We use the service ourselves at Team and a Dream and are extremely satisfied with it. However, I wondered what other companies offered the same service after I heard about the IPO. After talking to some of our clients and browsing through the web, I’ve compiled a list of seven alternatives to Constant Contact (in no particular order).

1. iContact – In addition to creating, sending and tracking e-mail newsletters, you can also create and send surveys, blogs, and RSS feeds. Prices start at $9.95 a month. This service charges you on the number of contacts you have - not the number of e-mails sent or a flat fee basis. They also offer a 20% discount to non-profits.
2. Zookoda – This site is exclusively for bloggers that want to e-mail posts to readers on a periodic basis. They offer template customization and scheduled recurring e-mails. In addition, they also offer deep reporting features to see what’s being read, clicked on, etc. The service is free and the company was recently acquired by PayPerPost.
3. Newsberry – Another e-mail campaign service that allows you to create your e-mail, send it to your list, and track the results. The difference is that they offer a pay as you go model – not a monthly subscription like Constant Contact.
4. ReachMail – The company services small businesses in addition to large enterprises. They also offer XML integration to keep your e-mails frequent and streamlined.
5. ennectMail – Also has a pay as you go model, charging five cents per e-mail. A unique feature I noticed here is what they call “HotPlots.” This shows you who your hottest prospects are, how well your e-mails are working, as well as your contacts participation over time.
6. MailerMailer – Offer a range of packages from free - where you can send 200 e-mail messages a month - to platinum for $349.95, where you can send up to 500,000 e-mails.
7. Emma – This company is praised for their customer service as well as their intuitive features. Their service includes custom designs, which are available for a fee. It is the only site I’ve seen that charges a one-time setup fee of $250.
