No emoji or smiley face anything in professional emails. Sad, but true. {I wish I could insert a sad emoji right here.} Keep everything clear and concise. Write an email like you value the other person’s time. Get to the point. Of course, you still want to communicate effectively, but no need to write a dissertation on the subject.
Tip: If you are a larger business and this is a voicemail that pertains to the general business number, then you want to sound professional and provide as much information as you think is necessary for a potential client. Usually, the company website URL or the company email is a good way to get the customer to contact you through other means.

I have a confession to make: I haven’t recorded a new voicemail greeting since 2014. In the past four years, I (hopefully) have become more articulate, poised, and self-assured. But hear my voicemail recording, and you’d think I was still new to the work world, a little unsure of myself — and probably not an authority. Obviously I need toupdate it. And if you haven’t changed your voicemail greeting in over a year, you’re likely in the same boat. After all, a professional voicemail recording boosts your credibility, makes you seem more competent, and encourages whoever’s listening to it to continue the relationship. A relatively unprofessional one — like mine, for instance — does the opposite: It encourages prospects, recruiters, and potential connections to run in the other direction. With that in mind, I’ve written 18 unique voicemail greetings for every situation. Pick your favorite, practice a few times, then record your new voicemail.
The last few years have seen a huge rise in the use of automated voicemails and auto-attendant greetings. This has been especially true for the business sector, where professionals should record friendly and polite voicemails to greet their customer callers.
