Envelope
Message Read Receipts for Slack Teams
When you send message in Slack, you have no idea when it is read.
Sometimes you want to send really important message and it's frustrating when you don't get a reply for a long time.
With Envelope App your message will be hidden from recipient until special button is pressed, effectively confirming that message seen and read.
Just put special /envelope command in the beginning of your message.
We would welcome any feedback.
