Thanks a lot, the command works great!

Since I wanted to do it through clipboard I did the following:
Set a macro in neomutt:
        macro index,pager B |'xsel --clipboard'

This pastes a message to clipboard with xsel. Then in my git 
repo I run:
        xsel -ob | b4 am -t -o - | git am -s

And since I am using lazygit quite often I set a custom 
command also under "B" to do it quickly:
          - key: "B"
            command: "xsel -ob | b4 am -t -o - | git am -s"
            context: "localBranches"
            loadingText: "B4 with message from clipboard"
            description: "Use message in clipboard with b4 to apply patches from a ML"

Maybe it will be helpful to someone else.
