The foundation

Every plan comes with the foundation: a service working around the clock to protect your inbox and your time. They both include the daily digest, browser extensions for all the major browsers, revoke access, and Spamsense will alert you if someone sells or steals your email address. Plus, you can use Throttle on your iPhone or iPad with the iOS app, which is always in sync with your Throttle account. It has a browser extension so you can generate addresses seamlessly on mobile.

You want me to pay for software?

We know it sounds crazy, but hear us out: we’re a few independent designers and developers in Virginia and Tennessee. If we can make a living off of our software, then that means more great software for you. If we can’t, that means an industry filled with free bloatware with shady business models that’ll get acquired and shut down just when it starts to get good. So consider it an investment in your current and future productivity.

Frequently Asked Questions

How do I log in to an account using a Throttle address?

Throttle's biggest fans love to use Throttle for their social media and other online accounts. That way, notifications don't bother you all day; you know they'll come to you in a single daily digest email.

The Throttle browser extension will automatically fill login form fields with your generated address so you don't need to worry about finding it to login.

Won't marketers be unhappy about this?

Throttle is actually great for legitimate senders as well. Here are some benefits they enjoy with their subscribers that use Throttle:

  • 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.

Can I use my own domain for my generated addresses?

  • When the sender had a data leak, and spammers stole the addresses (resulted in hundreds of emails)
  • When the sender had a software glitch that resulted in over 500 emails

Read more about the first case, here.

What if I want to migrate my subscriptions away from Throttle at some point?

Then all of your addresses will look like this: "". If you ever want to migrate away, you can just set up a catchall at the domain and forward it along to whichever address you want to continue getting these messages.
