How to write and send an email?

Writing and Sending an Email

Prerequisites

• An email account (e.g., Gmail, Outlook, Yahoo, ProtonMail) with an address in the format [email protected]
• Access via webmail (browser) or an email client/app (Gmail app, Outlook, Thunderbird, Apple Mail)

Anatomy of an Email

• To — primary recipient(s); comma-separate multiple addresses
• Cc — secondary recipients (visible to all)
• Bcc — hidden recipients (invisible to others; use for mass mailings)
• Subject — concise summary of the message (e.g., “Invoice #1042 – Payment Confirmation”)
• Body — the message content
• Attachments — files sent with the message

Step-by-Step Process

1. Log in to your email provider or open your email client.
2. Click Compose / New / New Message.
3. Enter the recipient’s address in the To field — it must be exact (e.g., [email protected]).
4. Write a clear, short Subject line.
5. Write the Body:
   • Greeting (“Hello Sarah,”)
   • Purpose/context in the first sentence
   • Details in short paragraphs or bullet points
   • Closing (“Best regards,” / “Thank you,”) followed by your name
6. Attach files if needed (paperclip icon); most providers limit attachments to 20–25 MB — use cloud links for larger files.
7. Review: check recipient addresses, spelling, tone, and that intended attachments are included.
8. Click Send. The message typically arrives within seconds.

Key Conventions

• Use Reply for the sender only, Reply All only when all thread participants need the response.
• Use Bcc when emailing large groups to protect recipient privacy.
• Avoid all caps (reads as shouting); use plain, professional language.
• Do not put sensitive information in the Subject line.

Programmatic Sending (Python + SMTP)

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

msg = MIMEMultipart()
msg["From"] = "[email protected]"
msg["To"] = "[email protected]"
msg["Subject"] = "Automated Report"
msg.attach(MIMEText("Report body text here.", "plain"))

with smtplib.SMTP_SSL("smtp.example.com", 465) as server:
    server.login("[email protected]", "app_password")
    server.send_message(msg)

Note: Major providers (e.g., Gmail) require an app-specific password or OAuth2 instead of the account password.
