I'm assuming here that you are interested in making money online and already have an autoresponder service.
The thing is that most people, not you of course, just dabble with their online activity and just don't do enough to actually get any traction and therefore also don't make any money other than accidentally.
One of the things which cause problems for new people to list building is twofold.
The first is that they struggle to come up with a good lead magnet to offer people who visit their landing page and then they struggle to convert those people to an offer which can make them money.
I'm going to put a couple of things in front of you here which just might make the difference for you.
Firstly I'm going to suggest you visit this site, Everything Rebrandable, and take advantage of their $1 trial offer while it's still available.
This site has lead magnets you can give away which have a way built in for you to make a passive income just from that if that's all you do but you can work a bit harder at this and build a bigger passive income by promoting the site a bit harder.
The other thing is one you might have already seen but you may not have.
It's a page on this site with an offer that you might find interesting. Go to this page to check it out. How to make thousands selling someone else's product it's a simple bit of training that you can get access to.
Any way, have a look at those and let me know what you think.
