When writing a prospecting email, you should consider your email formula. The BRIEF formula is an effective structure for this purpose. BRIEF stands for Break the ice, Reveal the reason, Indicate the evidence, Encourage the action, and Finish with a flourish. To break the ice, start with a personalized and relevant opening line that shows you've done your research or use a common connection or referral. Then explain why you're emailing them and what's in it for them; include a clear and compelling value proposition and benefit statement. Offer proof or credibility that supports your offer with a testimonial, case study, or statistic. Ask for the desired action and make it easy to take it with a clear and specific call to action and link or button. Finally, end with a polite and positive closing line that reinforces your value and builds rapport. The BRIEF formula can help you write prospecting emails that are concise, clear, and compelling, avoiding common mistakes like being too vague, too long, too pushy, or too boring.
