The best email services to use with Betterbird

Betterbird is one of the best alternatives for those who want a powerful desktop email client, very similar to Thunderbird, but with its own improvements and additional fixes. Since it is based on Thunderbird, it works especially well with providers that offer IMAP, SMTP, OAuth2 or integration through tools such as Bridge.

If you use Betterbird on Linux, it fits very well into desktops such as GNOME, KDE Plasma or Xfce, and can be a great option on distributions such as Ubuntu, Debian, Fedora, Arch Linux or Linux Mint. It is a client designed for those who prefer to manage their email from the desktop, with multiple accounts, filters, extensions and unified inboxes.

In this comparison we are going to look at some of the best email services to use with Betterbird: StartMail, Mailfence, Fastmail, Proton Mail, Gmail, Outlook and Zoho Mail.

1. StartMail: privacy with good compatibility for Betterbird

StartMail is one of the best options to use with Betterbird if you are looking for privacy, but without giving up classic integration with email clients. Unlike other private services that heavily limit the use of external applications, StartMail allows you to work through IMAP and SMTP, which fits very well with desktop clients.

This makes it a very interesting option for users of Ubuntu, Debian, Fedora or Linux Mint who want to use Betterbird as their main client without depending on Gmail or Outlook.

Advantages of StartMail in Betterbird

• Good privacy approach.
• Compatible with IMAP and SMTP.
• Very good option for those who want to avoid large platforms.
• Suitable for use in desktop clients.
• Allows a more classic and controlled email experience.

Disadvantages

• It is a paid service.
• It may require manual setup.
• It is not as well known as Gmail, Outlook or Proton Mail.
• It is not the cheapest option if you are only looking for a basic account.

Opinion

StartMail is a very solid option for Betterbird. I would not automatically rank it as the best for everyone, but I would place it as one of the first candidates if you are looking for privacy and real compatibility with desktop clients.

2. Mailfence: privacy, productivity and good support for external clients

Mailfence is another highly recommended provider to use with Betterbird. Its great advantage is that it is not limited only to email: it also offers calendar, contacts, documents and productivity tools, which can be very useful if you want a more complete alternative to Gmail or Microsoft.

On desktops such as KDE Plasma, GNOME or Xfce, Betterbird can become the email management center, while Mailfence adds an extra layer of privacy and collaborative features.

Advantages of Mailfence in Betterbird

• Compatible with IMAP, POP and SMTP on compatible plans.
• Good privacy approach.
• Includes email, calendar, contacts and documents.
• Good European alternative to Gmail.
• Interesting for users who want more than just an inbox.

Disadvantages

• Full access through external clients may depend on the chosen plan.
• It may require manual setup.
• It is not as simple as Gmail for beginners.
• Its greatest value is found in paid plans.

Opinion

Mailfence fits very well with Betterbird if you are looking for privacy, full email and extra features. It is an especially interesting option for those who want to leave Google or Microsoft without losing productivity tools.

3. Fastmail: the best balance for professional use

Fastmail is probably one of the best email services to use with Betterbird if what you want is stability, speed and compatibility. It is a provider strongly focused on quality email, with excellent support for external clients and a very clean experience.

For users of Arch Linux, Fedora, Debian, Ubuntu or Linux Mint, Fastmail is an especially convenient option if Betterbird is going to be the main email client.

Advantages of Fastmail in Betterbird

• Excellent compatibility with IMAP and SMTP.
• Very good stability in desktop clients.
• Ideal for custom domains.
• Fast service focused on email.
• Very good option for advanced and professional users.

Disadvantages

• It does not have a full free plan.
• It is not as focused on end-to-end encryption as Proton Mail or Tuta Mail.
• It may be less attractive for those who only want a free account.

Opinion

Fastmail is one of the best overall options for Betterbird. If you are looking for reliable, fast email designed to work well outside the browser, it is possibly the most balanced option.

4. Proton Mail: advanced privacy, but with Bridge

Proton Mail is one of the best-known options for those looking for privacy. However, to use it with Betterbird, you need to keep an important difference in mind: it does not work like a normal IMAP account, but through Proton Mail Bridge.

