Most of the time you wouldn’t need to bulk delete spam or empty your trash because Gmail automatically deletes them every 30 days.
However, if you’re like me, you prefer to keep your spam and trash clean, so you like to delete it all yourself. What really frustrated me was not being able to delete spam or empty trash from my mobile device. Well, since the recent update, now you can.
Navigate to the spam or trash folder in your Gmail app. Click the menu button (3 dots in the right hand corner) and select “Delete Spam” or “Empty Trash” from the list.
Wait 2-3 seconds and voila, it’s all gone.
This is a great addition to the Gmail app. If you’re not already using it, get going!
