Ease of use for reading tasks and comments.
Manually need to unfollow tasks you don't want notifications for.
Asana for Gmail is a great tool that allows you to keep on track of the tasks and projects you're working on, while keeping it concise in your inbox. I would definitely recommend this tool.
I work with an incredible team and wonderful clients. That being said, there are a lot of moving pieces and things to keep track of. Having Asana itself allows me to check each and every individual project as needed, but Asana for Gmail allows me to receive a summary of updates for the tasks and projects I'm following in my inbox. This allows me to see everything in one place, better utilizing my time without having to search for each and every project and task that has recently been worked on.
