If you have been using Gmail frequently in the last few years, there are good possibilities that your inbox will overflow with old mails, forgotten newsletters, and heavy-size attachments. Google provides 15 GB of free storage shared across Google Drive, Gmail, and Google Photo. And, once everything fills up, you start to face problems receiving new emails. All critical messages from your clients, colleagues, or family members will not reach and simply bounce back undelivered.


Understanding how to clean up Gmail storage is a healthy practice which is needed to ensure uninterrupted communication in Gmail. The best news is that you do not require any paid subscription or third-party tools to create space. With in-built search operators of Gmail and few targeted steps, you can easily free up some gigabytes in less than a few hours.


In this guide, you will learn a few reliable methods to get your Gmail space back and ensure that your inbox operates in an uninterrupted way, from quick solutions to long-term habits.


What Is Gmail Storage?


Gmail storage is basically the free 15GB memory space that Google provides with each Google account. This storage is not just exclusive to the Gmail; it is divided across three separate yet inter-related Google services.


  • Gmail – all the emails including the ones in Drafts, Sent, and Promotions along with their attachments.
  • Google Drive – spreadsheets, documents, uploaded files, and presentations
  • Google Photos – Videos and images

This is a shared model that means that a large video that you uploaded to Google Drive in 2022 can impact your space and whether you can receive emails in 2026. This is where Google Drive storage cleanup proves to be useful while effectively managing Gmail.


To see any current usage at any given moment, go to the very bottom of the Gmail inbox; a storage indicator will become visible. Alternatively, go to one.google.com/storage and find storage section for the complete storage space break down, i.e., space utilized by each service.



Having a clear idea about how much storage each service is using is the first step toward regaining your storage.


Easy Process to Clean Up Gmail Storage: Important Methods


1. Delete the Heavy Gmail Attachments


One of the most effective and simple methods to free up space is to delete large attachments in Gmail. A single email containing a high-resolution image folder, video file, or a software package can take up a lot of space, sometimes even hundreds of megabytes. With this much space, you can receive regular emails for the entire year.


The search operators of Gmail make it quite simple to find such emails:


  • Open the Gmail and type the search filter in the search bar “has:attachment larger:10MB” to find emails heavier than 10 MB.


  • If possible, arrange the results by size and then scan the email you do not need.
  • Choose those emails and then click “Delete”.
  • For an instant impact, you can begin with the search filter “has:attachment larger:25MB” to first target the absolute largest files.

Once the files are deleted, keep in mind that the emails go to the Trash folder and they still take up space in your storage until the Trash is emptied. This is an effective method that can help you save large space without any heavy effort.


2. Empty Trash and Spam in Gmail


It is one of the most ignored steps when people research “how to clean up Gmail storage.” Once you delete the emails, they do not instantly disappear; they go to the Trash folder and stay there for 30 days before Google removes them permanently. Moreover, Spam folder gets filled up rather quickly, specifically for older accounts that have been utilized to sign up for different services over the years.


Here is how you can manually clear both folders:


  • On the left sidebar, select More to expand your complete folder list if required.


  • Go to the Trash folder and select the “Empty Trash Now” button that appears at the top of the page.


  • Go to the Spam folder and then select “Delete all SPAM messages now.”

Both actions are immediate and permanent. Consistently emptying spam and trash in Gmail, ideally once or twice every month, helps you prevent these redundant files from acquiring storage space without you even realizing it.


3. Unsubscribe From Promotional Emails and Delete Them


Newsletters and promotional emails are some of the leading contributors that inflate your inbox. A lot of users get dozens of files each week, and they live quietly in the background. The tabbed inbox of Gmail makes it quite simple to flag them in bulk.


Here is a simple approach:


  • Select the tab “Promotions” in your inbox.


  • Select the checkbox that appears at the top to choose all visible emails, and then “Select all conversations that match this search” to capture each promotional email in your account.


  • Select the option ‘Delete” to delete all emails at once.


  • You can perform a similar action in the “Social” tab, which generally contains notification emails accumulated over the years from platforms that you do not actively use.


Employing a more fine-tuned approach, utilize the search query category:promotions older_than:6m to find emails that are now older than 6 months. This will make sure that your recent receipts or deals that you might still require do not get accidentally deleted. If you want to go one step further, you can consider utilizing methods to Mass Delete Emails on Gmail to remove complete categories in bulk in a single action.


