Hi,
With great interest, I am writing in response to your advertisement for the role of Marketing Representative.
Having carefully read the job description, I strongly believe that I have the necessary skills to become a valuable asset for your organization. I had worked as a Marketing Specialist for a previous project which has enabled me to develop excellent marketing, lead generation, administration, and sales conversion. I can work 40 hours per week, willing to work more hours if needed.
Thank you for your time and consideration, and I look forward to speaking with you at your convenience and discuss the application further!
Regards,
Jay
