The free version of Spark now includes the same features as before, along with the unified inbox, the new smart inbox, and the updated design. Unlike before, Spark is moving to a new subscription-based model. Users can now choose to accept the incoming email from the sender or block the sender entirely. Spark is also introducing a new feature called Gatekeeper, which automatically scans all incoming emails from new senders and displays them as cards at the top of the inbox. Emails can now be marked as 'done' rather than unread in the new Smart Inbox as part of Spark's goal to rethink how people interact with emails. Now, the new design introduces bundles for different email categories such as newsletters and notifications. Spark on the Mac now has an entirely new design that maintains the same elements as before, such as a unified inbox, but with new additional features. The popular email client Spark today announced a significant redesign for its Mac app, introducing new features to make it easier for users to manage their emails, reduce distractions, and have a more streamlined emailing workflow.
