@fabi1cazenave I would also like that if you block a person in #DeltaChat, their messages simply don't get displayed in groups you share with them, but to be honest unlike in other apps you mention, in Delta Chat there is no public groups, all groups are private and ideally with close people you know IRL, but in practice me and others use it to have Semi-Public groups and there ignoring some stranger to avoid getting dragged into discussions makes sense
@fabi1cazenave #deltachat supports
1) muting a chat (but not a contact)
2) blocking a contact (which also prevents it from creating a group)
so it may not satisfy your need right now. Many people mute all group chats, and only allow 1:1 chats to cause notifications. Muting individual users might be discussed at https://support.delta.chat if you are interested.
I’m looking for a team chat solution that allows me to *really* mute/block users, like here on Mastodon or with an `/ignore` on IRC.
Zulip and Discord don’t really mute/block messages, they only conceal their content and let you know they’re here. This doesn’t help much imho.
Is this kind of `/ignore` feature available in #Matrix or #DeltaChat?
Otherwise, are there Zulip/Discord clients that support it?
@kyonshi people using classic email servers will be able to write to you, but if you really want to properly be reached in #DeltaChat with encryption which is required for people using public open-registration/anonymous #chatmail servers, you need to share your Delta Chat invite link or QR code, not only #email address
Ya veras que risas usar wasap sin saber catalán.
Pero el botón me sigue ahí.
Ojala poder prescindir. De momento a fomentar y difundir mucho #xmpp y #deltachat
@nthcdr #DeltaChat mode for #emacs, when? 🙏
@sl there is no evidence simplex is particularly resilient .. eg it's been effectively blocked in Russia even if you host inside the country. Matrix impls have dependencies on element servers (newvector) with widgets for example and even if you host a home server inside a country. With telegram and signal people use proxies ... #deltachat has first class support for managing proxies (shadowsocks/ss also used by telegram so one can use the same place proxies with delta)
We'd like to remind everyone that a self-hosted #chatmail relay is best shared in some wider than family circles. In crisis situations everbody does better when helping others.
A typical 1gb RAM chatmail relay VPS for 5-10 eur per month supports 50k+ daily users.
chatmail VPSes are stateless. You can wipe all disk state, reinstall and chatting will resume. Conversely, #deltachat does not keep or depend on any server state .Operators under pressure do not need to feel bad to hand over data.
Lo que más echo de menos de telegram en #deltachat es la posibilidad de poder enviar mensajes sin sonido. Por lo demás, para mí es un reemplazo más que suficiente.
@flan solo tienes que pedir a soporte que lo cambien para poder usar delta.chat

Lo que no se es si vale escribirles en castellano. En xmpp hay un canal en castellano y portugués disroot.es@chat.disroot.org
@andytseng.bsky.social take a look at #DeltaChat
@miriamkl signal is also centralized, and just as with WhatsApp that didn't have that AI for years, it could come to Signal in the future, better to go for decentralized alternatives like #deltachat
@pbg take a look at #DeltaChat it is decentralized, anonymous, doesn't require phone numbers, is offline-first, has in-chat mini-apps and collaborative tools, and it is much more easier to use than SimpleX etc.

Switch to Delta Chat, visit https://get.delta.chat in 5 min your chats will be freed.
Some people in #Iran successfully use delta with national email providers when outside Internet is cut.
#deltachat designs are #OfflineFirst using delay tolerant protocols. Messages are queued when a path is blocked. email servers are made for this and run at planetary scale.
Messages crossing the border may arrive three days later but they arrive.
Peoples can stay in private touch across time and space, to the extent possible in current breakdown times. Which is what delta is about.
We don't see, or plan, a place for AI in our software stacks. A few notes.
Some attempts to use AI tooling provided nothing of value in the chatmail-core-UI stacks that produce the #deltachat store releases on all platforms.
Some in the community AI-generated a base #webxdc app and fixed bugs afterwards.That kind of worked and was borderline useful.
AI is pretty boring. We have more interesting work to do: evolve private resilient messaging by improving UX, networking, encryption, etc
This week in #FDroid (TWIF) is live:
* #ArcaneChat #DeltaChat get a surge of users
* #PeerTube crowdfunds more features
* Swiss #Woz covers #FOSS (they even have a repo!)
* #AuroraStore improvements
- 2 removed apps
+ 4 new apps
+ 161 updates
And some background on the current default:
The default of adding a new line came to be, because we were focusing on email at the time and there you can not delete an accidentally sent email.
Now we focus more on #chatmail and on there everyone uses #deltachat and you can delete and edit messages that were already sent.
Most other messengers use "Enter to send".
Should we change the default keyboard shortcut for sending messages in #deltachat_desktop #deltachat
The question is about whether the `"Enter"` key should create a newline or send the message.
The other shortcuts will stay the same:
- Ctrl/Cmd + Enter is always send
- Shift + Enter is always newline
| Keep: Enter creates newline: | 23 |
| Change: Enter sends message: | 12 |

