To quickly fill all the blanks in the "subject line" column, you can use the "Write to Other Table" feature in Clay. Here's how:
1. Right-click on the "subject line" column.
2. Select "Edit Column" > "Select Data Type".
3. Choose the appropriate data type for your subject lines.
4. Click "Save Settings".
5. Use the "Write to Other Table" feature to populate the blank cells with your desired subject line content.
This method allows you to efficiently fill multiple blank cells at once. If you need more detailed guidance on using "Write to Other Table", let me know and I'll provide further instructions.
