Here are my dotfiles for you to have a look and get an idea: https://codeberg.org/n0p1lls/Config/src/branch/main/dotfiles
There you can see how to configure the mutt client, adjusting it to you through some small changes.
For example, instead of: “set record=“imaps://imap.gmail.com/[Gmail]/Enviados” for your gmail account, if your language is English, it would be something like this: “set record=“imaps://imap.gmail.com/[Gmail]/Sent".

If you want to configure the keybindings, see this section: https://neomutt.org/guide/configuration#6- changing-the-default-key-bindings
The app is very nice.
