My client uses MailChimp to send out mail to approximately 15,000 recipients.
They now want to send out an email from a 3rd party and they don't want it to look like it comes from them - instead from the 3rd party.
We thought about changing the mailchimp configuration, but that might not hide my client properly.
We thought about creating a new mailchimp account for the 3rd party and paying $200 or so. Not sure if that would work well, and if mailchimp would get upset because in theory we are sending one email to people who never subscribed.
Does someone have a relatively safe suggestion? We can pay $100 to $200 for the solution to send mail to under 20,000 recipients.
