A safe sender list, or whitelist, is a list of email addresses that a recipient has identified within their email client as contacts that they want to receive messages from. These messages more easily bypass filters in order to make it to the inbox. With increasingly stringent filtering within email clients (especially Gmail of late), it’s becoming more common that even opt-in messages get filtered out of the inbox.
Why You Should Care
Safe sender lists matter to you as an email recipient as well as an email sender.
First, you may want to review your email subscriptions and inspect your junk folder for messages that you have inadvertently missed. You should get in the habit of adding your subscribed-for email addresses to your safe sender list or address book in order to ensure they reach your inbox in the future.
Second, your sent email messages may be missing your recipient’s inbox as well. To help avoid this from happening, request for your recipients to add your sender email address to their safe sender list or address book to ensure proper delivery. You may even want to customize your request to include a link to instructions for your recipient to use based off of their email domain like Gmail, Yahoo, or Outlook for exchange users.
How to Add to a Safe Sender List
Your best bet towards ensuring appropriate delivery for your received and sent messages is to better understand email clients’ processes for categorizing incoming messages and identifying safe senders. Each email client’s methodology for adding email addresses to a safe sender or whitelist varies. However, all email clients have an address book, so utilizing the address book to ensure delivery of your sent and subscribed-for messages may be the easiest method.
