These are my best affiliate programs that I use as an email marketer and do earn a commision when I recommend them to my mailing list:
ClickMagick is the most powerful, easiest to use and straightforward; tracking tool on the market. Clickmagick is used as the way for you to monitor what kind of traffic you are getting. For instance, with solo ads, you can’t always go by what the seller tells you.
Moolavine is program where you can affiliate your Clickbank or JVzoo links, every time you make sales you get paid from those networks so you don't need to go after people to sell products because the program makes people to chase you to buy the respective products.
Getresponse is an effective email marketing platform which is also affiliate friendly when promoting your affiliate links. This auto-responder allows you to stay in touch with your customers; a real estate for entrepreneurs.
