Aweber recently introduced a new style of hover pop ups that may be just the ticket for you. Take a look at their blog and see how powerful the new feature is.
If you’re not using Aweber yet they have a 30-day trial period, so you can take it for a spin.
If you already use a different Email Service Provider, you can still create your own popups for your web site or blog with this stand-alone Windows application. For the ultimate selection, tracking options, graphics and more in using floating, unlockable popups subscribe to AdImpact
