This welcome email from TourRadar has a solid foundation. The subject line is inviting, and the preheader gives a quick glimpse of what's to come. The friendly tone connects well with travel lovers, making it relatable. However, it could be sharper. The introduction is a bit lengthy; a concise version would keep readers engaged. The section explaining “organized adventures” could be clearer and more enticing by highlighting unique experiences. Lastly, adding a strong call to action at the end can encourage immediate exploration. Overall, it’s a good start, but refining the copy and structure will boost its impact!
