# Mail

Free · in build

Read your mail alongside the people who sent it.

## What you can do

- Read and send from inside Cashel
- A message opens the person who sent it

## Works with the other apps

The free apps share records. Open a contact in one app and follow their documents, figures or messages into another. You do not need to enter the details twice.

## Your data

Everything Mail holds lives on a machine you choose: your computer, or an always-on machine in your office. On those setups we never receive your business data.

## What it costs

Nothing. Mail is free, like every free app: no licence and no seat rent, for any number of people.

Software is bought once and owned; the only subscriptions are optional ongoing services — hosting, payments connectivity, and AI connectivity (bringing your own AI model).
