Nuestra lista de recomendaciones contiene clientes de correo electrónico que soportan [OpenPGP](encryption.md#openpgp) y una autenticación fuerte como [Open Authorization (OAuth)](https://en.wikipedia.org/wiki/OAuth). OAuth te permite utilizar la [Autenticación Multifactor](basics/multi-factor-authentication.md) y previene el robo de cuentas.
??? advertencia "El correo electrónico no proporciona el secreto de reenvío"
Cuando se utiliza una tecnología de cifrado de extremo a extremo (E2EE, por sus siglas en inglés) como OpenPGP, el correo aún tendrá algunos [metadatos](email.md#email-metadata-overview) que no son encriptados en el encabezado del correo.
OpenPGP tampoco soporta '[forward secrecy](https://en.wikipedia.org/wiki/Forward_secrecy)', lo que significa que si la clave privada del receptor es robada, todos los mensajes encriptados previamente con esta se encontrarán expuestos: [¿Cómo puedo proteger mis claves privadas?](basics/email-security.md) Considere utilizar un medio que brinde 'forward secrecy':
[Comunicación en tiempo real](real-time-communication.md){ .md-button }
**Thunderbird** es un cliente gratuito, de código abierto y multiplataforma, de correo electrónico, grupos de noticias y chat (XMPP, IRC, Twitter), desarrollado por la comunidad Thunderbird, y previamente por la Fundación Mozilla.
We recommend changing some of these settings to make Thunderbird a little more private.
Estas opciones se encuentran en la página de configuración *Privacidad & Seguridad* ( ≡ → Ajustes → Privacidad y Seguridad).
##### Web Content
- [ ] Uncheck **Remember websites and links I've visited**
- [ ] Uncheck **Accept cookies from sites**
##### Telemetry
- [ ] Uncheck **Allow Thunderbird to send technical and interaction data to Mozilla**
#### Thunderbird-user.js (advanced)
[`thunderbird-user.js`](https://github.com/HorlogeSkynet/thunderbird-user.js), is a set of configurations options that aims to disable as many of the web-browsing features within Thunderbird as possible in order to reduce surface area and maintain privacy. Some of the changes are backported from the [Arkenfox project](https://github.com/arkenfox/user.js).
## Platform Specific
### Apple Mail (macOS)
!!! recomendación
{ align=right }
**Apple Mail** is included in macOS and can be extended to have OpenPGP support with [GPG Suite](encryption.md#gpg-suite), which adds the ability to send PGP-encrypted email.
**Evolution** is a personal information management application that provides integrated mail, calendaring and address book functionality. Evolution has extensive [documentation](https://help.gnome.org/users/evolution/stable/) to help you get started.
When replying to someone on a mailing list the "reply" option may also include the mailing list. For more information see [thundernest/k-9 #3738](https://github.com/thundernest/k-9/issues/3738).
**Kontact** is a personal information manager (PIM) application from the [KDE](https://kde.org) project. It provides a mail client, address book, organizer and RSS client.
**NeoMutt** is an open-source command line mail reader (or MUA) for Linux and BSD. It's a fork of [Mutt](https://en.wikipedia.org/wiki/Mutt_(email_client)) with added features.
NeoMutt is a text-based client that has a steep learning curve. It is however, very customizable.
**Please note we are not affiliated with any of the projects we recommend.** In addition to [our standard criteria](about/criteria.md), we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.
!!! example "This section is new"
We are working on establishing defined criteria for every section of our site, and this may be subject to change. If you have any questions about our criteria, please [ask on our forum](https://discuss.privacyguides.net/latest) and don't assume we didn't consider something when making our recommendations if it is not listed here. There are many factors considered and discussed when we recommend a project, and documenting every single one is a work-in-progress.
### Minimum Qualifications
- Apps developed for open-source operating systems must be open-source.
- Must not collect telemetry, or have an easy way to disable all telemetry.
- Must support OpenPGP message encryption.
### Best-Case
Our best-case criteria represents what we would like to see from the perfect project in this category. Our recommendations may not include any or all of this functionality, but those which do may rank higher than others on this page.
- Should be open-source.
- Should be cross-platform.
- Should not collect any telemetry by default.
- Should support OpenPGP natively, i.e. without extensions.
- Should support storing OpenPGP encrypted emails locally.
