I love that you can write your own message, add pictures or use templates to send out thank-you notes! The handwriting recognition is super easy; however it doesn't always pick up my letters perfectly so sometimes they may not be accurately translated into text in some cases (but this does depend entirely upon how legible/clearly spelled each letter was).
For our business we are trying different ways of getting more people engaged online as well through social media posts but also making sure hand writing remains at least one way for them connect directly via snail mail - which really helps engagement when done right!!
