Key Elements of a Strong Cover Letter
Start with your full name, phone number, email, and LinkedIn or portfolio link if you have one. Include the employer name and job title so the reader sees the match at a glance.
Lead with a brief sentence that names the role and why you are interested in it. Use a concrete example or result to make the reader want to keep reading.
Highlight 2 to 3 qualifications that match the job, such as calendar management, data entry, or vendor coordination. Use short achievement statements with numbers when possible to show impact.
End by restating your interest and inviting next steps, such as a call or interview. Keep the tone confident and polite while offering your availability for follow up.
Cover Letter Structure
1. Header
Include your contact information at the top and the employer details below it. Add the job title and reference number if the posting lists one so your application is easy to track.
2. Greeting
Address the hiring manager by name when you can by checking the job listing or company website. If you cannot find a name, use a professional greeting that references the team or department you are applying to.
3. Opening Paragraph
Start with the role you are applying for and a short statement about why you are a good fit. Mention one specific accomplishment or strength that ties directly to the job description.
4. Body Paragraph(s)
Use one or two short paragraphs to expand on your most relevant skills and examples. Focus on tasks that matter to the role such as scheduling, customer service, document management, or process improvements.
5. Closing Paragraph
Reiterate your enthusiasm for the role and invite the hiring manager to contact you for next steps. Offer a brief note about your availability for an interview or to provide references.
6. Signature
End with a professional closing such as Sincerely or Best regards followed by your full name. Add a phone number and email below your name so the reader can reach you easily.
Dos and Don'ts
Customize each letter to the job by echoing key terms from the posting and focusing on the most relevant tasks. This helps the hiring manager see how your experience maps to their needs.
Lead with a strong opening that names the position and a specific achievement or strength. A clear first sentence increases the chance the reader continues.
Use numbers and brief examples to show impact, such as reducing scheduling errors or processing invoices each week. Quantified results make your claims more credible.
Keep the letter to one page and use short paragraphs to make it scannable. Hiring managers often skim so clarity matters.
Proofread carefully for typos and formatting consistency, and ask a friend to read it if you can. Small errors can distract from otherwise strong qualifications.
Don’t repeat your entire resume line for line in the cover letter. Use the letter to add context and highlight the most relevant accomplishments.
Don’t use vague phrases like I am a hard worker without showing what you did. Concrete examples are more persuasive than empty labels.
Don’t include salary expectations unless the job asks for them, as that can prematurely limit negotiations. Wait until the employer prompts for compensation.
Don’t lie about your experience or inflate metrics, since inaccuracies can be uncovered during reference checks. Honesty builds long term trust.
Don’t submit a generic template without customizing the company name, role, and a detail that shows you researched the employer. Small personal touches make a big difference.
Common Mistakes to Avoid
Using a one-size-fits-all letter that does not reflect the job posting, which makes you blend in with other applicants. Tailor your examples to the specific responsibilities listed.
Having a weak opening that fails to state the role or your main qualification, which loses the reader’s interest. Start with a clear hook tied to the job.
Listing duties without results or context, which leaves the employer guessing how you performed. Add a short outcome or metric to clarify impact.
Writing dense paragraphs that are hard to scan, which can frustrate hiring managers who review many applications. Break content into short paragraphs for readability.
Practical Writing Tips & Customization Guide
Mirror language from the job posting for skills and tools while keeping your voice natural. This helps your letter pass initial keyword scans and resonate with the reader.
Start the body with your most relevant accomplishment rather than a full career summary. Putting the strongest point first captures attention quickly.
Mention software, tools, or systems you use that are listed in the posting, such as Microsoft Office or scheduling platforms. Specific tools show you can step into the role sooner.
Close by offering availability for a call and mentioning you can provide references or a work sample. That gives a clear next step and shows readiness to move forward.
Cover Letter Examples
### Example 1 — Career Changer: Retail Manager to Administrative Assistant
Dear Ms.
After seven years managing a busy retail store, I’m excited to apply for the Administrative Assistant role at Greenfield Consulting. I scheduled and supervised 20+ staff per week, managed weekly payroll for a $50,000 monthly budget, and introduced a restocking process that cut inventory time by 30%.
Those responsibilities taught me calendar management, vendor communication, and error-free record keeping—skills I now apply with Microsoft Office and Google Calendar. In my last role I coordinated vendor deliveries across three locations and handled travel bookings for regional managers, both tasks that align with your job description.
I’m ready to transfer that operational focus to support your consulting team’s schedules and client logistics.
Sincerely, Alex Torres
What makes this effective: Specific numbers (20+ staff, $50,000, 30%) show measurable impact and clear skill transfer from retail operations to administrative duties. It ties past duties to the job’s core tasks.

