As an excellent programmer once noted: constraints induce creativity and focused design. Delta Chat has been running against classic e-mail provider constraints for years and had to evolve its code to work against these constraints (rate limits, spam filters, signups, delays etc) and thus we were uniquely positioned to create a minimal #chatmail server template that beats Gmail, Outlook, iCloud etc regarding security, performance and efficiency. It's a similar story with #deepseek if you will.
