Interspire Email Marketer was built from the ground up to help service providers such as web designers, advertising / marketing agencies and ISP's offer a do-it-yourself email marketing solution to their clients. Interspire Email Marketer is a multi-user solution that means you can create a user account for each one of your clients, so they have access to their own "control panel". From inside this control panel, they can create and send email campaigns, view statistics and so forth. You can create an email template for them to use, or they can choose one of the built in email templates.
You can choose to let them create and send their own email campaigns, or you can do it on their behalf.
Every email that gets sent out is sent from the email address and URL that you define, so the recipient sees the email coming from your clients domain and not yours. You can private label
Interspire Email Marketer with your own logo, color scheme etc so your clients see it as your own solution and not ours. There are many other service provider specific features
such as email throttling, user specific timezones and more.
There's also a user guide available to members of the partner program. This is a PDF file and can be obtained through request to the Email Marketer team.
