I send weekly articles on self-motivation (self-improvement) niche. I have 350+ subscribers and I generate 0-10 leads/day and my landing page is Your Way to Success
. But, I have not generated a single penny till now. Can anybody tell me whether email marketing and self-improvement is profitable or not? or Should I stop working and wasting time in this niche? Please suggest some improvement in my landing page and the way I should work.
