You can set up almost anything to go into a separate folder using filters, which can be by sender, subject, or whatever. The easiest way to do so is to use an applicable message to create the filter:
- Open Gmail.
- Check the checkbox next to the email you want.
- Click More .
- Click Filter messages like these.
- Enter your filter criteria. You can use the subject or sender or phrase from the message.
- Click Create filter.
- To get them to go in a new folder, click Apply the label and select a label or create one. If you want it to just go into that folder and no longer be in your inbox, also select "Skip the inbox"
- Click Create filter.
