12. "Hi, you've reached [company]. We're available by phone from [hour] to [hour] [time zone] Monday through Friday [optional: and from hour to hour on the weekends]. You can also contact us by going to our website, [URL], and live-chatting or emailing us. If you'd like us to call you back, please leave your name and number after the tone."
But the key to success here is knowing what to say on the second and third voicemail/email attempts BEFORE picking up the phone.

Approach voicemails with a scientific outlook, and score each one. Create a score sheet with a rating system that addresses the following: Would you save that voicemail? Would you return that call? Would you return that call right away? Are you missing the basics (alternative phone number, optimal ways to get in touch, a fallback person to call)? Did you craft it or wing it?
With Visual Voicemail, you can see a list of your messages and choose which ones to listen to or delete. Learn how to set up and transfer your existing voicemail. Create a voicemail password, then tap Done. Enter your password again to confirm it, then tap Done. Select Custom or Default. If you choose Custom, you can record a new greeting. Go to the Phone app, then tap the Voicemail tab. Tap Set Up Now. Enter your password,* then tap done. Record a custom greeting or use the default greeting, then tap Save.
