Gmail: using filters to delete all messages that match [closed]

How can I perform the same action on all results of a label/search in Gmail?

In Gmail, I have a bunch of messages under a label that I want to delete (basically all the "unread" messages).

I can filter for and select "unread" and then delete them, but it only applies to the first 25 items and I have hundreds I want to delete.

What I'd like to do is to apply a filter, select the matches, and delete all the matches even if they're not in the top 25.

Is there a way to do this?

Answer 1

Here is the algorithm:

1. Perform the search in your mails.
2. Go to the selection of your messages (checkbox icon with small down arrow) and choose "Select all".
3. As long as there are some other messages the GMail will prompt you with a message above your mailbox (see picture).

Just click on this message and you now can delete/move/mark as spam all these messages.
