email delivery service

Hi Team,

We are planning to use OCI email delivery service to send emails. We have a query regarding the email domain and approved sender address.

We have 3 public domains which we have got from third party vendor for our external applications.

Can we use any domain?

We understand we have to create approved sender email address in OCI approved senders.

Can we create the sender email address with any name? is there any restriction to this?

Do we need to create the same sender mail address any where else from customer end?

Thanks,

SGU
