For instance, you may use it when emailing your boss. It tells them you’ll do your best without sounding insecure or unsure of your own ability.

Instead, it shows you’ll be proactive and do what you can. It will fill your boss with confidence and show them that you’re serious about trying to get a task done.

We recommend this email example if you’re still unsure:

Let me see what I can do with this project. I’ll let you know when I’ve completed it, and you can review my work.

2. I’ll Show You What I Can Do

There’s nothing wrong with backing yourself in a work environment. It’s good to have confidence in your own abilities. It will show your employer how serious you are about the job and what you can bring.

That’s where “I’ll show you what I can do” comes in. It’s a great phrase in a professional setting. After all, it shows you are convinced you’ll be able to help someone and they’ve come to the right person.

Here’s a great sample email to show you how it works:

Dear Ms. Stevenson,

I’ll show you what I can do. I’ll try to keep up the good work I’ve been putting in and return this project completed.

Best wishes,
Kimberley Burner

3. I’m Happy to Assist You However I Can

You never know what someone might ask you. So, you might be unable to help the recipient if they ask you for something outside your range.

Nevertheless, you should still appear helpful and positive when someone comes to you in a formal email.

“I’m happy to assist you however I can” is a positive phrase to use here. It shows you’ll do your best to help someone, even if you don’t think you can. It works best when emailing customers who have come to you to ask for assistance.

4. What Can I Do to Help You?

You don’t just have to make statements when demonstrating your abilities. It’s also good to ask a question such as “what can I do to help you?”

After all, this takes the pressure off you. Instead of trying to offer your services and figure out what someone wants, you can ask them directly what they need.

It’s a great way to ensure you’re on the same page and you can do something to help them.

This example should help you understand more about it:

Dear Judy,

What can I do to help you? Is there anything you need right now? I’ll happily find the best solution to help you here.

All the best,

5. Let Me Do What I Can for You

“Let me do what I can for you” is excellent to include in business emails. Many times, someone might come to you for help. This phrase is a great way to show them your willingness to offer it.

Generally, this works best when emailing customers. It shows that you care about looking after them and answering their queries. The more confident you are in your ability to find answers, the more reliable you’ll appear to them.

We also recommend the following email sample:

Dear Aimee,

Let me do what I can for you. I can’t make any promises, but I may have an answer by the end of the day.

Best wishes,

6. I Will Help You

The more confident you are in an email about your skills, the more reliable people will see you. That’s why “I will help you” is such a useful phrase here. It shows you “will” have what it takes to help someone.

Of course, you risk being unable to assist someone when they ask for it. However, we still recommend using this to fill the recipient with confidence in you.

For instance, you may use it to email clients. It shows you will do what you can to help them.

This email example should help you understand it better:

Dear Ms. Pilfer,

I will help you to the best of my ability. Also, I’d like to invite my coworker to join us, as they know more about this.

Best wishes,

7. Please Leave It With Me

Why not try “please leave it with me” when someone has asked you for help? It shows you’ll try to find an answer that might help them. You might not find anything relevant, but at least you’re willing to try.

Also, using “please” is a very polite way to start a formal email, making it excellent when talking to clients. It shows you respect them and will do what you can to appease them.

Here’s a great example to help you:

Dear Samuel,

Please leave it with me for the time being. I will figure out the best course of action before we continue.

All the best,
Hughie Stanson

8. I Will Give It My All

You can also say “I will give it my all” instead of “I will do my best.” It’s a great way to show that you will do everything possible to complete a task.

However, the implication here is that you might not be able to achieve something. Still, it shows willingness and enthusiasm, making it useful in formal emails.

It also shows that you will not quit on a task easily. “Give it my all” suggests you will keep working at something until you figure out what you’re supposed to do.

Perhaps this example will also help you understand it:

Dear Benjamin,

Of course, I will give it my all. I cannot make any promises about the quality of the work, but I have passion for it.

Nobody likes a quitter. And many workplaces look to hire employees who are willing to go above and beyond for their clients. That’s where “I won’t quit until this is finished” comes in.

It’s a great phrase to include when emailing clients. It shows you’re happy to do everything possible to help answer someone’s query.

“I won’t quit” is a very enthusiastic phrase showing that you’re not going to give up on someone. It will often make your clients feel special and like they can rely on you for more help in the future.
