Utilize the drag-and-drop functionality to seamlessly transfer your list from your local drive directly into the designated area indicated by the dotted outline. Alternatively, opt for the ‘Import lists’ option and proceed through the straightforward steps to upload your list.

Upon successful upload, designate your file by selecting it, then initiate the processing by clicking ‘Start List.’ Allow a brief moment for the system to process the data, after which you’ll be able to download a thoroughly verified list. Keep in mind, the processing duration scales with the size of the list, necessitating patience for larger datasets.
