In addition to quick filters, AutoLetter offers advanced filters that let you define your target audience based on specific metrics and operators. This way, you reach exactly the customers who are relevant to your campaign.
Advanced filters allow you to filter by the following metrics:
| Filter Criterion | Description | Example |
|---|---|---|
| Order count | Number of orders a customer has placed | Customers with more than 3 orders |
| Customer Lifetime Value (CLV) | Total value of all orders by a customer | Customers with CLV over 500 EUR |
| Average order value | Mean value per order | Customers with an average over 80 EUR |
| Total order value | Sum of all orders | Customers with a total over 200 EUR |
For each filter, various operators are available to precisely define the condition:
| Operator | Description | Applicable to |
|---|---|---|
| Contains | Value contains the search term | Text fields |
| Does not contain | Value does not contain the search term | Text fields |
| Starts with | Value starts with the search term | Text fields |
| Ends with | Value ends with the search term | Text fields |
| Equals | Value matches exactly | Text and number fields |
| Does not equal | Value does not match |
Start creating a campaign or edit an existing one. Navigate to Step 2 (Target Audience).
Below the quick filters, you'll find the Advanced Filters section. Click Add Filter.
Select the desired criterion from the dropdown list -- e.g., "Order count."
Choose the appropriate operator -- e.g., "Greater than."
You can use quick filters and advanced filters simultaneously. Both filter levels are combined with each other (AND condition):
Example: All repeat buyers with a CLV over 200 EUR
Result: Only customers who have ordered multiple times AND whose total value exceeds 200 EUR.
Use the combination of quick and advanced filters to create high-value customer segments. For example: Repeat buyers with a high average order value are particularly receptive to premium offers.
The recipient count updates in real time whenever you change a filter. This lets you immediately see how your filter adjustments affect the target audience size.
You can remove any individual advanced filter using the X icon next to the filter. To remove all advanced filters at once, click Reset All Filters.
| Text and number fields |
| Greater than | Value is greater than | Number fields |
| Less than | Value is less than | Number fields |
Enter the comparison value -- e.g., "3."
Repeat the process to add more filter criteria. All filters are combined with an AND condition.
