Project mention: Outlook is Microsoft's new data collection service | news.ycombinator.com | 2024-01-11
I confirm the issue of delays/freezing of Claws-mail. I really liked the simple UI, but freezing too often, couldn't stand it. I had searched about it, I got some answers that's it's single threaded if I recall well.
Since you mentioned mutt and it's steep learning curve, I recommend you another TUI MTA/mail app. It's nmail (https://github.com/d99kris/nmail). Simple, Pine/Alpine like interface, has great features (for example, saving mails in sqlite - can be used offline). Also the developer is active and friendly, in case you find bugs or have any proposals for enhancements.

EMailSender
Arduino, esp32, Esp8266 EMailSender with Arduino IDE, simple library to send email via smtp with attachments.
-
pboted
Standalone C++ client for I2P/Bote (server-less encrypted KademliaDHT-based email protocol). (by PurpleBote)
There is another Bote implementation named pboted, but a planned feature is "Sending email anonymously" so it does not do that at the moment? If someone would be able to clarify this, it would be greatly appreciated

WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
