JUMBOmail is a free file-sharing service that emphasizes saving users' files with the highest security standards. Through encrypted technology, the uploaded files can only be accessed through a dedicated link. Free accounts can send up to 2 GB of files, and the link will be valid for seven days. If you want to increase the file transfer limit and the link validity period, you can purchase the JUMBOcode upgrade plan. The file limit will be increased to 20 GB, and the link will be valid for six months. In addition to providing secure file-sharing services, JUMBOmail also allows easy sharing of files with others and offers a mail forwarding service to facilitate file delivery.
