By SalaryFor.com – real salaries for all professions
Email is still one of the most important tools for workplace communication. The way you write an email can shape how others perceive your professionalism, attention to detail, and respect for others’ time. Strong email etiquette is especially important when communicating with colleagues and customers, where tone, clarity, and structure matter.
This article outlines best practices and provides professional examples for both internal (colleague-to-colleague) and external (customer-facing) emails.
Emails Between Work Colleagues
Key Principles

I hope you’re doing well. I’m currently updating the quarterly budget report and wanted to ask if you could share the latest figures for your department when you have a moment.
If possible, please send them by end of day Thursday. Let me know if you need anything from me to assist with this.
Thank you,
