YouMail's Smart Greeting is an automatic, intelligently formed voicemail message that uses customizable bits of information that we know about both you and your callers to give them a friendly, personalized experience.
For example, if your caller is named John, and your name is Mike, the Smart Greeting will play:
"Hi John, Mike is currently unavailable. Please leave a message."
How do you know the names of my callers?
The most certain way to help us identify your caller is to create a contact that contains both their name and phone number.
In addition to your contacts, YouMail also uses a large directory with the caller ID information for hundreds of millions of callers. If you don't have a contact but we can find the name of your caller in our database, we'll greet them with that name, even if it is not the correct name.
Sometimes these databases have the owner of the phone line (i.e. the person who pays the bill), so until you create a contact for someone, we might think that their spouse or parent is the one calling you. Syncing your phone's contacts to YouMail helps avoid that.
Levels of Smart Greeting
The basic Smart Greeting is a more casual greeting and only uses your first name, phone number, or the phrase "the YouMail subscriber".
Users subscribed to the YouMail Professional plan have access to a more advanced Smart Greeting which is more formal and will use your full name and company name. For example:
"Hi John, you've reached Mike Smith of Acme Inc, who is currently unavailable..."

Transcribed by YouMail
YouMail offers voicemail transcriptions but one of the toughest barriers between us and perfect accuracy are unclear messages. To fix this, we end the Smart Greeting with a phrase:
"Please speak clearly. This voicemail is being transcribed by YouMail."
This encourages the caller to leave a more clear and understandable message and you receive a transcription with the highest level of accuracy. If you want to remove this phrase from your greeting, click here.
