Customizable email app Spark has just launched Spark 2.0, which adds a host of collaborative features for team members to work on and discuss emails together.

Now, if you’d like input on an email you’re drafting or on how to respond to an email you’ve received, you can share it with other people and have a private chat conversation below the compose area. You can also draft an email by inviting others to join a real-time editor. (Think of it like Google Docs but inside your email.) Lastly, Spark now allows you to create links to specific emails or threads that can be shared with other people in docs or apps like Slack. Permissions can be set to make sure only specific people can access the shared emails.

There’s also a new calendar that takes natural language into account so you can write in appointments like, “meet Alex tomorrow at 10AM.” Spark also integrates with a multitude of services, like Dropbox, Box, iCloud Drive, Evernote, Reminders, Wunderlist, Todoist, Asana, Trello, Bear, and Files, all with custom designs to ease transitioning content between apps.

Spark 2.0 will be free for existing Spark users, and it’s currently available for iPhone, iPad, and Mac. Spark 2.0 for watchOS will be available in the near future.
