I'm looking for sending email using SendGrid whereas my From email address would be a Team Id or Distribution list. But in the Send grid portal I can only authenticate single mail address. Is there any way to achieve this
If you set up domain authentication, you can configure your "From" address to be from any email on the authenticated domain.

If you need to use single sender verification, that process requires that you (or someone acting on your behalf) have access to the address to complete the verification by clicking on the sent link. In the case of a distribution list email address, this in theory should be able to be done by anybody on the distribution list receiving the email, but everyone will see the verification request.
