What this template solves

  • Prevents surprise overages by warning users before they hit hard limits.
  • Routes critical thresholds to high-attention channels like SMS.
  • Gives SaaS products a standard pattern for quota and usage monitoring alerts.
  • Reduces support tickets from users who didn't know they were approaching a limit.

When to use this template

Use this template when:

  • Your product has metered usage (API calls, storage, seats, credits).
  • You need different notification strategies for warning vs. critical thresholds.
  • Users should be able to choose which channels receive threshold alerts.
  • You want to proactively drive upgrades before limits are exceeded.

How it works (step-by-step)

  1. Trigger. Your system detects a usage metric crossing a configured threshold (e.g., 80% or 100%).
  2. Evaluate severity. Pass warning or critical in the trigger payload based on the threshold level.
  3. Route by severity. Warning alerts send email only; critical alerts send email and SMS.
  4. Respect channel preferences. Only send to channels listed in data.threshold.channels.

Best practices

  • Use two tiers. Warning at 80% and critical at 95–100% gives users time to act.
  • Include context. Always name the metric, current percentage, and what happens at 100%.
  • Link to action. Point users to upgrade, reduce usage, or view their dashboard.
  • Throttle repeats. Don't re-fire the same threshold alert on every API call.

Common mistakes to avoid

  • Alerting too late. By the time users hit 100%, it's often too late to prevent disruption.
  • Same channel for all severities. Critical limits deserve SMS or push, not just email.
  • Missing units. "You've used 80%" is less useful than "You've used 8,000 of 10,000 API calls."

FAQ

What metrics should I alert on?
Start with the limits that cause the most pain: API quotas, storage, seat counts, and billing thresholds.

Should I alert on every threshold crossing?
No. Alert once per threshold tier per billing period, then reset when usage drops or the period renews.

How do I handle team accounts?
Notify account admins and optionally individual users who contribute most to usage.
