When it comes to segmenting your data in Salesforce Marketing Cloud (SFMC), you have two powerful tools for Segmentation: Data Filters and SQL Queries. Both methods allow you to create targeted segments of subscribers, but they differ significantly in complexity, flexibility, and use cases. Let’s explore these two approaches in detail.
What is a Data Filter?
A Data Filter in SFMC is a set of criteria used to segment a subscriber list or data extension. It's an intuitive, user-friendly way to create segments without needing technical skills. Data Filters can be created using Profile Attributes, Preference Attributes, or specific data from Data Extensions.
Types of Data Filters:
1. Profile-Based Filters:
Profile Attributes: Characteristics like age, gender, location, etc., associated with a subscriber's profile.
Preference Attributes: Subscriber preferences, excluding preferences like HTML email format.
2. Data Extension-Based Filters:
You can segment data stored in Data Extensions by filtering on specific fields. This is done in the Email Studio under the ‘Subscribers’ section by selecting ‘Data Filters.’
Creating a Data Filter:
Choose the data type (Profile or Data Extension).
Define the criteria by selecting attributes, operators (like “IS GREATER THAN”), and values.
Example: To segment subscribers over the age of 20, set the profile attribute to AGE, the operator to IS GREATER THAN, and the value to 20.
Data Filters are ideal for marketers who need a quick, easy way to segment lists based on straightforward criteria.
What is a SQL Query?
For more advanced segmentation, SQL Queries are the way to go. SQL (Structured Query Language) offers greater flexibility and control, allowing you to perform complex data manipulations and segmentations across multiple Data Extensions.
Creating a SQL Query:
SELECT the fields you want to include in your target Data Extension (DE).
WHERE clause to define your criteria. For example, filter only on subscribers marked as ‘prospect’ in a field.
Use logical operators like AND, OR, and NOT to combine multiple criteria.
FROM specifies the Data Extension you’re pulling data from.
Validate your query to ensure there are no syntax errors.
Joining Multiple Data Extensions:
INNER JOIN: Returns records with matching values in both tables.
LEFT JOIN: Returns all records from the left table and matched records from the right table.
RIGHT JOIN: Returns all records from the right table and matched records from the left table.
FULL JOIN: Returns all records with a match in either table.
Data Saving Options:
Appending: Add new data to the target DE without altering existing data.
Updating: Modify existing records or add new ones if they don't exist.
Overwriting: Replace all current data in the target DE with the new data.
SQL Queries are best suited for users with technical expertise who need to perform detailed and complex data segmentation, often involving multiple Data Extensions.
When to Use Data Filters vs. SQL Queries?
Use Data Filters when:
You need to create basic segments quickly.
You’re working with profile attributes or simple Data Extension fields.
You don’t have advanced SQL knowledge.
Use SQL Queries when:
You need advanced segmentation.
You’re working with multiple Data Extensions.
You require complex logic and relationships between data sets.
Conclusion
Both Data Filters and SQL Queries are essential tools in Salesforce Marketing Cloud, each catering to different needs and expertise levels. Data Filters provide a simple, straightforward way to segment your lists, making them perfect for quick tasks. SQL Queries, on the other hand, offer the depth and flexibility needed for more complex segmentation scenarios. Understanding when and how to use each will empower you to leverage your data to its fullest potential in SFMC.
