Campaign Launch Time
One Organization. One Staffer. 3,490+ Letters and Counting.
A national advocacy org signed up, and we helped them build their first advocacy campaign for free. Here's what happened next.
We Built Their First Campaign Together
Free onboarding call. We helped them build their first campaign — targeting bills in both chambers, selecting legislators by committee, uploading their letter, and adding talking points and facts for AI personalization.
Shared With Their List
Emailed the Campaign Page link to their supporters. Each person entered their address, got matched to their exact representatives, and sent a personalized letter with their own story. 862 letters on the peak day alone — every one different.
First Month Results
1,020 advocates across 49 states. 357 federal legislators contacted. The bill picked up 3 new cosponsors that month.
The Campaign Evolved
The campaign kept running. New supporters joined weekly from social shares and email forwards. 3,490+ total letters to 480+ legislators — still managed by one staffer.
3,490+ letters. 480+ legislators. Federal and state. All 50 states + DC.
One staffer. One platform. Live in under five minutes.
“Brilliant and strategic — our small nonprofit reached millions of people and sent more letters than most major animal welfare groups ever have.”

We Know What Nonprofit Advocacy Teams Face
53%
Struggle With Staffing
More than half of nonprofits struggled with adequate staffing and turnover in the past year (Forvis Mazars, 2024 State of the Nonprofit Sector). Legisletter is simple enough for one person to run and powerful enough for a full advocacy team — launch, manage, and report on campaigns without a steep learning curve.
32%
Know They Can Lobby
Only 32% of nonprofits know they can legally support or oppose legislation — down from 54% in 2000 (Independent Sector, 2023). Fear and confusion are the biggest barriers to advocacy. Legisletter makes constituent communication simple — consult your legal counsel on lobbying limits.
25%
of Nonprofits Lobby
Down from 74% in 2000 (Independent Sector). Three out of four nonprofits have left the policy arena entirely — citing cost and complexity. Legisletter tackles both.

“You have now given your voice to the voiceless.”
Dawn Olivieri — actor, producer, and animal rights advocate — walks through exactly how she uses Legisletter to mobilize supporters for animal welfare legislation. Enter your address, review the AI-personalized letter, hit send.
“All you have to do is really simple... the AI will actually build out the letter for you. You can go in and fine-tune it. You can make it your own.”

Nonprofit Advocacy FAQ
How fast can we launch our first campaign?
Under 5 minutes. Paste your policy brief or bill number, select target legislators, and you get a branded Campaign Page with a shareable URL and embed code. Share it with your supporter list and they start writing personalized letters immediately. No onboarding process, no training sessions, no IT tickets.
How are letters delivered to Congress?
Federal letters are delivered through official legislative contact systems — the same channels constituents use to contact their representatives directly. State legislature letters are delivered via direct email to legislators’ official addresses. These are official constituent communications, not bulk email.
What makes this different from other grassroots advocacy software?
Most grassroots advocacy software sends form letters that congressional offices batch and tally. Legisletter generates a unique, personalized letter for every advocate based on their own context, perspective, and legislator intelligence. Letters automatically reference the bill’s details, adapt messaging based on the legislator’s party affiliation and cosponsorship status, and incorporate your policy brief or fact sheet. Every letter is different, every sender is verified, and every communication goes through official channels.
What reporting can I show my board or funders?
Real-time dashboards show letters sent, legislators contacted by name and district, geographic distribution of supporters, and campaign conversion rates. Every metric is auditable — you can show exactly how many verified constituents in how many districts contacted how many legislators.
Can I add the Campaign Page to our website?
Yes. Embed your Campaign Page directly on your website so supporters take action without leaving your domain. Responsive design works on mobile and desktop.
Does Legisletter integrate with our CRM or email tools?
Yes. Export advocate data (name, email, state, district, opt-in status, letters sent) as CSV. Mailchimp integration is built in for adding advocates directly to your email lists. API access available on Enterprise plans for direct CRM integration.
Can our supporters share the campaign with their own networks?
Yes — and this is where campaigns take off. Every Campaign Page has a shareable URL that supporters can forward via email, text, or social media. When someone new clicks the link, they go through the same process: verify their address, review their personalized letter, and send. No account needed. Some of our most successful campaigns grew organically through supporter shares — reaching people your email list never would.
