Vivaldi Mail comes with email services (IMAP / POP3) and calendar (CalDav). All messages from all accounts will be indexed, so they can also be searched offline.
With Vivaldi Feed Reader, you subscribe to news sources you trust. Most modern newspapers, blogs and podcasts offer news feeds.
With the Vivaldi Calendar, you can choose to keep all your data locally. You can sync a CalDAV calendar, Google Calendar or Outlook.
Because Vivaldi Mail is still in the preview version, it is not enabled by default. To activate it, proceed as follows:
Make sure you download the latest version of Snapshot, install it, and then access:
Vivaldi: // experiments /
to activate Vivaldi Mail.
You will need to restart your browser after doing this.
