"Email is a wonderful thing for people whose job is to fill other people's inboxes. It's a terrible thing for people whose job is to do actual work." - Leo Babauta
The Problem with Most Emails
Most emails fail because they:
- Have vague or missing subject lines
- Buried the main request deep in the text
- Included unnecessary information
- Lacked clear next steps
- Were written from the sender's perspective, not the reader's
The PEEL Framework for Effective Emails
Purpose
Start every email by stating your purpose clearly. One sentence should answer: Why am I writing this email?
Essential Information
Include only what the reader needs to respond. Cut anything that doesn't directly support your purpose.
Expectation
Be explicit about what you want. Do you need a decision? Feedback? Action? State it clearly and early.
Length
Respect the reader's time. Shorter emails get faster responses. If your email exceeds 5 paragraphs, consider if it should be a meeting.
Crafting the Perfect Subject Line
Your subject line is your first impression. It determines whether your email gets opened, ignored, or archived. A good subject line:
- Is specific: "Q4 budget approval needed by Friday" not "Budget"
- Creates urgency when appropriate: "[Urgent] Server down"
- Uses keywords the reader will search: Include project names, dates, or actions
- Avoids ALL CAPS and excessive punctuation
