I found out about e-mailit some time ago, and I was stunned. I loved immediately its philosophy, and found really useful the tips that guided me on the installation/screenshots tab.
After some serious examination of its features, I decided to use it in my website. Best decision I ever made.
I got rid of my previous sharing buttons (sorry!) and replaced everything with e-mailit. E-mailit loads much faster, has a perfect design and doesn't "spoil" the feel of my website. The ad is there for anyone interested to see, or you can simply hide it! It's that easy!
I love that it works with no cookies whatsoever! Finally, the thing that interests me the most, is the upcoming version of e-mailit for mobiles. That would really complete the whole picture.
