1. Use the Correct Customer Service Cover Letter Format

• Set one-inch margins on all sides of the page.

• Choose an elegant font in 11pt to 12pt size. Good CV fonts are perfect for cover letters.

2. Create a Professional Customer Service Advisor Cover Letter Header

• Write your name and contact information first, top corner, right-aligned.
• Include your phone number, email, LinkedIn and optionally, relevant social media handles such as Twitter.
• Put the date below, also right-aligned and use the right format. E.g. 11th March 2025.
• Then left-align and include the addressee’s details. Preferably using the hiring manager’s name.

Can’t find the name of the hiring manager? Check the company’s website, do some research on LinkedIn. If all else fails, call reception and ask. Don’t be self-conscious, it’s worth it. Using a person’s name has a powerful effect.
