Email gateway required.

Hello, We are looking for a email marketer/ company who can help us send emails. We are primarily looking only to hire someone as a gateway/smtp and not to use their software(s). What we have: We have a dedicated interspire setup on our server that we use for many users. We host all the data/list on our interspire only. What we need: We need your service for sending emails as an SMTP/PMTA provider We need to track open, bounce (soft and hard) and click through rates We will use our domain name, from email id, bounce id etc (we are open to discuss this) We would be looking for someone who can provide multiple SMTP setups with rotating IPs etc to ensure high inbox rate. This service will be used by us as well as by our clients. Get in touch asap as its needed to start immediately. Thanks!
