How do you save all email messages from a specific sender to a folder so I can delete all other emails in one mass delete?

I have 38,000 emails. I want to delete them all except ones from one particular sender.

The general method is

  1. Find all the ones you want to save, and put a label on them. Lets call that label keep.

  2. Then execute a search to find everything except the messages that have that label. the format of that search is -label:keep

  3. when the search completes go to the left side of the list and select "all" from the drop down.

  4. You will see a message at the top of the list:

    All 100 conversations on this page are selected. Select all conversations that match this search

  5. click on the 2nd half of the message to select those 38,000 messages.

  6. Now I would create a new label " tobedeleted"and assign those messages to the label. Then click archive. Now they will be hidden from your inbox.

  7. To make sure that nothing ended up in both lists you can do a search th that looks for both labels. If nothing is returned then you know there is no overlap.

  8. Then simply: search for tobedeleted, select all, click on "Select all conversations that match this search", delete.
