Overview
Handwrytten
Handwrytten helps you scale the personal touch of a handwritten note without picking up a pen. By using custom-designed robots that hold real pilot G2 pens, the platform transforms your digital text into physical mail that looks and feels authentic. You can choose from dozens of handwriting styles or even have your own handwriting digitized for a truly personal signature on every piece of mail you send.
Whether you are thanking a customer for a purchase, following up on a sales lead, or sending holiday cards to your entire database, you can automate the process entirely. The platform integrates directly with your existing tools like Salesforce and HubSpot, allowing you to trigger physical mail based on digital actions. It is an ideal solution for sales teams, real-estate agents, and non-profits who want to stand out in a crowded digital inbox.
