Importance of cover letters in the United Kingdom

Cover letters are a vital part of professional job applications, helping shape recruiters' first impression of your profile.

Here’s why they’re important:

  • Indicates your genuine interest: A well-researched cover letter reflects your knowledge of the company and role.
  • Professionalism from the outset: Employers expect your cover letter to be structured, polite, and formal. If you wish to add a more personalised touch, be sure to address your recipient directly.
  • Capture the recruiters' attention: For most roles, candidates tend to have rather similar experience, which is why you should use your cover letter to explain what is unique about your profile.

What UK employers expect from a cover letter

Want to make an excellent first impression on your UK employers with your cover letter?

Here are three handy tips and tricks to keep in mind when creating yours:

  • Take the time to research: Invest in learning about the company and role by exploring their website, social media, and doing a thorough Google search. Focus on the products and services they offer, as well as awards and industry recognitions.
  • Focus on the company's values: Refer back to your research and to uncover what the company believes in. Integrate those values into your cover letter by explaining how you embody them. For example, if they value diligence, highlight how you’ve consistently met tight deadlines or successfully managed heavy workloads.
  • Align your skills with the job requirements: Read the job advert carefully and identify the most sought-after skills. Select the top three skills that you can substantiate with your most noteworthy achievements, to demonstrate your expertise in those areas.

How to format a customer success manager cover letter

Have you ever wondered about the formatting and structure of your cover letter?

Read on to discover some guidance from industry-leading professionals:

  • Within the header, include your address and contact details, the employer's name and address, and the date, followed up by a personalised salutation.
  • The body should should consist of an opening paragraph, middle paragraphs expanding on your unique experience and skills, and a closing paragraph.
  • End with a formal sign-off and your signature.
  • Choose modern fonts such as Volkhov, Chivo, or Bitter instead of the more traditional Arial or Times New Roman.
  • All of ENhancv's templates maintain single-spacing with approximately 1-inch (2.5 cm) margins on all sides to ensure a neat presentation.
  • Always send your cover letter as a PDF to keep the formatting intact and prevent any edits once submitted.

Your CV and cover letter maintain consistent formatting. Use the same fonts, margins, and style to create a professional and cohesive look for your application.

Finally, remember that Applicant Tracking Systems (the software some companies use to align job keywords to your experience, also known as ATS) do not read cover letters–it's intended solely for recruiters. Make it stand out by highlighting your achievements and relevant skills for the role.

How to write your customer success manager cover letter salutation

It's never advisable to begin your cover letter with 'Dear Sir/Madam', as it sounds comes across as impersonal.

Take the time to find out who is hiring for the role and address them directly in your cover letter greeting (e.g., 'Dear Mrs Chanceworth', 'Dear Harrod').

If you're uncertain where to find the hiring manager’s name, check the company website, look on LinkedIn, or send a courteous email requesting this information. Don't hesitate to ring reception either—they are unlikely to refuse to assist.
