Spark 2.0 continues to offer the same feature set for individual users, but it introduces a new collaborative email experience for teams.
Teams can use Spark 2.0 to discuss email using private in-line conversations, share emails through email threads rather than forwarding, collaborate on emails, and create links to email threads that can be shared in various ways with security settings to control who can view it.
In Spark 2.0 for Mac, there's a full-featured Calendar available to Spark for teams users, and on iOS, there are third-party integrations for Reminders, 2Do, Omnifocus, Things, Wunderlist, Todoist, Asana, Trello, Bear, and Files.
Spark is going to continue to be free for all individual users and core team functionality will be available at no cost, but a fee will be charged for teams who want upgraded features.
A premium Spark subscription for teams is priced at $7.99 per month per user, a fee that includes additional storage for comments and file sharing (5GB is available free), 3 or more collaborators for composing an email, premium customer support, advanced link sharing options, and access to admin settings and controls for the team.
Spark 2.0 can be downloaded on iOS devices from the iOS App Store [Direct Link], and on the Mac from the Mac App Store. [Direct Link]
