This share button is the best comparing to every other button out there. Before, my review I also would like to share with you my experience.
I have used ShareThis, AddThis, AddToAny (being the ugliest), Simple share buttons adder (being the weakest and with the most sarcastic name ever) and I was pretty disappointed with every one of them. Broken links, disruptive aesthetics, lousy support, heavy loading times. So I tried to find something simpler and better. I come across with E-MAILiT and I am fully satisfied by my choice.
E-MAILiT offers the whole package. It's lightweighted, it has very nice and pleasing design. It's very easy to use. It supports even mobile version of my site! Did I forgot to tell you that it allows you to add your banner or ad campaign in order for your visitors to see? That's the best part!
