Putting Email Subscription button in the Homepage along with all the other pages in my site, is it really a good idea? It is more like of a pop-up.
Whatever works for you mate. But make sure if they ignore it once than no pop-up jumps to their screens on that entire session otherwise they can feel uncomfortable.
Putting email subscription button in the homepage is good along with the additional pages. But it is wise only if it is a permanent one. If the button is a pop-up then I think once at the landing page is enough.
We are not just putting email subscription button in the home page without an interesting text that composed of benefit in which will attract the users to subscribe.
It would be better if you do so with a pop up having attractive offers related to your niche or website or your own products.
