Post to people and channels from HRIS-driven audiences, turn an email into a Slack post in one step, and see reactions and clicks.

Slack is the workplace chat app for many tech and fast-growing companies. ChangeEngine posts updates to people and channels in Slack, converts an email into a Slack post without a rewrite, and reads reactions back.
See every integration →Audiences from your HRIS, plus the Slack channels you choose. Personalization with first name, manager and location.
Every post is previewed and test-sent before a person publishes it. Nothing posts on its own.
Editors only see what their role allows, and every change is logged.
When something changes in your system of record, the right people hear about it on the right channel. Nobody on the People team presses send.
New hires get a Slack welcome on day one, with the channels to join and their first-week plan.
Updates post to the right channels and to individual people, from one draft.
Convert an email you already wrote into a Slack post without starting over.
Managers get a Slack nudge for team milestones and new starters.
Anniversaries and shoutouts post to the team channel, with a message from the manager.
Reactions and clicks come back for each post. Slack does not report opens, so we show what it does measure.
