Make has a growing library of apps, including Handwrytten! However, you can easily integrate non-supported apps through the HTTP/SOAP request tools and the JSON parsers. This flexibility allows you to connect Handwrytten to nearly any other system with an API.
I love that I can connect Handwrytten to Make. It allows me to create handwriting campaigns based on triggered rulesets that would be otherwise difficult to do. The cards truly creating a unique customer experience, thanks to Handwritten and Make.Make User
Using Make, you can use built-in routers to create multiple data flows. Visually build your flows, and create rules when to send handwritten notes.
