Ask a question or request a capabilityHandled by AutoLetters, not by Lenny
These parts of AutoLetters happen in the product itself, with your approval. Lenny does not carry them out:
- Design studio artwork generation, previews, versions and approvals
- AutoPostcode area audiences and CSV recipient uploads
- Stripe checkout, credits, subscriptions and refunds
- Stannp proofs and dispatch after human approval
- SendGrid account, payment and order emails
- Results and redemption tracking
How it works
- Tell Lenny your goal. For example: "Bring lapsed customers back to my café with a spring offer" (illustrative).
- Answer a few questions. Area or recipients, offer, quantity and how you want to measure responses.
- Review the plan, then carry on in AutoLetters. Design and approve artwork, choose recipients, see the price and order. Nothing is printed or posted until you approve and pay.
What you need: your business name, what you want people to do, and roughly who should receive it. No account is needed to start. See pricing · See formats · How AutoLetters works
Who Lenny is for
UK local and small businesses such as cafés, salons, trades, estate agents, gyms and independent shops, along with the agencies who run campaigns for them. If you want printed, addressed mail without learning print specifications, Lenny is a good place to start.
Connections
Lenny works inside the AutoLetters web app. AutoLetters uses Stannp for printing and posting, AutoPostcode for UK addresses, Stripe for payments and SendGrid for emails. Lenny does not use these directly. There is no public API or MCP server for Lenny's capabilities. If you need one, ask us.
Lenny's personality
Warm, brief and practical, in plain British English. Lenny asks no more than two questions at a time, keeps replies short and does not invent prices or claims. He is an AI persona, not a member of staff.

Tell us what you need. We'll assess it and, where we can, aim to deliver the same working day. We'll confirm what is possible and the timing for your request before you commit to anything.
Questions
Does Lenny post my mail?
No. Lenny plans and drafts. Printing and posting happen in AutoLetters only after you approve the artwork, recipients and payment.
Do I need an account to talk to Lenny?
No. You can start planning as a guest, and your plan carries over if you create an account later.
Which formats can Lenny recommend?
Only what AutoLetters can print and post today: A4 letters and A6, A5, A5 portrait and enveloped A5 postcards, plus A3 folded to A5.
Does Lenny set prices?
No. Prices come from the AutoLetters price list, which you can see on the pricing page before you order.
Can Lenny connect to my CRM or another system?
Not today. If you need that, ask us using the form. We will assess it, usually the same working day, and confirm what is possible.
Is there a public API or MCP server for Lenny?
No. There is a small public endpoint for sending enquiries only, documented below. It does not run Lenny or place orders.
