AddUp is Retired
AddUp was a Sierra Club-built (at the start in partnership with Blue State Digital) platform that allowed you to set up an online homepage for your campaign where you could host a variety of online actions -- from petitions, events, social media shares, volunteer sign-ups, and more.
Retirement Update
AddUp was shut down as of December 15th, 2025. An almost 10 year run.
