services or features they offer are:

• Whitelist and Blacklist. The decision whether an email message is spam or good is taken based on the sender’s email address. The whitelist contains “friendly” email addresses, and the blacklist contains potential spammers, or simply people you don’t want to communicate with.

• Filtering based on the message subject or content. Some words or phrases are met in spam emails more often than others. These are usually vulgar or adult words (sometimes too offending). Thus, filtering based on a keyword is rather helpful.

• Virus scanning. There is possibility that spam email contains a virus in the attachment. Certain anti-spam programs allow you block emails with various suspicious attachments.

• Automatic spam detection. Some anti-spam filters can check inbound email and delete the emails they consider as spam automatically at a regular basis.

• Email recovering. Some spam blockers provide you with the ability to move spam emails to a quarantine folder and keep them for a fixed number of days. In addition, there is the possibility to recover an email from the trash if you need it.

So, with the great features and benefits that antispam software offers, you can now easily block the majority of spam emails.

Features of Spam Filters

Spam filter’s objective is to clear your inbox from unwanted messages. This is primarily done by analyzing the received email and marking it as spam or legitimate. The analysis varies depending on the type of filter used – content-based filter, whitelist-blacklist filter, etc. Though spam filters vary in detecting spam, the important features are quite the same and true to all spam filters.

The primary feature of a spam filter is its capability to detect spam. Once a new message prompts, the filter gets alert and automatically checks if it is suspicious in nature. The checking could be based in the content, subject line, HTML code of the message, or the blacklist and whitelist embedded on the spam filter by the user. If the message is confirmed as spam it will be placed in a junk folder or deleted instantly, depending on the chosen option.

In addition, spam filters use point system. Messages coming from unknown senders are given corresponding points. This means that the higher the points the more ‘spammy’ the message is. This message is either blocked or deleted automatically depending on the scale given by the user, say 5 ‘spammy’ words or symbols in a message will cause it to be blocked (delivered in the junk folder) and 10 ‘spammy’ words or symbols will cause it to be deleted. But remember not all blocked emails are spam, some are legitimate.

If your IP or email address is included in the blacklist, your emails will not be received unless you apply for whitelisting. Another feature of a spam filter is its ability to update blacklist and whitelist. If the address is not found in either the blacklist or the whitelist, the filter checks the message. Whenever the message is confirmed as spam, the email address on which that message came from is added to the blacklist. But if the message is accepted due to further actions done by the sender, to confirm his intention, the address is added to the whitelist database.

A lot of emails contain attachments where in some cases, unlikely graphics, pictures and messages are embedded. Spam filter can also check not only the message but as well as the files attached on it.

Now that you know what a spam filter is, its features and the ease it can give, you can purchase one to maintain a clean inbox. But if your problem is about ensuring email deliverability of your legitimate message, promotional or updates, then try visiting http://www.emailreach.com/
