Jennifer Lumley

Customer Service Manager
Severance Sourcing Inc.
17 Aston Street



Dear Ms Lumley,

As a genuine admirer of Severance’s peerless online customer service offering, I was excited to see the opening for a customer service advisor at your London headquarters. With my 5+ years of experience and fluent French language skills, I am confident I can contribute my skills to Severance as it expands its offering to France-based clients.


I am aware that a key objective moving forward will be reducing call waiting times. While working at Liston Partners, I’ve noticed that shift patterns were not matching peak customer demand. By working with our IT team to produce data on call waiting times I helped our senior manager readjust staffing levels to reduce average waiting times by five minutes. This was directly cited by customers in call satisfaction feedback which surged from a score of 60% to 85% in a matter of months.


I am sure that my track record of resolving 95% of complaints at first point of contact will help Severance to achieve its aim of constantly improving complaints resolution metrics. I’d be delighted to have the opportunity to further my professional growth in an environment such as Severance, whose reputation for comprehensive staff training is legendary in the industry.


Thank you kindly for your time and I’m available on the telephone number above to discuss this opportunity at your convenience.


Yours sincerely,

Mark Sanders

Customer Service Cover Letter Template


Here’s how to write a customer service cover letter for your job application:


1. Use the Correct Customer Service Cover Letter Format


  • Set one-inch margins on all sides of the page.
  • Use single or 1.15 line spacing for the best cover letter format.
  • 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 2020.
  • 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.
