How it works

Create a campaign

Set your target politician, write a suggested script, and choose your campaign window. Call Tsunami auto-generates time slots so calls hit the office in a steady, sustained stream — not all at once and then silence.

Your supporters sign up

Share the campaign link. Supporters pick a time slot, personalize the script in their own words, and get reminders leading up to their call. No app download. No account required.

Watch the pressure build

Track signups, slot fill rate, and self-reported outcomes in real time. See who called, what happened, and where you need to recruit more callers. Share open slots to fill gaps fast.

Call Tsunami doesn't place calls or track whether anyone actually dialed. Your supporters call from their own phones, on their own terms. We coordinate — we don't surveil. That's a deliberate choice.

Built for constituent pressure campaigns. Not phone banking.

Most calling tools are built for organizations dialing lists of strangers — voters, donors, prospects. Call Tsunami is built for something different: getting your own members to call key elected officials.

That's a coordinated constituent pressure campaign. It's one of the most effective forms of civic action. And until now, most organizers were managing it with Google Sheets and email chains.
