Text/Voice/Email autoresponders/followup?

[Kenneth E.]

Does anyone use or know of a good service that offers all three (Text/Voice/Email) autoresponder?

For example, I understand its possible to have a prerecorded voice message from yourself and use it to do a mass followup to all of your previous callers, plus it goes straight to their voicemail and doesnt bother them with ringing.

Following up is important but I dont always have time so Im looking for some electronic ways of doing it.
