We offer two options. One, we set up bulk email software and SMTP configuration on your system and you can use it to send bulk email from your location. Two, we handle bulk email using our system, resources and people, freeing you to focus on your business. Then again, we can configure bulk mail software for you to let you use your own ISP services or we can specially set up a separate mail SMTP server that places no limits on the number of emails you can send. We already have our own SMT server and if you choose to let Nimbus handle it for you, you get more at lower costs.
