Base tech resilience comes from tools that can be used offline. #deltachat apps are offline-first in that you can create chats, send messages, look at messages/media and trigger establishung contact via qr code scans. And you can use #webxdc apps (with checklist, calendars, editors, shopping lists etc) because they not only don't require Internet but are barred from accessing it, providing privacy that doesn't require #gdpr or consent or login.
#deltachat has reliable and audited end-to-end encryption but reliable message delivery is equally crucial in times of shutdowns and increasing Internet fragmentation. #chatmail relays are more reliable and faster than classic email servers but they may still fail, leaving users stranded. The recent rollout of V2 releases not only hardened end-to-end encryption but aims for chat profiles to use multiple relays in the future, removing a common point of failure in decentralized private messaging.
Have been playing with and looking closely at #deltachat for the past couple of weeks. Very impressive.
I set my own #chatmailrelay here for those who want to give it a try: danneskjold.de
@alxlg #WhatsApp is way more popular than #Telegram and they have #e2ee, so that is a huge empty claim, and about your other post, with my post I didn't imply that Telegram is the reason people don't use #DeltaChat etc. I just pointed to the irony of the post.
I agree it is hard to reach the masses without compromises, but let's be honest, if #Meta would put DeltaChat or #xmpp into people like they did with WA, people would use it all the same, it doesn't really matter much
@IkkleGemzUniverse if you have #DeltaChat you can participate anonymously in the #PixelSocial network:
also check https://deltachat-bot.github.io/public-bots for a list of public bots you can try out
@cavyherd that is why #DeltaChat is a better alternative, it requires literally nothing, just set a name and avatar and start chatting, also it has multi-profile support so I have 1 profile for family and friends and another for work and more public interactions,
also the multi-device support is great and I can use different devices for the same accounts, if one device dies I don't lose any message or chat

I've browsed through 9 pages of users comments to an article about #chatcontrol and not a single person mentioned #deltachat. We need to do something about this!
It's going well at Whatsapp it seems:

While classic cleartext email providers, also Thunderbird with its Thundermail efforts, are aiming to be a more trustworthy alternative to Gmail/calendar/drive etc ...
#deltachat and #chatmail efforts go all-in on end-to-end encryption and metadata minimization, with decentralized transport relays playing much lesser roles than #Signal's Amazon/Microsoft/Google servers. At the same time, #webxdc apps provide unprecedented extensibility, eg checkout the great TOTP app https://webxdc.org/apps/#rtn-totp
@matiu_bidule Googles planned restrictions on users abilities to install software is horrible. But it doesn't have much to do with the #deltachat app distribution, as the gmbh is already registered across many stores. We would like to see non-android/non-apple mobile efforts to florish. But let's not mix it too much with the issue of #chatcontrol even if it's true that enforcing chatcontrol would likely imply enforcing app distribution via google/apple eventually, and canceling e2ee apps.
While #chatcontrol poses an existential threat to the Freiburg merlinux GmbH and distributing #deltachat apps from within the EU to all stores worldwide, it would resist any chatcontrol legislation up to the German constitutional and EuGH courts.
If the EU based company would need to fold in a few years, there would likely be forks distributed outside the EU that will *seamlessly* continue to function. Our architecture and FOSS licensing makes sure of it. See also https://chaos.social/@delta/113417740762852318
@energisch_ @kami_kadse @Reinald @dadamsda Falls die Chatkontrolle nicht doch noch verhindert werdne kann, würde mich brennend interessieren, wie es dann mit Delta.Chat Entwicklung aus Deutschland, standardmäßig E2E-verschlüsselt, mehrfach auditiert, basiert auf E-Mail-Infrastruktur, super-einfach (!) zu nutzen. Bietet neben "normalem" Chat auch zB gemeinsam nutzbare Kalender (bestimmt nützlich für Familien), Umfragen, ToDo-/Einkaufslisten, kollaborative Dokumentenbearbeitung, Spiele, uvm.
(siehe angehefteter Toot in meinem Profil)
@ivantodorov yeah, #DeltaChat is more user-friendly, but it doesn't have ringing calls (yet!) but we are working on them right now!
@ivantodorov while there is an ongoing effort to dockerize #chatmail relays, a proxmox version of https://github.com/chatmail/relay/ would be very useful as well. Those relay nodes operate as a cheap chat-optimized federated email server, usable by any #deltachat app
I approve of the decision to stop treating unencrypted emails like chats in the Delta Chat interface. But I note that in emails, the 3 dots menu still says "Archive Chat". More consistent for it to say "Archive Email"?

