The best email services to use with NeoMutt on Linux

NeoMutt is one of the most powerful email clients for the terminal. It was born as an evolution of Mutt and is designed for users who want to control their email from the console, with keyboard shortcuts, configuration files, integration with external tools and highly customized workflows.

It is not a client for everyone. NeoMutt has a steeper learning curve than applications such as Thunderbird, Evolution or Geary, but in return it offers a very fast, lightweight and flexible experience. It is especially interesting for users of i3, Sway, Xfce, MATE, GNOME or KDE Plasma, and for distributions such as Arch Linux, Debian, Fedora, Ubuntu, openSUSE, Alpine Linux or Linux Mint.

NeoMutt can work with local mail, Maildir, tools such as mbsync or offlineimap, and also with native IMAP. Its documentation states that it supports mailbox browsing on IMAP servers, which makes it compatible with many modern providers as long as they clearly offer IMAP/SMTP. (neomutt.org)

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

1. Fastmail: the best balance for NeoMutt

Fastmail is probably the provider that best fits NeoMutt if you are looking for a stable, fast and easy-to-maintain experience. It is a paid service, but it is strongly oriented toward users who want to use external clients without depending on a web interface.

Fastmail documents the use of IMAP, POP and SMTP to connect accounts with third-party clients. It also states that IMAP, POP and SMTP connections require their own app password, which is very useful for NeoMutt because it allows you to separate the main password from the client configuration. (fastmail.help)

Advantages of Fastmail in NeoMutt

• Excellent compatibility with IMAP and SMTP.
• Very good performance in external clients.
• Ideal for custom domains.
• Clear configuration for advanced users.
• Very good option for workflows with mbsync, msmtp or Maildir.

Disadvantages

• It does not have a full free plan.
• It is not as focused on end-to-end encryption as Proton Mail.
• It may not interest you if you are only looking for a free account.
• It is more practical than radical in terms of privacy.

Opinion

Fastmail is the best email service for NeoMutt if you want balance. It is not the most private provider in absolute terms, but it is one of the most convenient for working from the terminal. For users of Arch Linux, Debian, Fedora, openSUSE or Alpine Linux, it is a very well-rounded choice.

2. StartMail: privacy with classic IMAP

StartMail is one of the best options for those who want privacy without giving up traditional clients. This makes it very interesting for NeoMutt, because a terminal client benefits from providers with clear IMAP/SMTP and device-specific passwords.

StartMail documents its mail servers with imap.startmail.com on port 993 with SSL/TLS for IMAP, and smtp.startmail.com on port 465 with SSL/TLS for SMTP. It also states that it does not support POP3. (support.startmail.com)

Advantages of StartMail in NeoMutt

• Good privacy approach.
• Compatible with IMAP and SMTP.
• Reasonably direct setup.
• Good alternative to Gmail and Outlook.
• Very good option for technical Linux users.

Disadvantages

• It is a paid service.
• It does not support POP3.
• It may require manual setup.
• It is not as well known as Gmail, Outlook or Proton Mail.

Opinion

StartMail fits very well with NeoMutt because it combines privacy with classic configuration. It does not force you to use its own client or a complex bridge. If you want privacy and terminal use, it is one of the most sensible options.

3. Infomaniak Mail: European provider for domains and serious email

Infomaniak Mail is a very interesting option for NeoMutt if you want a European provider focused on professional email, domains and cloud services. Its greatest advantage for a terminal client is that it works with standard protocols and clear manual configuration.

To use it with NeoMutt, the important thing is that Infomaniak allows email synchronization through IMAP and sending through SMTP. Its documentation indicates settings such as mail.infomaniak.com, port 993 with SSL for IMAP, and SMTP with port 587 and STARTTLS. (infomaniak.com)

Advantages of Infomaniak Mail in NeoMutt

• Good compatibility with IMAP and SMTP.
• European provider.
• Very interesting for custom domains.
• Suitable for freelancers, businesses and personal projects.
• Fits well with manual configurations on Linux.

Disadvantages

• It may require manual setup.
• It is not as popular as Gmail or Outlook.
• Some features are better used from its web ecosystem.
• It may be more interesting for users with a custom domain than for a basic account.