boostedWe are basically doing what #signal and in particular moxie refused to do or declares impossible: federation.
Both #email and #activitypub ecosystems are all about federation.
However, #deltachat is vertically centralized in that all UIs use the same #rust core which implements all networking, encryption, chat/group/message logic in a single centralized place. The now 40+ #chatmail mail relay network is driven from centralized code.
At each level replication and federation is built in.
Ahora que algunos gobiernos se están planteando migrar a Software Libre. Estaría maravillosamente estupendo incentivar que, tanto servicios públicos como privados, abran sus comunicaciones y soportes de mensajería más allá de Wassap. Cualquiera me sirve: Signal, XMPP, Element, Session o Delta Chat.
#signal #xmpp #deltachat
Everyone returns to email in the end. We are there already. #whatsapp wants you to add your email to secure your account ... despite all the nay sayers and numerous well funded attempts and claims to kill #email not even WA can do it. #deltachat #chatmail and #webxdc are about deep collab between people, projects and operators to evolve email from within. It is not just about SMTP and IMAP and MIME and OpenPGP which are all exchangeable and can be improved ... Which we set out to do. Cheers.

Whatsapp message suggesting to add your email address for extra security
Avec l’histoire de la pub dans whatsapp est-ce qu’on peut directement passer à delta chat sans passer par la case "rachat de Signal par une enflure fasciste" ? Plz ? 
Si voleu tenir, o provar, un perfil de #DeltaChat, feu-vos un compte a
hostatjat per un servidor.
No es demana *res* per a tenir un compte a DeltaChat, podeu ser tan anònims com vulgueu, ni nom, ni correu, ni telèfon.
RES.
Missatges xifrats del vostre dispositiu al destinatari, sense cap opció a que al servidor s'hi tingui accés.
Hi sou benvinguts i benvingudes.
You may setup "burner" phones for specific activities which may face repression including device seizure and forced unlocking. #deltachat does not require a sim card/number and works #OfflineFirst. Seek out wifi or mobile hotspots to connect. At best form or join affinity groups and pre-establish ephemeral chats so everyone can help each other stay safe. Group onboarding is trivial with delta. Note: Digital tools are only ever supplementary to the security coming from caring for each other.
@artfulrobot goodbye fellow 0.001% the other 99.999% of users have #Gmail, and other classic, ehem, "standard" providers that have crazy sending rate limits unusable for chatting and make it EXTREMELY hard to configure with 3rd party clients, since #chatmail and the new onboarding screen was introduced, A LOT more people was able to actually use #DeltaChat
I am also part of the 0.001% and I think it is ok if it is a bit harder for us but easier for the non-technical masses
#deltachat is secure against server-side group membership changes but for a very different reason than #signal which keeps encrypted group membership data in a central store.
Delta Chat has _no_ central store but implements a rigidly tested #p2p group membership model where servers play no role https://github.com/chatmail/models/tree/main/group-membership
Both signal and delta chat are safe against recently published attacks against #whatsapp that can add members to chats, breaking end to end encryption. https://arstechnica.com/security/2025/05/whatsapp-provides-no-cryptographic-management-for-group-messages
#whatsapp claims end to end security of content but:
- ties your identity to a phone number
- owns your identity
- can see who messages whom and who is in which group etc
- forces you to send local search in your private chats to Meta AI
- does not allow to disable Meta AI on the main screen
None of these problems exist with #deltachat devs and distributors. We have arguably the world's easiest onboarding process for a messenger that offers a Whatsapp style interface on all platforms.

@delta I love #DeltaChat... I collaborate with a small chatmail in delta.cuates.xyz
@delta
Ich freue mich, dass #Deltachat immer mehr Nutzer gewinnt 😀
@ex_06 For now, #deltachat will stay focused on private messaging and rather serves as a decentralized alternative to Signal and WhatsApp although the latter is turning into a social media / AI app which we are not aiming to imitate.
> but there are plenty of apps focused on "encrypted chatting
and even many more for unencrypted chatting and unencrypted email
> This feels a bit like #deltachat is abandoning the thing that made it unique!
and highly unused unlike many of the alternatives, since finding a good email provider for chatting is almost impossible even the PAID email providers have strong limits ex. #Posteo only allows 1000 emails per day (and they count per recipient in the To field)

