It does not benefit you to not follow the federal Can Spam act. Not only can you have a financial penalty if prosecuted, but you can waste time and money trying to send to a spammy list.
If your e-newsletter list has been created by getting email addresses off of websites, from organization directories, or harvested from publications you read or subscribe to you are in violation of the federal Can Spam act. Your names fit into the “harvested” category. Many clients simply say “no one will catch me” and they decide to play the odds. Yes, it is true they may not be caught, but they may end up spending more money than they bargained for in trying to email to this type of list.
In several cases clients that came to us did not truthfully divulge where their large 6,000 member lists had come from. In both cases they paid money to us to set up subscriber accounts with a service to use to send out their mailings. One client purchased over 10 hours of additional time to scan his printed subscriber lists to create a digital version. In each cases after the first mailing the professional e-newsletter sending services shut down the accounts. One closed the account outright, and two forced these large lists to become double opted in. This means that a confirmation message was sent out and anyone who did not respond would never receive mailings again. Out of the nearly 6,000 that were on these lists under 100 responded that they wanted the mailings. So in essence with a spammy list the customer just threw money out the window in trying to send email to a harvested name list.
The lesson to be learned here is that a spammy list does not do you any good. You may end up spending more money trying to send to this type list and still end up being shut down. It is simply not worth the effort or risk.
