I am new to this forum but thought would be the best place to ask a couple of questions. I am working with a friend of mine who has a very large (legitimately owned and opt-in collected) email database. The problem is, these are in CSV file format having transferred out of another system - somewhere in the region of about 10 million. We need to be able to set these up in a new mailing system - and not one which charges $200K per month - even if they approve the import. Various systems are happy with the import but charges are crazy. So we are looking for a self served solution.. This database will be used for it's primary marketing purpose - i.e. in terms of initial email offer sent to them. After that, we would like to be able to email these addresses with similar material. (We are aware of can-spam rules). Someone has suggested that we find someone who can provide self hosted software with a mailer/uploader that can be used to send emails in batches of 20K with an IP rotator. Does this make sense to anyone? Can anyone else advise? Does anyone know if this sounds right or is there another option? I would be really grateful for any advice. Cheers
