12 ready email templates for entrepreneurs: sales, investors and customers

Email is still one of the most important tools in entrepreneurs' communication with customers, investors and partners. A short, well-written email opens the meeting door, while a long, generic message is deleted unread. In this guide we share the 12 email templates entrepreneurs need most and the principles of effective email. Fill the bracketed fields with your own information and personalise each message to the recipient.

6 principles of effective email

1. Be short: 5–8 sentences are often enough.
2. A clear subject line: It should say what you want or what is valuable.
3. Personalise: Start with an observation specific to the recipient.
4. One ask: A clear, small next step (e.g. a 15-minute call).
5. Value first: Highlight the other side's gain.
6. Follow up: If there is no reply, send a short reminder after 3–5 days.

Common mistakes

• Long, generic, company-focused messages
• More than one ask
• Bulk sending without personalisation
• Not following up, or following up too often
• Sending bulk commercial email without consent (may breach regulations)
• Typos and vague subject lines
