What is the format of the file I can upload for the My Custom Alerts feature?

My Custom Alerts accept CSV files formated in UTF 8 format.



Below are examples of files you can look at to structure your files.

The My Custom Alerts feature will only use the 1st 5,000 rows of the CSV file you upload. If you need to upload a list with more than 5,000 brands please split up the file using software or service such as https://www.splitcsv.com/ or https://filesplit.org/ to split the file into 5,000 lines or small. Then upload one file after the other to get all your custom alerts uploaded.
