How I built automated reminders into a Slack approval tool with zero coding experience

When I started building TeamAutomation, I thought the hardest part would be the Slack integration.
It wasn't.
The hardest part was figuring out what happens when someone just... doesn't respond.
You send an approval request. The other person is busy. They forget. The request sits there for 3 days. Meanwhile the person who sent it has no idea if it was seen, ignored, or lost.
That's the problem I needed to solve. Automated nudges.
Here's how it works in TeamAutomation:
Day 1 — If no response after 24 hours, the approver gets a reminder in Slack.
Day 3 — Still no response? Another nudge, slightly more urgent.
Day 7 — Final reminder before the request expires.
The tool I used for this is called Inngest — it handles background jobs and scheduled functions. As a non-technical founder, I didn't build this from scratch. I worked with AI tools to implement it step by step.
But the logic behind it? That came from just thinking about the real problem.
Most approvals don't fail because people are lazy. They fail because there's no follow-up system. Email gets buried. Slack messages scroll away. Nobody chases.
Automated nudges fix that without making anyone feel micromanaged.
If you're building something similar — start with the failure case. What happens when nothing happens? Build for that first.
Still at 0 users, but the system works. Onward.
