Do you use email in your business? The CAN-SPAM Act, a law that sets the rules for commercial email, establishes requirements for commercial messages, gives recipients the right to have you stop emailing them, and spells out tough penalties for violations
Rather than sending email to a large group of email addresses from your email account hosted at Carolina Digital it is much better to use on of the many services that specialize in sending bulk email. Sending bulk email from your Carolina Digital (legacy CAROLINANET) is a violation of our acceptable usage policy. Additionally your outbound email sending is limited to the number of emails you can send during a period of time. Email from your Carolina Digital account is intended for one-to-one emails to individuals you are doing business with and not for UBE (unsolicited bulk email). No matter who you send email to you must have their permission. This is referred to as Confirmed Opt-In.
Here are just a few services you should consider using and if your email list is small and you don't send with regular frequency you might find a plan that is free and completely CAN SPAM compliant.
