Change address in From Field

I’m currently using the free version to see if fits our company’s needs, we are using Google Workspace, but I have the need to change the From field to a different email. Is not an alias or a delegated account, this is -sending on behalf of-. Is there a way to get this done? I need to explore all our requirements before jumping to buy licenses.

Unfortunately it is not possible to change the From address manually while composing the message.

You will need to either setup an account for that address, or have the address included as an alias (provided the server supports it) for your existing account.
