Automatically apply labels to threads using Shortwave's built-in labels, or by setting up a filter in Gmail.
By default, when you apply a built-in labels (Travel, Calendar, Newsletters, Purchases, Finance, Social, Promotions, and Updates), Shortwave remembers that and will auto-apply the label for future messages from the same sender. You can configure each label's bundle controls from settings or click Options on the toast after labeling a thread to manage auto-apply behavior for that thread.
For custom labels or criteria, you can set up filters in Gmail to automatically apply labels which will then be synced back to Shortwave. This gives you the ability for even more automatic organization!