It seems there might indeed be a spontaneous talk tonight at 7pm at #datenspuren about #deltachat and #chatmail ... In the big room https://talks.datenspuren.de/ds25/talk/BRKQKM/
@walsonde #DeltaChat specially the client I made for it #ArcaneChat :3 https://arcanechat.me
What if a state tries to mandate us as #deltachat app devs/distributors to shut down a chat profile?
Nothing. It can't be done.
We have no list of chat identities, have no handle or data about them, and don't mediate the message transfer.
However, EU #Chatcontrol politicians and Russian authorities would want us to insert backdoors into our FOSS code. But that is nothing than can happen overnight, and we are fine with friendly forks already. Resilient private internet communication ftw :)
Delta Chat is hard to classify when your question is violently binary.
Federated or P2P?
#deltachat is more P2P than #Briar in that we implement a P2P group model while Briar routes everything through a central administrator who owns the group.
E2EE Messenger or e-mail?
#chatmail relays are aiming to be like Signal servers in many ways, but are based on IETF standards around TLS, OpenPGP, MIME, SMTP etc., stripping them all down to the core that we actually need. Quite fun :)
@avoca @mcc i didnt mean for it to be, but #session relies on a #cryptocurrency for the network to function so it shouldnt be on the list anyway, its just a way to start thinking about the different categories of encrypted messengers, #deltachat and #simplex would either be categorised alongside federation or be in a category halfway between federation and peer to peer, #cwtch and #meshtastic would go in the p2p section
@nominom wieso? Funzt einfach!
Siehe @thunderbird / #Thubderbird & @delta / #DeltaChat!
Woah! Only now did we discover a great blog post from @wq who discusses the progression from hosting a #Matrix , a #Snikket and a #SimpleX server, to now running a #chatmail relay https://runtimeterror.dev/self-hosted-chatmail-relay-for-delta-chat/
It's an excellent read, with lots of good advise, including having a public "hello" profile and another unpublished chat profile for private chatting. #deltachat apps have pervasive multi-profile support (and multi-device support) so it's pretty easy to establish such a two-profile setup.
#deltachat is being used in virtually all world regions where one or more other messengers fail to work. We recently released a major milestone (V2 security hardening releases) that prepared the ground for chat profiles to have multiple #chatmail relays at once ... failure or blocking of a single relay would not disrupt chatting anymore. But multi transport also helps with the "centralization problem in decentralized systems" ... https://delta.chat/en/2025-06-04-surge-donations#funding-for-a-globally-scaled-chatmail-relay-network
(Funding is looking good currently btw!)
@Linux nice to see #DeltaChat there 😍
Sometimes we are surprised ourselves how well everything works :)
- cross-platform #deltachat releases every 2-3 months, with a focus on never breaking the world despite significant underlying changes
- many #chatmail relays humming along, including the default onboarding one serving 230K monthly users with ~0 admin hours needed
-lively and sometimes controversial discussions among the diverse dozen core contributors, with an evolving shared vision, both short and long term
Toi Toi Toi
@ben @delta yeah, dumber is smarter here :) and even more powerful:
in contrast to #signal, #whatsapp, the second device in #deltachat is competely independent and self-sufficient. the original device is no longer needed afterwards
@kris you might tap into this video resource https://www.youtube.com/watch?v=gT38FfOXv1E for someone discussing #deltachat in russian -- as far as we know delta chat remains pretty usable in russia despite some attempts to block (and a court case) against us.
@travisfw cleartext email is supported but not recommended and not a #deltachat priority. If your main interest wrt delta is cleartext email it may be better to checkout other mail apps, or to try to motivate would-be-contributors to work on a classic unencrypted-focused "deltamail" fork. You can criticize this stance but its not very ambiguous.
@lavergnetho sounds like #DeltaChat would fit well with your situation, what you get:
warrantied end to end encryption for all your (group) chats
nice multi-device support, no need for a main device, chat from any device, if a device dies you can continue from another without losing a single message
easy migration from one device to another even across platforms
super easy onboarding, good multi-profile support
in-chat widgets and tools that work totally p2p without any 3rd party

#Whatsapp on #iOS had a severe 0day that was exploited in the wild for some months, and is fixed with august 20th releases https://hackread.com/whatsapp-0-day-exploit-attack-targeted-ios-macos-users/
Last year #signal also had its multi-device functionality exploited in the wild. https://thehackernews.com/2025/02/hackers-exploit-signals-linked-devices.html
FWIW #deltachat has a dumber multi-device sync model, no device linking, depends on being in the same WiFI for setup (therefore no easy remote exploits), and #OpenPGP signatures and verification for ongoing usage (like all other E2EE messages).
@lavergnetho did you consider #deltachat?
While most of the feedback on the #deltachat V2 releases has been positive, some users sense a de-prioritization of "classic unencrypted email" usage.
Indeed the current dozen or so contributors aim to evolve an exceptionally resilient and versatile private messenger app suite, with end-to-end encryption the primary focus and design foundation.
However, we would support friendly forkers to develop a classic e-mail focused app suite -- say "deltamail" (work title).

