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.

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.

Any group that runs or supports advocacy campaigns can apply. After you submit the registration form, our team may review and approve your organization. Once approved, you can join platform causes, create campaigns, and invite advocates to add their voices.

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.

Yes. We use Stripe for payments. Your card details are not stored on our servers. Payment is one-time per order; you only pay for the letters you send.
