April 2026* | Lebensmittelproduktion | Empfehlungsbewertung: 10.0/10 > > **Vorteile**: One of Thunderbird’s biggest strengths is how easy it is to handle several email accounts at once. The integrated calendar, contact management, tags, and filter tools make staying organized effortless, even in a busy workday. It performs reliably, respects user privacy, and allows a wide range of personalization through themes and add-ons, which makes it suitable for both personal and professional communication setups. > > **Nachteile**: The only drawbacks I’ve noticed are that the interface design looks a bit outdated compared to modern email clients, and certain advanced functions require additional add-ons to be installed. Occasionally, updates may change how some extensions work, which can require a bit of time to readjust or reconfigure. Still, these are minor issues compared to the stability and usability Thunderbird offers. > > The calendar integration works smoothly, and features like filters, folders, and tags make daily email management efficient. Thunderbird is lightweight but still powerful enough for professional use. ----- ### "Thunderbird Review" — 5.0/5 > **Leandro** | *2.

Mai 2026* | Gesundheit, Wellness & Fitness | Empfehlungsbewertung: 10.0/10 > > **Vorteile**: My favorite thing about Thunderbird is this it works with Protonmail which is my preferred email service > > **Nachteile**: I guess I would like it to have some a few more options for color themes though it probably does have some and I just didn't know where to look > > Really great\! I also like that it has in the settings some options for extensions that will increase its capabilities ----- ### "Not the best email client" — 3.0/5 > **Ireshyn** | *7. Januar 2025* | Forschung | Empfehlungsbewertung: 5.0/10 > > **Vorteile**: The product is free to use and relatively easy to setup > > **Nachteile**: Many basic features from other email clients are missing and/or hidden. > > I opt to use other email clients over this as it is feature poor. ----- ### "Good email client, but could be improved" — 4.0/5 > **Hugo** | *9. Mai 2025* | E-Learning | Empfehlungsbewertung: 7.0/10 > > **Vorteile**: If the best OSS email clients, it fast and almost without bug > > **Nachteile**: Sometimes buggy, slow to open large email of big conversation with a lot of destinations, and conversation history is not always good (the thread construction I mean, being able to read send email and received in a unified way as in GMail) > > Overall pleased but I'll like to see it improved ----- Seite: 1 / 8\ Weiter: [Nächste Seite](https://www.capterra.com.de/software/1013328/thunderbird?page=2) ## Links - [Auf Capterra anzeigen](https://www.capterra.com.de/software/1013328/thunderbird) ## Diese Seite ist in den folgenden Sprachen verfügbar | Sprache | URL | | de | | | de-AT | | | de-CH | | | en | | | en-AE | | | en-AU | | | en-CA | | | en-GB | | | en-IE | | | en-IL | | | en-IN | | | en-NZ | | | en-SG | | | en-ZA | | | es | | | es-AR | | | es-CL | | | es-CO | | | es-CR | | | es-DO | | | es-EC | | | es-MX | | | es-PA | | | es-PE | | | fr | | | fr-BE | | | fr-CA | | | fr-LU | | | ja | | ----- ## Strukturierte Daten
