20 per day is nothing, you won't get blacklisted at all. A standard email account could be used for that like Gmail or Hotmail. Create a distribution list and obey the sending limits:
* Maximum of 100 people at a time with Gmail via POP or IMAP clients
* Maximum of 500 addresses in your To:, Cc:, and BCC: fields with Gmail via web browser
* Failed deliveries due to large number of broken e-mails (25?)
* Nine-month long stagnant account (permanently disabled account)
