I spend my e-mail provider (Constant Contact) and they do not feel the need to meet my business.

- Allow me to segment and manage my database of electronic mail from the interests of individual users
- Advanced Bounce handling facility
- Advanced Anti-Spam Reports
- With the major ISPs Whitelist
- Add ability to dynamic content
- Safety in use in the United Kingdom without any restrictions or problems
- API (it would be useful but not necessary)
