I have received information from a trusted maketing contact that a system called GroupsMailer should work. I am a little sceptical though, well I am always a little sceptical to new systems. I have tried many ad blasters, and hardly any did what they promised to do.
Maybe GroupsMailer is different? They write on their site that you can write millions of opt in subscribers daily. You will use their automatic e-mail system and not your own ISP. Your ads will be sent to both Yahoo groups and safelists. eMarketing systems are behind this system as well as a few other marketing systems. I have not heard anything negative about this company, but I have not heard any positive things either 🙂
Even though it´s cheap, I might try the GroupsMailer later on, but not today.
