The “storage almost full” notification is a common annoyance in the digital age. Our email inbox, once a simple communication tool, has become a messy archive of messages, documents, and, unfortunately, a lot of digital junk. Just like a cluttered desk slows down work, a full email inbox can compromise the receipt of important messages and reduce general performance. The solution is simpler than you might think and is rooted in a principle as traditional as it is effective: tidying up. Regularly emptying the Trash and Spam folders is the first fundamental step to maintaining an efficient, secure, and functional inbox.
This operation is not just a matter of cleanliness, but also of good management of one’s digital resources. In a context, like the Italian and European one, where digitalization is advancing rapidly, learning to manage one’s data is an essential skill. Let’s think of our email inbox like a closet: periodically it needs to be reorganized to eliminate what is no longer needed and make room for the new. This article offers a practical guide to transforming this necessity into a simple habit, combining the wisdom of tradition with the efficiency of digital innovation.
Why it is crucial to empty Trash and Spam
Keeping the Trash and Spam folders clean is not just a matter of order, but a crucial practice for several reasons. Firstly, it frees up valuable storage space. Many email services offer limited free space and, once exhausted, you risk not receiving new emails anymore. Emptying these folders allows you to recover megabytes, or even gigabytes, avoiding the need to purchase additional space. Secondly, it improves security. The Spam folder is the receptacle for phishing attempts and messages containing malware. Even though modern filters are effective, regularly deleting these emails reduces the risk of accidentally opening a malicious link. In Italy, email phishing attacks are very widespread, with 3 out of 4 Italians having experienced one.
Finally, there is an aspect often overlooked: the environmental impact. Every archived email resides on a server that constantly consumes energy. Deleting useless messages contributes, in our small way, to reducing the digital carbon footprint. According to some estimates, a single email can generate up to 4 grams of CO2. Multiplied by billions of useless messages stored on servers around the world, the impact becomes significant. A regular cleanup, therefore, not only optimizes our digital life but is also a gesture of responsibility towards the environment.
The difference between Trash and Spam: they are not the same thing
Although both folders contain emails destined for deletion, Trash and Spam have very different functions. Understanding this distinction is essential for proper email management. The Trash is the place where messages that you have decided to delete from the inbox or other folders end up. It works like the recycle bin on your computer: items remain there for a predefined period of time (usually 30 days) before being permanently deleted, offering you a window of time to recover a message deleted by mistake.
The Spam (or “Junk Email”) folder is instead managed automatically by your email provider. Here, emails that the system identifies as potentially harmful, fraudulent (phishing), or simply unsolicited advertising are filtered. This is a first line of defense for your security. It is good practice to periodically check the Spam folder to ensure that no legitimate message has been erroneously classified as such. However, its content should be deleted regularly to avoid risks and free up space.
Practical guide: how to empty the Trash

