People tell me their emails to me bounce. Gmail says I have used 15GB. I deleted lots of mail but nothing changed. What should I do?
Gmail is not receiving new emails. Could my storage be full?

When the 15GB is full Gmail can not accept new mail, and senders may see a bounce. The 15GB is shared between Gmail, Google Drive and Google Photos, so large files in Drive or Photos can be the real cause.
1. Open one.google.com/storage to see which service uses the space.
2. In Gmail search has:attachment larger:10M and delete what you do not need.
3. Empty Trash and Spam. Deleted mail still counts until it is gone from Trash.
4. Do the same for Drive (including its Trash) and Photos.
After space is free it can take some time before the storage figure updates. If you need more room, you can buy extra storage from Google.
Photos used 9GB. Cleaned it up and Gmail works again. Thank you.
