Can you still have an iMessage with someone who doesn't have an iPhone?

This friend of mine used to have an iPhone, but now he doesn't. However when I go to text him, it still says iMessage even though it's not one. So I'm worried that if I text him he won't get it

No. You can't text over imessage if that person does not have an IPhone. Hope i've helped will you answer my question now.

No is only for iphones

No.iMessages are only for Apple products. (Macs with the app installed, iPhones, iPads, iPod touches).
