Thunderbird has SOGo Connector and Integrator extensions. - **Built for large deployments:** The site says SOGo has run in production with thousands of users and focuses on scalability and open standards. - **Paid support tiers:** Yearly Alinto contracts cost 500 to 7,500 euros and add production repositories, incident tickets and response times. ## Good for - Organizations replacing Exchange with a self-hosted groupware server - Admins who need Outlook and phone sync without MAPI connectors - Teams comfortable running their own IMAP and SMTP servers ## Worth knowing - It is software to install: you supply the mail and database servers, and it provides no hosted mailbox. - Production-build package repositories require a paid support contract from Alinto; free users get nightly builds. - Nightly builds are described as untested and not recommended for production use. - Support contracts are priced in euros per year: 500, 1,500, 5,000 or 7,500, per a price list dated September 2024. ## ToolGPA grades **GPA: 2.2 out of 4**, graded Nov 13, 2026. SOGo is open-source groupware with webmail, calendars and contacts that you install on your own server. Production-ready builds sit behind a paid support contract starting at 500 euros a year, and the free nightly builds aren't meant for production. - **Value for money: C.** Free 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: C.** The software is free to download, but the free route is nightly builds that the project calls untested. - **Features: B.** Webmail, calendars, contacts, ActiveSync and Outlook and Thunderbird support, and the listing shows no gap in the groupware job. - **Ease of use: D.** You install it and wire it to your own mail and database servers. - **Platforms and integrations: B.** A web interface, plus ActiveSync, Outlook, Thunderbird and Apple Calendar connections. There's no desktop app of its own. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Alinto's own pages on 13 November 2026. Not based on using the product, and shorter than our full reviews. ## Where it stands among email apps - SOGo's GPA of 2.2 is higher than 29 of the 122 other email apps we grade, and level with 24. - It stands best on features (B, above 79 of 122) and worst on ease of use (D, above 0). - SOGo has no paid plan. - On features, ease of use and platforms it scores 2.3 out of 4. Nothing scores higher for less, though at least one tool matches that score at a lower price. The category's chart of price against score: https://toolgpa.com/charts/email ## Keep it, or make your own? **Keep it.** SOGo is free, so making your own would save you nothing. And it is not the kind of software a weekend replaces. That makes this kind of software worth paying for, not this one in particular: 69 of the 122 other email apps grade higher. - You could make: Calendar: an app builder makes this well. - You could not: An email client: sending, receiving, threading and searching years of mail. - You could not: Sharing with other people, which means accounts and invitations. - You could not: The depth: we grade its features B, which means it covers the whole job.
