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 am more looking into BTRF for backup due to I run Linux and not BSD ZFS requires more RAM I only have one disk I want to benefit from snapshots, compression and deduplication.
