Customize the Infomaniak Web Mail app

Update 07/13/2026

This guide explains how to configure and customize the overall display of the Infomaniak Mail web app (online service ksuite.infomaniak.com/mail) using various options.

 

Introduction

  • The general settings affect all email addresses currently associated with your account in the Mail app.
  • They are specific to your user only and do not affect other users (e.g., within the same Organization).
  • The same email address accessed via the Mail app by another user will have its own settings, independently of yours.

  1. Click here to access the Infomaniak Mail web app (online service ksuite.infomaniak.com/mail).

This section allows you to define the display priority of a received message: either in its simplified plain text version, or in its enhanced HTML version (this setting only takes effect when both formats are present in the email; if only one version is available, it will be displayed by default).

 

Reception: encoding

This section allows you to change the encoding of received messages (it is recommended to leave Unicode (utf-8)).

 

 

Reception: display message preview
