Sender name needs to be a token attribute field. This will allow us to create templates that say "Hi {{{firstName}}}, this is {{{senderName}}} reaching out regarding {{{issue}}}" Contact owner field is not appropriate as a replacement for any use case where multiple agents with distinct identities need to be communicating with a customer. For example, in a B2B context, the contact owner could be the account executive. But a SDR could also be reaching out to schedule follow ups, a support engineer could be reaching out to talk about engineering issues, and product might even jump in to ask for feedback.
