Tip
Key rules for professional email vocabulary
Use precise terms and standard collocations to keep emails clear and professional.
Use 'subject' to summarize purpose: start with project or action (e.g., "Project X: Budget approval").
Use action verbs for clarity: attach, confirm, review, approve.
Use 'cc' for visibility and 'bcc' for discreet mailing lists.
Label attachments clearly and mention them in the body.
Consistent wording reduces back-and-forth and speeds up responses.
Example
Examples in context
Please find the quarterly report attached.
Could you confirm receipt of this email?
I have cc'd HR so they are aware of the update.
I'll forward the vendor's invoice to accounting.
Tip
Common mistakes to avoid
Avoid errors that can reduce clarity, cause delays, or create confusion in business emails.
Vague subject lines that don't state the purpose.
Mentioning an attachment but forgetting to attach it.
Using CC/BCC incorrectly—this can leak recipients' addresses or cause redundancy.
Overly long paragraphs or unstructured messages that bury the request.
Ambiguous calls to action (no clear deadline or next step).
Quick checklist: clear subject, named attachments, recipient fields correct, one clear action.
