25+ Most Important Cover Letter Checklist Before You Submit

You've done it. You've poured your skill, your experience, and your aspirations into a one-page document. Your CV is polished. Your cover letter is (you hope) compelling. You're at the final, nerve-wracking moment: staring at the “Send” button on your email.

A wave of panic washes over you.

• “Wait… did I spell the manager's name ‘Adebayo' or ‘Adeboye'?”
• “Oh, God, please tell me I didn't leave ‘Dear KPMG' in my application to PwC…”
• “Does this sound too desperate? Does it sound ‘beggy'?”
• “What if my phone number has a typo and they can't even call me?”

This is the “pre-submission anxiety” every Nigerian job seeker knows. In a market this competitive, you don't get second chances. A recruiter in Lagos, sifting through 500+ applications, isn't just looking for reasons to hire you; they are looking for easy reasons to reject you and shrink the pile.

A typo, a wrong name, a lazy “copy-paste” error—these are the “unforced errors” that get your application “binned” in six seconds, before your CV is ever opened.

This 4000+ word guide is your final, non-negotiable inspection. This is your Ultimate Cover Letter Checklist. Do not, under any circumstances, hit “send” until you have gone through every single item on this list.

The “Fatal Flaw” Triage (The 5-Minute Emergency Scan)

These are the deal-breakers. These mistakes are not just “bad”; they are fatal. They signal a complete lack of seriousness and attention to detail.

1.1. Check the Company Name

• The Check: Read your letter. Find the company name. Is it the correct company you are applying to?
• The Mistake: You wrote a great letter for KPMG and then “recycled” it for PwC… but you forgot to change the name “KPMG” in the body.
• The Fix: Use Ctrl + F (Find) right now. Type in the name of the last company you applied to. If it shows up, you just saved your application. Type in the name of the current company. Is it spelled 100% correctly? (e.g., Is it “PriceWaterhouseCoopers” or “PwC”? Is it “Interswitch” or “InterSwitch”?) Check their website.

1.2. Check the Job Title

• The Check: Does the job title in your letter exactly match the job title in the advert?
• The Mistake: The advert says “Graduate Trainee – Finance.” Your letter says “Application for Graduate Accountant.” This shows you're just “spraying” applications and didn't even read the title.
• The Fix: Copy and paste the exact job title (and Job ID, if they have one) from the advert into your subject line and opening paragraph.

1.3. Check the Recipient's Name (If You Have One)

• The Check: If you did your research and found the hiring manager's name (e.g., “Mrs. Bisi Adebayo”), did you spell it perfectly?
• The Mistake: You spell it “Mrs. Bisi Adeboye.” This is worse than “Dear Sir/Ma.” You tried to be detailed, but your sloppiness insulted them.
• The Fix: Triple-check the spelling against the LinkedIn profile or source where you found it.

1.4. Check Your Own Contact Info

• The Check: Is your phone number correct? Is your email correct?
• The Mistake: Your phone number has a typo. 0801-234-5678 instead of 0801-234-5687. The recruiter loves your application, tries to call you… and it's a “number does not exist.” You just lost the job and will never know.
• The Fix: Look at your header. Call your own number. Type your own email into a new “To” field. Does it look right? Is your LinkedIn link a clickable hyperlink that actually works?

The “Naija-Proofing” Checklist (Tone & Professionalism)

This section is critical for the Nigerian market. We are often taught a style of “humble” writing that comes across as “desperate” and “unprofessional” in a modern business context.

2.1. Check for “Beggy” Language

• The Check: Use Ctrl + F to find these words.
• The Mistake: “I am humbly pleading with you…” “I beg you to consider…” “I am a poor graduate…” “This is my only hope…”
• Why it's a Mistake: This is not a “plea for help.” It's a business proposal. You are an asset, not a liability. This language screams “no confidence” and “desperation.”
• The Fix: Delete every single one.
  • Before: “I humbly plead for you to give me a chance.”
  • After: “I am confident that my skills in [X] will add significant value to your team.”
  • Before: “I am a poor graduate just trying to survive.”
  • After: “As a recent graduate, I am eager to apply my academic knowledge and hands-on skills…”

2.2. Check the Salutation

• The Check: How does your letter start?
• The Mistake: Dear Sir/Ma,
• Why it's a Mistake: It's not fatal, but it's 2025. It's weak, “colonial,” and lazy. It shows you didn't spend even 5 minutes on LinkedIn trying to find who you're writing to.
• The Fix:
  • Good: Dear Hiring Manager,
  • Better: Dear [Job Title] Hiring Team, (e.g., “Dear Marketing Team,”)
  • Best: Dear [Mr./Mrs./Dr. Name], (e.g., “Dear Mrs. Adebayo,”)

2.3. Check the Closing Sign-Off

• The Check: How does your letter end?
• The Mistake: Awaiting your favourable response, or Hoping for a positive reply,
• Why it's a Mistake: It's passive. You are a passenger hoping for good luck.
• The Fix: Use a confident, professional, and active Call to Action (CTA).
  • Before: “Awaiting your favourable response.”
  • After: “I am available for an interview at your earliest convenience and look forward to discussing my qualifications.”
  • Before: “Hoping to hear from you soon.”
  • After: “I am eager to learn more about this opportunity and discuss how I can be an asset to [Company Name].”

