As an Accounts Receivable Supervisor in hospitality, I struggled with writing formal emails due to my basic English skills. Feedback from my boss suggested my informal style might deter clients, making payment follow-ups challenging. To boost efficiency, I enrolled in a ChatGPT course for email writing. It taught me to use prompts like 'create an email' for formal responses and input thoughts for better email composition. Since completing the course, my emails are more effective, leading to increased client responses. This improvement earned me compliments from my boss, a positive performance appraisal, and a significant pay increase.
