[{'role': 'user', 'content': "Analyze the following clause from a privacy policy and determine if it's fair or unfair. Also identify any privacy practices mentioned: Email Communications. TripAdvisor wants to make it easy for you to take advantage of travel-related opportunities on our Website. One way we do this is by sending you email messages that contain information about your apparent travel-related interests. For example, if you search for a flight to New York, or New York hotels or reviews on TripAdvisor, we may send you an email message reminding you about special airfare or hotel offers in New York. Similarly, if you receive an email about New York travel and demonstrate an interest in New York hotels, flights, or local travel reviews by affirmatively clicking on a link about New York hotels in the email, you may receive an email about New York hotel or flight offers. We believe these email messages will provide you with useful information about travel-related special offers available through our sites. Please note that you will have the opportunity to choose not to receive these email messages in any such email we send."}, {'role': 'assistant', 'content': 'This clause is fair.
