I imagine you're wanting to build something like that into your own app rather than using PayPal's? You'd probably need to custom build that if you want your app to have that sort of functionality. You could integrate with Sendgrid or something for inbound email that is addressed to your app to handle it.

Yeah, exactly. I'm working on a project that pays out some of its users monthly (different amounts for each user) and right now we are the thinking the easiest way to do that is via a paypal email address rather than having them go through the stripe sign up process.

Thanks for your response.