Since June 1st there is a big sudden surge of new Delta Chat users and so far things are going pretty smooth. We are happy that our #chatmail infrastructure is holding up and that there is growing recognition that #deltachat is a ready-to-use and resilient chat solution. Some stats from the last days, a brief discussion of centralization risks and what we plan to do about it, also introducing a brand-new chatmail OpenCollective with a european fiscal host.
More chats, more carbon, less privacy 💬 Your #Whatsapp message might be costing more than you think.💡Time for a smarter switch: #decentralised, private, and low-impact ➡️ Enter #DeltaChat, the alternative instant messenger 👇
Comparing #XMPP against #email protocols is too limited. What sets #deltachat apart is *vertical integration* and being driven by UI/UX considerations. Cross-platform Apps and Bots use the Rust core library which connects with #chatmail relays and classic email servers based on a higher level API -- abstracting over SMTP, MIME, #OpenPGP etc. See https://chatmail.at
#webxdc apps in turn use an even higher level stable API abstracting over email/xmpp/... see https://webxdc.org/docs/
Hi @delta 👋
I am making updates to https://delightful.coding.social/delightful_activitypub_development and bumped into this interesting #SMTP to #ActivityPub proof of concept. Just a heads-up to make you aware, in case it is interesting for #DeltaChat in some way or other.
our friends over at @rpgp just published a monster milestone, humbly tagged 0.16 😍 with
- streaming decryption and encryption
- post-quantum-cryptography
- API streamlining.
#rPGP is a full Rust implementation of #openpgp which counts among the fastest and most compliant implementations today, and includes security audits. Note: #deltachat uses a restricted subset of OpenPGP, and follows best practices (eg using the same ed25519 keys implementation as #signal) https://github.com/rpgp/rpgp/
Mensajería instantánea
De una conversación tecnológica:¿Da WhatsApp (WA) información a la policía?
El entendimiento general es que WA no da contenido de comunicaciones a la policía.
Da metadatos de comunicaciones a la policía, y los metadatos que da son sustanciales, ya que cosas como el nombre del grupo, descripción e icono son considerados «metadatos» por WA (no por Signal), e incluso contenidos de su agenda (y las agendas de sus contactos) se consideran metadatos.
Les defensoras de Signal señalarán que Signal no considera «metadatos» cosas como el nombre de grupo, la descripción o el contenido de la agenda.
La gente acostumbrada a servicios decentes como los de riseup, autistici/inventati, nadir, sinodminio, disroot o aktivix, siempre preferirán protocolos descentralizados donde cualquiera puede configurar su propio servidor federado, como delta.chat o xmpp; son los mejores.
Idealmente hospedados por colectivos decentes.

@tanja yes, there is a pre-discussed concept for sealed sender maybe along with sealed recipients while we are at it. Base idea is to use fixed-format alias chatmail addresses for recipients and allow unauthenticated sending from noreply@chatmailserver to such fixed-format alias addresses (which #deltachat devices learn about through chatting).
La idea de pasarse a XMPP ya como que me remata, porque todo el trabajo de pasar a tu entorno recae en el que lidera la propuesta y para eso hay que tener entusiasmo y fuerza.
Tuve una época en la que estuve usando #deltachat con el correo electrónico y si hay que hacer esfuerzos en promocionar sistemas (en mi opinión) es en el correo electrónico. Mecanismo que empezamos a perder porque todo el mundo tiene uno, todo el mundo lo necesita, pero nadie quiere pelear por el suyo. Igual que con el fediverso.
@rohden Heh, you caught it :) Indeed bots running some LLM for audio transcription or image generation exist. But they are not part of the UI/UX of #deltachat itself, or of its #chatmail core Rust library. Bots and #webxdc apps are behind extension points where we intentionally don't control or even know what people use.
@sommelier @kuulman from the core teams there are no plans to go for ntfy any time soon. #deltachat on #FDroid doesn't use any push notifications and generally works fine in background, and is the best option privacy wise. See e.g. https://mastodon.social/@ati1/114578258005467162
If you haven't seen it, we detail the current state of privacy of google/apple push notifications here https://delta.chat/en/help#privacy-notifications
By design, end-to-end-encrypting #deltachat and #webxdc apps only need ephemeral transport. It's a big deal. Let's compare:
- #matrix home servers maintain a cryptographic forever-chain of cleartext social-graph metadata.
- #WhatsApp servers maintain cleartext metadata visible to Meta.
- #Signal keeps encrypted metadata, hosted at GAFAM
#chatmail relays do not persist any social graph state, also not in encrypted form. A key goal of our designs: chatmail operators can sleep well at night :)
@bjoern @chfkch @delta well it shows that the #deltachat core library can run inside of a home assistant add-on. the same core library is also used for writing bots.
So should be possible, but I don't know #HomeAssistant development enough to say for sure. Like can I expose actions from an add-on, that you can trigger from the home assistant UI, or would I need to extend home assistant itself for that?
The last two days saw the number of push notifications spike. Sometimes 80K Google Play push notifications happened per hour, while the baseline was more around 10-20K. These spikes probably indicate Internet availability. #deltachat is offline-first: you can write messages and attach media, create groups, use #webxdc apps, setup a second device etc. all without any Internet. Once it returns queued messages are sent out and cause push notifications. #OfflineFirst is crucial for resiliency.

