Email Blasting for Multiple Clients - Questions

[designergirl]

I own a graphic design studio and I would like to start offering e-mail blasting to my clients. I want to design, blast and maintain their e-mail lists so they don’t have to.

I took a look at a couple of of sites like Constant Contact that offer e-mail blasting services, but I couldn't figure out if I would be able to hold one master account and be able to send e-mails on the behalf of different clients to separate e-mail lists with out having to open an individual account for each client.

Does anyone know of, or if there is a company that offers this type of service?

Or would I have to set up a separate account for each one of my clients and have to login each time under a different user name? Or would my clients have to get the account themselves?

Any recommendations would be greatly appreciated.

Thanks!

At the agency where I work, we use this: Cooler Email.

For each email blast we send out on behalf of our clients, there's a separate log-in.

Most companies I've looked at (I just researched this stuff last week) offer the ability to use multiple lists. Just keep a separate list for each client and you can pick and choose each list based on their needs for that newsletter.

I ended up going with MailChimp. Their tracking services are pretty good and I have to admit, I really like monkeys.
