We support file submissions in .csv format.

For seamless processing, ensure your file contains a single column dedicated to email addresses. 

While the header can be labelled anything, we recommend including a clear and properly formatted header row in your CSV for better organization. Alfred will return the original rows and the newly appended data fields to your returned file, as described in How will my results be returned?.

For optimal results, we suggest using .csv format—it’s our preferred option for simplicity, efficiency, and ease of use!
