The Hidden Cost of Using Power Automate as a Replacement for SharePoint Alerts
Over the past several months, we’ve seen a growing trend in forums, Reddit threads, and customer conversations:
“Why not just use Power Automate instead of SharePoint Alerts?”
On the surface, it sounds reasonable. Power Automate is included in most Microsoft 365 licenses, it’s flexible, and—most importantly—it feels free.
But when you dig deeper, the reality is very different.
Let’s break down the true cost of using Power Automate as a 1:1 replacement for SharePoint Alerts—and why that approach can quickly become expensive, complex, and unsustainable.
The Myth of “Free” Power Automate
Yes, Power Automate is included in many M365 plans.
But what’s often misunderstood is that it operates on a consumption-based model behind the scenes.
Every time a flow runs, you’re consuming:
- API calls
- Trigger executions
- Actions within the flow
These are not unlimited.
Microsoft enforces request limits per user per month, and once you exceed those limits, you’re either:
- throttled (flows slow down or fail), or
- forced into premium licensing
The Real Problem: Scale
Power Automate works great… until you scale it.
Let’s take a common use case:
“Send me alerts when items change in a SharePoint list.”
Now imagine:
- A list with 5,000–20,000 items
- Multiple users needing alerts
- Frequent updates (status changes, edits, metadata updates)
Most Power Automate solutions for this involve:
- Scheduled flows (every 5–15 minutes), or
- Trigger-based flows that evaluate changes
What happens next?
Each run of the flow may:
- Query the entire list (or large portions of it)
- Loop through items
- Compare changes
- Send notifications
That’s hundreds or thousands of actions per run.
Multiply that by:
- Runs per hour
- Hours per day
- Days per month
You can very quickly burn through your monthly request limits.
A Simple Cost Scenario
Let’s say:
- A flow runs every 15 minutes → 96 runs/day
- Each run processes 1,000 items → 1,000+ actions
- That’s roughly 96,000 actions per day
Over a month:
~2.8 million actions
Even with generous licensing, that’s pushing limits—and likely exceeding them.
Now multiply that across:
- Multiple lists
- Multiple departments
- Multiple flows
At that point, Power Automate is no longer “free.”
Power Automate Is a Great Tool—But Not for This
To be clear:
Power Automate is excellent for:
- Workflow automation
- Integrations
- Approvals
- Event-driven processes
But using it as a direct replacement for SharePoint Alerts is forcing the wrong tool into the wrong job.
The Hidden Operational Costs
Beyond licensing, there’s another cost most organizations overlook:
1. Flow Sprawl
Instead of a centralized alerting system, you end up with:
- One flow per list
- Variations per use case
- Duplicate logic across flows
This creates:
- Inconsistency
- Redundancy
- Governance challenges
2. Maintenance Overhead
Flows don’t maintain themselves.
You need to:
- Update them when lists change
- Fix broken connections
- Adjust logic when business rules evolve
- Monitor failures and retries
3. Skill Dependency
Power Automate requires:
- Someone to design flows properly
- Someone to troubleshoot issues
- Someone who understands performance implications
This often turns into:
- IT dependency, or
- Reliance on a “power user” bottleneck
Why SharePoint Alerts Existed in the First Place
SharePoint Alerts were designed to:
- Efficiently track changes
- Notify users without scanning entire lists
- Scale across large datasets
They are event-driven and optimized, not brute-force.
Trying to replicate that with Power Automate often means:
- Rebuilding logic inefficiently
- Paying in performance and consumption
The Case for Alert Plus
This is exactly why we built Alert Plus.
It provides:
- True SharePoint alerting functionality
- Scalable performance—even with large lists
- Centralized management
- Advanced filtering and targeting
- No hidden consumption costs
And importantly:
No need to build, monitor, or maintain dozens of flows
The Bottom Line
Power Automate may look like a free alternative—but when you factor in:
- Consumption limits
- Scaling challenges
- Maintenance overhead
- Administrative complexity
…it becomes clear that the real cost is much higher than expected.
If you’re looking for a reliable, scalable, and purpose-built solution for SharePoint alerting:
Alert Plus is the right tool for the job.
