Services like Gmail, Outlook.com and Yahoo! Mail block email to protect you from unwanted or malicious email such as phishing, scams and spam. In this case, they are mistaking email that you want for email that you don’t want.

If ask your email provider to unblock or whitelist an email address, email from that address will be more likely to get through. Here is an explanation of how to do that for GmailOutlook.com or Yahoo! Mail.

How to whitelist an email address with Gmail

Sign in to your account at Gmail.com and do the following.

Add the address to your contacts

Add the email address that is sending you email (eg support@onlinegroups.net) to your Gmail Contacts. Google will usually deliver email from addresses that are in your Contacts.

Mark messages as ‘Not spam’

If Gmail has marked emails you wish to whitelist as spam, tell Gmail the emails are not spam.

  1. In Gmail, navigate to the spam folder.
  2. Search for emails containing the domain you wish to whitelist (eg onlinegroups.net).
  3. Select all the emails shown.
  4. Click More and then Not spam.

Create a filter for the address

Create a filter to tell Google to whitelist email from a domain or online group.

  1. Click the cog icon in the top-right corner, and then Settings
  2. Click on Filters and then Create a new filter
  3. Either
    • enter the domain of the email you want to whitelist in the From field or
    • enter the email address of the online group you want to whitelist in the To field
  4. Click Create filter with this search
  5. In the box headed When a message arrives that matches this search select Never send it to spam
  6. Click the Create filter button

To whitelist all email from a domain, enter the domain in the From field

Tips:

  • Do not enter email addresses in both the From and To fields as Gmail will only filter in emails that meet both criteria
  • In both the From and To fields, you can enter either a specific email address or an entire domain
  • To enter multiple domains in each field separate them with OR as in “onlinegroups.net OR groups.yahoo.com”
