I’ve used message filters in Thunderbird a long time and couldn’t really manage without them. I’ve also created filters for GMail mailboxes. But it would be nice to be able to add filtering in GMail itself, so that emails are always sorted regardless of the client I use to read them.
- Create a subdirectory in Thunderbird or other emall client. GMail web interface doesn’t allow you to create a “real” subdirectory – creating a GMail label is not sufficient to make this work.
- Create a filter in Gmail web interface: click the down arrow in the search field, add search criteria, choose Create filter with this search.
- In the filter options, tick “Skip Inbox” and “Apply the label”, and choose the subdirectory created in step 1.
- If you want to filter all emails that already exists in Inbox, tick “Also apply filter to matching conversations.” as well.
