Unbounce, a service easily create landing pages, has integrated with AWeber, an email service provider.
The purpose of this integration is to have all the subscribers who sign up on your Unbounce page automatically added to your AWeber list.
And Unbouce has kept things simple, so there are just a few steps that you need to do to sync up the two services.
See the AWeber blog for instructions on setting up Unbounce with AWeber.
In addition to this use with AWeber, it’s one of my favorite services, as it enables me to easily build my email lists, as well as automatically create newsletters by generating them from my blog RSS.
