Subject: Request for Promotion

Dear John,

I hope this email finds you well. I wanted to take a moment to express my sincere gratitude for the opportunities and support you have provided me during my time at the company.

I have been consistently striving to improve my skills and contribute to the company's success. I have taken on additional responsibilities and have been praised for my work by both my colleagues and clients.

With that said, I would like to formally request a promotion to a more senior role. I strongly believe that my hard work, dedication, and ability to take on new challenges would make me an excellent candidate for this opportunity.

I understand that promotions are a significant decision and that there may be many factors to consider. I would be happy to discuss my qualifications and how I can further contribute to the company in a more senior role.

Thank you for your time and consideration. I look forward to the opportunity to further grow my career with the company.

Best regards,
[Your Name]
