What is e-mail whitelisting and how do I whitelist an e-mail address?

Whitelisting is the process of adding an email (i.e, Felix) to an approved sender list, so emails from that sender are never moved to the spam folder. Instead, when a recipient whitelists an email address, they are confirming that they know and trust the sender. This tells an email server (like Gmail) to move messages to the inbox directly. It’s that simple.

Whitelisting an e-mail sender on Gmail

First, find the email you received from the sender you want to whitelist, and start by adding the sender to your contact list. Then, create a custom Gmail filter. To do so, click on the gear icon, and select Settings. 

Select filters and blocked addresses from the navigation bar at the top of the page, then click on the create a new filter link.

Scroll down and click create a new filter for your email whitelisting notes

 Add the email address you’d like to whitelist in the “From” field, then click Create filter.

Enter the email address you'd like to whitelist in the 'From' field and then click 'Create filter'

Finally, check never send it to spam, (optional: select always mark it as important), then click create filter. From there, you will be good to go.

Check never send it to spam, and then create filter
