Physical mail for AI agents

Send handwritten letters from your AI agent.

Give your agent one prompt. It can help write the message, collect the mailing address, request an exact quote, and prepare a physical card written in real ink.

YOU STAY IN CONTROL

Review before anything is paid or mailed. Your agent must show you the final message, complete recipient address, warnings, and exact total before asking for approval.

How it works

From conversation to a real card.

Send one letter or up to 100 personalized recipients in a campaign. Quotes and review happen before the payment boundary.

Paste the prompt

Give the copyable instructions below to an agent that can run tools or terminal commands.

Prepare the letter

Your agent gathers the message and complete U.S. mailing address, then asks SendInkwire to render and validate them.

Review every detail

You see the finished message, normalized address, warnings, per-letter price, and total. Changes require a fresh review.

Approve and pay

After explicit approval, an MPP-capable agent can use AgentCash and supported stablecoins to satisfy the payment request.

Track the mail

Your agent returns a private receipt and can check each recipient’s fulfillment status without exposing their address publicly.

Copy and paste

Tell your agent what you want to send.

The full prompt includes AgentCash setup, API discovery, review safeguards, MPP payment handling, idempotency, and private tracking.

Help me create and send a physical handwritten letter through
SendInkwire. You may prepare the letter and payment request, but
do not approve content or spend money until I explicitly confirm
the final message, recipient address, and exact price.

Start by checking whether AgentCash is ready, then ask me for the
letter details.

Why use an agent?

WRITE

Find the words

Draft a personal thank-you, follow-up, invitation, or note in your voice.

CHECK

Catch mistakes

Validate required fields and surface address or message problems before payment.

BULK

Personalize at scale

Prepare distinct messages for a recipient list while keeping every rendered letter reviewable.

TRACK

Follow fulfillment

Keep the private receipt and check progress without repeatedly polling or exposing personal data.

What the agent cannot skip

An agent cannot safely infer your approval. SendInkwire binds the reviewed content to the send, requires a final readiness check, and uses idempotency so a retry does not become another physical action. A paid letter cannot be recalled after fulfillment begins.

Ready when you are

Give your agent the safe path to physical mail.

Copy the complete prompt, paste it into your agent, and describe the letter you want to send. Nothing is paid or mailed until you approve the final details.