This does not make it worse, but it does make it less direct than options such as StartMail, Mailfence or Fastmail. For advanced Linux users, especially on distributions such as Fedora, Arch Linux or Debian, it can be a very powerful solution.

Advantages of Proton Mail in Betterbird

• Very high privacy.
• Strong encryption within the Proton ecosystem.
• Compatible through Proton Mail Bridge.
• Good option for those who want to leave Gmail or Outlook.
• Complete ecosystem with email, calendar, VPN, storage and password manager.

Disadvantages

• Requires Proton Mail Bridge.
• Setup is less direct than with classic IMAP.
• To use Bridge, a paid plan is normally required.
• It may be too much for someone who only wants simple email.

Opinion

Proton Mail is excellent if privacy is the absolute priority. For Betterbird, it is not the most convenient, but it is one of the most powerful if you accept using Bridge.

5. Gmail: the easiest to configure

Gmail remains one of the most convenient options to use with Betterbird. Since it shares its base with Thunderbird, Betterbird usually works very well with Google accounts, especially thanks to OAuth2.

It is a very practical option in any desktop environment, whether GNOME, KDE Plasma, Cinnamon or Xfce, and on practically any Linux distro: Ubuntu, Debian, Fedora, Arch Linux or Linux Mint.

Advantages of Gmail in Betterbird

• Very simple setup.
• Excellent compatibility with IMAP and SMTP.
• Sign-in through OAuth2.
• Lots of storage.
• Ideal if you already use Android, Google Drive, Google Calendar or Google Workspace.

Disadvantages

• It is not the best option for privacy.
• It depends heavily on the Google ecosystem.
• Some Gmail-specific features do not transfer the same way to a desktop client.
• It is not the best alternative for those seeking independence from Big Tech.

Opinion

Gmail is the easiest email service to use with Betterbird. It is not the most private or the most independent, but it is one of the most convenient for users who want to set up the account and start working.

6. Outlook / Hotmail: the most convenient alternative to Gmail

Outlook and Hotmail accounts work very well with Betterbird, especially if you already use Windows, OneDrive, Microsoft 365 or a Microsoft account as your main email.

For those who switch between Linux and Windows, or use Betterbird on Ubuntu, Fedora or Linux Mint, Outlook can be a very practical option.

Advantages of Outlook in Betterbird

• Good general compatibility.
• Very useful for Microsoft users.
• Suitable for personal and professional use.
• Solid alternative to Gmail.
• It has free accounts and paid options.

Disadvantages

• It may require reviewing authentication on old accounts.
• The full experience is still more integrated into Outlook web or Microsoft 365.
• Decent privacy, but not comparable to Proton Mail, StartMail or Mailfence.

Opinion

Outlook is a very balanced option for Betterbird. It does not stand out especially for privacy, but it does for ease, availability and compatibility.

7. Zoho Mail: good option for businesses and custom domains

Zoho Mail is a very interesting alternative for those who want to use Betterbird with a custom domain or professional account. It is especially useful for freelancers, small businesses or users who want to separate their personal email from their professional email.

On desktops such as GNOME, KDE Plasma or Xfce, Zoho Mail can work very well with Betterbird as the main client, especially if you work on distributions such as Debian, Ubuntu, Fedora or Arch Linux.

Advantages of Zoho Mail in Betterbird

• Good compatibility with IMAP and SMTP.
• Interesting for businesses, freelancers and custom domains.
• Competitive alternative compared with other premium services.
• Good productivity ecosystem.
• Can be configured in desktop clients.

Disadvantages

• It may require manually enabling IMAP.
• Some features depend on the subscribed plan.
• Its ecosystem may feel too broad if you only want email.
• It is not as simple as Gmail for home users.

Opinion

Zoho Mail is a good option for Betterbird if the goal is professional email or a custom domain. It would not be my first choice for a basic user, but it is a very competitive alternative for small businesses and freelancers.
