Automatically save contacts

Proton Mail automatically saves all email addresses you have sent a message to using your Proton Mail account. These email addresses are added to your Contacts along with the default display names associated with the addresses.

The Automatically save contacts feature is enabled by default. To disable this feature (or switch it on again if previously disabled):

1. In the Proton Mail web app, click on Contacts at the top right of your inbox and select Settings.

2. Turn the Automatically save contacts switch on or off to enable or disable this feature.
