| Type of email server |
Pros |
Cons |
| Major ESP server |
Reliable uptime, a guaranteed level of security, no technical knowledge required, and zero management or maintenance required from users |
Lower level of privacy and lack of actual ownership of your email data |
| Private email server |
Highest degree of control and complete data ownership |
Highest level of responsibility, substantial technical knowledge required, constant maintenance and management required, and substantial hardware and software requirements |
| Rented server from hosting provider |
More control than with an ESP and zero hardware requirements |
A high level of maintenance required, less stable and reliable than major ESPs, dealing with a 3rd party, and migration to another provider is often difficult |
