One of the biggest mistakes for any follow-up email is not including a strong call-to-action. Leaving the email open-ended with phrases like “let me know what you think” or “keep in touch” aren’t a strong enough incentive for your client to respond. You’re more likely to get a response when you ask pointed questions like “What day and time works best for you next week to discuss this further?” or “Based on the deadline that you mentioned, you’ll need to start our service by the end of this month—do you have 30 minutes to sit down and chat later this week?”
