It’s hard to imagine filling up the 15GB of free storage that comes with a Gmail account, especially in the early days when it seems impossible to do so. As time goes on, you’ll find that you’re approaching the limit of how many messages you can save. Now it’s time to clean up the mess.
Suppose you set up your Gmail account back in 2007, you weren’t very organized. Whenever things become unwieldy, you try to unsubscribe from lists. But actually cleaning out nearly 15 years of emails is a daunting task.
As a result of this, it’s possible to delete Gmail messages in bulk without having to select each one one by one. Enter Label: all mail in the top search bar. Choose from a variety of options directly below the search bar, such as a specific sender, a specific time period, or messages with attachments. Unfortunately, I have a bad habit of signing up for newsletters that I don’t open, so I usually mass-delete them using the specific sender method. However, I forget that attachments can take up a ridiculous amount of storage space.
To select all messages, check the box to the left of the message list. Use the Select all conversations that match this search option if you want to remove more than 50 messages. If that doesn’t work, click the Trash icon.
Gmail keeps all trashed emails for 30 days by default, just in case you change your mind. Simply click the checkbox on the top left of your Trash folder, and then click Select all conversations that match this search to permanently delete those emails. When you are finished, click Delete forever.
