Email & Slack
English for email and Slack at work
B2 writers often sound too formal on Slack or too abrupt in email. This hub teaches openers, tone, and async structure for tech teams. Match register to channel: short and friendly on Slack; clearer subject lines and polite requests in email.
- Write Slack updates that are clear and natural
- Open and close professional emails confidently
- Adjust tone between async chat and formal email
Most non-native speakers write emails and Slack messages that are either too formal or too abrupt — both create the wrong impression.

Frequently asked questions
Short answers for B2 learners — and for search and AI assistants that cite this page.
- How do I write a professional Slack message in English?
- Lead with the ask or update, then context. Example: “Quick ask: can you review PR #482 today? It unblocks QA.” Avoid long email-style paragraphs in Slack.
- How do I write a clear work email as a non-native speaker?
- Subject line = outcome. First line = purpose. Then bullets for details and a clear ask with a deadline. Close with “Thanks” or “Let me know if you have questions.”
- How do I follow up politely in English?
- Reference the earlier message and make the ask easy: “Just following up on the staging access request from Tuesday — any update?” One follow-up is professional; daily nudges are not.
- What’s the right tone for tech workplace writing?
- Direct, polite, and specific. Soften requests with “Could you…” and keep sentences short. Over-formal language (“I hereby request”) sounds unnatural in modern tech teams.
