The majority of Internet users won't mind a few unsolicited emails now and then, but it's a pain when they miss those emails that are actually more than important than the spam. This is when you need a whitelist - a list of emails that are allowed to reach your inbox - to ensure that the most important emails are found by you.

How to whitelist emails

Spam filters implemented by your email provider will try their best to flag up the emails that are considered spam so that you don't see them, but these filters are never perfect and unwanted mail will land in your inbox. These filters will then, from time to time, flag the more important emails that you need to see as spam. Setting up a whitelist will fix this issue, by allocating the emails you want to see that have been automatically blacklisted by your email provider. 

Email Providers

Aside from Gmail and Outlook, there are several email services both online and offline that you can use. Here are the email providers and the ways you can whitelist your emails.
