As an educator, I have talked about email etiquette many times, particularly regarding follow-up and using the three-sentence solicitation as the center of your messaging. Subject lines are important. The language you use is important. But what about the sign-off? Most of us keep things fairly simple, but a slight change could get you a much higher response rate.
I would recommend checking out this article on Inc. on how a small adjustment to your sign-offs will get you more responses, sometimes up to 60% more often than signing “Sincerely” or “Regards.” Demonstrating gratitude will prompt a prospect to get back to you quicker and keep the correspondence going, which is not only a bonus, but essential during these uncertain times.
