Gmail是拥有大量存储空间的电子邮件服务提供商之一。虽然这当然是一个优势，但它也是许多用户面临的最大缺点之一。由于用户可以存储千兆字节的免费数据，清理电子邮件(cleaning emails)成为次要优先事项，当用户最终用完几乎所有的免费存储空间时，他们需要处理数千封电子邮件。
虽然看到数以千计的未读和不必要的电子邮件可能会令人生畏，但清除所有内容以重新开始是非常容易和快速的。在本指南中，我们将向您展示如何删除Gmail上的所有电子邮件，以及如何设置电子邮件以自动删除旧电子邮件以及定期清理收件箱的重要性。
为什么要定期清理收件箱？(Why Should You Regularly Clean Your Inbox?)
如果您的收件箱中仍有足够的空间，您可能想知道为什么要清理它？清理您的电子邮件有很多好处。以下是主要原因：
大多数电子邮件都失去了价值(Most Emails Lose Their Value)
电子邮件的主要目的是发送和接收信息。因此，如果您收到(received an email)五年前的电子邮件，则该电子邮件中的数据很可能不再具有任何价值。
例如，如果您三年前收到前雇主的电子邮件线程，您认为该线程中的任何信息是否有价值？可能不是。这就是为什么最好只保留有价值的电子邮件并尝试删除多余的电子邮件。
人机搜索速度(Human and Computer Search Speed)
即使您通过不同项目的文件夹来组织您的电子邮件，直观地浏览 50 封电子邮件而不是 500 封电子邮件仍然更容易。即使您总是使用Gmail 的过滤选项(Gmail’s filtering option)来减少结果，它仍然无法击败更简洁、更短的列表所带来的便利。
您不仅会发现很难过滤成百上千封电子邮件，而且如果Gmail包含大量记录，它还需要更长的时间来过滤数据集。简而言之(Simply)，拥有更少的电子邮件将使您和Gmail执行更好的搜索。
本地系统性能(Local System Performance)
除了搜索速度之外，拥有许多电子邮件也会影响您的操作系统，尤其是使用本地电子邮件程序(using a local email program)。例如，您拥有的电子邮件越多，您的电子邮件程序启动并与服务器同步所需的时间就越长。
因此，您的备份将需要更长的时间。因此，即使硬盘空间相当实惠，将邮箱保持在最低限度始终是一个更好的解决方案。

Can You Delete All Emails from Gmail at Once?
Gmail is one of the email service providers that has a generous amоunt оf storage. While this is certainly an advantage, it’s also оne of the biggest drawbacks many users faсе. Aѕ users can store gigabytes of free dаta, cleaning emails becomes a lesser priority, which leaves users thousands of emails to go through when they finally use up almost all of the free storage.
While seeing thousands of unread and unnecessary emails can be intimidating, clearing everything up to start fresh is surprisingly easy and quick. In this guide, we will show you how to delete all emails on Gmail, as well as how you can set up your email to automatically delete old emails and the importance of regularly cleaning up your inbox.
Why Should You Regularly Clean Your Inbox?
If you still have enough space in your inbox, you might be wondering why you should clean it up? Cleaning up your email has numerous benefits. Here are the top reasons:
Most Emails Lose Their Value
The primary purpose of an email is to send and receive information. So, if you have received an email from five years ago, it is likely that the data from that email won’t hold any value anymore.
For example, if you had an email thread from your ex-employer three years ago, do you think that any information from that thread is valuable? Probably not. That’s why it is best only to keep emails with value and try to remove redundant ones.
Human and Computer Search Speed
Even if you organize your emails by folders on different projects, it is still easier to visually scan through 50 emails instead of 500 emails. And even if you always use Gmail’s filtering option to reduce the results, it still won’t beat the convenience of a cleaner, shorter list.
Not only will you find it hard to filter through hundreds or thousands of emails, but Gmail will also take longer to filter through a dataset if it holds a lot of records. Simply put, having fewer emails will allow you to and Gmail to perform a better search.
Local System Performance
Apart from the search speed, having many emails can also affect your operating system, especially using a local email program. For example, the more email emails you have, the longer it will take for your email program to start up and sync with the server.
As a result, your backups will take longer. So even if hard disk space is fairly affordable, keeping your mailbox at a minimum will always be a better solution.
How to Delete All Emails on Gmail
If you want to delete every email you have in your Gmail inbox, all you need is a computer, your Gmail account, and a bit of time. Then, follow the steps below to wipe out your inbox completely:
- Open your Gmail account on your browser.
- On your Gmail inbox, choose which category you want to delete. Gmail inboxes are segmented into three or four categories: Primary, Social, Updates, and Promotions. The quickest way to delete emails in Gmail is to remove them by category.
- Select the tab you want to clear by clicking on it. (In this guide, we will delete the Promotions tab.)
- On the top-left side of your screen, check the small tick box under the Search mail search bar. This will select every email on the page, which is up to 50 emails, and all selected emails will turn into a darker shade. If you have more than 50 promotional emails, doing this won’t get everything, but the next step will.
- Next, you will see a small text displayed at the top part of your screen saying, “All 50 conversations on this page are selected.” Select all x conversations in Promotions.” Click the part that says “Select all x conversations in Promotions.” This will allow you to select all the emails in your chosen category.
- Then, select the Trash icon located underneath the search bar.
- Once you’ve clicked the Trash icon, a pop-up window will appear to confirm whether you want to delete X number of emails. Select OK.
- After confirming the action, it will take some time, especially if you have thousands of emails. Once the process is complete, you will see a little confirmation pop-up on the bottom-left side of your screen. Simply refresh the page, and you will see that all your emails have been deleted.
Note: While you’ve deleted all your emails in the Promotion category, it doesn’t mean that they were removed from your Gmail account. With Gmail, once you delete an email, it’s stored in your trash folder for about 30 days. Only after this period will google permanently delete them. If you want to expedite this process and delete all your emails for good, follow the next steps below.
- Go to your Trash Folder found on the left menu navigation of your screen.
