Yes you're right there are apps like Mailmaestro and Superhuman. They're much better than my tool in general. But you're talking about a different kind of tool.

Yes you're right there are apps like Mailmaestro and Superhuman. They're much better than my tool in general. But you're talking about a different kind of tool. My tool recognizes urgent emails based on many criteria and sends an alert only if someone writes an urgent message to you. My tool is good for procurement, logistics, sales and CRM. Where a lot of urgent processes take place.
