Service of automatic mailing of congratulations?

Question

Startups

Hello,

over the weekend, an idea was born for a service that will automatically send SMS notifications to a list of friends imported, for example, from social networks. networks.

A random invitation is generated and sent to the user.

Has anyone come across something similar on the web? Perhaps with the implementation not through SMS, but within social messages or email.

Thank you for your attention, have a nice week everyone :)

Answer 1

The idea is good. It's already crossed my mind. I saw the implementation as an additional functionality.
But it seems to me that such a narrow positioning for a service with one opportunity to send congratulations can give its amazing results.

Answer 2

It has long been implemented in many different services as an indirect functionality.
