Slack Messages Not Sending? Speedify Combines Internet Connections for Failover

Avoid Being Late to the Conversation

A Slack message that will not send, or one that lands five minutes after the thread has moved on, makes you look absent when you are not. The app is waiting on a connection that keeps stalling.

Speedify is an app that runs Slack over more than one internet connection at once – office Wi-Fi and a phone’s 4G/5G cellular data, for example – so messages leave immediately.
