What Does a Good Cover Letter Look Like? (Annotated Example)

A good cover letter is short, specific, and obviously written for one job. It opens with why you're a fit, proves it with one or two concrete results, and closes with a clear next step, all in about 300 words on a single page. Below is a full annotated example so you can see exactly what that looks like, then copy the structure for your own.

The annotated example

Here's a complete cover letter for a mid-level marketing role. Read it once straight through, then we'll break down why each part works.

Dear Maya Chen,

I've been following Brightline's move into B2B email tooling, and the Senior Lifecycle Marketer role is exactly the kind of work I want to do next. At Verda, I owned the onboarding email program end to end, and I think that experience maps closely to what your team is building.

In my last role I rebuilt a stale welcome sequence that hadn't been touched in two years. By rewriting it around the user's first "aha" moment and adding behavior-based branching, I lifted trial-to-paid conversion from 4.1% to 6.8% over two quarters. I also set up the testing process the team still uses, so the gains kept compounding after I'd moved on to other projects.

What draws me to Brightline specifically is that you're solving lifecycle marketing for companies that can't afford a ten-person growth team. That's a real constraint I've worked inside, and I'd bring a bias toward simple systems that a small team can actually run.

I'd love to talk through how I'd approach your first 90 days. Thank you for considering my application.

Best, Sam Rivera

Why each part works

That letter does a lot in four short paragraphs. Here's the breakdown.

The greeting uses a real name. Sam found the hiring manager on LinkedIn. A name signals you did five minutes of homework, and it beats the generic openers most applicants default to.

The opening paragraph names the company, the role, and a reason for interest that isn't generic. "I've been following Brightline's move into B2B email tooling" proves Sam actually knows what the company does. It then bridges to relevant experience without burying the lede.

The middle paragraph is the proof. It's one story with a number: 4.1% to 6.8% conversion. It doesn't just claim "results-driven"; it shows the result and hints at how (rewriting around the aha moment, behavior-based branching). The last sentence shows lasting impact.

The third paragraph answers "why us." It connects Sam's experience to a specific thing about the company, which makes the letter impossible to paste into another application unchanged.

The close proposes a next step ("how I'd approach your first 90 days") and stays warm without groveling.

The structure you can copy

Strip the example down and you get a reusable skeleton. Fill in your own details and you have a tailored letter in fifteen minutes.

If you want this broken into a fill-in-the-blank version, the cover letter template and format guide lays it out, and the step-by-step writing guide walks through drafting each section from scratch.

Good vs. weak: side by side

The difference between a strong letter and a forgettable one usually comes down to specificity. Same applicant, two openings:

The weak column could belong to anyone applying anywhere. The good column could only have been written by this person for this job. That's the whole game.

Common things that quietly sink a good letter

Even a well-structured letter gets weaker when it does any of these:

• Restating your resume. The letter is context and proof, not a second list of bullet points. Pick one story, not five.
• Talking only about what you want. Lead with what you bring; the company cares about its problem, not your career goals.
• Going long. If it spills past one page or 350 words, cut. More words rarely add more signal. See how long a cover letter should be for the specifics.
• Vague enthusiasm. "I'm passionate about your mission" means nothing unless you say what about the mission and why it connects to you.
• Zero customization. A letter that never names the company reads like spam, because it basically is.

Tailoring it for every job without burning an hour

The structure stays the same; the details change. For each application, swap the company name, the "why them" paragraph, and ideally the proof story so it matches what the role actually needs. If you're applying to a dozen roles, that's the part that eats your evening.

This is where JobRizzer helps: it autofills the application form across systems like Workday, Greenhouse, Lever, and Ashby, and on Pro it tailors your resume to each posting so the wording lines up with the role. You still write the human parts and review everything before you submit, but the repetitive copying disappears. If you're still deciding whether a letter is worth it at all, the do-you-need-a-cover-letter guide is the honest version.

A good cover letter isn't impressive prose. It's a short, specific argument that you understand the job and have done something like it before. Use the example above as your template, keep it to one page, and change the details every time.
