I get request a lot by my clients about one key feature we have in our appointment reminders, and that is a custom reminder picture we send out with their name on it. By adding this type of custom stuff to our reminder it has set us up to stand out and has increased our show up rate by 16% overall this past year. The site you can get this is niftyimages.com and its free for the first 10,000 opens. I'm not affiliated at all and I don't get anything from this, just value to add to your tech stack. When your done all you have to do is place the url they give you into the URL spot in you text workflow and your done. This was a slow year for me with New AI implementation but still 1000 appointments booked.
We add this as an upsell at $20/m...
