Key Elements of a Strong Cover Letter
Start with a concise opening that names the role and why you are interested in the company. This helps the reader understand your intent and keeps the letter focused from the first line.
Showcase specific results such as revenue growth, deals closed, or partnerships developed with short metrics or timeframes. Concrete outcomes give your claims credibility and help hiring managers picture your impact.
Explain how your skills and experience match the company’s goals or market position in one or two short examples. Demonstrating fit shows you did research and that you can step into the role with context.
End with a polite next step that invites further conversation, such as a request for an interview or an offer to provide case studies. A specific closing line makes it easy for the reader to respond.
Cover Letter Structure
1. Header
Include your name, phone number, email, and a link to your LinkedIn or portfolio at the top of the page. Place the date and the hiring manager’s name and company below your contact details if you have them.
2. Greeting
Address the hiring manager by name when possible, for example, Dear Ms. Martinez. If you cannot find a name, use a role-based greeting like Dear Hiring Team of Company Name to keep it professional.
3. Opening Paragraph
Start with a brief hook that states the role you are applying for and one strong reason you are a fit. Keep this to two sentences to set a focused tone for the rest of the letter.
4. Body Paragraph(s)
Use one or two short paragraphs to highlight 2 to 3 achievements that match the job requirements and show measurable impact. Tie those accomplishments directly to the skills the company needs and avoid repeating your resume line by line.
5. Closing Paragraph
Summarize your interest in the role and include a polite call to action that asks for a conversation or offers additional materials. Thank the reader for their time and keep the tone confident but courteous.
6. Signature
Finish with a professional sign-off such as Sincerely followed by your full name. Add a link to your portfolio or LinkedIn beneath your name if you did not include it in the header.
Dos and Don'ts
Do tailor each letter to the company and role by referencing a specific initiative, market, or challenge the company faces. This shows attention to detail and signals that you understand their context.
Do lead with measurable results such as percentage growth, deal size, or number of partnerships you secured. Numbers help hiring managers compare candidates and understand your scale of work.
Do keep the letter to one page and use short paragraphs to improve readability. Busy recruiters will appreciate a concise, well-structured message.
Do mirror language from the job posting for key skills and responsibilities but keep your wording natural. This helps your letter pass screening and shows clear alignment with the role.
Do proofread carefully for grammar, formatting, and accurate names and titles before sending the letter. Small errors can undermine an otherwise strong application.
Don’t repeat your resume verbatim; instead, expand on one or two highlights that demonstrate fit for this role. Use the cover letter to tell a short story about impact rather than listing duties.
Don’t use vague statements like I am a hard worker without backing them up with examples or outcomes. Vague claims do not help a hiring manager assess your qualifications.
Don’t overshare unrelated personal information or long career history that does not relate to the role. Keep the focus on what matters to the employer.
Don’t include confidential client details or proprietary data you cannot share publicly. Respect confidentiality while describing the value you delivered.
Don’t use a generic opening such as To Whom It May Concern when you can find a name or a role-based alternative. A targeted greeting looks more professional and engaged.
Common Mistakes to Avoid
Relying on buzzwords without context can make your letter feel empty, so always pair a skill with a concrete example. Describe what you achieved and how it mattered to the business.
Making the letter too long is a frequent error, so keep it focused and limit details to the most relevant points. One page with two to four short paragraphs is usually ideal.
Neglecting company research leads to weak fit statements, so spend time on the company site and recent news before writing. Reference a product, market, or recent hire to show you did the work.
Using the wrong contact name or company details looks careless, so verify spelling and titles before sending. A single mistake here can reduce your chances quickly.
Practical Writing Tips & Customization Guide
Open with a brief accomplishment that directly relates to the job to grab the reader’s attention. Front-load impact so your most persuasive example appears early.
Quantify achievements when possible and include the context such as market or team size to frame the result. Context helps the reader judge how your experience scales to their needs.
Prepare a short anecdote about a partnership or deal that highlights negotiation and relationship skills for in-person interviews. This story can be adapted from your cover letter examples.
Save one line for cultural fit by mentioning a company value or mission that resonates with you and explaining why. A short cultural tie-in can strengthen your overall fit.
Cover Letter Examples
Example 1 — Career Changer (Sales to Business Development Manager)
Dear Hiring Manager,
After eight years in B2B sales, I’m ready to move into business development full time. At Meridian Solutions I grew a territory from $350K to $1.
2M in ARR by identifying three under-served verticals and launching a targeted outreach program that increased lead-to-opportunity conversion from 8% to 22% in 12 months. I built strategic partnerships with two regional resellers, which added 18% to annual revenue.
I want to bring that market-mapping and partner-development experience to AtlasTech. I’ve reviewed your partner list and see an opportunity to expand into mid-market healthcare accounts; I’d propose a pilot to win five accounts worth $450K in year one.
