Frequently asked questions

Millions of Voices is an advocacy platform for causes, campaigns, and coalitions. Individual supporters can browse causes, choose representatives or embassies, and send physical letters through our partners. Organizations can register, run campaigns, and coordinate outreach at scale—including summit-style letter programs when your workflow is set up that way.

Petitions are often filed without individual review. Email is bulk-processed by congressional mail systems. A physical letter takes staff time to open, route, and respond to — especially when it arrives on letterhead before a meeting your advocate is attending.

You pick a cause, find your representatives (by name, address, or embassy), write your personal message, choose a card design and handwriting style, and place an order. We handle printing and mailing so your letter reaches the right office. Payment is per letter via secure checkout.

Letters are sent through our partner Handwrytten, which produces handwritten-style letters. Your message is written in the handwriting style you choose so that each letter feels personal and stands out to lawmakers and officials.

Letter pricing covers AI drafting, printing on letterhead stock, first-class postage, and delivery tracking. See the pricing page for current per-letter rates and optional tips or monthly giving at checkout.
