Why Gmail Users Struggle with Storage

Gmail doesn't make it easy to see what's eating your space—or to bulk delete by sender. Here's why:

Gmail counts attachments toward Drive storage

Gmail and Google Drive share the same 15GB (or more) pool. Old attachments in emails count toward that limit, but Gmail doesn't show you which senders or threads use the most.

Promotions tab hides size visibility

Newsletters and promos live in the Promotions tab, so they're out of sight. Gmail doesn't show total storage per sender, so it's hard to know what to bulk delete first.

Gmail search doesn't show total sender storage

You can search by sender, but Gmail won't tell you how much space that sender uses. EmailSlim ranks senders by storage so you can bulk delete the biggest hogs first.

Gmail Bulk Delete FAQs

No. When you delete emails in Gmail (including bulk deletes via EmailSlim), they go to Gmail Trash first. They stay there for about 30 days, and you can restore them anytime. Only after 30 days in Trash does Gmail permanently delete them. EmailSlim never deletes anything without your approval—all deletions happen in your Gmail when you click delete.

Gmail Trash holds deleted messages for about 30 days. You can open Trash in Gmail and restore any message. After 30 days, Gmail automatically empties Trash and those emails are permanently deleted. When you bulk delete Gmail emails with EmailSlim, they all go to Trash first—so you have a full month to change your mind.

Yes. EmailSlim works with personal Gmail accounts and Google Workspace (Gmail for work or school). You sign in with your Google account; we use the same Gmail API and only access metadata (sender, date, size, labels). Bulk delete, storage insights, and Trash behavior are the same—deleted emails go to Trash and can be restored within about 30 days.
