What we build in Slack
The best notification and approval surface most businesses already own. Also the easiest place to build something everyone mutes within a fortnight, which defeats the purpose entirely.
What it is, and where it sits
Slack is where your team already is, which makes it the natural place for an automation to reach a person. We use it for three things: telling someone something happened, asking someone to approve something, and alerting when something broke.
The engineering here is trivial. The design is not — the difference between a useful Slack integration and an ignored one is entirely about volume and relevance.
What we build in it
- Approval flows with interactive buttons — approve, reject, request changes — writing the decision back to the source system
- Failure alerting from every workflow, with enough context to act on
- New lead and deal notifications routed to the owner, not broadcast to everyone
- Digest summaries replacing per-event noise
- Slash commands for lookups against your systems without leaving Slack
- Escalation when something has waited too long
How it is priced
You already pay for Slack per user. Apps and incoming webhooks cost nothing extra.
The one thing to know: on the free plan, message history is limited, which makes Slack unsuitable as an audit trail. If a decision needs to be evidenced later, write it back to the source system — Slack is the interface, never the record.
When it is the right choice
Slack is the right surface when a person needs to act or know now. It is the wrong surface for anything that needs to be found again later.
- Good: approvals, failure alerts, time-sensitive handoffs, daily digests
- Bad: audit trails, anything requiring a durable record, high-frequency per-event notifications
Limits worth knowing before you commit
- Notification fatigue is the real failure mode. A channel receiving forty messages a day gets muted, and then the alert that mattered is missed. Digest by default; alert individually only when action is needed now.
- Not a system of record. Decisions made in Slack must be written back somewhere durable.
- Rate limits apply to posting, which matters for bulk notification.
- Channel sprawl. One alert channel per workflow is how you end up with thirty channels and no attention.
One channel for failures that need a human, one for approvals, and a daily digest for everything informational. Three channels, all of which stay worth reading.
