In today’s professional world, emails are a crucial form of communication. They’re often the first (or only) impression we make on colleagues, clients, and managers, so clarity and professionalism are key. However, even small grammar mistakes can lead to misunderstandings or cast a negative light on your communication skills. Here are some of the 20 most common grammar errors to avoid in professional emails—and tips on how to prevent them.
20 Grammar Mistakes to Avoid in Professional Emails in Costa Rica
1. Confusing «Your» and «You’re»
The Mistake: Mixing up «your» (possessive) and «you’re» (contraction for «you are»).
Example:
- Incorrect: «I hope your happy with the results.»
- Correct: «I hope you’re happy with the results.»
How to Avoid It: Read the sentence aloud and substitute «you are» for «you’re.» If it makes sense, use «you’re»; if it doesn’t, use «your.»

Example:
- Incorrect: «Their going to meet us there at the office.»
- Correct: «They’re going to meet us there at the office.»
How to Avoid It: Remember:
- There indicates a location or introduces a subject.
- Their shows ownership.
- They’re means «they are.»

The Mistake: Confusing «its» (possessive) with «it’s» (contraction for «it is» or «it has»).
Example:
- Incorrect: «The company is expanding it’s reach globally.»
- Correct: «The company is expanding its reach globally.»
How to Avoid It: Substitute «it is» in place of «it’s.» If the sentence makes sense, use «it’s»; if not, use «its.»

4. Subject-Verb Agreement Errors
The Mistake: Using a singular verb with a plural subject, or vice versa.
Example:
- Incorrect: «The team are meeting tomorrow.»
- Correct: «The team is meeting tomorrow.»
How to Avoid It: Make sure the subject and verb match in number. A singular subject takes a singular verb, while a plural subject takes a plural verb.

5. Overusing Commas or Using Them Incorrectly
The Mistake: Adding too many commas or omitting them where needed.
Example:
- Incorrect: «We’re launching the product next week, and we’re hoping for a great response.»
- Correct: «We’re launching the product next week and hoping for a great response.»
How to Avoid It: Use commas to separate ideas and lists, but be cautious not to overdo it. A good rule is to read your sentence aloud; if you pause naturally, a comma might be necessary.

6. Misusing «Affect» and «Effect»
The Mistake: Confusing «affect» (verb) with «effect» (noun).
Example:

How to Avoid It: Remember, «affect» is usually a verb (an action), while «effect» is typically a noun (a result).

7. Misplaced Apostrophes in Plurals
The Mistake: Adding an apostrophe to make a word plural.
Example:

8. Writing in Passive Voice Too Often
The Mistake: Using passive voice, which can make sentences sound indirect or weak.
Example:
- Passive: «The report was completed by the team.»
- Active: «The team completed the report.»
How to Avoid It: Aim to use active voice in professional emails. Active voice is more direct, concise, and easier to read.

The Mistake: Confusing «then» (indicating time) with «than» (used for comparisons).

How to Avoid It: Remember that «than» is used for comparisons, while «then» refers to sequences in time.

10. Sentence Fragments or Run-Ons
The Mistake: Writing incomplete sentences or combining too many ideas in a single sentence.
Example:
- Fragment: «In case you need help with the report.»
- Run-On: «I worked on the project all day we are almost finished.»
How to Avoid It: Make sure each sentence has a subject and verb. For run-on sentences, split them up or use commas and conjunctions to clarify ideas.

11. Misusing «Me,» «Myself,» and «I»
The Mistake: Using «I» or «myself» when «me» is correct, or vice versa.
Example:
- Incorrect: «Please send any questions to John or I.»
- Correct: «Please send any questions to John or me.»
How to Avoid It: If you’re unsure, try removing the other person’s name from the sentence. For example, «Please send any questions to I» sounds wrong, so «me» is correct. «Myself» should only be used when you’re both the subject and object, as in «I did it myself.»

12. Confusing «Who» and «Whom»
The Mistake: Using «who» (subject) and «whom» (object) interchangeably.
Example:
- Incorrect: «To who should I address the letter?»
- Correct: «To whom should I address the letter?»
How to Avoid It: Use «who» when referring to the subject of a sentence and «whom» for the object. A helpful trick is to substitute «he» or «him.» If «him» fits, use «whom»; if «he» fits, use «who.»

13. Incorrect Placement of “Only”
The Mistake: Misplacing “only” in a sentence, which can change the meaning.
Example:
- Incorrect: «I only sent the report yesterday.»
- Correct: «I sent the report only yesterday.»
How to Avoid It: Place “only” immediately before the word or phrase it modifies to avoid confusion. Re-read the sentence to ensure it conveys the intended meaning.

The Mistake: Choosing the wrong preposition, which can lead to awkward or unclear sentences.
Example:
- Incorrect: «She was concerned about if the project would be completed.»

How to Avoid It: Common preposition errors include «of» instead of «about,» «in» instead of «on,» etc. If you’re unsure, double-check or rephrase the sentence for clarity.

15. Using Too Many Exclamation Points
The Mistake: Overusing exclamation points, which can come across as unprofessional or overly emotional.
Example:
- Incorrect: «Thank you for your help!!!»
- Correct: «Thank you for your help.»
How to Avoid It: In professional emails, limit yourself to one exclamation point if necessary, and only when it adds value. Overusing them can make your message seem less formal.

16. Incorrectly Capitalizing Words
The Mistake: Randomly capitalizing words that aren’t proper nouns or the start of a sentence.
Example:
- Incorrect: «I’m Excited to meet the Sales Team.»
- Correct: «I’m excited to meet the sales team.»
How to Avoid It: In professional emails, only capitalize proper nouns and titles when they appear before a person’s name (e.g., «Director of Marketing»). When in doubt, keep it lowercase to maintain a clean, professional tone.
