Have you started using the new Inbox by GMail, but have been feeling a little lost because you can't assign an email to multiple bundles. Well, guess what? You can assign an email to multiple bundles upon receipt.
I know, you are saying to yourself, this is great, but how do I do that. Here are the steps using two Bundles I created called Test 1 and Test 2. Setup the two bundles as shown in the images below.
Now when you get an email sent you you meeting this criteria, you Inbox will look like this.
If the email is already in your Done or other Bundle, you can assign multiple labels with a little bit of a workaround. Go into the Done bundle and find the email you want to assign to additional labels. Select the email and use the Move to function to add to another bundle. You will need to repeat this step for each additional bundle you want to assign.
Its important to remember, that GMail/Inbox by GMail only stores your email once, no matter how many Bundles/Labels you have assigned to it. So you don't have to worry about more space being used because the email appears in multiple bundles.
