Scroll down until you find the Create a new filter link. It’s right above the section for blocking email addresses.
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 pam@removemyweight.com, 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 @removemyweight.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 support@removemyweight.com|pam@removemyweight.com|@removemyweight.com
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 >>.
Place a check in the box next to Never send it to Spam.
