Not too surprising the lowest converting of all was the classic sidebar signup.
I have to mention this was all done with free traffic.
Today the majority of websites are using popups. It simply is the no. 1 way to build your list. Lately I've been seeing more and more full page overlays and they look awesome.
The trouble is: there have been so many plugins and generators on the market. I bought several and they all have some specific feature I like, but there's always something missing too. I'm not implying that the new EZpopups is perfect, but I like what I see. A lot.
This new generator by Sean Donahue is the first of it's kind. It comes with a drag and drop builder and you can do just about anything with it. Complete design freedom is yours. You can use it for popups, slide-ins, overlays, coupons and more.
This thing integrates with all the major autoresponders, crm's, shopify, you name it.
You can funnel your subscribers to multiple lists at once.
With the targeting feature you can show different popups for different sections of your site, you can split test the crap out of your popups to get the best conversion rates, and if for some reason you only want your popup to show to people coming from Facebook because you hate them Twittereens, that's no problem at all.
Did I mention this comes with a drag and drop builder? I have Profit Builder and it took me a while to get used to but now it's like my smartphone, can't do without. So if you're in the market for a truly versatile tool, check it out.
