Currently, you can set the sender email address in configuration (settings > site configuration > default email address and override at the email address however you CANNOT set the sender name.
If you set the default email address to noreply@company.com, outlook and gmail will display the sender name as noreply, which looks unprofessional and suppresses open rates. At a minimum, allow ability to set at the site config level, but it really should also be option at email list.
Mailgun supports sender name and it would require minimal updates to API request