a graph showing "Direct push notifications for the last hour"
On the X axis it starts around May 24th 7:30pm and goes until May 26th 7:30pm.
On the X axis it goes from 0 to 80K notifications for the last hour.
There are two plot lines:
- Apple push notifications which are in the range of 7K and 15K notifications in every hour.
- Google Play notifications which is between 10k and 80k notifications per hour. There are around 5 spikes that go up to 70k or above 80k notifications in every hour.

boosted#deltachat Desktop can now run on #Firefox and Safari, entirely avoiding #Electron and Chromium! It's an intended side-effect of the "porting Desktop to #Tauri" effort led by @treefit which aims to provide a non-Electron packaged version of the Desktop. Here is a video and deep dive into what's working on regular browsers now, and what's missing for a full Web version: https://delta.chat/en/2025-05-22-browser-edition
For those wondering about Microsoft Recall because of #Signal's blog post about an option to block screenshots on Windows: #deltachat Desktop on Windows and MacOS have an option to disable screenshots in "Advanced" settings since beginning 2025. It's not enabled by default because we first need to work hard on drafting a big blog post about it .... just kidding :) We'll see if we change the default. We certainly agree that Microsoft needs to change their AI-grabbing and privacy violations.
1 cent per five years .... is the current marginal hosting cost for a #chatmail address, with which #deltachat apps facilitate world-wide private messaging including interactive #webxdc apps that run end-to-end encrypted in any chat group.
<1 Million EUR per year is the estimated marginal hosting costs for 350 Million EU citizens. Such scaling requires, however, research and development, including careful UX and #cryptography work. Related writing from @gordon

screenshot of key excerpt from the referenced post:
"When the network is built on cryptographic protocols, we don’t have to trust anything in-between. We don’t have to trust the computers, the wires, the institutions, beliefs, or kinship of the network participants. We can trust the math. All we have to do is verify the message with cryptography.
This is a powerful primitive for scaling trust, because it means everyone on the network can cooperate together, even if they don’t trust each-other. The costs to producing high-trust results are greatly reduced, and we can spend our coordination efforts on building larger, more fine-grained, more complex networks of cooperation."
Public service announcement:
1. If you want to link your #Fediverse profile to a chat account please consider just saying "DM me for #deltachat invite link" and NOT PUBLISH it to "all".
2. If you do publish invite links to groups and so on, please consider doing it with a dedicated delta chat profile that is not your private profile. Multi-Profile for the win.
3. We want to evolve the #securejoin invite link UX to better prevent unsafe practises. Involves tons of considerations. 💜
With our #deltachat #chatmail and #webxdc efforts we put all intelligence on the end devices, and architecutally separate it from a transport layer that routes safely and fast but knows nothing.
There are a dozen or more #chatmail servers across many jurisdictions, all safely interopable with each other and classic servers.
Turned out we can dumb down email servers by relying on cryptography instead of IP reputation and ai/spam filtering. And have 200ms delivery times. We are not done :)
Did you know that #deltachat does not need and does not use key servers? Most other messengers (wa/signal/matrix/threema/...) actually operate or incorporate a cryptographic key server, managing the cryptographic identities of all users. Delta Chat uses decentralized protocols for key management avoiding a central storage of identities. The SecureJoin protocol is the key (sic!) innovation and was independently analyzed by ETH Zürich researchers earlier this year .... https://delta.chat/en/2024-03-25-crypto-analysis-securejoin
How many people do you know that have lost their messaging history on Whatsapp or Signal, photos etc during mobile phone transitions or breakage or through other shenenigans?
With #deltachat you can:
- export "everything" to a file and import it on any of the many different devices
- or just setup a second device through a QR code scan -- which was happily discovered here after an accidental factory reset https://libranet.de/display/0b6b25a8-2066-0695-ca24-081964494389
