Vivaldi Mail 2.0
For you to get the best experience of Vivaldi Mail, we have enabled prefetching by default with the update to 2.0. From this version, the default behavior will be to automatically download the last 30 days’ worth of emails, and retrieve all messages visible on the screen. This will optimize search in your inbox by allowing you to search for any part of a message. It will also let you see a preview of the messages in your inbox, even when offline. You will be able to select different intervals for prefetching to match your own needs.
