GMAIL

Add an email address to your Gmail white list or safe sender listTo 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 ContactWhen 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.

  1. On your computer, go to contacts.google.com.
  2. At the top left corner, select Create contact.
  3. Enter the contact’s information, including the sender email address

  5. When you’re finished, tap Save
Create a filter rule to keep desired email out of spamGmail’s filters provide a lot of useful ways to manage your email and one of those ways is to set a rule to prevent email from a specific email address from going to your spam folder.

Mark an email as Not SpamIf 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.

  1. On your computer, open the Gmail website
  2. On the left, select Spam.
    If you don’t see Spam, select More
