AutoLetter provides comprehensive statistics for each campaign. In the Analytics tab of your campaign detail view, you'll find all the key metrics and charts to evaluate the performance of your mail campaign.
At the top of the statistics page, you'll find four cards with the most important metrics:
Shows the revenue generated by the campaign and the Return on Investment (ROI). The ROI is calculated from the ratio of revenue to campaign costs and tells you at a glance whether your campaign is profitable.
The conversion rate shows the percentage of recipients who placed an order after receiving the letter. It's displayed as a percentage value.
The total number of letters sent in this campaign so far. Here you can see how many recipients were actually reached.
Shows the total amount spent on printing and shipping so far -- relative to the set total budget.
Below the metric cards, you'll find several interactive charts:
A timeline chart that visualizes daily sending activity. You can see at a glance which days had particularly high letter volumes and whether there are patterns (e.g., weekend pauses, peaks after promotions).
Shows budget usage over time. You can see how quickly the budget is being consumed and whether the daily budget is regularly exhausted. Useful for planning budget adjustments.
The conversion chart shows how the response rate develops over time. This lets you spot trends -- is the conversion rate rising, staying stable, or declining?
A bar or pie chart that breaks down the status of all sent letters:
| Status | Meaning |
|---|---|
| In production | Letter is being printed |
| Shipped | Letter has been handed off to DHL |
| Delivered | Letter has been delivered |
| Failed | Delivery was not possible |
Conversion data typically takes 2 to 4 weeks before meaningful results are available. During this time, letters reach recipients and they have the opportunity to place an order. Therefore, don't evaluate the conversion rate too early.
High ROI, low conversion rate: The few conversions are particularly valuable (high cart values). Check whether you can expand the target audience.
Low ROI, high conversion rate: Many customers order, but with small cart values. Consider whether you can promote higher-value products or adjust the minimum order value.
Declining activity: The budget may be exhausted or the target audience depleted. Check the Budget tab.
