GSA and Email Communication

White listing Instructions

Due to the high volume of email generated from GSA and its Connected Community, your email service provider (ESPs) might incorrectly identify the email as spam. While we do everything possible to ensure strong deliverability rates, it is sometimes necessary that you add the community email addresses to your "white list" (this tells your ESP that we are approved senders and not spam). If you stopped receiving email from GSA, this is the first and most critical step to take to ensure our email can be delivered to you.

What is a white list? A white list is a list of email addresses or domains that you want to receive emails from. By adding an address or domain to your white list, you are telling the email system not to filter email from that address or domain. Follow the appropriate instructions below for the email service provider you are using to add us to your white list and to ensure that you receive our emails.

  • Server Level
    for those using their Organization/Work address
  • Desktop Level
    includes AOL, Yahoo!, Gmail (Google), Windows Live/Hotmail, Juno, MSN, Earthlink
