The check-in
No offer, no pitch, no discount. One job: prove a human noticed they were gone. This message earns more replies than any other in the sequence, and the warmest ones.
{{first_name}} — I was going back through our records this week and realised it's been a while since we last took care of you.
No pitch here. I'm genuinely curious whether we dropped the ball somewhere, or whether life just got busy. Either answer is useful to me.
If it's the second one, we're still here, and I'd love to have you back in.
Why it works: it asks a question a person can answer in four words. "Just got busy!" is a reply — and a reply is a live conversation you can book from.
