ePluribus lets you send official messages to your representatives at all levels of government. We have a mobile app, a Chrome extension, and an embeddable widget.

(For information about how your representatives receive your message, please see our FAQ.)

Mobile App

The ePluribus mobile app literally puts your representatives in the palm of your hand. You send the message; we deliver it to their official inboxes.

Chrome Extension
Add to Chrome It's Free!

Send official messages to your representatives directly from Facebook, Twitter, and news sites.

The ePluribus Chrome extension integrates with Facebook and Twitter so you can turn your posts and tweets into official messages to your representatives. It's a seamless integration that allows you to speak your mind to your friends, followers, and representatives at the same time. ePluribus transforms social media from an echo chamber into a public forum.

ePluribus also integrates with millions of articles across 14 major U.S. news sites. Just like with the Facebook and Twitter integrations, you can contact your representatives without leaving the page. After installing the Chrome extension, just look for ePluribus at the end of articles:

Embeddable Widget

Are you a website owner? You can embed an ePluribus widget like this one on your own site with a single line of code:


Aidan and Liam McCarty

We grew up in the small town of Elm Grove, Wisconsin in the suburbs of Milwaukee. Wisconsin has long been a swing state, so it exposed us to a wide range of political views.

When we left Wisconsin for college, we found ourselves between two very different worlds. At Stanford, we saw a place teeming with innovation but ignorant of politics and government. When we spent a summer in Washington, D.C., we saw a city full of civil servants but decades behind in technology.

In the chaos of the 2016 election, we decided to take action. With our unique mix of experiences, we knew that Silicon Valley and Capitol Hill were disconnected from each other and out of touch with the rest of the country. The candidates and the news were so polarized and partisan, but most Americans were not. Somehow our political system had stopped working for everyday people.

So, we built ePluribus to help people be heard, to help you be heard. You can contact your representatives as a verified constituent and make your opinions count.

How do my representatives receive my message?

We deliver the message to your representatives' official systems. The mode of delivery varies by the type of representative, but they receive your message as if you contacted them directly through their website or another official channel.

For a message sent using our widget at the end of a news article, we include a link to that article at the beginning of the message so your representatives have the appropriate context. When you send a message with the mobile app, Chrome extension or widget, we show you exactly how your message will appear to your representatives.

Soon, we will also send you an email receipt for each message. This receipt will include information about how your message appears to your representatives.

Is ePluribus affiliated with Facebook, Twitter, or news sites?

No. ePluribus provides functionality on top of those platforms but is not affiliated with them in any way. Those platforms have no access to the personal information you provide through ePluribus.

How does ePluribus handle my personal data?

We are committed to and passionate about data privacy. Our goal is to store as little information as possible. The only personal data we collect is what we explicitly ask for when you create your account, and we use this to send messages to representatives on your behalf and communicate with you. You can read more about this in our privacy policy and terms of service.

Do representatives need to use ePluribus to receive my messages?

No. Representatives receive your messages even if they have never heard of ePluribus, and they can respond to you by email.

Is using ePluribus on social media different than tagging representatives?

Yes. If you tag representatives on social media, they will likely never read what you write. When you post with ePluribus on social media, we send the text of the post as an official message to your representatives. They will receive it in their existing systems, just like if you filled out the contact forms on their websites.

How is ePluribus different than other civic engagement tools?

ePluribus is different in at least two crucial ways:

  1. It meets people where they already talk about politics: on social media and news sites. Other platforms (e.g. Countable, 5 Calls, and Brigade) are standalone, but ePluribus integrates with what people already use. Nearly half of Americans post about politics on social media.

  2. It will allow every user to verify their identity to prove they are a constituent (this feature is coming soon), making representatives far more likely to pay attention to their messages. Even the most prominent civic engagement tools (e.g. ResistBot,, and have no identity verification, making it all too easy to spam representatives.

Why is identity verification important?

Identity fraud is wreaking havoc on our democracy. Fake accounts on social media are fueling misinformation campaigns both foreign and domestic, making it easier than ever to meddle in our politics. Fake messages are flooding representatives and federal agencies, drowning out the opinions of real Americans. For example, the FCC recevied 21.7 million public comments about net neutrality in 2017, but Pew Research found that 94% of them were fake or duplicate. The Justice Department launched a criminal investigation into this last December.

ePluribus is committed to stopping bots, lobbyists, spammers, and foreign agents from drowning out the voices of real people like you.
