Look at integrating with MailLift...
I've been talking to them and they seem to have a great way to send handwritten notes/cards/postcards to prospects

@AndyMorris, this is Brian Curliss from MailLift. Because of how most Zapier connectors handle addresses the better option is a direct integration. Hopefully it will make sense soon for Autopilot to add an integration :)

the zapier integration may fix this.
