Some initial questions:
–how involved in her life have you been up til now? There are godfathers, and then there are godfathers… It is possible that you have had regular, ongoing discussions about the sacraments & living a Catholic life; it is also possible that this is the first time she is hearing your opinion on such matters.
–Why did you choose to email & not give her a call, a the very least, or make a lunch date to stay in contact? I ask b/c I have seen in my own circle of family and friends not only how helpful email has been for staying in touch with each other but ALSO how destructive and hurtful it has been when people substitute it for discussions that would be much better received in person or over the phone, even if they would be more difficult to initiate.
Whatever your answers are, I think I would suggest that you give her a call & say, “Sweetie, I was thinking about the email I sent you & really wanted to follow up in person. Can we chat?” You’ve seen, I’m sure, in your time on CAF how twisted and misunderstood topics can become, due entirely to their complexity, the state of mind of the writer, the reader, and the word choice.
(Just for clarity, this is all written with an encouraging, friendly tone! )
