If you find a message wrongly classified as spam, you can unmark the message. Just select the message, and click the Not Spam button that appears at the top and bottom of your current view. Unmarking a message will automatically move it to your inbox.
If you find that some senders' messages are consistently being mislabeled as spam, you can prevent this by:
- Adding their email addresses to your Contacts list. Gmail will deliver messages from members of your Contacts list to your inbox, unless they meet these criteria.
- Creating a filter so the messages are never sent to Spam.
If you're sending to Gmail users and are seeing your messages marked as spam, please review our Bulk Senders guide.
