It is a lot more robust than other free software > > **Cons**: Some of the styling is a little bit lacking but I need to be fair and say I've not tried to look for settings to change it so maybe it's better to say default styling is poor. > > I was using another free email client that would not let me use different ports for incoming and outgoing mail so when searching for another one thunderbird looked great and has been very good so far. ----- ### "Thunderbird Review" — 5.0/5 > **Leandro** | *2 December 2025* | Computer Software | Recommendation rating: 10.0/10 > > **Pros**: It offers great security , access and conectivity . Fast , light weight email client .Also is open source and doesn't spam you > > **Cons**: The Ui it's a little outdated . Sometimes it is difficult to find the way to access some of its features. > > I use it as my main email client , both for personal use and for work , it feels comfortable .Big plus that they don't spam you ----- ### "Solid email service especially to integrate with Protonmail Bridge" — 5.0/5 > **Jeffrey** | *2 May 2026* | Health, Wellness & Fitness | Recommendation rating: 10.0/10 > > **Pros**: My favorite thing about Thunderbird is this it works with Protonmail which is my preferred email service > > **Cons**: 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 January 2025* | Research | Recommendation rating: 5.0/10 > > **Pros**: The product is free to use and relatively easy to setup > > **Cons**: 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. ----- ### "Reliable, Well-Organized, and Easy to Use Email Client" — 5.0/5 > **Sven** | *1 April 2026* | Food Production | Recommendation rating: 10.0/10 > > **Pros**: 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. > > **Cons**: 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. ----- Page: 1 / 8\ Next: [Next page](https://www.capterra.co.uk/software/1013328/thunderbird?page=2) ## Links - [View on Capterra](https://www.capterra.co.uk/software/1013328/thunderbird) ## This page is available in the following languages | Locale | 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 | | ----- ## Structured Data
