Understand E-mail: Parts, Uses and Etiquette
1. Meaning. E-mail is a method of sending and receiving written messages, documents, pictures and other files from one computer or mobile device to another over the internet, using an e-mail address. It is the cheapest and fastest means of sending written messages electronically.
2. Parts of an e-mail
- From: the sender's address.
- To: the main recipients.
- Cc (carbon copy): others who should be informed; every recipient can see who is in Cc.
- Bcc (blind carbon copy): recipients hidden from the others; used for mass mailing and privacy.
- Subject: a brief, clear topic.
- Body: greeting, message and closing.
- Attachments: files sent with the message.
- Signature: name, designation, firm and contact details.
Messages are stored in the Sent folder and the receiver's Inbox, so they form a retrievable record.
3. Uses in business
- Correspondence with customers and suppliers: enquiries, quotations, orders, confirmations, complaints and replies.
- Internal communication: circulars, notices and instructions to branches.
- Sending documents as attachments: invoices, contracts, reports, catalogues.
- Marketing: newsletters and offers.
- Recruitment: applications, interview and appointment letters.
- Record and evidence of agreements, with date and time.
- Coordination across time zones, since messages wait in the inbox.
4. Advantages. Speed; low cost; reaches many people at once; attachments; dated record; available round the clock; saves paper.
5. Limitations. Needs internet and devices; viruses, spam and phishing; security and privacy risks; misunderstanding because tone is missing; information overload; unsuitable for very confidential or emotional matters.
6. Etiquette. Clear subject line; polite greeting and close; brief message in short paragraphs; check spelling; avoid writing in capital letters, which reads as shouting; mention and check attachments; use Cc and Bcc carefully; reply promptly; add a signature.
7. Cc versus Bcc. Cc is open: everyone sees it. Bcc is hidden: others do not see those addresses.
