What is Matrix and Element

What is Matrix and Element

We use the Matrix messaging system for communication between members – whether they are working on projects, coordinating events, or just staying in touch with the wider community. We also run Digital Privacy Coaching rooms on Matrix, where people can ask questions, share experiences, and get help improving their online privacy.

To make Matrix easy to use, we recommend the Element app as the main way to access it.

This post explains what Matrix and Element are, using familiar tools like email and WhatsApp as comparison points.

Email, Matrix, and the Apps You Use to Access Them

Most of us are used to:

  • Email – via apps like Gmail, Outlook, Hotmail, ProtonMail
  • Chat apps – like WhatsApp, Signal, Telegram, Facebook Messenger

Matrix fits into this landscape as another messaging system, and Element is one of the apps you use to access it.

A useful way to think about it:

  • Email is a messaging system.
  • Gmail, Outlook, ProtonMail are apps that let you use email.
  • Matrix is a messaging system.
  • Gmail, Outlook, ProtonMail are apps that let you use email.

Just as you can choose your email app but still email anyone else, you can choose your Matrix app (we recommend Element) and still talk to people using other Matrix apps.

Email: The Familiar Baseline

Email is one of the oldest internet messaging systems. Nearly everyone has an email address, and we use it for:

  • Sending and receiving messages
  • Attaching files and documents
  • Communicating across different providers (Gmail → Outlook, ProtonMail → Hotmail, etc.)

The key idea:

  • You can choose different email providers and apps.
  • They all still work together because they use a shared standard for email.

That shared standard is what makes email interoperable – it doesn’t matter if you use Gmail and someone else uses Outlook; you can still contact each other.

Matrix: A Modern Messaging Network

Matrix is similar in spirit to email, but designed for modern, real‑time communication.

Matrix supports:

  • One‑to‑one chats
  • Group chats and project rooms
  • Community spaces (like public or semi‑public channels)
  • Sharing photos, videos, and files
  • Voice and video calls (depending on the app)

Where email is primarily designed around an inbox and messages that don’t need instant replies, Matrix is designed for:

  • Real‑time chat
  • Ongoing rooms and channels
  • Rich media sharing

For DFA, Matrix is also attractive because it offers:

  • Strong privacy options
  • End‑to‑end encryption (so that only the participants can read the messages, where enabled)
  • Decentralisation – it’s not owned or controlled by a single company

Element: Our Recommended App for Matrix

If Matrix is the network, Element is the app we recommend you use to access it.

  • Matrix is the underlying system.
  • Element is the client (the program you actually use).

You install Element (on your phone or computer), log in to your DFA account or server, and from there you can:

  • Join DFA project rooms
  • Take part in Digital Privacy Coaching rooms
  • Direct message other members
  • Share files, links, and media
  • Join voice or video calls (where available)

There are other Matrix apps out there, but DFA recommends Element because it is relatively user‑friendly, supports key features well, and has a strong focus on privacy and security.

Side‑by‑Side: Email vs Matrix

Here’s a simple comparison you can drop straight into the blog:

Feature / Idea

Email

Matrix

What it is

One of the oldest internet messaging systems

A modern, open messaging network

Main use

Messages that don’t need instant replies; more “letter‑like”

Real‑time chat, group rooms, communities, calls

How you use it

Through apps like Gmail, Outlook, Hotmail, ProtonMail

Through apps like Element (and other Matrix clients)

Group chats

Possible but clumsy (reply‑all, mailing lists, long threads)

Built‑in rooms and channels designed for group conversation

Real‑time chat

Not really; you check your inbox when you feel like it

Designed for instant messages and ongoing chat

Sharing photos/videos

Attached to emails

Shared inline in the conversation, like chat apps

Voice/video calls

Usually separate tools (Zoom, Teams, etc.)

Many Matrix apps, including Element, support calls directly

Privacy and security

Varies by provider; often processed by big companies

Strong privacy focus; can be end‑to‑end encrypted

Who controls it

Large providers handle and store your email

Open protocol; different organisations (including DFA) can run servers

Side‑by‑Side: WhatsApp vs Matrix (Using Element)

Since many people know WhatsApp, this comparison helps to position Matrix:

Feature / Idea

WhatsApp

Matrix (using Element)

Who controls it

Meta (Facebook)

Open network; no single owner

Account tied to

Your phone number

An account (e.g. @username:server), not locked to a phone number

Which app you can use

Only the official WhatsApp app

Many apps; DFA recommends Element

Works across apps and providers

No – closed ecosystem

Yes – different apps and servers can communicate if they speak Matrix

Group chats and communities

Yes, within WhatsApp

Yes, including rooms and larger community spaces

Encryption

End‑to‑end encryption inside a proprietary system

End‑to‑end encryption using an open standard

Who holds the data

WhatsApp / Meta

The organisation running the Matrix server (e.g. DFA’s chosen provider or its own server)

For DFA, Matrix offers the best of both worlds: the immediacy of a chat app like WhatsApp, but with the openness and interoperability of something more like email.

How DFA Uses Matrix and Element

Within DFA, Matrix and Element are used for:

  • Project collaboration
    Each project can have its own room(s) where members coordinate work, share files, and discuss tasks.
  • General DFA community rooms
    Spaces to connect with other members, share news, and discuss topics related to digital freedom.
  • Digital Privacy Coaching rooms
    Dedicated rooms where people can:
  • Ask privacy‑related questions
  • Request help configuring devices or apps
  • Share resources and guides
  • Learn from others’ experiences

Element gives members a single app they can install on their phone or computer to access all of this.

Summary

  • DFA uses Matrix as its messaging network.
  • Element is the app we recommend to access Matrix.
  • Matrix is:
  • Like email in that it is open and interoperable.
  • Like WhatsApp in that it supports real‑time chat, rooms, and media sharing.
  • This combination aligns with DFA’s values around digital freedom, privacy, and user control.
