We've been having a problem with our team not attending to approval requests. In looking into why, we realized that the email notification does not call out 'Approval Needed' or requested, it just lists the project/task name.
It would be incredibly helpful if it was populated in the subject line, as well as highlighted in the body of the email somewhere. In our exploration, it was buried down in the email and can easily be overlooked as just 'another update'.
With so many email notifications, calling attention to the approvals would definitely help expedite the approval process and avoid unnecessary bottlenecks.
It would also be helpful to call it out in your Wrike inbox as well. Right now it just says, "Person X added you as an approver". Making it more of a 'Your approval is needed' type of message would be super helpful.
