When using email, the term “whitelist” is used to describe an approved list of emails you want to make sure bypass spam filters and get to your inbox. There are a number of reasons a perfectly valid email can get flagged as spam but one of the most common is when people subscribe to a mailing list and don’t remember it and flag incoming emails from that list as spam. Most spam filtering services rely on users to flag spam and then build a list of probable spam domains from that. The most common messages that inadvertently go to the spam folder are from internet marketers. You can avoid that very easily in GMail.
Here’s how you do it:
- Look for an email that you want to make sure ends up where you see it.
- Determine either the email address (which narrows the filter) or domain (broadens the filter’s results) in which you are interested (Figure 1 below).
- Click on theÂ “More Actions” button or on the “Create a Filter” link in the top of the email layout (Figure 1 below).
- On the “Create a Filter” screen, add the domain or email address to the “From:” line (See Figure 2).
- Make sure you test the filter before you save it (you can delete it later but it will cost you time).
- Use the “Next Step” button to get to the final page.
- Check the “Never send it to Spam” box (Figure 3 below).
- If you want to apply the filter to messages you have received, check the “Also apply filter to…” box.
- Click on the “Create Filter” button to save the filter
