What they see when they scan

The card earns the scan. This page carries the pitch: built for one person, assembled from your profile and that card.
Taylor,

Greeted by name

The page greets them by name and carries a short note you wrote for that card.

Include your video and calendar

Both are optional. Record one short video and reuse it, pick a different one per card, or skip video entirely. Your booking link sits right under it, so watch-then-book is one motion, and the page works just as well with only your links.

Fully tracked in your dashboard

Every visit, video play, and tap lands on the card record, timestamped. The page itself shows only you.

Every card and stage tracked to the person

A unique QR on every card means per-card tracking: who scanned, what they tapped, and which cards turned into meetings.

The research and the AI writing in the next two sections come with every plan.

It researches before it writes

Every card is written from three layers: what your company does, what is true about this person and their company right now, and what you know that the web does not.

Your companyRead once, at signup

At signup, Stampline reads your website and drafts what you do and the proof points worth citing. You edit it once, and every card draws on it.

Their company and themResearched when you save a contact

When you save a contact, Stampline researches them and their company and writes what it finds into Notes: recent news, their current role, what the company says about itself, each fact with its source and date. Anything it cannot verify never makes the card. You can edit, remove, or add to the research at any time.

Your notesWhat you know goes in last

Anything you type about the recipient outranks anything the web says. The card is written from all three layers, in 450 characters, and it is yours to approve before it mails.

Built for teams

One pool of cards the whole team draws from, and a dashboard that shows who is sending, who is booking, and what it closed.

One pool, every rep draws from it

Team plans share 70 cards a month. Nobody waits on a personal allotment, and the admin sees the balance and the reset date at a glance.

Tracked to the rep and the recipient

Every scan, click, meeting, and closed deal rolls up to the person who sent the card. Click a rep to open their own dashboard.

Admins and members

Admins invite and remove members and manage billing. Members see their own contacts, cards, and numbers. Everyone writes from the same company profile.

How it works

You write the card, or the AI personalizes one for each recipient. Either way, you approve every word before it mails.
1

Write it, or let AI personalize it

Pick a contact and an occasion. Draft it yourself or let the AI write a card shaped to the person, then edit anything before it sends. Personalization runs on Anthropic's Claude, working from a writing system built on decades of direct-mail craft.

2

Penned in real ink, mailed with a real stamp

Your card is handwritten with a real pen on heavy linen stock, hand-addressed, and sealed in an invitation-style envelope. Envelopes like that get opened, kept, and remembered.

3

The QR turns paper into pipeline

Every card carries its own unique QR to a personal landing page with your video and booking link, so every scan and tap is tracked to the individual card.

No Stampline branding anywhere on the card or the envelope. It comes from you, not us.

When a card does the work

Five moments where a card on a desk outperforms another email in a queue.
Cold outreach

Generate leads that email can't

Your prospect's inbox filters you out before they see your name. A hand-addressed envelope gets opened at their desk, read, and kept. The QR books the meeting.

Follow up

Stay in the deal after the meeting

Everyone sends the recap email. One card on their desk keeps you in the room for the weeks it takes to close: it's kept 17 days on average, not 17 seconds.

Thank you

Say thank you, earn the referral

The opportunity isn't over once the agreement is signed. A written thank you leaves a lasting impression and is one of the most effective ways to ask for a referral.

Re-engagement

Wake up accounts that went quiet

The lead that ghosted, the customer that lapsed, the champion who changed jobs. A card arrives without an unsubscribe link and reads like a person, not a sequence.

Recruiting

Reach the person who isn't looking

Top candidates don't answer InMail. A card at their desk is private, arrives without their employer's filters, and the QR carries your pitch. No applicant portal in sight.

Want proof? We'll mail you one.

Add your address and we will mail you a real card: penned in real ink, hand-addressed, with a QR you can scan yourself. The product will speak for itself.

Common questions

The short answers. Everything else: info@stampline.io.
What is Stampline?
Stampline is AI-personalized handwritten direct mail for sales and recruiting teams. Each card is penned in real ink by a handwriting machine, mailed with a real stamp, and carries a unique QR to a personal landing page, so every card is tracked from send to meeting.
Is Stampline available now?
Yes. Create an account at stampline.app and your first card can be in the mail today. If you would rather see one first, request a free sample card above and judge the product on your desk, not on a screen.
How are the cards actually written?
Each card is written with a real pen by a handwriting machine, in the style you choose. It is real ink on real cardstock, not a printed font, which is why people open and keep them.
Can I customize the card and envelope design?
You choose the handwriting style and control every word on the card and on its landing page. The cardstock, envelope, and design are fixed on purpose: heavy linen stock, a hand-addressed envelope with no company branding, and a real stamp are the combination that gets a card opened and kept.
What sits behind the QR code?
A personal landing page you control, with your intro video, a booking button, and your links. You set the defaults once in Profile; when you send a card you can add a short note to the page and pick the video for that card.
How do I know when someone scans my card?
You get one email the first time a card is scanned, and every scan and tap shows up on the card in your dashboard. No news is just a card still sitting on a desk.
How do I show the ROI?
Every card carries its own QR, so every scan, link click, meeting, and closed deal is recorded against that card and the rep who sent it. Your dashboard shows the funnel from sent to closed-won, revenue per card, and each rep's numbers, so you can put a dollar figure on what a card returns instead of guessing.
Does the card show any Stampline branding?
No. Nothing on the card or the envelope mentions Stampline. It comes from you, not us.
How do plans and card limits work?
Each plan includes a set number of cards a month: Solo is 10, Pro is 20, and Team is 70 pooled across the whole team. Your count resets at the start of each billing period, the same day of the month you subscribed.
How much does Stampline cost?
Solo is $59 a month for 10 cards, Pro is $109 for 20, Team is $399 for 70 cards pooled across the team. Every plan includes the AI writing, the research, the QR landing page, and postage. Cancel anytime.
Can I cancel or change my plan?
Anytime, with no commitment. You can switch plans from Settings, and if you cancel you keep access through the time you have already paid for.
