A strong cover letter does one thing well: it tells a hiring manager why you, specifically, are the right fit for this role, right now.
These 20 cover letter tips cover everything from how to open with impact to the mistakes that quietly cost candidates interviews, so you can write with clarity and confidence.

1. Lead with your strongest point
Your first sentence either earns attention or loses it, so open with something that immediately shows what you bring to the table rather than a formulaic statement about the role.
This might be a relevant result, a specific skill in context, or a clear reason your background maps directly to this opportunity.
- Example: Instead of "I am writing to apply for the Marketing Manager role," try: "I have spent four years building content strategies that grew qualified leads by 40%, and the growth challenge in your job posting is exactly where I do my best work."
2. Address the hiring manager by name
Writing to a named individual rather than a generic title communicates that you researched the company and took time to write for this person specifically.
According to Resume.io's own research, 26% of hiring managers say addressing them by name makes a meaningful difference in how they perceive an application (Resume.io Cover Letter Statistics, 2025).
Check the job posting, the company website, or LinkedIn, finding a name usually takes five minutes, and it is worth every one of them.
3. Tailor every letter to the role
A cover letter that could work for any job at any company will not work well for any job at any company.
Research from Zety shows that 74% of recruiters say a tailored cover letter directly leads to an interview invitation (Zety, 2024).
Adjust the achievement you lead with, the company detail you reference, and the skills you highlight based on what this posting actually asks for.
4. Open with a hook, not a headline
"I am excited to apply for the position of..." tells the reader you are excited, but so is everyone else who applied that day.
Where Tip 1 focuses on what to lead with, this tip is about how to frame it: your opening should feel considered and specific, not assembled from a template.
A reference to a result, a precise statement of what you do, or a reason this company caught your attention all work better than a headline that says nothing.
- Example: "After three years managing a customer support team through a product overhaul that reduced complaints by 35%, I am looking for a new challenge, and your head of customer experience role is exactly that."
5. Expand on your resume rather than repeating it
Your resume states what you did; your cover letter makes the argument that what you did is precisely what this employer needs.
Choose one or two entries that connect most directly to the role and go one level deeper, explaining the context, the decision, or the outcome in a way the resume format cannot hold.
- Example: "Managing 50 client accounts meant rebuilding trust with three clients close to churning, designing a new check-in process myself, and improving portfolio retention by 18% over the following year."
6. Use the job description to inform your language
The skills listed first in a job description are the ones that matter most, and the language used reflects how the team thinks about the role.
Many companies also run cover letters through applicant tracking systems that look for exact phrases, not paraphrases, so writing "team collaboration" when the posting says "cross-functional teamwork" can filter you out before anyone reads your letter.
Identify the three to five most important requirements and work the employer's own phrasing into your letter naturally.
7. Focus on what you can do for them
One of the most common cover letter mistakes is centering the letter on your own goals rather than what you offer the employer.
Every sentence about what the role gives you is a sentence that is not making the case for your value, so reframe your instincts toward what your skills deliver for their team right now.
- Example: Replace "I am looking to grow my data analysis skills" with "My experience building dashboards in Tableau would give your team immediate visibility into the metrics currently causing delays in your reporting cycle."
8. Include one strong, specific achievement
One concrete, measurable result does more work than three paragraphs of general claims.
According to Resume.io's research, 41% of hiring managers say the introduction is the most important part of a cover letter (Resume.io Cover Letter Statistics, 2025), so bring your strongest achievement forward early and quantify it where possible.
- Example: "I redesigned the onboarding process for new hires, cutting time-to-productivity from eight weeks to five and improving 90-day retention by 22%."
9. Keep it to one page
Most hiring managers spend well under a minute on each cover letter, with 37% spending only 30 seconds (Resume.io Cover Letter Statistics, 2025).
Aim for 250 to 400 words across three to four paragraphs, and if you exceed that, cut the weakest section entirely rather than trimming everything a little.
A focused 300-word letter reads far better than a diluted 500-word one.
10. Match the company's tone and register
A formal financial services firm and an early-stage tech startup are not looking for the same voice, and sending the same register to both shows you have not paid attention to who they are.
Read the job description, the company website, and their public communications before you write, then calibrate: precise and formal for a legal or compliance role, warmer and more direct for a creative or startup environment.
Candidates who match the company's tone in writing tend to be seen as stronger cultural fits before anyone has met them, which is exactly the impression a cover letter is designed to create.
11. Choose which resume detail to expand on
Not every line of your resume deserves space in your cover letter.
Read the job description first, identify the two or three requirements that carry the most weight, and find the experience that maps most clearly to each.
If your most impressive achievement is not the most relevant one for this role, save it for the interview and lead with what fits.