Moving forward, take some time to unsubscribe from mailing lists and newsletters that you do not need anymore. Most legit marketing emails include an Unsubscribe button visible at the bottom of the email. Fewer incoming emails imply less ongoing storage consumption over some time.



4. Search and Delete Emails by Sender or Date


Your inbox might be full of emails accumulated over the years including expired subscriptions, old jobs, or past projects that can take up a huge amount of space. The advanced search operators of Gmail enable you to target such emails with great precision:


  • before:2020/01/01 — returns all the emails that you have received before 1st January 2020.
  • older_than:3y — returns all emails that are older than three years from today.
  • from:noreply@example.com — locates all emails from a particular domain or sender. Search with filter “label: no reply.”

Once you do a search, choose all results and then delete them. In large result sets, Gmail will instruct you to choose all conversations that match the search, not just from what is visible on the screen. Always confirm this option to make sure that you perform a complete cleanup.


Once you delete the files, you can empty spam and trash in Gmail instantly to make sure that the freed storage gets reflected in your account without waiting for 30-day automatic deletion.


5. Save Email Attachments Locally, Then Delete the Emails Later On


If you get important images, documents, or files through email but you do not require the email thread itself, you can adopt a practical approach and download the attachment to your local device or an external device and then choose to delete the original email from your Gmail interface.


Use the Following Workflow:


  • Open the email that contains the attachment.
  • Select the icon Download icon on the attachment to then save it to your local device.


  • Once saved is confirmed, you can choose to delete the email thread from Gmail.


  • Then, empty the trash completely and free up your storage space instantly.

This approach is quite valuable for emails that contain a large volume of files such as design assets, project archives, or video footage that you require to retain but do not want to access through Gmail on a consistent basis.


6. Perform a Cleanup of Your Google Drive Storage


Since Google storage is shared, a Google Drive storage cleanup benefits from your Gmail capacity directly as well. Numerous users get surprised to find that their Drive holds a lot more data than their inbox, specifically if they utilize it for team collaborations, backups, or sharing of files.


Here is how you can efficiently challenge it:




  • Drive will then display storage space consumption based on service displayed visually by colors (largest to smallest).
  • Select “Clean Up Space.”
  • You can begin by cleaning up the “Trash.”


  • You can then move on to clean up emails by service. You can separately clean up “Gmail,” “Google Photos,” and “Google Drive.”


  • Click on any service.
  • Notice outdated project folders, large video files, duplicate documents, Trash, or old backups that are not needed any longer.
  • Select the ones that you want to delete.
  • Then, select “Delete.”


  • Once it is done, select the “Trash” icon appearing on the left panel and choose “Empty Trash” to free the space permanently.

One crucial point to remember: files that your senders have shared with you and the ones that you had added to “My Drive” also take up storage space. Don’t forget to review the “Shared With Me” section and delete any large files that you have added unnecessarily.


If you utilize Google Photos, notice whether images or videos in high-resolution are taking up significant space in your memory as this is often overlooked.


Tips You Can Use to Control Your Storage Space


The above sections explain one-time cleanup, which is quite crucial but developing consistent habits is important as they can keep your storage manageable in the long run. Here are a few practical tips you can use to maintain your Gmail storage:


  • Set a calendar reminder on a monthly basis to empty trash and spam in Gmail and then search for new large attachments utilizing the search filter has:attachment larger:5MB
  • Before replying or forwarding to emails containing large attachments, you can consider the recipient really requires that file or not or if a shared Google Drive link would efficiently serve the same purpose.
  • Ensure that Google Drive storage cleanup becomes a quarterly habit, especially if you consistently store media files in Drive or regularly collaborate on documents.
  • Also, if you can save the files locally, it is advisable to not download the files directly to Google Drive. This can help prevent the redundant duplication of storage space.
  • If you consistently hit your storage limits despite the cleanups, you can consider upgrading to Google One plan to get expanded storage in a cost-effective way, which is shared across all your Google account services.
  • Archive the emails you wish to keep but do not access mostly. Do not leave them in the inbox where key attachments can be difficult to track.