2.4. Check Your “Sincerely” / “Faithfully”

• The Check: What sign-off did you use?
• The Mistake: You used Dear Mrs. Adebayo, (a specific name) and ended with Yours faithfully,. This is grammatically wrong.
• The Fix (The Rule):
  • If you know the name (Dear Mrs. Adebayo,): End with Yours sincerely,
  • If you don't know the name (Dear Hiring Manager,): End with Yours faithfully,
  • The 2025 “Safe” Fix: Just use Best regards, or Sincerely,. They work for everything and are modern and professional.

2.5. Check for “Naija-isms” and Slang

• The Check: Did any informal language slip in?
• The Mistake: “I'm looking for a job to help my hustle.” “This role is a big deal.” “I won't fall your hand.”
• The Fix: Delete. This is a formal business letter. Use professional synonyms (“my career development,” “a significant opportunity,” “I will not disappoint”).

The Content & Persuasion Checklist (The “Sales Pitch”)

Does your letter actually work? Does it sell you?

3.1. The “Tailoring” Test (Is this a “Copy-Paste” Letter?)

• The Check: Read your letter. Now, could you send this exact same letter to a different company, just by changing the name?
• The Mistake: If the answer is “Yes,” you've written a generic letter. It will fail.
• The Fix: Go back to the Job Description (JD). Find 2-3 specific keywords (e.g., “financial modeling,” “stakeholder management,” “B2B sales pipeline”). Now, weave those exact phrases into your body paragraphs.

3.2. The “Why Them?” Test

• The Check: Does your letter say anything about why you want to work for this specific company?
• The Mistake: Your letter is all “Me, Me, Me.” (“I want this job. I have these skills. I am great.”)
• The Fix: Add one sentence showing you did 5 minutes of research.
  • Example: “I am particularly drawn to [Company Name]'s recent work in [Project X]…”
  • Example: “Your company's reputation for [Company Value, e.g., ‘innovation in the fintech space'] is what inspired me to apply.”

3.3. The “CV Echo” Test

• The Check: Is your cover letter just a paragraph version of your CV's bullet points?
• The Mistake:
  • CV: “• Grew sales by 20%.”
  • Letter: “In my last role, I grew sales by 20%.”
• Why it's a Mistake: This is a waste of the recruiter's time. They just read that. The letter's job is to expand, not repeat.
• The Fix: Use the P.A.R. (Problem-Action-Result) method to tell the story behind that bullet point.
  • After: “My CV highlights a 20% sales growth. This was the (R)esult of a (P)roblem I identified: our old leads were cold. My (A)ction was to design and launch a new email re-engagement campaign that… “

3.4. The “Value Proposition” Test

• The Check: Is your opening paragraph boring?
• The Mistake: “I am writing to apply for the role of [X] which I saw on [Y]. I am a graduate of [Z].” (This is a “dead” opening. It has no hook.)
• The Fix: Re-write your opener to be a “value proposition.”
  • Before: “I am writing to apply for the Junior Accountant role…”
  • After: “As a recent First Class accounting graduate with a 6-month SIWES placement where I helped reconcile over N50M in accounts, I am writing to apply for your Junior Accountant role…” (This is a hook).

3.5. The “NYSC / SIWES / Side-Hustle” Test

• The Check (for Graduates): Did you sell your “non-traditional” experience, or did you just list it?
• The Mistake: “I am a fresh graduate with no experience, but I did my NYSC at a school.”
• The Fix: Spin that experience.
  • After: “My experience is not just academic. During my NYSC placement, I was entrusted to [Task, e.g., ‘manage a class of 50 students'], which honed my skills in [Business Skill, e.g., ‘public speaking, stakeholder management, and conflict resolution'].”
  • (Your IG business = E-commerce, Marketing, Customer Service)
  • (Your SIWES = Real-world problem-solving)

The Formatting & Visual Checklist (The “6-Second Scan”)

Before they read a word, they see the document. A messy, crowded page gets an instant “No.”

4.1. The “Wall of Text” Test

• The Check: Open your letter. Do you see giant, dense blocks of text? Are any paragraphs longer than 6 lines?
• The Mistake: A “wall of text” is intimidating and unreadable on a mobile phone.
• The Fix: Break it up. Shorter paragraphs. Use white space as a breathing tool. An ideal letter has 4-5 short, punchy paragraphs.

