What is Email and Why Do We Need It?
The Basics Everyone Should Know
Email (Electronic Mail) is simply a way to send messages, documents, and files from one person to another through the internet. Think of it like posting a letter, but instead of using physical post offices, we use digital "post offices" called email servers.
Why is email still important in 2025?
- Professional Communication: Every business relies on email for formal communication
- Documentation: Unlike phone calls, emails create a permanent record
- File Sharing: Easy way to send documents, images, and other files
- Global Reach: Instant communication across continents
- Cost Effective: Much cheaper than traditional mail or international phone calls
Real-World Impact
In India, email has transformed how we:
- Apply for jobs (sending CVs and cover letters)
- Communicate with clients and colleagues
- Receive important notifications from banks, government, and services
- Conduct business transactions and maintain records
Understanding Email as a Service (EaaS)
What Does "As a Service" Mean?
Instead of companies setting up their own email systems (which requires servers, technical staff, and maintenance), they can use Email as a Service. This means:
Traditional Approach (Before EaaS):
- Company buys servers
- Hires IT staff to maintain them
- Handles security, updates, and troubleshooting
- Bears all costs and risks
Email as a Service Approach:
- Company pays a monthly/yearly fee
- Service provider handles all technical aspects
- Automatic updates and security
- 24/7 support included
- Scales easily with business growth
Key Benefits of EaaS
- Reduced IT Burden: No need for specialised technical staff
- Cost Predictability: Fixed monthly costs instead of large upfront investments
- Reliability: Professional providers offer 99.9% uptime guarantees
- Security: Enterprise-grade security without the complexity
- Scalability: Easy to add or remove users as needed
How Email Actually Works
The Journey of an Email Message
Let's trace what happens when you send an email from Mumbai to your friend in Delhi:
Step 1: Composition You write your email using an email client (like Gmail, Outlook, or your phone's email app)
Step 2: Sending
- Your email client connects to your email provider's server (SMTP server)
- The server checks your credentials and accepts the message
Step 3: Routing
- Your provider's server looks up the recipient's email domain
- It finds the recipient's email server and establishes connection
Step 4: Delivery
- The message is transferred to the recipient's email server
- The server stores the message in the recipient's mailbox
Step 5: Retrieval
- When your friend checks email, their client downloads the message
- They can now read, reply, or forward your email
Key Technical Terms (Simplified)
SMTP (Simple Mail Transfer Protocol): The system that sends emails POP3/IMAP: Systems that retrieve emails from servers DNS (Domain Name System): Like a phone book that helps find email servers Webmail: Accessing email through a web browser Email Client: Software that manages your emails (Outlook, Apple Mail, etc.)

Email Management Fundamentals
Organising Your Inbox
The Folder System Approach:

├── Action Required
├── Waiting For Response
├── Reference Materials
├── Projects
│ ├── Project A
│ ├── Project B
│ └── Project C
├── Personal
└── Archive
The Label/Tag System (Gmail style):
- @Action: Emails requiring action
- @Waiting: Waiting for someone else's response
- @Today: Must be handled today
- @This Week: Can be handled within the week
- Projects: Project-specific labels
Email Processing Best Practices
The 2-Minute Rule: If an email can be handled in under 2 minutes, do it immediately. Otherwise, file it appropriately for later action.
Daily Email Routine:
- Morning (15 minutes): Check for urgent emails, respond to quick ones
- Midday (30 minutes): Process emails, file them appropriately
- End of day (15 minutes): Clear inbox, prepare for tomorrow
Weekly Email Maintenance:
- Clean up folders and labels
- Delete unnecessary emails
- Archive old emails
- Review and update email rules/filters
Creating Effective Email Rules and Filters
Common Filtering Scenarios:
Automatic Filing:
If email from: boss@company.com
Then: Label as "Important" and mark as important
Spam Reduction:
If email contains: "lottery winner" OR "prize money"
Then: Delete automatically
Project Organisation:
If subject contains: [Project Alpha]
Then: Label as "Project Alpha" and skip inbox
Newsletter Management:
If email from: newsletters@*
Then: Label as "Newsletters" and mark as read
