Overview

If you’re not receiving our system-generated emails, please check your spam or junk mail folder. Sometimes there are some important things to consider, especially regarding your email provider and how spam is being filtered.

 There are three basic email spam filter types, and your email may have more than one depending on how you access it.  

Spam Filter Types

ISP Email Spam Filter

Web Email Provider Spam Filter

Client Spam Filter

  •  Used by ISP email services such as Comcast, Verizon, TWC, RCN, as well as other email accounts provided with an Internet service.

  • Often requires a separate login (available from your internet service provider)

  • These emails filtered by this level don’t make it to your computer or mobile device. They are filtered before they can even get to you.

  • Used by web-based email services such as Gmail, Hotmail, Yahoo.

  • These can be accessed through web email login (i.e. Gmail website) and on Mobile devices via IMAP.

  • These folders may be hidden by default, and may be called Spam or Junk.

  • Used by email client programs (Outlook, Thunderbird, Windows Mail, etc.)

  • These can be accessed on your computer or mobile device (depending on settings).

  • These may exist in addition to your ISP or Web Email filters.
