Hello {{ subscriber.first_name or "my friend" }},
This is just a short note to communicate my appreciation. Thank you for your helpful responses to last week's email!
In case you missed it, I'm currently writing an ebook on how to start a swim school, and many of you replied with some excellent suggestions to include in the book.
I'm so grateful that you took the time to respond and can't wait to share it with you, which won't be long, since I've almost completed the first draft.
