It is crucial that an official or corporate e-mail address is established between TM and Supplier as this is the key requirement in supplier registration and the main channel to send 2 separate e-mails on:

1. User ID for Supplier to login to SRM SUS (Supplier Self Service) Portal​​
2. Password for SRM SUS Portal login.

If a prospect supplier does not have any official or corporate e-mail address, the registration process cannot be completed. It is also acceptable if a company use free email provider (except Yahoo Mail and Hotmail) as their official email.
