I recently installed the iPhone version of a social app that was previously iPad only.
In less than a day I got the “welcome to the iPhone version, you want to invite your friends?” email.
It was needy. I’m not inviting them.
Calls to Action are a pain to write. Too passive and they won’t drive people, too pushy and they’ll drive people away. And invariably what works for some won’t work for others. Judging the assertiveness/aggression is tough; but easier is never, ever, sounding needy.
Asking me to invite people within 1 day of installing something feels that.
It might be a considered decision to strike while the iron is hot, but failed; for me, at least.
