Hi, I’m Alexander Kehl.
For the last 30 years, I’ve worn a lot of hats – consultant at Ernst & Young and PwC, founder of an edtech startup, and entrepreneur running my own advisory business.
But the common thread through it all?
Marketing. Online. Always.
No matter what I was building or who I was helping, I kept coming back to one thing: the power of online marketing to create real results. Especially email marketing. That’s where the magic happens—where relationships turn into revenue.
I started this blog to share the most valuable, real-world advice I’ve learned (and tested) about growing your list, writing emails that sell, and building smart funnels that work while you sleep.
Whether you’re launching your first side hustle, scaling a freelance business, or building a course empire—my goal is to help you master email marketing and turn it into your most powerful asset.
Thanks for stopping by. I’m glad you’re here.
