Pyn + Slack
Most tools send from a bot and call it done. Pyn gives you multiple ways to send so your message gets read.
Messages people will actually read
Most HR communications get ignored. Not because people don't care. Because they feel like broadcasts - generic senders, off-platform portals, messages that arrive too late or too early.
Pyn delivers through Slack, from a real person, at exactly the right moment. Employees read it and reply because it looks like a message from their manager. They never know it was automated.
Choose who the message comes from
This is where Pyn is different. Most tools send from a bot and call it done. Pyn gives you multiple ways to send, and each one changes how the message lands.
From you, personally. Connect your Slack account and Pyn sends as you: your name, your photo. The employee sees a DM from their manager or HR partner, not from a bot. If they reply, it comes back to you in Slack. This is the option that makes onboarding feel personal from day one.
From a team persona. Set up a service sender like "People Ops," "L&D Team," or "Your HR Team" and messages come from a consistent, branded voice rather than one person. Great for policies, learning nudges, and moments that shouldn't be attributed to any individual. Available on all paid plans.
From PynBot. For channel announcements, birthday shoutouts, and moments where the broadcast format fits. PynBot can be renamed to match your company. Most employees never know it's Pyn.
DMs and channels
Pyn can send to public Slack channels as well as individual DMs. Use it for team welcome announcements when someone new joins, manager check-in prompts posted to a shared channel, or company-wide moments like work anniversaries and milestone celebrations.
The right message finds the right place.
Built for moments that actually need a response
Some HR communications need to be acknowledged, not just read. Pyn handles that too.
Add a button to any Slack message ("Confirm," "I've read this," "Accept") and Pyn tracks who's clicked. If someone hasn't responded after a set number of days, Pyn sends an automatic reminder. Same message, "Reminder" heading, same timing of day.
You can see response rates across your whole team from inside Pyn. Useful for onboarding tasks, policy acknowledgements, and anything where you need to know it landed.
We're a big Slack culture, so we send Pyn messages through Slack whenever possible. Employees often don't realize the messages are automated — they just see a personal birthday message and get excited.

If an employee responds to an automated message, the conversation continues with the team member we set as the sender, making Pyn invisible to employees — which was a huge selling point.
