Your mail.One Workspace.Prepare the letter where you work.

Your envelope speaks before your letter does.

A Workspace that understands the mail

Licko doesn’t collect your documents. It understands the information needed to prepare physical mail — recipient, letter, envelope, weight, postage and services.

    Needs attentionSomething required is missing or incompatible.

Less to remember. Fewer decisions to work out.

Licko checks the mail as you build it — whether the address is complete, the letter fits the envelope, the weight matches the postal product, and the selected services are available.

When something needs attention, Licko shows where the problem is and what can resolve it. When your choice is valid but another option may fit better, it recommends without taking control away from you.

Still true

Physical mail is still moving

  • 10.16BGermany↗
  • 260MUkraine*↗
  • 5.5BFrance↗
  • 1.56BSwitzerland↗

Billions of letters are still moving.

*Ukraine: cumulative since full-scale war (not an annual market total).

Work gets fragmented

1200App switchesper day↗

~4Hours reorientingper week↗

Switch. Find. Reorient. Continue. Repeat.

Working across different tools means constantly switching context.

Research · FAU · 2019

“The objectives, interactions, intermediate results, and final outcomes of knowledge-intensive processes are typically scattered across many systems.”

Doctoral thesis↗

Keep correspondence and its context together.

Licko connects letters, sent mail, replies and the context around them, instead of leaving the process scattered across tools.

Third-party access

Your content does not enter Licko.

Licko can prepare the postal layer using only the information required for the mail. Your document stays with you until you print and post it.

External preparation can expose the document and address data to another intermediary before the letter reaches the postal network.

Frequently asked questions

A short interactive overview — not a stack of collapsed answers.

Desktop Workspace

Is Licko App an iPhone or Android app?

Licko is designed for use on a computer.

licko.app/compose

Does not fit

Licko is a desktop Workspace for preparing physical mail. The envelope, contents, address and postage stay together on one screen, so you can prepare the whole letter in one place.

Mobile is not supported — not in a mobile browser, and not as an Android or iPhone / iPad app.

  • ✕ Mobile browser
  • ✕ Android app

What stays inside the Workspace?

Licko keeps only the information needed for your mail.

Made for physical mail. Not another inbox.

Digital messages stay outside Licko.