12. Research the company before you write
Referencing something specific about the company, such as a recent initiative, a stated value, or a challenge they have discussed publicly, shows that you wrote this letter for them rather than for any employer in your sector.
Keep the reference brief and tied to your own background, because one well-placed observation is enough to make the letter feel personal rather than produced.
- Example: "I read about your Q1 expansion into the Southeast market and the operational scaling challenges that came with it. Bringing regional teams up to speed quickly is something I have done twice, and it is where I feel most effective."
13. Proofread carefully and more than once
Research by Resume Genius found that 35% of applicants include spelling or grammatical errors in their cover letters, a factor frequently cited in rejection decisions (Resume Genius, 2025).
Read your letter aloud to catch phrasing that looks correct on screen but sounds wrong when spoken, check the company name specifically, and ask someone else to review it before you send.
Spellcheck will not catch the wrong word used correctly or a leftover employer name from a previous application version.
14. Avoid generic openers and dated salutations
"To Whom It May Concern" and "Dear Sir or Madam" are read as immediate indicators that the same letter was sent to every company without looking at who was on the other end.
The same applies to opening lines like "I am writing to apply for..." or "Please find attached my application," which delay the point and waste the most valuable space in your letter.
Your opener should communicate something about you or your fit, not simply acknowledge that you are submitting an application, which the application itself already does.
15. Use keywords from the job posting
Many companies run cover letters through applicant tracking systems before a human reads them, and these systems look for specific phrases rather than synonyms.
Identify the skills and requirements that appear most prominently in the posting and work those exact phrases into your letter naturally, placed within sentences that reflect your genuine experience rather than bolted on as a list.
This both improves your chances of clearing automated filters and shows the hiring manager that you understood what the role actually requires.
16. Do not apologize for gaps or missing experience
Phrases like "despite my limited experience in X" or "while I have not yet worked in Y" shift focus onto your weaknesses before the reader has had the chance to weigh your strengths.
Focus on your transferable skills, your record of learning quickly, and the experience you do have that is relevant.
If there is a genuine employment gap in your timeline, one brief and confident sentence is appropriate, framed around what you did or learned during that period, not around reassuring the employer.
17. Write a confident, specific close
"I look forward to hearing from you" is polite but inert, placing the entire decision with the employer and contributing nothing to the letter.
A well-written close reaffirms your interest, confirms your availability, and makes the next step clear without sounding pushy.
Expressing genuine enthusiasm and inviting a conversation is enough.
- Example: "I would welcome the chance to discuss how my background in operations could support your team's targets this year. I am available for a conversation at your convenience and can be reached at [contact details]."
18. Keep your sentences short and active
Use active constructions throughout, "I led the project" rather than "the project was led by me", and aim for sentences of around 15 to 20 words where possible.
Reading your draft aloud is the most reliable editing technique for a document this short: if you run out of breath before a sentence ends, split it.
The best cover letters feel effortless to read, which is the result of careful editing rather than natural talent.
19. Do not submit AI-generated text without rewriting it
49% of hiring managers say they automatically dismiss applications they believe have been AI-generated (Resume.io, 2024), and the patterns are recognizable: vague enthusiasm, nothing specific, an introduction that calls the company "innovative" without explaining why.
AI tools can help you overcome a blank page or structure your thoughts, but the final letter must sound like you, your voice, your specific examples, your actual reasons for wanting the role.
Pay attention to the font and formatting too, since AI-drafted documents sometimes arrive with inconsistent styling that undermines an otherwise strong letter.
20. Send a cover letter even when it is listed as optional
When a posting marks a cover letter as optional, most applicants skip it, which is a missed opportunity.
A well-written letter communicates effort and genuine interest, and 83% of hiring managers say a strong cover letter can help a candidate overcome a weak or generic resume (Resume.io Cover Letter Statistics, 2025).
Browse examples or templates to get started, and write it properly, a brief, tailored letter is far more effective than skipping the step entirely.
Key takeaways
- Address your letter to a named hiring manager where possible. Personalization is one of the simplest ways to stand out from the majority of applicants who do not bother.
- Tailor each letter to the specific role by reflecting the language of the job description and including one specific reference to the company or team.
- Lead with your strongest, most relevant achievement and focus entirely on what you can deliver for the employer, not what the role offers you.
- Keep the letter to one page and 250 to 400 words. Brevity communicates confidence, and most hiring managers spend less than a minute reading.
- Proofread carefully and rewrite any AI-generated text in your own voice. Errors and generic phrasing are among the most common reasons strong candidates are dismissed before interview.
Frequently asked questions
Here are a few questions that often come up about cover letter writing.
Should you always include a cover letter?
In most cases, yes. Even when a posting marks it as optional, a well-written cover letter communicates effort and genuine interest that most applicants will not show.
The only exception is a posting that explicitly instructs you not to include one.
