Do you use email templates as part of your proofing process?

For the first few years of my career, I had always written each email from scratch. Then, I noticed that I was writing the same thing over and over again and that it was taking me half an hour or longer to do so each time. I was constantly switching back and forth between creative tasks and customer service tasks causing me to take longer to do both parts of my job. Since then I have put in place a few different email templates and short keys that have been fine-tuned and implemented into my design process. My emails are still personal, I edit them to add or subtract information when needed and I add personal notes and greetings for clients I work with often. But now I can send my emails out within minutes and not have to switch out of my creative mindset to do it.