Opinion

Infomaniak Mail is one of the best options for NeoMutt if you are looking for a serious European provider compatible with standards. For users of Debian, Arch Linux, Fedora, Ubuntu or openSUSE, it makes a lot of sense as an alternative to Google and Microsoft.

4. Mailfence: privacy and complete suite

Mailfence is also a good option for NeoMutt if you want privacy and a European provider with more features than a simple inbox. It offers email, calendar, contacts, documents and collaborative tools, although NeoMutt will mainly focus on email.

Mailfence allows SMTP, IMAP and POP to be used on compatible plans such as Entry, Pro and Ultra. For NeoMutt, this is enough: if you have a plan with external-client access, you can configure it like any other IMAP/SMTP account. (kb.mailfence.com)

Advantages of Mailfence in NeoMutt

• Good privacy approach.
• Compatible with IMAP, POP and SMTP on compatible plans.
• European alternative to Gmail and Outlook.
• Good option for users who want more control.
• Interesting if you also use its web features.

Disadvantages

• Access with external clients depends on the subscribed plan.
• NeoMutt does not take advantage of calendar, contacts or documents.
• It may require manual setup.
• It is not as simple as Gmail for beginners.

Opinion

Mailfence is a very solid option for NeoMutt if you are going to use a plan compatible with IMAP/SMTP. You will not take advantage of its whole suite from the terminal, but as a private and standard provider it works very well.

5. Zoho Mail: good option for businesses and domains

Zoho Mail makes a lot of sense with NeoMutt if you want professional email, a custom domain or an alternative to Google Workspace and Microsoft 365. It is especially interesting for freelancers, small businesses and projects that want to use a terminal client without giving up professional features.

Zoho Mail allows IMAP to be used in any compatible standard client, although IMAP access must first be enabled from the account. If two-step verification is used, it may also be necessary to generate an app password. (zoho.com)

Advantages of Zoho Mail in NeoMutt

• Good compatibility with IMAP and SMTP.
• Very useful for custom domains.
• Interesting for small businesses and freelancers.
• Alternative to Google Workspace and Microsoft 365.
• Good balance between price and features.

Disadvantages

• It may require manually enabling IMAP.
• Some features depend on the chosen plan.
• Its ecosystem may be too broad if you only want email.
• It is not as direct as Fastmail for terminal users.

Opinion

Zoho Mail is a good option for NeoMutt if your priority is professional email. It is not the most minimalist provider, but it offers an interesting combination of price, custom domain and business features.

6. Gmail: popular, but not the best for NeoMutt

Gmail can be used with external clients, but it is not the most convenient option for NeoMutt. The problem is not only IMAP or SMTP, but authentication. Gmail usually works better in clients with integrated OAuth2 or more graphical flows, while in NeoMutt it may require more steps, app passwords or additional tools.

Even so, Gmail remains valid if you already depend on Android, Google Drive, Google Calendar or Google Workspace. On distributions such as Ubuntu, Fedora, Debian, Arch Linux or Linux Mint, it can be configured, but it is not the cleanest provider for a purely terminal workflow.

Advantages of Gmail in NeoMutt

• Very popular service.
• Lots of storage.
• Compatible with IMAP and SMTP.
• Ideal if you already use Google services.
• Good option for existing personal accounts.

Disadvantages

• It is not the best option for privacy.
• It may require app passwords or additional settings.
• It depends heavily on the Google ecosystem.
• It does not fit as well with TUI clients as it does with modern graphical clients.
• Some features are better enjoyed from the web.

Opinion

Gmail can work in NeoMutt, but I would not choose it as the first option if you are building your workflow from scratch. For a terminal client, Fastmail, StartMail, Infomaniak or Mailfence make more sense.

7. Outlook / Hotmail: useful if you depend on Microsoft

Outlook and old Hotmail accounts can be used with external clients, but they are not the most natural fit for NeoMutt either. Microsoft has been strengthening modern authentication, and that can complicate use in terminal clients if there is no convenient OAuth2 support.

Outlook makes sense if you already use Microsoft 365, OneDrive, Windows or a corporate account linked to the Microsoft ecosystem. For users who switch between Linux and Windows, it can be practical, but it is not the cleanest option for NeoMutt.

