Let your app send
real letters
One API call with a PDF and an address, and we print, envelope and post the letter anywhere in Sweden. No sales call, no contract with the postal service. Works just as well from Cursor or Lovable as from your backend.
No sales rep in the way
Other mail services want to book a meeting first. Here you create an account and pay per letter.
Registered when it matters
Receipt, tracking and a copy of the letter are stored together, so you can show what was sent and when.
Built for AI coders
Clear docs and ready-made prompts, so Claude, Cursor or Lovable can wire up your letters for you.
How it works
Three steps from your app to the recipient’s mailbox.
- Send a PDF and an addressOne call from your app, or let your AI coder write it for you.
- We print and postMake as many calls as you like. All letters go into a daily batch and are posted the next working day. The cost is deducted from your balance.
- You get notifiedStatus is sent to you by webhook when the letter has been posted and when a registered letter is signed for.
import { Brev } from "brev-api"; const brev = new Brev(process.env.BREV_API_KEY); await brev.letters.send({ pdf: invoice, to: { name: "Anna Andersson", address: "Storgatan 1", zip: "702 10", city: "Örebro", }, service: "registered", });
# Send a registered letter curl https://api.brev-api.se/v1/letters \ -u $BREV_API_KEY: \ -F file=@invoice.pdf \ -F to_name="Anna Andersson" \ -F to_address="Storgatan 1" \ -F to_zip="702 10" \ -F to_city="Örebro" \ -F service=registered
Add physical letters to the app with BrevAPI. When an invoice is 14 days overdue, the customer should get a reminder as a letter to their postal address. Use BREV_API_KEY from the environment variables and follow the documentation at https://brev-api.se/llms.txt.
