EmailSlim helps you reclaim email storage fast. When your inbox says “Storage Almost Full,” it doesn’t show who’s actually taking the space. We rank your inbox by total sender storage size so you can delete the biggest clutter first. No filters or guesswork. Metadata only — we never read your email content — and you approve every deletion. Works with Gmail, Outlook, and Microsoft accounts. Free 500-email scan. No credit card required.

Unblocked — Get AI agents to generate code that fits your system.

I built this because my wife and I kept running out of storage in Gmail. Finding one email with a big attachment is easy — but what about 4,000 emails from a retailer that add up to 2GB? That's the problem nobody had solved.

So I built EmailSlim to rank your inbox by total sender storage size. The moment I ran it on my own account, I found old real estate MLS listings from 2013, thousands of retailer emails, and senders I had literally never opened. Gone in minutes.

In beta, users deleted tens of thousands of emails, and more several told me it was actually fun!

We only access metadata, not the email content. Every deletion is user-approved.

Would love to hear what you find in your own inbox!
