## Understanding Delpha’s 6 Data Quality Dimensions for Email

Delpha evaluates each field using **6 key data quality dimensions**. Below is how each dimension applies to **email fields**, helping users interpret scores and drive cleanup efforts.

## Data Quality Dimensions Explained

### **Completeness**

> **Question:** Do I have an email?

* If no email is present, this dimension will be marked as incomplete.

### **Validity**

> **Question:** Is the email address safe and valid?

* Delpha checks if the email can safely be used.
* ⚠️ **Depends on Completeness**:
  * If the email is **incomplete**, then:
    * **Validity** = `Invalid`
    * **Qualification** = `Invalid`

Sending to it will result in a hard bounce or damage your sender reputation.</td></tr></tbody></table>

### **Uniqueness**

> **Question:** Is the email unique in your Salesforce database?

* Duplicate email addresses across contacts may flag this dimension as problematic.

### **Consistency**

> **Question:** Does the domain of the email match the company email domain?

* Validates that the contact’s email domain matches the primary domain of the linked Account record.
* ⚠️ **Depends on Completeness**:
  * If the email is incomplete → **Consistency** = `False`

### **Accuracy**

> **Question:** Does the email match expected patterns with a high confidence score?

* Based on Delpha’s AI model and pattern matching logic.
* ⚠️ **Depends on Completeness and Validity**:
  * If the email is incomplete or invalid → **Accuracy** = `No`

### **Timeliness**

> **Question:** Is the email still active or in use?

* Measured by whether an email has been received from this address in the **last 30 days**.
* Helps determine if the contact data is still current.
