# Whitelist a Sender or Domain in Gmail 1. Go into your account's Filters and Blocked Addresses settings through the settings button on the right of your mail, then the Settings option. 2. Scroll down until you find the Create a new filter link. It's right above the section for blocking email addresses. 3. In that new window that pops up, type the email address you want to whitelist in the From field. * To whitelist a full email address in Gmail, type something like [email protected], of course replacing the email account and domain name with the one that corresponds to what you want to whitelist. * To whitelist a domain in Gmail, just exclude the account, like @example.com. This will apply to any email address on the "example.com" domain. Tip: If you're wanting to whitelist more than one email address or domain, you don't have to repeat this step for each one. Instead, put a break between the separate accounts, such as [email protected]|[email protected]|@example2.com. If you don't want to adjust any of the other options for a more specific filter, go ahead and click the link called "Create filter with this search" 4. Place a check in the box next to Never send it to Spam. 5. Click Create a filter to save the changes. This process is particular to Gmail but something similar can be done for most other mail providers.
