How to white list in Cox Email

If you’re using email from Cox Communications and not receiving email from certain senders, you may want to check your spam folder and add the sender’s email address to your email account’s white list (or safelist), check blocked senders, and check your filter settings. Spam filtering is an excellent tool email providers use to help manage the unending flow of unwanted email messages sent every day. Often, this process happens silently behind the scenes, but the process can become very apparent when you don’t receive a message you need. To keep your inbox clean from unwanted emails and to help protect you against malicious messages, Cox Email has various spam-fighting methods. Here we cover the things you can do in your Cox Email account to help keep the email you want out of spam.

Mark legitimate email as Not Spam

If you’re not getting email you’re expecting in your inbox, the first thing is to check your Spam folder. If you find messages in your Spam folder that shouldn’t be there, you can mark them as not spam to help teach the Cox Webmail spam filtering software that you think that type of message is legitimate. To mark a message as not spam:

  1. Sign into your Cox Webmail account on a computer
  2. Select the WebMail Inbox
  3. Select your Spam folder
  4. Find and select the desired message
  5. Select the Not Spam button
    If you don’t see a not spam button, select the menu in the email message (three dot/line menu), then select not spam.

You should check your spam folder routinely for legitimate messages as your spam folder is emptied regularly. Marking a message as not spam won’t guarantee that future messages from that sender won’t be marked as spam, but the more you do it, the more likely it will be that the message will be delivered to your inbox. For more surefire ways, see the other options below.

Add sender to Exceptions List

In your Cox WebMail preferences, you’ll find a blocked senders list that shows the senders or domains you’ve blocked (if any) from sending you messages. In the same place, you can enter single email addresses or entire domains (e.g. that you allow to send you email. Essentially, this is Cox Mail’s version of a white list (or safelist).

  1. Sign in to your Cox Webmail account on a computer
  2. Go to the WebMail Inbox
  3. Select Preferences
  4. Under General Email Preferences, select Blocked Senders
  5. Enter the sender or domain you want to allow in the Exceptions List.
  6. Select Add
  7. Select Save

Send spam to your inbox

If you’ve tried all the above but the messages you want are still landing in your spam folder, you can modify the way Cox handles spam by changing your preferences for spam emails to have them marked as spam, but still delivered to your inbox.

  1. Sign in to your Cox Webmail account on a computer
  2. Select the gear ⚙ icon in the top right, then Settings
  3. On the left, select Inbox (if not already expanded) then select Spam settings
  4. Select the Mark as Spam and deliver to Inbox option
  5. Select Save

Recently, many very important emails end up in spam. The suggestion that declaring an email as not spam several times to increase the chances that the email will not be considered spam is ludicrous. Why is there no direct way?
Also, including sent to and received from addresses automatically in the contacts list does not work.
It’s very frustrating to have to work with an email server that basically does not work and needs constant attention.
