Freshdesk has the option to include the Agent's name in the sender information of emails sent out of your Freshdesk Account. However, if you would like your Helpdesk's name or company name to be used instead, you would have to make a change to the email configuration.

Navigate to Admin > Channels > Email > Advanced Settings and toggle off 'Use agent names in ticket replies and outbound emails'. This would ensure that the emails are sent with the name of your support email address, which would be available at the "Name" field under Admin > Channels > Email > Edit (corresponding to the support email address).
