All of SiteGround's servers use custom mail filters and algorithms to identify SPAM (unsolicited email).

This, combined with SpamAssassin, ensures that most unsolicited messages will be correctly identified as SPAM.

However, if you are using a local mail client such as MS Outlook or Outlook Express for managing your mails, it is a good idea to have an additional plugin to assist you with SPAM identification and prevention.

Norton Internet Security is a great antivirus software which offers additional plugins for fighting SPAM. Once you have Norton Internet Security installed on your computer, we recommend you to use this free add-on for it. The add-on offers antispam control and confidential information blocking. It will certainly reduce the number of unsolicited messages you receive and help you manage your mail security better.
