Query Letter Mistakes to Avoid: A Comprehensive Guide

Query letters are a crucial part of the publishing process for aspiring authors. They are the first impression that agents and editors have of a manuscript, and can make or break a writer’s chances of getting published. However, writing a successful query letter for a literary agent is not an easy task. There are many mistakes that writers can make that will instantly turn off agents and editors, and prevent them from even considering the manuscript.

One of the most common mistakes that writers make in their query letters is not following submission guidelines. Agents and editors receive a large volume of queries, and they often have specific requirements for how they want submissions to be formatted and presented. Failing to follow these guidelines can make a writer look unprofessional and careless, and may result in their query being rejected without even being read.

Another mistake that writers often make is not doing enough research on the agents and editors they are querying. Each agent and editor has their own preferences and interests, and writers should tailor their queries to match those preferences. Sending a generic query letter that doesn’t show any knowledge of the agent or editor’s tastes is a surefire way to get rejected. By doing their homework and customizing their queries, writers can increase their chances of getting noticed and ultimately getting published.

Understanding the Purpose of a Query Letter

A query letter is a vital tool in a writer’s arsenal when it comes to getting their work published. It is a one-page letter that is sent to literary agents or publishers to convince them to represent or publish the writer’s work. The primary purpose of a query letter is to persuade the agent or publisher that the writer’s work is worth their time and effort.

In writing a query letter, the writer should aim to make a good first impression, as the letter is often the first point of contact between the writer and the agent or publisher. The letter should be well-written and free of any spelling or grammatical errors, as these can make the writer appear unprofessional and may result in the letter being rejected.

The tone of the query letter should be professional and confident. It should convey the writer’s enthusiasm for their work and their confidence in its potential. The writer should also be clear about the genre of their work and its target audience, as this will help the agent or publisher determine whether the work is a good fit for their list.

Common Query Letter Mistakes

When it comes to writing a query letter, there are several mistakes that writers commonly make. These mistakes can hinder their chances of success with literary agents and publishers. Here are some of the most common query letter mistakes to avoid:

1. Failing to Read Submission Guidelines

One of the biggest mistakes that writers make when submitting query letters is failing to read the submission guidelines provided by the literary agent or publisher. Each agent or publisher has their own guidelines for how they want to receive query letters. Failing to follow these guidelines can result in an automatic rejection.

2. Poor Formatting and Appearance

Another common mistake is submitting a query letter with poor formatting and appearance. This includes using all caps, colored or esoteric fonts, or including quotes in the signature. It’s important to ensure that the letter is easy to read and looks professional.

3. Too Much Information

Many writers make the mistake of including too much information in their query letter. It’s important to keep the letter concise and to the point. Agents and publishers are busy, and they don’t have time to read a long letter that is filled with unnecessary information.

4. Lack of Personalization

Another mistake is failing to personalize the query letter. Agents and publishers want to feel that the writer has done their research and is genuinely interested in working with them. Failing to personalize the letter can make it seem like the writer is simply sending out a generic letter to multiple agents or publishers.

5. Poor Writing Skills

Finally, poor writing skills can also be a major mistake when it comes to query letters. The letter should be well-written, free of errors, and demonstrate the writer’s ability to write professionally. If the letter is poorly written, it can be an automatic rejection.

By avoiding these common query letter mistakes, writers can increase their chances of success with literary agents and publishers.

Language and Grammar Pitfalls


Spelling and Typos

One of the most common mistakes that writers make when writing query letters is not proofreading their work. Typos and spelling errors can be a major turn off for agents and publishers. A single mistake may not necessarily lead to rejection, but a query letter that is riddled with errors can give the impression that the writer is unprofessional and careless.

To avoid falling into this trap, writers should take the time to proofread their query letters multiple times. They can also use tools such as spell-checkers and grammar-checkers to catch any errors that they may have missed. It is also a good idea to have someone else read over the letter to catch any mistakes that the writer may have overlooked.

Appropriate Language Use

Using appropriate language is another important aspect of writing a successful query letter. Writers should avoid using overly casual or slang terms, as this can make them appear unprofessional. They should also avoid using overly complicated language, as this can be difficult for agents and publishers to understand.

Instead, writers should aim for a tone that is clear, concise, and professional. They should use language that is appropriate for the genre and audience that they are writing for. For example, a query letter for a children’s book should use language that is appropriate for children.

By paying attention to these language and grammar pitfalls, writers can avoid common mistakes that can lead to rejection. A well-written query letter that is free of errors and uses appropriate language can help writers stand out from the crowd and increase their chances of getting published.


In conclusion, writing a query letter is a crucial step in getting a publishing deal with a traditional publisher. However, it is important to avoid common mistakes that can lead to rejection. By following the tips outlined in this article, writers can increase their chances of success.

One of the most important things to keep in mind is to read the submission guidelines of the agent or editor carefully. Failing to do so can result in immediate rejection. Additionally, writers should avoid misspelled words, grammatical errors, and poor formatting.

Another mistake that writers should avoid is making exaggerated or false claims about their book. This can lead to a loss of credibility and can make the writer seem unprofessional. Instead, writers should focus on highlighting the unique aspects of their book in a clear and concise manner.

Finally, writers should remember that the query letter is only the first step in the process of getting a publishing deal. Even with a well-crafted query letter, it may take time and persistence to secure a book deal with a traditional publisher. By avoiding common mistakes and staying committed to the process, writers can increase their chances of success.
