What is the best item to sell to freelancers and marketers in your experience? I'm not looking for spoon-feeding. I know I need to test but I'm just looking for input from people that have worked with this niche. I'm new to email marketing. I wrote a bot that legally allows me to collect thousands of email subscribers a day. This isn't a sales pitch either. I will never sell it. Once I'm finished with it, I'll share it on here. I don't expect it to last long after that however. Anyway, ya ... Gonna have a crazy amount of emails and I want to use them well so, any product recommendations?
