Spark collaboration with tools for teams

Spark is the perfect tool for businesses, allowing you to compose, delegate and manage emails directly with your colleagues - use inbox collaboration to suit your teams dynamic and workflow.

Create together

Get your communications spot on by collaborating with your team in real-time. No more pinging back and forth.

Share information

Turn email into chat with private comments. You can even add attachments within the comments.

Team management

Delegate ownership, track progress and set deadlines for your team with ease. Never miss a beat.

The set aside function, the home screen and the division between personal and automated email will be the most helpful. I like gatekeeper - especially that you can look into it before deciding.
