Simply exercising good manners when it comes to the receipt of voicemail can go a long way for the success of a business. If a company’s voicemail message is “Your call is important to us,” they should live up to those words by treating each voicemail as a high priority.
Sometimes its just the "Hi, it's me please leave a message" that you want recorded. Transcriptions

It might be a short voicemail message that you’re recording, but you do want to make sure you hit all the bullet points. It also helps to speak eloquently over the phone and that works better when you are prepared with what you’re about to say. You are trying to sell yourself in this message so put your best foot forward. If you practice and write down what you’re going to say, you can get rid of all the awkward pauses, ums, and stumbling over words.
If it works better for you, offer your callers the option to email you, or even send over a text to a VoIP texting app, or even your personal number if you don’t mind. Many people will prefer the ability to quickly text or email, and callers will appreciate the increased level of service.
