While human error is a common source of costly mistakes, unexpected external events can also catch businesses off guard. These include changes in user behavior, sudden spikes in traffic, or unforeseen technical issues. These events, whether positive (e.g., a viral campaign) or negative (e.g., a sudden drop in engagement), require immediate attention to prevent revenue loss or to capitalize on emerging opportunities.

That’s why our Revenue Loss Prevention Notifications don’t just monitor for human mistakes; they also alert you to anomalies in your metrics caused by unexpected events. Whether it’s a problem to fix or a chance to scale, your team will always be prepared to respond.

Real Stories: When Mistakes Slip Through the Cracks

1. A Consent Change Nobody Noticed

One of our clients made a small change to their checkout consent text. Overnight, email signups dropped by 70–90%. The new wording, while legally compliant, wasn’t customer-friendly. It took months before anyone realized what had gone wrong, and by then, thousands of potential subscribers and the associated revenue were lost.

While we can’t share exact figures, we can demonstrate the potential impact of this change using illustrative numbers. If the average subscriber generates €25 over 12 months and you’re losing 1,000 subscribers daily, the revenue loss quickly adds up.

• Daily: 1,000 lost subscribers = €25,000 in annualized value.

• Monthly (30 days): €750,000 in lost potential revenue.

• Annually: €9,125,000 in cumulative impact.

Once again, these figures are illustrative and based on example numbers, not actual data. The actual impact will depend on your subscriber value and the exact loss rate.

These numbers highlight just how significant subscriber churn can be.

How notifications would help: If our system had been in place, the steep drop in signups would have triggered an alert instantly. The team could have spotted the issue and rolled back the change within hours, not months.

2. The Hidden Cost of Simplifying Checkout

Switching from a three-step to a one-step checkout seemed like a smart move. But the change meant customers didn’t opt into newsletters early in the process anymore. As a result, the client experienced a sharp drop in new email subscribers, which went unnoticed for months.

This issue is explored in detail in the article The Hidden Risk of One-Step Checkout.

Let’s use another illustrative example. If the annual value of a subscriber is €13.45 and the business loses 1,400 subscribers daily, the impact becomes significant:

• Daily Loss: 1,400 subscribers = €18,830 in annualized value.

• Monthly (30 days): Nearly €565,000 in missed revenue.

• Annually: A staggering €6.9 million in cumulative impact.

This demonstrates how even a seemingly minor change can snowball into substantial revenue loss if not identified and addressed early.

Note: These figures are illustrative and based on example numbers, not actual data. Actual impact depends on subscriber value and the exact loss rate.

How notifications would help: A sudden drop in email opt-ins would have triggered a warning. The team could have acted quickly to adjust the checkout process, avoiding months of lost subscriber growth.

3. Cart Tracking Gone Wrong

For approximately three months, a client’s cart_update event failed to trigger for half of their customers. This glitch resulted in many cart abandonment emails not being sent, leading to a significant drop in recovered revenue.

While we can’t share exact figures, let’s use an illustrative example:

• Daily Impact: If a brand experienced 7,000 lost cart abandonments per day, and each cart abandonment email was worth €1.50, this equates to €10,500 in lost revenue daily.

• Three-Month Impact: Over three months, this would amount to an estimated €945,000 in lost revenue.

Note: These figures are illustrative and based on example numbers, not actual data.

How notifications would help: With our anomaly detection monitoring in place, the system would have immediately flagged a significant drop in cart_update events. As soon as these events were firing far less frequently than usual, an automated alert would have been sent to the team. This early warning could have enabled the team to identify and resolve the issue right away, preventing months of lost revenue.

In this case, the absence of a notification system meant the problem went undetected for too long, leading to significant financial losses.

Two Types of Notifications to Stay Ahead

Our notification system is designed to solve two critical challenges:

1. Promptly detecting system failures when key processes stop working.

2. Identifying anomalies—both positive and negative—by analyzing daily KPI performance against recent historical trends.
   

1. Real-Time Alerts: When Things Stop Working

Our alert system triggers the moment something critical breaks. It continuously monitors the inflow of key events, and if no events are detected within an expected time frame (e.g., 30 minutes), the system immediately identifies and notifies the responsible person.

Flexible Thresholds

Our system allows you to:

• Set custom thresholds for each event.

• Adjust thresholds for different times of day (e.g., during nighttime, longer intervals for event detection may be acceptable).

What We Classify as Critical Breaks

Critical issues typically involve tracking disruptions or failures in automated campaigns. For example:

• Cart abandonment emails not being sent.

• The checkout process failing to complete.

• Key events like cart_update not firing.

Real-World Example

Imagine no cart abandonment emails are sent for 2 hours. Our system would immediately send an alert via Slack, email, or SMS to your team, enabling you to take swift action and minimize potential losses.

2. Positive and Negative Anomalies

These alerts identify unusual daily anomalies—both positive and negative—in monitored metrics. Thresholds for each metric can be customized individually and adjusted over time (e.g., detecting a 50% deviation above or below the recent historical average).

Example:

• If revenue or traffic drops significantly below the average for a typical Tuesday, you’ll receive an alert to investigate.

• If there’s a sudden spike in conversions, you’ll be notified so you can act quickly and capitalize on the opportunity.

These thresholds and other settigs are stored in a dedicated Bloomreach profile, where they can be easily adjusted. The profile also acts as a logging system for any defined suspicious events that may occur.

Recommended Metrics To Watch For Positive & Negative Anomalies

Drawing on our experience, we’ve identified key metrics worth monitoring. These metrics enable early detection of potential issues and help uncover emerging opportunities.

How Anomalies Are Flagged

Anomalies are identified by comparing yesterday’s metrics to historical averages for the same weekday over a defined period (e.g., the past eight Mondays). This approach accounts for normal fluctuations, such as seasonality or weekday-specific patterns, ensuring a baseline that is both accurate and relevant.

• Positive anomalies are flagged when a metric significantly exceeds its average—say, by more than 50%—highlighting opportunities like a surge in traffic or conversions.

• Negative anomalies occur when values fall below expectations, helping you quickly identify and address potential issues.

This method equips you with timely, actionable insights, allowing you to resolve problems promptly or capitalize on emerging opportunities with confidence.

Flexible & Transparent

Our system is designed to seamlessly integrate into your team’s daily workflows while providing full visibility and control.

• Seamless Integration: Notifications are sent directly to the tools your team uses every day, including Slack, Microsoft Teams, email, or SMS for urgent situations.

• Centralized Logging System: All notifications are archived in a dedicated Bloomreach profile, offering a transparent record of anomalies. This allows you to monitor trends, revisit past incidents, and identify opportunities for improvement.

Detailed Insights: Each alert includes direct access to comprehensive reports, providing clarity on what happened and why, enabling swift, informed decisions. For instance, in the example below, sessions are broken down by day and traffic source. This allows you to quickly determine whether a traffic anomaly—positive or negative—stems from a specific traffic source or is spread evenly across all sources.

Techstack Flexibility

While the system is designed to integrate seamlessly with Bloomreach Engagement, it’s not limited to this platform. Similar configurations can be implemented using tools like BigQuery and Cloud Functions—a setup we’ve successfully deployed—ensuring adaptability to any technology stack.

Human Errors and Unexpected Events Happen. Identify & Fix Them Before They Cost You Big.
