Take a Tour

Save time and protect your email address.

Control who can send you email in an airtight way.
Less Email. Stop giving out your email address online.
All-day focus. Combine all mass mailings into a single daily digest email.
Scam Shield. Find out who tries to sell your email address.

Our inboxes are loaded with unproductive noise.

Newsletters and sometimes even coupons we'd love to receive, but that clutter our inboxes, so we always archive them. Social notifications that tug us out of productivity throughout the day. Spam when someone sells our email addresses to others.

Throttle is a smart browser extension that generates unique email addresses in signup forms all over the web.

A button is added to all email form fields. Instead of entering your real email address, just click the Throttle button, and a unique email is generated and filled into the field. All you have to do is submit the form.

It combines all the messages you receive into a single daily digest email.

You can revoke any sender's access,
which shuts down their unique email address.

Find out who tries to sell your email address,
and shut them down with a single click.

Another great benefit of each sender having a different email address to contact you with is that Throttle can detect who sells or steals your email address. When this happens, you'll get an alert, and all you have to do is click 'Revoke Access'. Throttle shuts down the unique address they had to contact you with.

They have no way into your inbox, because they never had your real email address in the first place. They could keep selling your address to anyone, but none of them will be able to get through.

Throttle up your productivity with these powerful features.

See the features we built on top of Throttle's innovative core. From a reader much like an RSS reader, to categories with their own weekly or daily digests, Throttle has everything you need to power up your email productivity.

Features »

There's more.

The core of Throttle is the magic, but we didn't stop there. There are all kinds of other benefits and features you'll discover with Throttle. Here are a few of our favorites.

Productivity


Organize with Categories.

Freely subscribe to newsletters without the inbox clutter or risk of abuse. Organize all the content you receive into categories like Social, Shopping, Newsletters, Business, Health, and Food.

Get a single digest.

Instead of the dozens of messages that would interrupt your day, Throttle summarizes them all in a single, daily digest scheduled when you want it. Set Category-specific digest settings, switch to weekly, turn it off - it's all up to you.

Fits into your workflow.

You'll never need to remember to check a separate tool. Throttle's browser extension automatically adds a button to all signup forms that unique generates email addresses, and a daily digest is delivered to your inbox once a day.

Enjoy fewer interruptions and less clutter.

All the newsletters, mass mailings, junk, and other unimportant emails you get throughout the day bury the important stuff in your inbox. Throttle gets those out of your inbox, and into a single digest.

No more 'unsubscribe'.

Your non-Throttle-using friends will still be stuck with today's best solution: requesting that other people remove their email addresses from their mailing lists, in 7 to 10 days. But you have Throttle. You'll just revoke access.

Content


Manage your subscriptions.

Who knows whose email lists you're subscribed to right now, whether you want to be or not. With Throttle, you can manage your email subscriptions, much like an RSS reader. See what you're subscribed to, what they've sent you, and you can always turn them off.

Curate your own digests.

With Throttle, you can put related newsletters into categories with their own digest settings, and you can safely subscribe to all the mailings you might get interesting content from, without them burying your inbox.

Read on your own time.

Schedule your digest for a time that works for you. Lunchtime? Evenings? Read those less important emails during some downtime in your digest, or in the beautiful Throttle news reader.

Security


Throttle doesn't access your email.

It sounds crazy, but it's true. Throttle does everything it does without ever needing access to your email. It doesn't scan your inbox, because it stops mass mailings before they even hit your inbox. Keep your email account credentials private.

Signup on websites without fear.

No longer fret over signing up for something online. With Throttle, even the most abusive sender can be shut down in an instant, and their messages never hit your inbox. It's safe and easy to sign up for any newsletter, account, or make a purchase.

Control who can send you mail.

Throttle gets you a cleaner inbox, and a great way to read & organize your newsletters online.

Stop giving out your email address.

Throttle keeps your email address secure and private: you no longer have to give it out to untrusted websites.

Do you send marketing emails and newsletters?

There's tons in store for email marketers and mass mailers. Here are just a few major benefits of your subscribers using Throttle to enjoy the content you send them.

Automatic Whitelisting

When a subscriber authorizes your newsletter with Throttle, you are automatically whitelisted, so there's no need to request that a user do it manually.

100% Deliverability

The holy grail of sending mass mailings: you get 100% deliverability with Throttle users.

No Spam Reports

A user's first and only step to stop unwanted email is to revoke access, so you don't have to worry about spam reports with Throttle subscribers.

Higher Conversion Rates

During our testing, something we didn't predict but that we found out very quickly: Throttle users are much more likely to subscribe to your newsletter, because they don't have to worry about vetting your privacy policy first.

Optimized Delivery Time

The best you can do is average out the best time to send your mass mailings to all of your users, even if that isn't a great time for most of them. Throttle users pick the most convenient time to receive your content.

Full HTML5 + CSS3 Support

Your email is displayed in the user's supported browser, with nothing stripped out. You can take advantage of all the full HTML5 & CSS3 that you want.
