The complete app description is here, so in this post, we are going to focus on how to use the application. In this post, we are going to show you how to export Slack data with the help of Backupery for Slack application. As you might already know Backupery for Slack makes regular and scheduled backups of Slack data to the destinations of your choice. So the tasks of export, import, regular backup, splitting, or merging workspaces occur regularly. Once they no longer appear online, send them a message and see of they come online without having to reopen the app.Slack is a highly popular collaboration tool that is used by teams all over the world. Have them login and leave the app alone for some time. You can test this with someone that has the Slack app on their phone. Having said that, it might be possible that a user's account is "sleeping" and the act of receiving the message sets them as online. That is a likely indication that they read it.
If they are offline when you message them, wait around to see if they appear online shortly after you send the message. You'll know they read it if the notification isn't there, but they may have also seen it even with the notification showing, due to other unread messages. Look at their screen to see if their Slack app is showing the unread message notification. There isn't much you can do outside of asking if they saw it. Unfortunately there is no read receipt feature, although it is on their dev backlog according to this Tweet thread.
