c1.testrun.org provides a low-maintenance, resource efficient and
interoperable e-mail service for everyone. What's behind a chatmail is
effectively a normal e-mail address just like any other but optimized
for the usage in chats, especially DeltaChat.
In the Delta Chat account setup you may tap Create a profile then Use other server and choose Classic e-mail login. Here fill the two fields like this:
E-Mail Address: invent a word with
exactly nine
characters
and append @c1.testrun.org to it.
Existing Password: invent at least nine characters.
If the e-mail address is not yet taken, you'll get that account. The first login sets your password.
Un-encrypted messages are blocked to recipients outside c1.testrun.org but setting up contact via QR invite codes allows your messages to pass freely to any outside recipients.
You may send up to 60 messages per minute.
Messages are unconditionally removed 20 days after arriving on the server.
You can store up to 100M messages on the server.
If you remove a c1.testrun.org profile from within the Delta Chat app, then the according account on the server, along with all associated data, is automatically deleted 90 days afterwards.
If you use multiple devices then you need to remove the according chat profile from each device in order for all account data to be removed on the server side.
If you have any further questions or requests regarding account deletion please send a message from your account to privacy@testrun.org.
This chatmail provider is run by a small voluntary group of devs and sysadmins, who publically develop chatmail provider setups. Chatmail setups aim to be very low-maintenance, resource efficient and interoperable with any other standards-compliant e-mail service.
