Yahoo Mail’s Surprise Storage Slash: Why Your Deleted Emails Aren’t Freeing Up Space
If you’ve logged into your Yahoo Mail recently and noticed you’re suddenly bumping up against a storage limit, you’re not alone. In a quiet yet dramatic move, Yahoo reduced its email storage quota from a generous 1TB to just 20GB, sending shockwaves through longtime users.
Naturally, thousands of users have been scrambling to delete old messages, photos, and attachments to make space. But here’s the catch: even after deleting tens of thousands of emails, many are seeing no change in storage usage.
So what gives?

First, yes, Yahoo pulled the rug
Let’s not sugarcoat it. Yahoo’s decision to slash storage from 1TB to 20GB, without fanfare or much warning, feels like a classic “rug pull.” Many users had years’ worth of correspondence, documents, and media backed up under the assumption that 1TB meant freedom to archive.
Suddenly, the new limit is forcing some serious inbox spring cleaning. But if you’re among those who already tried a mass delete and your storage bar isn’t budging, you’re not crazy. There’s a very Yahoo reason for this.
Deleting Emails Doesn’t Instantly Free Up Space
Here’s the frustrating reality: when you delete an email in Yahoo Mail, it doesn’t truly vanish. Instead, it goes into the Trash folder, where it sits like a ghost, still haunting your storage total. Until you empty your Trash, Yahoo still counts those emails toward your 20GB cap.
Even worse? Some users have found that clicking the trash can icon doesn’t always delete everything.
“I deleted almost 40,000 emails, but my storage didn’t change at all,” said one confused user.
Another chimed in, “The trash icon was not deleting everything. I had to go in and manually select and delete all items in the Trash folder.”
That’s right. Sometimes, Yahoo’s trash-clearing tool only gets part of the job done.
💡 Here’s How to Actually Free Up Space
To make real progress toward shrinking your Yahoo Mail storage:
- Delete Unwanted Emails
Start by selecting large batches of old or unneeded emails from your Inbox, Sent, and other folders. Look for emails with attachments, those eat up the most space. - Go to the Trash Folder
This is where most people stop. Don’t. - Manually Clear the Trash
- Navigate to the Trash folder on the left sidebar.
- Click “Select All” at the top of the list.
- If more messages are present (Yahoo only loads a chunk at a time), scroll and click “Select all conversations” that appear in the trash.
- Hit “Delete” to permanently remove them.
- Confirm if prompted.
- Double-check Other Folders
Don’t forget the Spam folder or custom folders where old emails might be lurking. - Wait a Bit
Storage stats may not update immediately. Give Yahoo some time to reflect the changes, typically within a few minutes to an hour.
Pro Tips for the Storage-Panicked
- Sort by size: Use filters to find the biggest email culprits.
- Attachments = Space hogs: Consider downloading and deleting messages with large files.
- Use an email client like Thunderbird or Outlook if you want more control over bulk deletions.
Final Thoughts
Yahoo Mail’s storage reduction feels like a major step backward, and for many, a motivation to migrate to Gmail or ProtonMail. But if you’re sticking with Yahoo, understanding the quirky mechanics of deleting emails and clearing Trash can help you claw back precious space.
Just remember: “Delete” doesn’t mean “gone” until it’s out of the Trash. So empty that bin like you mean it.

What Yahoo did regarding storage amounts is wrong. It’s taking me hours to delete files. I guess it’s time to get a Gmail account. This looks like a scam to get people to buy more storage space.
Think I answered my own question. You have to select “All” & not “Priority”.
I used to be able to sort by size. Now, there are only 3 ways on the dropdown to sort… Newest. Oldest & Sender’s Name. Is there a way to sort by size I’m missing?
I have deleted thousands of emails, deleted the trash bin manually and still no reductions in amount used
very frustrating
This plan to stop incoming emails until I am able to delete enough emails is a problem. It might force me to abandon my Yahoo.Com email. It is very difficult and time consuming to find, and delete all the unwanted un-necessary emails from this account. It will be easier to save the several hundred I might need.

Like others on here, I am deleting large amounts of emails. Then deleting them in trash, but they are still there and the memory usage did not change. Very frustrating, seems very intentional on their end.
I discovered that Trash folder only can handle up to 10K of emails. That is 10’000 minus a couple, otherwise it doesn’t delete.
I found it’s much easier to send to Trash the emails from the ‘Promotions, Ads” folder I had, so after I had emptied it, I moved my Unread emails to this folder. Conveniently it transfers only exactly 10K emails, even though it says it’s transferring all. Then I would delete those, and when it gets in the Trash, I manually delete 2-3, and then system can easily delete the remaining ones from Trash. Rinse and repeat, until Unread folder is empty. Took me 24h, but I deleted about 140K emails, reduced my mailbox from 27GB to 14.4GB.

No success deleting my Trash folder. Too many in there to delete manually.
