Common Questions

How do I mass unsubscribe from emails in Gmail?

Gmail's Manage Subscriptions feature lets you unsubscribe one sender at a time. For true bulk cleanup, CMDK's Nuke feature blocks a sender and deletes all their emails in a single click. No need to unsubscribe one by one.

Is there a way to unsubscribe from all emails at once in Gmail?

Gmail does not have a button to unsubscribe from all emails at once. CMDK's Nuke feature is the closest thing: click the block button on any sender in your toolbar, and all their emails are deleted and future emails are blocked instantly.

How does CMDK Nuke work?

When you see an email from a sender you want to get rid of, click the Nuke button in your Gmail toolbar. CMDK blocks the sender so you never hear from them again and deletes every email they have ever sent you. One click, fully gone.

Is CMDK Nuke safe? Will it delete emails I want to keep?

Nuke only targets the specific sender you choose. It will not touch emails from other senders. If you accidentally nuke a sender, you can undo it. See our guide on how to recover accidentally nuked senders.

Does CMDK read my emails?

No. CMDK does not read or store your emails. It runs locally in your browser and only accesses Gmail to perform the actions you initiate. Unlike third-party inbox cleanup tools that require full access to your email, CMDK keeps your data private.

How is CMDK different from Clean Email or Unroll.me?

Clean Email and Unroll.me are separate services that require full access to your email account to scan and categorize your messages. CMDK is a Chrome extension that works inside Gmail without reading your emails. Nuke is one feature within a full productivity suite that also includes keyboard shortcuts, command bar, reminders, and read receipts.

Does CMDK have a free trial?

Yes. 15-day free trial with full access to all features including Nuke. No credit card required.

Can I see CMDK Nuke in action?

Yes. Watch this short video to see how Nuke works: Watch on YouTube

Nice app. I like Gmail UI, but the shortcode options of Superhuman. So your app is the best of both worlds!

How to Bulk Unsubscribe from Emails in Gmail | CMDK

Brian Dainis

Literally the best email extension you could get. Amazing alternative to Superhuman. Super clean and just works. Definitely worth the price and they are super responsive to feedback.

Danny Nielsen

Solid extension that provides many of the key benefits of MUCH pricier tools. Even better that this lives in Gmail, so you can use other extensions as well.

Zachary Eisenstat

Great - simple as it says, but adds a bunch of convenient time saving features. I don't need a full on client, I just need my Gmail to be fast, and this does it.

Dilip Goswami

Really good and helpful. And the developer was even very responsive to feedback!

Dominic Roser

This is awesome. It massively speeds up and simplifies usage of Gmail. Great pricepoint too, and the developer is super active and amazing at feedback and improvements.

Brent Maxwell

Love it! This extension helps me fly through my emails so I can get out of my inbox and back to revenue producing work. And great support!

Bill Brelsford

Works like a charm! Exceptionally GREAT SUPPORT - even for as small language as Hungarian. It can totally replace Superhuman.

Zoltán Szabó

I have started using CMDK as a layer over my gmail. Once I got used to it I love it. CMDK provide real-time support - most impressive!
