Hi TerryTen,
Set up a mailing list that you manage, but has the contact information of the company that should be contacted in the message body.
Do you have your own mail server for creating the mailing lists, the actual messages, managing bounces, and handing bounces and blacklistings?
If not you can try a service such as
MailChimp that will let you send each month for free depending how big your lists are.
More mailing list options are listed on our
Email Marketing Reviews page.
Please let us know if you need any more information.
