Spark Change Podcast Episode 10: Thunderclap

Watch on

Written by Denise Miller, Firesteel Advocacy Coordinator

Thunderclap is a free tool for posting simultaneous messages from lots of people across multiple social media accounts. Think of it as an online flash mob.

Many organizations and causes have used Thunderclap to amplify their messages across Twitter, Facebook, and Tumblr. Check out these successful campaigns:


The United Nations, with support from Beyoncé, used Thunderclap to introduce World Humanitarian Day to over a billion people. Download the case study.


The nonprofit Get Covered America used Thunderclap to remind Americans to sign up for health insurance. Check out the campaign’s landing page.


The nonprofit WaterAid UK reached almost one million people and more than doubled their Facebook following over the course of their World Toilet Day campaign. Read a blog post about their efforts.

Be sure to also check out Thunderclap’s helpful guide for planning and executing your campaign.
