Customer Success Manager Cover Letter Sample

Customer Success Manager

Dothan, AL 36303



Ms. Frederica White

Hiring Manager at FlyHigh Inc.

1366 Stockert Hollow Road

Seattle, WA 98133

Dear Frederica,

CSM is the lifeblood of modern business, that’s a fact that I’ve become well aware of in my 7 years of working in this position. When I found out about the new opening at FlyHigh Inc., it seemed like the natural next step forward, and I was very excited about being able to apply. Having increased satisfaction scores at CubedInteractive by 12%, I’m ready for new challenges: I’m sure I can help FlyHigh Inc. propel its clients even higher and faster.

At CubedInteractive, I was also able to successfully maintain a spotless 96% customer retention record, not without effort and dedication. With each and every one of my 8 long-term clients, I planned, designed, and implemented programs to boost their sales, from marketing campaigns to tools to market research.

I was glad to see that FlyHigh has a robust Business Analysis department. In my experience at Cubed, one of my primary goals was to establish constant communication and keep information flowing freely. Spearheading the implementation of this idea is my proudest achievement, as it helped generate roughly 10% more annual revenue through tighter deadlines, fewer delays, and a more streamlined approach to our customers.

Frederica, I’m positive that FlyHigh’s similar business model would allow me to flourish and keep coming up with innovative ideas to increase customer retention, as well as gain new ground. I’ve created a mock-blitz campaign to grow your client base by 5-10% within 2 years, and I’d love to meet in person to discuss it.

Supplementing it with a great resume, of course! If you’re looking for help with that, look no further than our comprehensive Customer Success Manager Resume Guide.

Customer Success Manager Cover Letter Template

2. Create a Stunning Customer Success Manager Cover Letter Header

The header of your cover letter is much like the intro statement in a service call. It needs to clearly outline who is contacting whom and other such details. 

Make sure to follow these steps to get it done right:

  • Put your contact information in the top-left corner. Include your full name, job title, email, and phone number, plus LinkedIn and/or Twitter handle (optional).
  • Leave one line blank.
  • Next, state the day you wrote the cover letter. You can also include the city name.
  • Leave another blank line.
  • Finish off by including the contact information of your addressee

3. Blow the Doors Open with an Explosive Cover Letter Opening

A good first impression goes a long way—you know it better than most. That’s why you need a professional cover letter salutation. In your greeting, again address the recruiter directly—

For example, Dear Mr Smith or Dear John will work just fine. 

If you can’t find the name of the person who’ll read your cover letter in the job ad, do some research on the company’s website or LinkedIn—or simply call the reception and ask. 

If all else fails, go with “Dear Hiring Manager”, but stay away from “Dear Sir/Madam” or “To Whom it May Concern”. We’re keeping things personal, remember? 

Then, in the opening paragraph, mention how you found out about the position and what made you want to apply—

Followed by a major professional accomplishment that’ll make the recruiter eager to read the rest of your application. Include power words and numbers in your achievement statement to really drive the message home.

4. Prove Yourself in the Middle of Your Customer Success Manager Cover Letter

Ready to put your money where your mouth is? 

Time to wow the reader with a selection of your finest workplace achievements. Just like in the introduction, make plentiful use of numbers and power verbs. Boosted customer retention by 15% sounds way better than Had better customer retention results, doesn’t it? 

So, in the second paragraph of your cover letter, show: 

  • Your understanding of what the role involves, and
  • How you excelled at similar positions in the past, with examples where possible. 

Weave in a few key skills, and you’re golden! 

One more tip before we move on: generic cover letters should be avoided like the plague, so make sure to tailor yours to the company and use their name at least once. No one likes talking to a robot for half an hour on the line to have their issue resolved, so why would recruiters bother reading robotic, copy-paste cover letters?

5. Explain Why This Company Is the Right One for You

Part of your job as a candidate is to make the recruiter’s life as easy as possible, and their decision obvious—

So don’t keep them guessing. Tell them directly why you’re the best person for the role of customer success manager at their company

Refer to the company values, structure, product, or project, and highlight what exactly draws you to the idea of working there. Perhaps you enjoy their product, or your personal values closely align with their corporate ones? Let them know! 

As well as showing your motivation, this strategy proves you’re in for the long haul—

Hiring processes are expensive, plus, proving the value of a product requires long-term commitment, so customer success management candidates with plans of staying for at least a couple of years have a better chance of getting hired.

6. Seal the Deal with a Jaw-Dropping Offer

At the end of the cover letter, summarize your excitement to join the company in a sentence or two. 

Make sure to: 

  • Reiterate the value that you know you’d bring to the table and how they would profit from it.
  • Entice them with a call to action and request a real-life conversation.

Doesn’t that look so much better than the bland Thank you for your consideration that your competition ends their cover letters with? 

Thought so!

7. Sign-Off the Customer Success Manager Cover Letter Professionally

You’re nearing the end of your cover letter journey—

It wasn’t so bad, was it? 

All that’s left are a couple of formalities: 

  • Leave a lasting mark in their memory by repeating your name and contact details one more time.
  • If you have a way of doing so, provide your digital signature.
  • Are any cover letter enclosures required? If so, don’t forget to attach them as well.
  • Save as a PDF and name your cover letter file in a professional way. Fact is, lots of people title their cover letters anonymously. By naming the file something like [Name]_CoverLetter, you stand out more, and that matters a lot.

Keep in mind that cover letters are supposed to be quick reads. The ideal cover letter length is about 3 to 4 paragraphs, and definitely under one page. 

Plus, a great cover letter that matches your resume will give you an advantage over other candidates. You can write it in our cover letter builder here. Here's what it may look like:
