Throttle Goes Free

Advanced Access Press Kit

Embargoed until Tuesday, March 22, 2016 10 AM EST

Throttle's big splash when it launched in January was dramatic: it is one of the rare few launches to amass over 1,000 votes on Product Hunt, and was featured in an interview with Robert Scoble. The crowd made it clear to us: they want Throttle.

On March 22, we will make Throttle free. Now everyone can have access to world-class protection for their email address, their inbox, and their time.

Solving Email's Biggest Problem

The problem: Our inboxes are buried in mass mailings, coupons, notifications, spam when our address is sold, and even interesting newsletters that just interrupt us. The problem is that when we give out our email addresses online, anyone can dump anything they want into our inboxes.

What you get with Throttle: That's where Throttle comes in. With Throttle, you get airtight control over who can send you email, find out who tries to sell or steal your email address (and shut them all down), get all of your mass mailings in a single daily digest email reducing interruptions throughout the day, and solving the crux of the problem, you get to stop giving out your email address online.

How it works: It works with a browser extension that automatically adds a button to all email form fields online. When making a purchase, for example, you hit the button instead of entering in your real email address. The extension fills out the field with a unique, random email address. All email Throttle receives for you is collected and sent to you in a single daily digest email.

But what’s really interesting is that since we gave each sender a different email address to contact you with, we can detect who sells your email address, and you can hit “Revoke Access” next to any authorized sender, which shuts down that unique email address. They, nor anyone that they give your address to, have any way into your inbox.

Finally, Throttle automatically populates login forms with generated addresses, so you can use them all over the web. You can now do everything you want online without compromising your inbox or your time.

Because of the extension and digest, you don't even have to change your workflow to use it.

As a bonus, it’s (maybe counter-intuitively) great for legitimate senders, too.

Startups, do you have your pitch down? does. This is an interesting email service I met yesterday in Blacksburg, Virginia. It helps reduce the crap you get in email.

Throttle Goes Free

On Tuesday, March 22, Throttle Basic will become 'free forever' — meaning anyone can sign up for unlimited use of Throttle, and it'll never cost a dime. It now includes free access to even more features than were available before.

Throttle Pro Launches

On Tuesday, March 22, Throttle Pro launches with new, advanced functionality.

  • Instant Forwarding
  • Custom Domain
  • Digests for Multiple Email Accounts
  • Attachment & Reply Support via Forwarding
  • Priority Access to Betas (i.e. mobile app)

Throttle Pro will cost $3.99 USD per month.

All prior (paid) Throttle Basic customers will automatically be upgraded to Throttle Pro at no extra cost, but can downgrade to Throttle Basic in settings if they wish.

Security & Privacy

Throttle doesn't need access to your email account to work, so users don't need to compromise their privacy to use it.


Throttle works with all email addresses. Throttle's browser extension, used to generate Throttle addresses in signup forms, is available for Chrome, Safari, Opera, and soon, Firefox. A mobile app is in the works!
