I have been searching for a killer electronic mail app, and this is likely to be it

I do most of my emailing from my iPhone using Apple Mail. On my MacBook, I use Apple Mail once more, however I’ve all the time struggled to discover a solid email client for Windows. In the event you do most of your emailing on Home windows, you will know the wrestle of looking for a very good electronic mail shopper.

Outlook is bloated (and crammed with adverts in case you’re utilizing it without spending a dime), Microsoft has killed off Home windows Mail, and browser-based shoppers are messy at finest. Thunderbird was my open-source alternative for years, however in 2025, I really feel it seems somewhat dated and packs too many options I’ve by no means wanted to make use of.

What I wished was easy: a clear, fashionable, quick, and free electronic mail shopper for Home windows that does not bury me in muddle or adverts. After spending a while attempting out totally different e-mail shoppers, I’ve lastly discovered my favourite: meet Betterbird.

What’s Betterbird?

An up to date Thunderbird

Betterbird is a fork of Mozilla Thunderbird, constructed by its builders with one purpose: fixing what Thunderbird will get improper. Thunderbird remains to be extensively used and actively maintained, however its legacy design and sluggish replace rollout typically weigh it down. Betterbird, however, takes the identical open-source basis and makes it sharper, sooner, and simpler to make use of.

The mission describes itself as a “higher Thunderbird,” and, after utilizing it for some time, that is exactly what it feels wish to me.

Why Betterbird stands out

No adverts and no pointless options

The place Outlook pushes adverts and additional providers, Betterbird focuses on the necessities. It is a cross-platform electronic mail shopper that runs on Home windows, Linux, and macOS, however it feels particularly refreshing on Home windows, the place first rate free shoppers may be tough to search out.

The very first thing you could discover is Betterbird’s efficiency. It launches shortly, handles a number of inboxes with out lag, and makes navigating between folders and calendars painless. It takes the Thunderbird core and trims among the fats.

Including accounts in Betterbird is quick and simple. From POP to IMAP and Trade, all main providers are supported — in contrast to Outlook, which typically forces you thru a number of complicated re-authentication hoops. In the event you’re coming from Thunderbird, the expertise will really feel acquainted, however the enhancements — like cleaner account administration and fewer bugs — can be instantly noticeable.

Options that matter

No bloat

Whereas Betterbird most likely will not win any design awards for minimalism, the app does handle to strike a stability that Thunderbird by no means absolutely managed. The format is clear, absolutely customizable, and responsive. There’s correct darkish mode help, together with the flexibility to tone down blinding white emails in order that they’re simpler on the eyes.

Themes are additionally supported, so you possibly can tweak the interface to your liking. In the event you’re used to Gmail-style shortcuts, don’t be concerned — you possibly can map them immediately in Betterbird.

With lively updates and neighborhood help

Betterbird does not conceal its performance behind paywalls, nor does it muddle your inbox with adverts. It is absolutely open-source software program, funded by consumer donations, and pushed by the philosophy that electronic mail ought to be a dependable and accessible instrument.

I discover this to be a refreshing distinction to Microsoft Outlook, which feels extra like a funnel into the Microsoft 365 ecosystem, which holds primary multi-account help hostage until you pay to improve. With Betterbird, the whole lot you see is what you get, it packs full performance from the second you employ the installer.

Certainly one of Thunderbird’s greatest criticisms has been the tempo of updates. Butterbird tackles this by releasing fixes and refinements way more shortly. Bug fixes that will take months in Thunderbird are likely to arrive a lot sooner in Betterbird, which, for me, makes it really feel extra polished on a day-to-day foundation.

All of this is not to say that Betterbird is ideal. As a result of it is a fork, it could typically really feel prefer it’s ready for Thunderbird’s subsequent huge transfer earlier than it could adapt. Documentation can also be thinner in comparison with Thunderbird, so you could sometimes must dig via boards for solutions to your issues. And whereas the UI is cleaner than Thunderbird, it isn’t as minimal as fashionable Mac-style electronic mail shoppers. In the event you’re anticipating Apple Mail simplicity, Betterbird nonetheless leans towards Microsoft power-user territory.