Advantages of Outlook in NeoMutt

• Good option for Microsoft users.
• Free accounts and paid plans.
• Suitable for personal, academic and professional use.
• Clear alternative to Gmail.
• Useful if you switch between Linux and Windows.

Disadvantages

• It may require more adjustments than other providers.
• The full experience is more designed for Outlook web or Microsoft Outlook.
• It does not stand out for privacy.
• It is not the most convenient option for a terminal client.
• It may cause more problems than more direct IMAP providers.

Opinion

Outlook is valid if you already use it, but it would not be a main recommendation for NeoMutt. If you want a clean terminal workflow, it is better to choose a more open provider that is easier to configure manually.

8. Proton Mail: very private, but not very direct in NeoMutt

Proton Mail is one of the best options if absolute privacy is the priority, but it is not the most convenient for NeoMutt. To use Proton Mail with external clients, Proton Mail Bridge is required, which creates a local IMAP/SMTP connection between your Proton account and the email client.

Proton states that Bridge integrates Proton Mail with IMAP/SMTP clients, but official support is more oriented toward Thunderbird, Apple Mail and Outlook. (proton.me) With NeoMutt, it may be possible if configured manually against the local Bridge, but it is not the simplest combination.

Advantages of Proton Mail in NeoMutt

• Very high privacy.
• Strong encryption within the Proton ecosystem.
• Good alternative to Gmail and Outlook.
• Complete ecosystem with email, calendar, VPN, storage and password manager.
• Interesting for advanced users.

Disadvantages

• Requires Proton Mail Bridge.
• Less direct setup.
• Official support is more oriented toward other clients.
• To use Bridge, a paid plan is normally required.
• It is not the best option for a simple TUI workflow.

Opinion

Proton Mail is excellent as a private service, but I would not place it among the best practical options for NeoMutt. If you want privacy with more direct integration, StartMail or Mailfence fit better. Proton makes sense if you are an advanced user and accept configuring Bridge manually.

Final ranking

Rank	Email	Rating
1	Fastmail	The best balance for NeoMutt
2	StartMail	Best private option with IMAP
3	Infomaniak Mail	Best European option for domains
4	Mailfence	Privacy and complete suite
5	Zoho Mail	Very good for businesses
6	Gmail	Popular, but less ideal
7	Outlook	Useful for Microsoft users
8	Proton Mail	Very private, but not very direct

Which one should you choose?

For the best overall experience in NeoMutt, I would choose Fastmail. It is stable, fast, works well with IMAP/SMTP and fits perfectly with a terminal email client.

If privacy is the priority, StartMail is one of the best options because it maintains a relatively simple IMAP/SMTP configuration. Mailfence is also highly recommended if you want privacy and a European provider, although access with external clients depends on the plan.

Infomaniak Mail deserves a special mention because it combines a European provider, standards compatibility and a good fit with custom domains. For Linux users working on Arch Linux, Debian, Fedora, Ubuntu, openSUSE or Alpine Linux, it can be a very attractive alternative.

Gmail and Outlook are valid options if you already use them, but not the most convenient for NeoMutt. They work better in graphical clients with more integrated OAuth2. Zoho Mail stands out if you need professional email, while Proton Mail remains an advanced privacy option, but with less direct integration.

Conclusion

The best email service for NeoMutt depends on the type of user:

• Best overall: Fastmail
• Best private option with IMAP: StartMail
• Best European option for domains: Infomaniak Mail
• Best private option with a complete suite: Mailfence
• Best for businesses: Zoho Mail
• Most popular: Gmail
• Best for Microsoft users: Outlook
• Best advanced privacy: Proton Mail

If you use NeoMutt on Linux, especially in environments such as i3, Sway, Xfce, MATE, GNOME or KDE Plasma, and on distributions such as Arch Linux, Debian, Fedora, Ubuntu, openSUSE, Alpine Linux or Linux Mint, it is best to choose a provider with simple IMAP and SMTP. That is why Fastmail, StartMail, Infomaniak Mail and Mailfence are the options that best fit this terminal email client.
