It’s more confident than “I will do my best,” though it doesn’t use the most professional language. Instead, it suggests someone you know can put their faith in you to complete something effectively.

For example, you may use it when messaging a coworker and letting them know you will help them with a project. If they’ve asked you to take on certain aspects of the project, “I won’t let you down” shows that you will do everything you can to get it right.

We think that “I won’t let you down” works best conversationally, so it’s best to avoid it in formal writing. However, it’s more effective than “I will do my best” both formally and informally since it’s much more confident.

Here are a few sentences that will show you how to use it:

Is It Correct to Say “I Will Do My Best”?

“I will do my best” is correct and acceptable in most written cases. However, it is not confident, so it won’t work in formal emails.

For instance, we don’t recommend trying to say “I will do my best” to your boss. After all, it will not fill them with encouragement or confidence that you’ll do a good job. You need to show them that you’re capable, so a different phrase that highlights your skills will work better.

Instead, you may want to stick with “I will do my best” in informal situations. It’s more conversational, making it much better when there’s less pressure to sound professional.

You can also use some of these variations:

  • I will do my best to contribute to the team
