Then, the email would say: “Ms. Smith, Fluffy’s next appointment is on Monday the 12th at 1:00. Please click to reply/confirm this appointment at [name of practice]. If we do not hear from you in the next five business days, this slot may be given away. Thank you.” "Does that mean the number of incoming calls and voice mails are also in massive decline in the world of veterinary medicine in favor of electronic communication? Probably not."
As probably know, a professional voicemail greeting can make or break leaving a great impression. However, it all starts with your voicemail script.

If you choose to do this, make sure you develop a discipline. If you say you return calls within 2 hours, it needs to be 2 hours. Delivering on what you promise is what’s going to make your customer service stand out when it comes to busy times and people reaching your voicemail.
When you leave a voicemail do not use your full name because that immediately raises a red flat that you are a salesperson making a cold call. Instead, say your first name only followed by your company name. This will make your customer feel that you are much more familiar with each other than you really are. Saying your last name would defeat the whole purpose of demonstrating familiarity.
