About
userfox is a SaaS product that helps companies improve user retention through welcome, inactivity and custom trigger based emails. We're building a company. Not a product, and certainly not a feature. We believe that making this clear matters. It sets expectations to ourselves and to our customers. We're based in sunny San Francisco, California.
