The rules for writing formal emails in English
To write a good email in English, don't improvise! Read the following tips to avoid making serious mistakes that could compromise the success of your email from the moment it is received.

Issue
The subject line is the first information that recipients see in an email, and if it is written incorrectly or unclearly, it could push the reader to delete it without even opening it. That is why it is important to give a clear and precise message from the beginning, stating the content or the reason for writing it in two or three words that will catch the recipient's attention.
Style
Unlike many other languages that require long, complex sentences in a formal written context, English is very concise and favors short sentences and simple structure. Make sure to break up your text into two or three paragraphs; this allows the reader to quickly see the key points.