@hiker @delta #deltachat ist für kleine oder mittlere Gruppen, deren Mitglieder einander vertrauen gedacht. Familie, Freunde, Vereine, Aktivitäten usw.
Öffentliche Gruppen wie "DC Community" gehen darüber hinaus und sind als Experiment zu verstehen, mehr sozial als technisch. Zudem war die Super-Gruppe nie offizieller Kanal, sondern "3rd party" - wie einiges anderes, in dezentralen Systemen :) wir wissen nicht alles und wollen das auch gar nicht :)
En cuanto a #DeltaChat @Ganekogorta es buena opción, pero el usar servidores de correo (es muy importante saber cuáles usar) es susceptible a la filtración de metadatos y carecer de una opción nativa para llamadas y videollamadas no la hacen tan atractiva para el común de los mortales que están acostumbrados a dichas opciones en aplicaciones como WhatsApp, Telegram o Signal.
Creo que cada persona debe conocer su nivel de riesgo y así mismo elegir la aplicación de MI que mejor le sirva.

As far as we know #deltachat supports the widest range of old mobile devices. And it's real often hard work to achieve that. For example, on android three (!) rust/networking experts needed to huddle for many days to sort out "how to get own device IP addresses". They ended up implementing several mechanisns suitable for respective android versions. It became part of the @n0iroh network rust stack that powers Delta's integrated peer-to-peer #webxdc realtime networking.
@mhdelpino solo tienes que enviarle /stop y ya 😁
truco para el futuro: por lo general si le envías /help a los bots de #DeltaChat te van a mandar un mensaje de ayuda con los comandos que soporta dicho bot
en el caso de PixelSocial tengo que mejorarlo para que junto con la app ponga un texto explicando que puedes mandar /stop para dejar de usar el bot
What are the main obstacles for you to adopt usage of #deltachat apps with your families, friends or communities?
if you have other issues than the poll options please add to the replies. Oh, and those who are also living through heat waves: stay hydrated, and remind everyone else :)

@methuselah in #xmpp the groups are centralized, server dies, group dies, Conversations is super nerdy, not really on the mainstream level in UI/UX, and in iOS the situation is WAY WORSE with #Monal, in #Conversations groups are rarely encrypted and you get a pretty on your face encryption selector to disable encryption or choose encryption flavor, this is REALLY BAD
I will not even talk about the multi-device support and possibility to easily move your profile between OSs like on #DeltaChat
@blake at first you might not be able to select with which address you write, but having a main address for sending, but in the near future #DeltaChat will get "Multi-Transport" support meaning basically what you want: several inboxes in a single chat list, so you dream might become true in a way, the idea is to have more resilience in case one of the addresses/server goes down, you can keep chatting with the other accounts
We do not aim for #deltachat to be another social media app. No #ai summaries or suggestions. No public directory of contacts. No discovery via outside identifiers (mobile phone or email). Just you and your contacts privately messaging, in a solid simple user interface on all platforms. End-to-End encryption enforced on two layers. #chatmail relays know and retain nothing, no content or metadata. #webxdc apps allow for custom interactions on top of chats.

Tant és quin dispositiu utilitzi, tots ells estan sincronitzats amb tots els contactes i grups del meu compte a #DeltaChat i, a més, fan de còpia de seguretat automatitzada però sense enviar res al núvol de cap empresa. Que tens un problema en un dels dispositius sincronitzats? des de qualsevol dels altres afegeixes un segon dispositiu i fet.

Signal and Matrix were founded in popular opposition to the email system but End-to-End encrypted instant messaging via emails works now, and reliably, with #deltachat V2 app releases, and with #chatmail relays forming a growing secure email network that minimizes metadata and enforces TLS and E2EE messaging.
You can't really argue with working code, can you?
Contrary to popular belief SMTP and DKIM and IMAP are no holy ingredients and can be improved upon btw. See eg https://github.com/chatmail/relay/issues/487

@romadiz algunas ventajas:
- una misma app con la misma calidad/experiencia en múltiples plataformas
- mayor seguridad: no es posible desactivar el cifrado accidentalmente
- los grupos están cifrados
- los grupos son descentralizados, en #XMPP dependen del servidor donde se crea, si este muere, muere el grupo
- #DeltaChat es más #offlinefirst, puedes incluso crear grupos mientras estás offline
por supuesto también xmpp tiene sus ventajas como llamadas que hacen timbrar el celular,etc
Anyone using the ArcaneChat Android app for Delta Chat?
I downloaded it from F-Droid some time ago but looked on Google Play today and realised that the version numbers are completely different, even though both have been updated fairly regularly.
Anyone know why? I haven't yet contacted the developer to ask, but might do so out of curiosity.
Several people noticed and wonder about our new #deltachat version numbering scheme: it changed for all apps! #chatmail Core rust library uses 2.X with incrementing X. And apps use 2.X.Y with Y being a numbered release for a core version. Therefore, any app release embeds the core library version which is helpful for understanding and debugging interoperability issues between clients. Others pointed out this is close to "pride versioning" ... We are fine with that :) https://pridever.org/
V2 #deltachat is rolling out after weeks of internal testing, a major milestone revising how end-to-end encryption works and bringing more beautiful contact and group profiles, direct access to chat-shared apps in the title bar and a "new email" action with setting a subject for those using a classic server.
Best of all, users and developers don't need to co-ordinate anything for upgrading to V2 despite the massive security rework behind the scenes :)
