Cover Letter Writing Services

Transform your introduction into an opportunity. Our tailored cover letters show why you’re the right fit, before your resume is even read.

A strong cover letter opens doors before your resume is even read

Your cover letter is your first chance to make a personal connection with a hiring manager. It is where you turn your qualifications into a conversation. While a resume highlights what you have done, a great cover letter explains why it matters and why you are the right person for the role.

At Otto Resumes, we write professional, persuasive cover letters that speak directly to employers and recruiters. Each letter is customized to your goals, voice, and target positions so you can apply with confidence and stand out from the competition.

Why a strong cover letter still matters

Many professionals believe hiring managers no longer read cover letters. The truth is that more than 60% of recruiters still prefer applicants who include one, and more than 30% say it directly influences their decision to interview.

A well-written cover letter:

  • Creates a personal connection before an interview ever happens

  • Shows effort, communication skills, and motivation

  • Highlights achievements that matter most for the role

  • Complements your professional resume by explaining your “why”

In competitive job markets, this is what makes you memorable.

Our approach to Cover Letter Writing

We believe every client deserves a letter that feels genuine, strategic, and aligned with their professional brand. That’s why each project begins with understanding your story before putting a single word on paper.

Our cover letters are:

  • Custom written — no templates or generic openings

  • Personalized to your target role and company

  • Keyword-optimized to align with your resume and job posting

  • Designed for impact — professional in tone, concise in structure, and authentic in message

Every cover letter is written by a U.S.-based Certified Professional Resume Writer (CPRW) who knows how to capture attention in a few powerful paragraphs.