I’m available to discuss how I’d structure that pilot and the metrics I’d track.
Why this works:
- •Uses specific numbers (ARR, conversion rates, revenue percent) to show impact.
- •Presents a brief, realistic next-step plan tied to the company’s business.

Example 2 — Experienced Professional
Dear Talent Team,
I have seven years managing business development teams in SaaS environments, most recently leading a team of eight that grew qualified pipeline by 250% and closed $4M in new ARR last year. I prioritize data-driven prospecting: I instituted a weekly lead-scoring review that raised close rates from 14% to 21% and shortened sales cycle by 18 days.
At NovaMetrics I collaborated with product and marketing to create a vertical playbook for logistics clients, which reduced time-to-first-demo from 27 days to 12. I’m excited to bring that cross-functional approach and measurable process improvements to your team to help scale enterprise deals.
Why this works:
- •Combines leadership outcomes (team size, pipeline growth) with process wins (lead scoring, playbooks).
- •Signals readiness for higher-stakes accounts and collaboration across teams.
Practical Writing Tips
- •Start with a targeted opener. Name the role and one concrete reason you fit it; this shows focus and helps hiring managers decide fast.
- •Lead with results, not responsibilities. Replace vague duties with outcomes like "grew territory by 60%" or "closed $1.3M in new business" to prove value.
- •Match the job language sparingly. Mirror 1–2 key phrases from the posting (e.g., "channel partnerships" or "enterprise sales") to pass screening without sounding like a copy.
- •Keep paragraphs short. Use three short paragraphs: intro, achievement story, and closing ask; recruiters skim so white space helps.
- •Use active verbs and specific metrics. Say "reduced churn 7 percentage points" rather than "helped reduce churn."
- •Show one concrete plan for the role. Propose a realistic 30/60/90-day priority or pilot that ties directly to the company’s needs.
- •Quantify soft skills with context. Instead of "strong communicator," write "led 12 cross-functional workshops to align sales and product roadmaps."
- •End with a clear call to action. Ask for a 20–30 minute meeting and propose two specific time windows to speed scheduling.
- •Edit ruthlessly for clarity. Remove filler, cut passive phrases, and read aloud to catch awkward spots.
Actionable takeaway: apply these tips by revising one sentence per paragraph to include a metric, a next-step, or a tight verb.
How to Customize for Industry, Company Size, and Job Level
Strategy 1 — Tailor by industry
- •Tech: Emphasize product-led metrics and scaling. Cite ARR growth, average deal size, or trial-to-paid conversion increases (e.g., "increased trial-to-paid by 12% leading to $600K ARR"). Mention familiarity with APIs, integrations, or platform partners when relevant.
- •Finance: Stress compliance, ROI, and long sales cycles. Highlight deals with rigorous diligence (e.g., "closed three contracts after 90–120 day reviews totaling $2.1M") and metrics like payback period.
- •Healthcare: Focus on stakeholder mapping and outcomes. Note experience with clinical, IT, or purchasing teams and results tied to patient impact or cost savings (e.g., "reduced onboarding time by 30% for five hospitals").
Strategy 2 — Customize by company size
- •Startups (1–200 people): Emphasize hands-on execution, hustle, and multi-role experience. Offer examples where you built processes from scratch or secured first channel partners (e.g., "signed our first reseller, generating $120K in year one").
- •Mid-market (200–2,000): Show process and scaling wins: playbooks, CRM hygiene improvements, and onboarding programs that helped reps ramp in 6–8 weeks.
- •Large corporations (2,000+): Highlight program management, stakeholder alignment, and governance: building partner programs, managing cross-region pilots, or overseeing budgets over $500K.
Strategy 3 — Adjust by job level
- •Entry-level: Emphasize transferable wins and learning mindset. Cite internships, campus projects, or early sales metrics (e.g., "closed 18 accounts during internship worth $48K"). Offer eagerness to run a specific small pilot.
- •Mid-level: Focus on quota achievement, process ownership, and cross-functional projects. Give two clear examples of initiatives you owned and the measurable impact.
- •Senior: Highlight strategic deals, team leadership, and P&L or revenue responsibility. State the size of teams, budgets, and the percentage of company revenue tied to your deals.
Concrete customization tactics
1. Swap one paragraph to reflect the company audience: tech gets product metrics; healthcare gets stakeholder outcomes.
2. Include one sentence proposing a 30-day priority that aligns to the job level and company size (e.
g. , "Pilot three mid-market healthcare accounts to validate pricing").
3. Use company-specific numbers when possible: reference their public ARR, recent funding, or vertical focus to show research.
Actionable takeaway: pick the relevant industry block above and edit your cover letter so at least 40% of examples match the company's sector, size, and seniority level.
