Hi Sir
to Write a Perfect Professional Email in English , you need to Begin with a greeting , because It's important to always open your email with a greeting , such as "Dear Ahmed,". Depending on the formality of your relationship, or "Dear Mrs. Ilham," also if the relationship is more casual, you can simply put, "Hi Karima," And If you’re contacting a company, you may write "To Whom It May Concern:".
Use a descriptive subject line , Say what the email is about in a few words like "Meeting at 10am about pay rise" 
Starting your email :
Your first sentence should tell the reader what your email is about like :

1. Replying to a previous email

Thanks for the information.
Thanks for your phone call.
....

2. Giving brief updates

Just a quick note to tell you…
Just a quick note to let you know…
...

3. Referring to an attachment

Take a look at the attached file.
......

4. Changing plans

Sorry, but I can't make the meeting tomorrow.
Sorry, but I won't be able to come next week.

........
If you have more than one reason for writing, give each reason its own paragraph. It doesn't matter if your paragraph is only one line long.
try to Keep your emails short , keep to only one point in each email , and Write simple, like writing short sentences rather than long ones and make sure your reader knows what to do next..
and finally , Sign with your full name.
And
Check your email before you send it.
