Determining whether your email is creepy can be subjective, but there are a few questions you can ask yourself:
Did the recipient explicitly share this information with me? Would I feel comfortable receiving this email if I were in their shoes? Is the personalization enhancing the user experience, or is it just showing off? Does the email respect the recipient's privacy and boundaries?
If you answer "no" to any of these questions, it's time to rethink your strategy.
