Business Email in English: Clear, Confident, Correct

Business email in English is where a lot of professionals quietly lose credibility — too formal, too long, or unclear about the ask. Done well, your email is easy to skim, clear about what you need, and gets a fast reply. Here's how, with reusable templates.

Structure that gets replies

Specific subject, one line of context, the ask, a clear close. Lead with what you need; busy readers decide in seconds.

Formal vs. informal tone

Match the relationship. With a new client, warm and professional; with a close colleague, brief and friendly. Over-formality ('Dear Sir, I am writing to inform you…') sounds dated — aim for clear and human.

Templates for common emails

Keep ready versions for the request, the follow-up, the professional apology, and the polite no. Templates remove hesitation and keep your tone consistent.

The follow-up that isn't annoying

'Hi Sara, just bringing this back to the top of your inbox — any thoughts? Happy to help if useful.' Light, short, and easy to answer.
