One thing to remember is that it’s not all about you. Yes, you need to recognize what makes your life easier, but you need to make sure you know what makes your customers’ lives more difficult in order for you to determine what kind of actionable voicemail greeting you need them to hear. This, of course, will make your life easier too.
Remember to watch out for ambient noise on your end of the call as well. Train signals, traffic, or even outside conversations can be very distracting to your callers and project an unprofessional image. Don’t forget the beep. Every millisecond – yes, millisecond – between the end of your greeting and the beep is time callers could potentially drop the call. That’s why the anticipated beep should sound the moment your greeting is finished. Leaving lengthy, silent gaps may cause your customers to wonder if they’ve been disconnected. Don’t give them the opportunity to hang up waiting to hear that affirmative tone. Check and then recheck your greeting. After you complete your outgoing voicemail message, play it back to verify you’ve said everything you intended to say. Then take it a step further and dial in to experience the greeting for yourself, and be mindful to contemplate the greeting from the customer’s perspective.