### Example 2 — Recent Graduate: Communications Major
Dear Hiring Committee,
I recently graduated with a B. A.
in Communications (3. 7 GPA) and completed a five-month administrative internship at Harbor Health, where I processed 200+ patient intake forms and reduced a filing backlog by 40% through a refile system I designed.
I’m proficient in Google Workspace, Microsoft Excel (vlookups, pivot tables), and calendaring tools. During my internship I scheduled 30+ appointments weekly for a team of seven clinicians and tracked insurance authorizations with 98% accuracy.
I want to bring that attention to detail to the Administrative Assistant role at Riverstone Medical Group, where strong patient communication and fast, accurate processing matter.
Thank you for considering my application—I'm available for an interview next week and can start two weeks after an offer.
Best, Maya Singh
What makes this effective: Concrete metrics (200+ forms, 40% backlog reduction, 98% accuracy) demonstrate competence and readiness, while tools and availability show practical fit.
Cover Letter Examples (continued)
### Example 3 — Experienced Professional: Executive Assistant
Dear Mr.
For the past seven years I’ve supported two VPs and a CFO as Executive Assistant at Parklane Holdings. I manage complex calendars for three executives, coordinate 50+ meetings monthly across four time zones, and oversee travel arrangements that save an average of 14 hours per month in executive time.
I supervise a team of three administrative staff and implemented a billing reconciliation process that reduced invoice errors by 15%. I use Outlook, Concur, and Asana daily and I proactively prepare briefing packets and follow-up notes to keep senior leaders informed.
I’m drawn to your firm’s focus on growth and would welcome the chance to improve executive time use and meeting outcomes at Brightwood Partners.
Regards, Samuel Lee
What makes this effective: Shows leadership (managing staff), scope (50+ meetings, four time zones), and measurable process improvements (14 hours saved, 15% fewer invoice errors), which fit senior-support roles.
Practical Writing Tips
1. Open with a specific connection.
Name the role, the company, and one reason you fit in the first 1–2 sentences to grab attention and show you tailored the letter.
2. Lead with impact: use numbers.
Quantify responsibilities (e. g.
, 50 meetings/month, managed $50K budget) to show scale and competence.
3. Match the job posting language.
Mirror 2–3 exact phrases from the posting (e. g.
, “calendar management,” “client billing”) so ATS and hiring managers see clear relevance.
4. Use three short paragraphs.
Intro, two achievement-driven body paragraphs, and a one-sentence close keeps the letter concise and scannable.
5. Choose concrete verbs.
Use words like managed, scheduled, processed, coordinated—verbs that describe actions and outcomes rather than vague claims.
6. Show a relevant tool or process.
Mention specific software (Outlook, Concur, Asana) or a process you improved and include the result to prove practical skill.
7. Keep tone professional but human.
One sentence that shows personality—why the company appeals to you—builds fit without sounding informal.
8. End with a clear next step.
State your availability for interview or start date to make it easy for the recruiter to act.
9. Proofread with a checklist.
Check name spelling, dates, and file name (e. g.
, “Alex_Torres_Cover. pdf”) to avoid simple, costly errors.
Customization Guide: Industry, Company Size & Role Level
Start by scanning the job posting for three priorities: required tools, top responsibilities, and language about culture or metrics.
1) Emphasize the right skills per industry
- •Tech: Highlight ticketing systems, ticket resolution times, and comfort with SaaS. Example: “Managed support queue of 120 tickets/month and reduced response time from 48 to 24 hours.”
- •Finance: Stress accuracy, confidentiality, and compliance. Example: “Reconciled monthly invoices with 99% accuracy for a $200K budget.”
- •Healthcare: Show HIPAA awareness, patient scheduling, and intake volume. Example: “Scheduled 100+ patient visits weekly and maintained compliant records.”
2) Tailor tone and scale to company size
- •Startups: Use a flexible, can-do tone and highlight multitasking or process creation (e.g., set up first expense system for a 12-person team).
- •Corporations: Use formal, process-oriented language and emphasize experience with standardized systems and large teams (e.g., coordinated meetings for a 200-person division).
3) Adjust emphasis by job level
- •Entry-level: Lead with learning, reliability, and specific software basics. Cite internship numbers or class projects (e.g., processed 150 invoices during internship).
- •Senior roles: Lead with leadership, process improvements, and metrics (e.g., supervised three assistants and cut meeting prep time by 20%).
4) Swap three parts to customize quickly
- •Opening: Replace a generic sentence with one that cites the company’s name and mission.
- •Middle: Swap in 1–2 industry-specific achievements with numbers.
- •Closing: Mention a concrete next step tied to the company (e.g., “I can start within two weeks to support your Q2 planning”).
Actionable takeaway: Before submitting, edit three elements—opening sentence, one achievement, and closing line—to match industry, company size, and role level. This three-change method yields a customized letter in under 15 minutes.
