Email address where the email will be sent. Options:

• Send to email - to the specified address.
• Send to client - to the address(-es) extracted from contact details stored in the PNR (email field only or using SSR CTCE as fallback if email field is missing).
• Send to agent - to the address determined based on the "Agents" setting of the #OFFICE_LINK# to which the processed PNR belongs (fallback address should be specified in case the agent's address cannot be determined).
