To make sure you never miss an email, whitelist us by adding “email@example.com” to your address book. If you’re not sure how to do it, here are some simple instructions. It should only take a minute.
Add an email address to your Gmail white list or safe sender list
To keep important email messages out of your Gmail spam folder, you can add the sender email address to your Google Contacts and/or create a filter rule to prevent messages from specific senders going into the spam folder. If a desired email message is already in your spam folder, you can use an option to train the Gmail spam filter to not send those messages to your spam folder.
Add a Gmail Contact
When you add a sender’s email address to your contacts, it tells Google you want to receive email from that sender. This method does not guarantee messages from the desired sender won’t be sent to spam, but it’s an easy way to make it more likely the desired email will arrive in your inbox. For a more reliable method, see the instructions below for creating a filter.
On a computer (web site)
- On your computer, go to contacts.google.com
- At the top left corner, select Create contact
- Enter the contact’s information, including the sender email address
- Select Save in the bottom right corner
Mark an email as Not Spam
- On your computer, open the Gmail website
- On the left, select Spam
If you don’t see Spam, select More then find Spam
- Open the desired email message
- At the top of the page, select Not spam
The message will be moved to your inbox
If a desired email message arrives in your spam folder, you can remove it from Spam and send a signal to Gmail that you want to receive that type of email in your inbox in the future. This method doesn’t guarantee messages from that sender won’t end up in spam in the future, but it is an easy way to move the email to your inbox and train Gmail at the same time.
