Professional Email Etiquette: 15 Rules Every Professional Should Know
By ForgedCV Team
Email Still Matters
Despite Slack, Teams, and other messaging apps, email remains the backbone of professional communication. How you write emails directly affects how colleagues, clients, and recruiters perceive your competence.
1. Write Clear Subject Lines
Bad: "Meeting" / "Quick question" / "Hi"
Good: "Q3 Review — Rescheduling to Thursday?" / "Question about your resume experience section"
Subject lines should tell the recipient exactly what the email is about and what action is needed.
2. Lead With the Ask
Put the most important information in the first paragraph. Busy professionals scan emails — they don't read them. If your request is buried, it will be missed.
3. Keep It Brief
Aim for 3-5 sentences per paragraph. No paragraph should exceed 4 lines on mobile. If you need to communicate more, bullet points are your friend.
4. Use Professional Greetings
Safe options: "Hi [Name]," or "Hello [Name],"
Avoid: "Hey" (too casual for first contact), "To Whom It May Concern" (too formal), "Dear Sir/Madam" (dated)
5. Proofread Three Times
One typo in an email to a recruiter can cost you an interview. Read your email once for content, once for grammar, and once aloud before sending.
6. Reply Within 24 Hours
Even if you don't have an answer, send a brief acknowledgment: "Thanks for this. I'll review and get back to you by Wednesday."
7. Use CC and BCC Intentionally
- CC: People who need to know but don't need to act
- BCC: Use sparingly and ethically
- Reply All: Only when everyone needs to see your response
8. One Topic Per Email
If you need to discuss three things, send three separate emails. This makes it easy to track, search, and reply to individual topics.
9. Sign Off Professionally
Safe options: "Best regards," "Best," "Thanks,"
Include your full name, title, phone number, and LinkedIn profile in your signature.
10. Attachments: Check Before Sending
Always double-check you've attached the file. Name your files clearly: "YourName_Resume_2026.pdf", not "resume_final_v3_FINAL(2).pdf"
11. Avoid Urgency Unless It's Urgent
"ASAP" and "Urgent" lose meaning when overused. Reserve them for genuinely time-sensitive matters.
12. Follow the 3-Email Rule
If a conversation needs more than 3 emails back and forth, it should be a call or meeting. Pick up the phone.
13. Tone Check: Read It Aloud
Written communication lacks tone. Read your email aloud. If it sounds harsh, soften it. "Could you..." instead of "You need to..."
14. Unsubscribe From Clutter
A cluttered inbox creates mental noise. Unsubscribe from newsletters you never read. Archive what you don't need.
15. When in Doubt, Err on Formality
It's easier to loosen up than to recover from being too casual. When emailing someone for the first time, be more formal than you think you need to be.
Your Resume Email Matters Too
When you email your resume to a recruiter, the subject line and brief intro can make or break the first impression. Get it right with ForgedCV.
