About me
Hello I'm Jason, I help creators, founders, and brands build newsletter systems that do more than just send emails they drive real audience growth and engagement.
Many newsletters struggle because the foundation is rushed, with weak onboarding, disorganized lists, and no clear structure.
I specialize in setting up Beehiiv, ConvertKit, Substack, Brevo and Ghost with clean systems and strategic workflows. My focus is creating a smooth subscriber experience from day one.
If you want a newsletter that looks professional, feels intentional, and is built to scale, you're in the right place.

Jan 2026 - Present • 8 mos
As an Email Marketing Specialist, I helped clients design and manage newsletter systems on platforms like Beehiiv, ConvertKit, Substack, brevo and Ghost. My work focused on email marketing strategy, subscriber list management, welcome sequences, campaign automation, and audience growth. I worked closely with creators and small business owners to turn scattered email efforts into structured, scalable newsletter systems, handling platform setup, list segmentation, and performance tracking to boost open rates and engagement. This experience shaped my approach on Fiverr today: building newsletter systems that are not just functional, but strategically designed to grow your audience and revenue. Ready to turn your newsletter into a real growth engine? Message me today and let's build a system that works as hard as you do.
