Keep in mind that regulations for use of email and text messaging may require clients to opt-in—meaning they give permission for you to contact them in this way. So, you’ll need to be clear if you plan only to use email or text messages for one-on-one communication during active casework or if you may also use it for other reasons as well, including reminders or promotions for your products or services.
Responding to voicemails is time-consuming. Fortunately, with the right greeting, you might be able to save yourself some hassle. If you don’t have an auto attendant, you can give callers the information they are looking for with your voicemail greeting. Of course, this means that your greeting may be a little lengthy, but that can work in your favor as callers will only stay on the line to leave a message if they still need assistance.

For many businesses and professionals, your voicemail greeting is going to be the first point-of-contact for your customers. This is especially true for service businesses, who often rely on their voicemail to collect information from interested parties.
Be honest...you've been fooled by this one before, haven't you? It goes like this: riiiing, riiing, riiiing "Hey." "Hi, it's Juli what's up?" "Oh. I'm not here right now, leave me a message after the beep". There is actually very little I find more irritating than this voicemail, especially for business. Why do you want to fake out a business opportunity? This voicemail leaves callers feeling embarrassed and you looking foolish.
