Established company has new product that appeals to different customer base. We want to send Can-Spam Compliant emails to purchased lists. Need an SMTP server with replaceable IP Address (if needed) or complete software/IP sending solution. Plan under 50,000 emails/month but would like to be flexible to scale upward. Have a group sending email program but could use an online-based HTML sending system instead.
Must track opens and clickthroughs, with opt out function etc.