4.2. The “One-Page” Test

• The Check: Is your cover letter one page?
• The Mistake: It's 1.5 pages.
• Why it's a Mistake: It's not a Ph.D. thesis. It's a sales pitch. Going over one page signals you are rambling, can't summarize, and don't respect the recruiter's time.
• The Fix: Be ruthless. Cut sentences. Remove “fluff” words (“really,” “very,” “I believe that…”). Get it onto one single page. (The only exception is for very senior, C-level, or academic/research roles).

4.3. The “Font” Test

• The Check: What font did you use? Is it consistent?
• The Mistake: You used Comic Sans or Times New Roman (which looks dated). Or you used 5 different fonts and sizes.
• The Fix: Use one professional, modern “sans-serif” font (e.g., Calibri, Arial, Roboto, Garamond). Use one size (11pt or 12pt) for the body.

4.4. The “Alignment” Test

• The Check: How is your text aligned?
• The Mistake: You used “Justified” text (where both left and right edges are aligned).
• Why it's a Mistake: “Justified” text looks neat, but it creates weird, ugly gaps between words and is harder to read.
• The Fix: Use Left-Alignment only. It's the standard for business.

4.5. The “Synergy” Test

• The Check: Put your CV and your cover letter side-by-side.
• The Mistake: They look like they came from two different people.
• The Fix: Make the headers match. The [Name, Phone, Email, LinkedIn] block at the top of your CV should use the same font, size, and layout as the header on your cover letter. This is a “pro-level” move that makes your application look like a single, branded package.

The “Technical & Submission” Checklist (The Final Click)

You're almost ready to send. This is the final-final check.

5.1. The “File Format” Test

• The Check: What file format are you attaching?
• The Mistake: You're attaching a .docx (Microsoft Word) file.
• Why it's a Mistake:
  1. It's unprofessional.
  2. Your formatting will break when the recruiter opens it on their phone or a different computer.
  3. It's editable. You're sending an “unfinished” document.
  4. It can carry viruses, so many servers block it.
• The Fix: ALWAYS save and send as a PDF. (File > Save As > PDF).

5.2. The “File Name” Test

• The Check: Look at the name of your file.
• The Mistake: CV_final_final_new.pdf or Doc1.pdf.
• Why it's a Mistake: It's disorganized and childish. The recruiter is downloading 200 files. How will they find yours?
• The Fix: Use a clean, professional naming convention.
  • Tunde_Adebayo_Cover_Letter_KPMG.pdf
  • Tunde_Adebayo_CV.pdf

5.3. The “Submission Method” Test

• The Check: Re-read the “How to Apply” section of the job advert one last time.
• The Mistake: The advert says, “Apply via our online portal ONLY.” You are emailing them.
• Why it's a Mistake: You've just failed the first test: “Can this person follow simple instructions?” Your application will be deleted, and you'll be blacklisted as spam.
• The Fix: If it says “portal,” use the portal. If it says “email,” use email. Do exactly what they say.

5.4. The “Email Body” Test

• The Check: If you are submitting via email, what's in the email body?
• The Mistake: It's empty. Just a subject and two attachments.
• Why it's a Mistake: This is lazy and a massive wasted opportunity.
• The Fix: Use the “Hybrid Method.” Your email body should be a short, 3-paragraph “mini-cover letter” that acts as a “hook.” It should not be your full letter.
  • Para 1: “Dear [Name], I'm applying for [Role]…”
  • Para 2: “My [X] years of experience and [Key Achievement]… make me a strong fit.”
  • Para 3: “My full CV and formal cover letter are attached. I look forward to hearing from you.”

5.5. The “Email Subject Line” Test

• The Check: What is your email subject line?
• The Mistake: (No Subject) or Application or CV
• The Fix: Be clear, professional, and follow their instructions.
  • Good: Application for Junior Accountant - Tunde Adebayo
  • Best (if they gave one): Application for Junior Accountant (Job ID: #45-B)

The Ultimate “Gbagaun” Catcher: The Read-Aloud Test

You have done everything. You are 99% sure it's perfect. Now, for the final 1%.

Do this right now: Read your entire cover letter out loud to yourself.

• Why? When you read in your head, your brain sees what it expects to see. It skips over typos.
  • You will read “I am writing to apply for the role” even if you wrote “I am writing to apply for role.”
• When you read out loud, your ears catch what your eyes missed.
• You will hear the “gbagaun” (the stumble). You will hear the missing “a” or “the.” You will hear the sentence that is too long and runs out of breath. You will hear the typo that spell-check missed (e.g., “I managed the manger…” instead of “I managed the manager…”).

This one trick will catch 99% of all remaining errors.

Hit “Send” with Confidence

Your job application is not just a document; it's a professional proposal. It's a reflection of your brand, your seriousness, and your attention to detail.

These checks might seem “small” or “tedious.” But in a market where 500 people are fighting for one job, the person who gets these “small” things right is the one who signals excellence.

You've done the hard work. You've gone through the checklist. You've caught the “fatal flaws,” fixed the “Naija-isms,” and polished your “sales pitch.”

Now… you can hit “send” with total confidence.
