Dear Hiring Manager, I am excited to apply for a Social Media Manager position at your company. With three years of hands-on experience managing client portfolios at digital marketing agencies in Athens, I have developed a genuine passion for building lasting client relationships and delivering campaigns that make a real impact. I thrive in fast-paced environments where I can combine strategic thinking with day-to-day execution, and I am eager to bring that energy to a new team. In my current role as Account Manager at Advengers, I oversee a diverse portfolio of clients, including E.J. Papadopoulos S.A., and Praktiker Hellas, managing everything from creative briefs and campaign execution to budgets and performance reporting. I coordinate closely with Creative, Performance, and Production teams to ensure every deliverable meets the highest standards before it reaches the client. I also mentor junior Account Executives, which has sharpened my leadership skills and deepened my understanding of what it takes to keep a team aligned and motivated. Prior to this, at Socialab, I honed my project management skills working with well-known brands such as Interamerican, L'OR Espresso, and Holmes Place Greece. Handling daily client communications, managing timelines across concurrent projects, and producing performance reports gave me a solid foundation in the end-to-end client journey. I also gained practical experience in email marketing, social media management, and content creation, skills that help me speak the same language as the teams I collaborate with. I hold an MBA from the University of Piraeus, a BA in Political Science from the National and Kapodistrian University of Athens, and a Digital Marketing certification from the Athens University of Economics and Business. I am fluent in English and have a good command of both German and French, which allows me to work confidently in international settings. I would love the opportunity to discuss how my background and enthusiasm for client success could be a great fit for your team. Thank you sincerely for taking the time to read my application, I hope to hear from you soon. Warm regards, Stefania Vitzilaiou