Emptying the Trash is a quick operation that can be performed on any email client or webmail. The procedures are very similar across various providers. Deleting messages from the Trash is permanent, so it is always advisable to take one last, quick look at its content before proceeding. Here are the general steps, applicable to most services.
Emptying the Trash in Gmail
In Gmail, the process is intuitive. In the menu on the left, you might need to click on More to view all labels. Find and click on the Trash entry. Once inside, you will see a list of all the emails you have deleted. At the top, a message will inform you that “Messages that have been in Trash more than 30 days will be automatically deleted”. For immediate action, click on the link Empty Trash now. A dialog box will ask for confirmation: click on OK to permanently delete all messages. If you need to free up more space on Gmail, this is one of the first actions to take.
Emptying the Trash in Outlook
Also on Outlook.com (and in the desktop application), the procedure is very similar. Look for the folder named Deleted Items in the left panel. Select it to see the contained messages. At the top of the message list, you will find a button or link labeled Empty folder. Clicking it will ask for confirmation to proceed with the permanent deletion of all content. Confirm the operation to free up the space occupied by these emails.
Emptying the Trash in Alice Mail
For users of Alice Mail (TIM Mail), the steps do not change. Access your webmail and locate the Trash folder in the side menu. Open it to view the deleted emails. Usually, at the top of the message list, there is a clearly visible option like Empty Trash. Click on this command and confirm your intention to permanently delete all items. This simple action can be of great help, especially if you find yourself with Alice Mail storage full.
Practical guide: how to delete junk mail (Spam)
Managing the Spam folder is just as important, if not more so, for security and cleanliness reasons. The messages contained here are often useless and sometimes dangerous. As with the Trash, most providers automatically delete spam after a certain period, but periodic manual intervention is always a good practice.
Deleting Spam on Gmail
To access the Spam folder on Gmail, click on More in the left menu and select Spam. Gmail will warn you that “Messages that have been in Spam more than 30 days will be automatically deleted”. To delete everything immediately, click on the link Delete all spam messages now. Confirm your choice in the pop-up window to complete the operation. Careful spam management is the first step to make the Gmail filter infallible, by correctly reporting messages that manage to get through.
Deleting Spam on Outlook
On Outlook, the dedicated folder is called Junk Email. You can find it in the folder panel on the left. Once opened, you will see all the messages that the Microsoft filter has classified as spam. At the top, just like for deleted items, you will find the Empty folder command. A click and a subsequent confirmation will be enough to completely clean out the folder and remove any potential threat.
Deleting Spam on Alice Mail
In Alice Mail, the folder to look for is named Spam or Junk Mail. Select it from the menu to view its content. In this case too, there will be a button or link, usually positioned at the top, to Empty the folder. Click it and confirm to delete all junk emails in one go. If you receive a lot of spam, it might be useful to learn how to block and report messages on Alice Mail more effectively.
Beyond cleaning: strategies for an always organized inbox
Emptying Trash and Spam is essential maintenance, but it is reactive. To keep the inbox truly efficient over time, it is useful to adopt some proactive strategies. One of the most effective is to reduce the flow of incoming emails. Take some time to unsubscribe from newsletters you no longer read. Every promotional email has, by law, an unsubscribe link at the bottom: use it. This simple gesture will drastically reduce the “noise” in your inbox.
Another powerful habit is the use of filters and rules. You can set up automatic rules to move certain emails (like social notifications or order confirmations) into specific folders, keeping the inbox clean and dedicated to important communications. Furthermore, learn to distinguish between deleting and archiving. If an email is no longer needed, delete it. If it might be useful in the future but does not require immediate action, use the Archive function. Archiving removes the message from the inbox but keeps it in a separate folder (“All Mail” on Gmail), making it retrievable via search without cluttering the main view. Learning to archive emails allows you to aim for Inbox Zero without losing valuable information.
- Locate the Trash and Spam folders
Access your email client (Gmail, Outlook, or Alice Mail) and find the Trash and Spam folders in the side menu. These areas accumulate messages that occupy precious space and need to be managed.
- Empty the Trash permanently
Open the Trash folder and click on the command ‘Empty Trash now’ or ‘Empty folder’. Confirm the operation to delete the cancelled messages forever and recover storage space.
- Delete Junk Mail
Go to the Spam or Junk Email folder. Select the option to delete all messages: you will remove potential phishing and malware threats, improving the security of your inbox.
- Unsubscribe from useless newsletters
To prevent future space issues, open promotional emails you no longer read and click on the unsubscribe link usually found at the bottom. This drastically reduces the incoming flow.
- Organize with filters and archiving
Keep the inbox tidy by setting up automatic filters for notifications and using the Archive function for messages to keep, leaving the inbox free only for urgent communications.

Frequently Asked Questions

This is a common issue caused by the fact that deleting an email usually moves it to the Trash or Deleted Items folder rather than removing it permanently. These files continue to occupy your allocated storage space until that specific folder is emptied. To resolve this and actually recover space, you must locate the Trash folder in your email client and select the option to empty it permanently.
Yes, messages filtered into the Spam or Junk Email folder occupy storage space just like regular emails in your inbox. While many providers automatically purge these messages after a set period, usually 30 days, a large volume of incoming junk mail can quickly fill your available quota. Manually emptying this folder ensures you maintain enough room for legitimate incoming communications.
The main difference lies in data retention and storage space. Deleting an email moves it to the Trash, where it will eventually be permanently removed to free up space. Archiving, conversely, simply moves the message out of your main Inbox to a general storage area, often called All Mail. Archiving cleans up your visual workspace but keeps the data searchable and does not recover any storage space.
It is recommended to check and empty these folders at least once a week. Although systems like Gmail and Outlook often have a 30-day auto-delete cycle, manual cleaning prevents storage from maxing out unexpectedly. Furthermore, frequently clearing the Spam folder reduces the security risk of accidentally interacting with malicious phishing links or malware hidden in those unsolicited messages.
Yes, digital data storage has a tangible environmental cost. Every email resides on a server that requires electricity for power and cooling 24 hours a day. By permanently deleting useless messages and emptying your Trash, you reduce the energy demand on these data centers. Estimates suggest a single email can generate up to 4 grams of CO2, so regular cleaning lowers your personal digital carbon footprint.
