What does Listo ! do?

Listo ! is a free, simple and open source letter template builder.

It allows you to automate a mailing from a spreadsheet for one last time, before you reach out to Slant ! to discuss your journey towards digitalisation.

How does Listo ! work?
  • Upload a list of contacts and their addresses in the correct format
  • Build your template
  • Generate a collection of letters

Then the rest is up to you (fold, stuff, stamp, repeat).

First, upload your mailing list


Be sure to use the correct format
