Emails make the world go round. Well at least they make my inbox round (digital fat joke). Experienced users and admins know you can send emails from Salesforce completely ad hoc or by using email templates.
Email templates support merge fields which lets you place data from your Salesforce records directly into the email you’re sending. This is a great way for sending reminders to users, updates to managers, or notifications to clients. I’ve seen email templates used to send links to customer satisfaction surveys and even quotes & proposals.
With merge fields, Email templates in Salesforce can be very useful. With a little extra work they can also be amazingly flexible.
