Community Voice & Feedback
Really nice concept, way more convenient than running to the post office. The way it just works behind the scenes and you forget it's even mail feels seamless.
That stamp-licking problem is such a classic annoyance, love how clean and focused the whole concept is. The branding feels really thoughtful too, the name and tone make it feel friendly instead of corporate.
Gotta say, the branding here is genuinely charming. That name "Pieter Post" with the classic envelope vibe really sells the whole concept before you even read what it does. Smart move leaning into the postal heritage while modernizing the actual experience.
MCP for postal mail is a pretty novel idea! I can imagine a use-case where you'd want your agent to send out postal advertisements or have it send your friends and family holiday cards or even handle the shipping for small online businesses. I'm curious, is letter/package tracking also included w/ the PieterPost MCP tool? Because that could also be an interesting feature to have.
Love seeing MCP tools that result in real physical objects. Good stuff!
Two things for me. First, the fully resolved postal address read back verbatim, plus which Mailbook entry it matched, since 'John in London' quietly resolving to the wrong saved contact is the failure I'd never catch. Second, an idempotency key on the send, so if the agent's tool call times out and retries I get one postcard and not two. Duplicate physical sends are the money version of a double-submit.
Finally tried Pieter Post for a birthday card to my grandma and it worked like a charm. The whole process took under a minute and the handwriting on the envelope actually looks legit.
Uploaded a letter from my phone yesterday and it showed up at my mom's place two days later, tracking included. Genuinely didn't expect the whole process to feel that painless.
There is something lovely about a real letter landing in someone's hands, and making that as effortless as tapping out a message is a delightful little bridge between the physical and the everyday. Nicely done, Pieter.
Love it! 😍 How are you thinking about pricing the MCP side? Is it just pay per letter/postcard sent, or will there also be something like a monthly/API plan if people start wiring this into their own tools? Mostly asking because this feels like something I’d try once manually, then immediately want to automate if it works.
The Mailbook integration seems really useful. Having contacts ready instead of entering addresses every time could save quite a bit of effort
Congrats on the launch. I never expected postal mail and AI agents to come together, but this actually makes a lot of sense for businesses that still rely on physical communication.
How does Pieter Post actually handle the physical delivery part, do you print and mail things on my behalf or is there some kind of kiosk pickup I need to visit nearby?
Letting an agent create a checkout link before anything mails is a clever gate, but I'm curious what the agent actually sees back after it uploads a postcard image. Does it get any confirmation of how the final print looks, or is it flying blind on the physical artifact once payment clears?
Connecting AI agents to physical mail is a genuinely underexplored space. The irreversibility angle is the interesting design challenge here — curious if you're adding a confirmation step before anything actually ships, since a hallucinated address isn't a retry, it's a stranger's mailbox.Would love to see a "draft mode" where agents prepare everything but a human approves before it goes physical.
