If I were stuck on a desert island with only 1 thing, it would be pretty difficult to choose between a survival expert and my trusty archive button.
Archiving lets you tidy up your inbox by moving messages from your inbox into your All Mail label, so you don’t have to delete anything. It’s like moving something into a filing cabinet for safekeeping, rather than putting it in the trash can.
Any message you’ve archived can be found by clicking the “All Mail” label on the left side of your Gmail page. You can also find a message you’ve archived by clicking on any other labels you’ve applied to it, or by searching for it by email author or keywords.
When someone responds to a message you’ve archived, the conversation containing that message will reappear in your inbox.
