The 50 most recent emails you’ve received are what Gmail by default displays in your inbox. For daily tasks where the most recent emails take priority, this approach works perfectly.
Moving to each page of old emails is not feasible, though, if you need to work on them. The good news is that Gmail lets you organise emails by when they were sent, saving you from having to flip through pages.
Additionally, this function is applicable to all inboxes, including the main inbox, dispatched items, and promotions.
Here is how to make advantage of this function.
Hover your mouse pointer over the message count in the top right corner of the inbox while it is open.
It is frequently helpful to start with the oldest email while navigating through an email list. To accomplish this, click on the email count and choose “Oldest.”
There will be a menu with the choices “Newest” and “Oldest” on it. Simply choose “Oldest” to have the emails in your inbox sorted oldest to newest.
This feature will also make it simpler for you to view older unread emails first if you have a well-organized Gmail inbox with inbox-zero achieved and receive hundreds of emails daily.
