Give your AI assistant hands: connect once, and it can mail
real USPS letters for you — inside a monthly budget you control.
Start below — tell us whose account this is and the monthly
budget cap.
Save a payment method — card, Apple Pay, or Google Pay,
on the secure page that follows.
Get your API key — shown once. Add it to your assistant's MCP
configuration and it can draft and send inside your cap, with no per-send
prompts.
Nothing is charged during setup. Sends are billed against
your saved payment method only when a letter is mailed, never above your
monthly cap. See our privacy policy.
