Electronic mail, most commonly abbreviated email or e-mail, is a method of exchanging digital messages.
An electronic mail message consists of two components, the message header, and the message body, which is the email's content. The message header contains control information, including, minimally, an originator's email adrress and one or more recipient addresses. Usually additional information is added, such as a subject header field.
Emails are a fast way to communicate for business and pleasure. In this post you'll find useful hints and tips to write better emails in English.

Email Features

There are many features that are included in emails; here I will highlight just a few important ones.

Spelling: Always proofread before sending: spelling, punctuation and grammar. [F7]

Insert: Since emails are filtered here are a few tips regarding attachments and links:

• Keep file sizes small.
• ZIP or PDF attachments (exe, jpg, xls, doc are sometimes considered spam).
• When replying, do not resend attachments again.
• Use links whenever possible to files that are stored online or in shared folders.

Options: If the email is very important, under options request a read receipt, this way you can ensure the email has arrived at its destination.

Reply to All: Stop and think before hitting reply to all sometimes you may just need to hit reply.
