Add the address to your contacts
Add the email address that you want to whitelist to your Gmail contacts by hovering over the sender’s name and click the “+” icon (see below):
Mark messages as ‘Not spam’
If Gmail has a newsletter as spam that you would like to go to your main inbox, you can tell Google to not mark a send as spam like this:
- Navigate to the Spam folder.
- Search for emails containing the domain you wish to whitelist (eg example.com).
- Select all the emails shown.
- Click More and then Not spam.
Create a filter for the address
This is the most complicated option but will be the most effective at ensuring you receive newsletters to your inbox:
- Click the gear icon in the top-right corner, and then See All Settings
- Click on Filters and then Create a new filter
- Enter the domain of the email you want to whitelist in the From field.
- Click Create filter with this search
- In the box headed When a message arrives that matches this search, select:
- Never send it to spam
- Categorize as Primary
- Click the “Create filter” button
