### **Connector Workflow Guidelines**

1. **File Format Considerations:**
   * The Email Attachment Connector will only process files with `contentType` and extension in CSV format. No notifications will be sent for files that do not meet this criteria.
2. **Attachment File Handling:**
   * Please ensure that you do not send any empty files, as attempting to send such attachments may result in errors.
   * The connector processes file data normally while skipping empty lines.
   * Data corresponding to null value columns will not be processed.
3. **Empty Columns:**
   * In cases where all rows are processed, but there are no columns, no data will be processed.
4. **Data Type Handling:**
   * All garbage values will be processed as strings.
5. **Header Assumption:**
   * By default, the first line of your attachment is considered a header. Please do not include nulls or empty values in this first line.
6. **File Size Limit:**
   * Daton will skip processing any attachment that exceeds 5 MB in size.
7. **Regular Expression Testing:**
   * You can test regular expressions on this site: [Regex Testing Site](https://regexr.com).

Please follow these best practices to optimize your data integration workflow.
