To increase your chances of closing the deal, you need to maintain contact and communication with your prospects until they are ready to buy. After your demo, immediately send a thank-you email to express appreciation, summarize key points and benefits, and restate the call to action. Also attach any relevant materials that can help them remember your story. Ask for feedback through surveys, phone calls, or emails to gauge their level of interest, satisfaction, and understanding. Provide value by sharing useful and relevant information such as articles, blogs, podcasts, or webinars that can help them learn more about your product, industry, or topic. Showcase your product's success and impact by using stories, testimonials, or case studies. Nurture the relationship with your prospects by building rapport, trust, and credibility through social media, newsletters, or events. Stay in touch and personalize communication to show interest.
