I can in Thunderbird but I don’t reply to companies. They have no reply email adress. Like here is your order number or there is our latest campaign. I use customer chat for help or company have internal message system like banks. In general I like to avoid using email due to the protocol design.
I love when things are in ram. Can have whole vm disks. I also like creating new VMs in ram disks like /dev/shm it makes less wear on my ssd.
