How we grade them

|---|---|---|
| Value for money | CFree under LGPL v2.1, but you host it, and that needs a server. Self-hosted free is a C for value. | CFree only if you host it yourself, which needs a mail server and a database. Production builds need a support contract from 500 euros a year. |
| Free plan and trial | BFree outright with no caps. You need to install it yourself, which keeps it at B and not A. | CThe software is free to download, but the free route is nightly builds that the project calls untested. |
| Features | CA combined inbox, several protocols, Sieve filters and search across accounts. It is a client only, so mail still lives with other providers. | BWebmail, calendars, contacts, ActiveSync and Outlook and Thunderbird support, and the listing shows no gap in the groupware job. |
| Ease of use | DNo store rating on record. The site offers an installation guide and a config generator, which means setup is on you. | DYou install it and wire it to your own mail and database servers. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
