“Should I even bother including a cover letter these days?”
If you are asking this question, it means you understand that simply submitting an updated resume is rarely enough to pass the initial screening—it implies a lack of effort or, worse, indifference toward the role itself. The short answer is yes, you should absolutely include one, but your focus must shift from merely *including* one to using it as an opportunity for curation. It is not a narrative retelling of your resume; it is a highly targeted argument explaining why the company needs your specific combination of skills right now.What is the real purpose of a cover letter?
The primary function of a cover letter today is to bridge the gap between the sterile bullet points on your resume and the living, breathing reality of what you can contribute to an employer’s bottom line. Your resume proves that you have done things; the cover letter must prove that you understand why those things matter in the context of this particular job and industry. It is less about summarizing your career history and more about demonstrating fit—a complex mix of cultural alignment, technical capability, and genuine enthusiasm for their mission.
Many applicants treat the cover letter as a narrative journal, listing accomplishments they feel are important. This wastes valuable space. Instead, view it as a piece of direct marketing copy written solely to persuade a busy hiring manager or recruiter. You must address three things quickly: (1) Why *this* company specifically? (2) Why *this* role, and not just any similar role? (3) What is the single biggest problem you are uniquely positioned to solve for them?
A successful letter shows that you have done homework. If the job description emphasizes rapid growth in X area, your cover letter should use language that mirrors that concern and offer an anecdote about a time you successfully navigated similar rapid growth. You are essentially providing intellectual proof of concept before they even invite you for an interview.
How long should my application letter be?
You must keep it under one page—ideally, three to four focused paragraphs that take no more than five minutes to read. If your letter exceeds a single sheet of standard US letter paper, the reader will assume you are either rambling or lack the discipline required for concise professional communication.
Think about what holds attention in a modern office setting. It is scarce. You need to respect that scarcity with brevity while maintaining depth. This means ruthless editing. If a sentence does not advance your argument toward why you are perfect for this job, cut it immediately. A common mistake is dedicating too much space to thanking the reader or providing excessively detailed background on previous jobs that are irrelevant to the opening opportunity. Do not summarize every past role; pick one or two specific experiences that directly map onto the needs outlined in the job posting.
The proper length ensures that even if a hiring manager only skims your letter, they absorb the core message: I understand your problem, and I am the solution. If you take up too much space with generalized praise or tangential professional achievements, the reader will lose focus on the central thesis of your candidacy.
Is a cover letter necessary for applying to jobs?
While some automated Applicant Tracking Systems (ATS) may treat the submission of a cover letter as optional—allowing you to upload just a resume and a simple form—you should always write one as if it is mandatory. To skip writing it is to concede an immediate advantage to your competition.
The necessity of the letter lies in its ability to convey tone, personality, and sophisticated communication skills. These are elements that ATS cannot read and which hiring managers use to filter out candidates who lack critical thinking or persuasive writing abilities. Furthermore, when you write a cover letter specifically addressing the company's mission (e.g., discussing their commitment to sustainability if they are an environmental firm), you demonstrate cultural fluency—a highly valued trait.
The trade-off here is time versus impact. Spending two hours crafting a perfect, tailored letter for a job might seem like a huge investment when compared to the five minutes it takes to upload a resume. However, that initial effort dramatically increases your odds of getting past the first human gatekeeper because you are not just *applying*; you are making a specific case for employment.
How should I address my letter if I don’t know the hiring manager's name?
Never use generic salutations like "To Whom It May Concern" or "Dear Hiring Manager." This signals to the reader that you did not bother doing basic research, and it immediately undermines your perceived professionalism. Your goal is to find a specific person—the department head, the hiring manager, or even an HR contact who specializes in the role you are applying for.
If, after thorough investigation (checking LinkedIn, the company website 'About Us' page, or even calling the main number and politely asking, "Who handles recruiting for the [specific department]?"), you absolutely cannot find a name, you must pivot your salutation to be departmental. Instead of addressing an individual, address the role itself or the team structure. Examples include: "Dear Marketing Team Hiring Committee," or "Dear Director of Product Development." This shows that you know *who* needs to read this letter and who it relates to within the company structure.
If all else fails—and this is rare, requiring a true dead end in research—you can use the name of the role: "Dear [Job Title] Hiring Team." The key principle here remains that you must sound like you were talking directly to a specific group of people, not sending a mass email blast.
How do I properly close and follow up after submitting my application?
Closing your letter is perhaps the most critical part, as it dictates the professional tone with which you exit the conversation. Never end weakly by saying, "I look forward to hearing from you." This places all the burden of action on the reader, who may be overwhelmed with hundreds of other applications.
A strong closing requires an explicit call-to-action. You must reiterate your enthusiasm and guide them toward the next step. Instead of waiting, suggest a follow-up discussion centered around solving a problem you identified for them in the letter's body. For example: "I am eager to discuss how my experience with X system could immediately improve your team’s efficiency by an estimated Y percentage."
After submitting the application, do not wait silently. Wait approximately one week and then send a brief follow-up email. This is not nagging; it is professional persistence. In this follow-up, reference something specific from your original letter or interview preparation—a recent company announcement, a new product line, or a challenge mentioned in an industry article. This shows that you have maintained continuity of thought and are still thinking like a problem solver, not just an applicant.
Crucially, understand the difference between following up on a job application versus following up after an interview. For the initial submission, your follow-up email should be very brief (three or four sentences max), simply confirming receipt and reasserting your interest without demanding an answer. If you have had a conversation with someone directly—even just a quick phone screening—your follow-up must reference that specific interaction to show continuity of thought and respect for the time they already spent with you.
