Hi [first-name],
I see that you recently started using [your-business-name] and I wanted to check in and see if you have any questions.
I’m the founder of [your-business-name] and I’d love to hear any feedback you have on our product. Our development priorities are almost entirely driven by feedback from customers like you, so I would enjoy hearing from you or jumping on the phone some time to chat.
Thanks!
[your-name]
