Marcos F.
Copywriter & Marketing Specialist
I help brands communicate clearly, build stronger connections with their audience, and drive real business results through copy, content, and strategy. My name is Marcos Fonseca. I’m a copywriter, marketing specialist, and SEO writer with over five years of experience working across industries like tech, healthcare, AI, retail, sports, and agriculture. My focus is on helping businesses grow through messaging that feels intentional and aligned with their goals. Most of the clients I work with aren’t just looking for words on a page. They’re looking for a strategic partner who can shape campaigns, define messaging, and make sure every piece of content serves a purpose. I’ve delivered that through projects such as: • Email sequences and campaign calendars, including welcome flows, cart recovery, post-purchase follow-ups, and promotional campaigns • Blog articles and long-form content designed to rank in search and keep readers engaged • Website and landing page copy written with clarity, structure, and conversion in mind • Product pages, collection descriptions, and brand messaging systems built to reflect voice and value • Ad scripts and performance content that work across platforms • Copy audits, rewrites, and strategic updates for brands in growth mode Alongside the writing itself, I’ve managed full email marketing setups inside Klaviyo and HubSpot, developed segmentation logic, and improved inbound performance through smarter, better-targeted content systems. What My Clients Say: “Marcos has been a top professional since day one.” “Hard worker, responsive, and resilient. I’ll definitely have him as a top priority for my next project. The client was very happy with the results and the pace of the delivered work.” “Excellent writing, great communication.” “Marcos was excellent. His writing is fantastic and his communication is prompt. I will definitely work with him again.” “Flexible, efficient, and easy to work with.” “He was attentive to any feedback, very accommodating, and just a pleasant man to work with. Everything was delivered on time and with care.” If you're building something meaningful and need the right words to match, let’s talk.
