I use a soap bag. Place a bar of soap in the bag. Soap lathers well through the loose weave. Sisal or cotton fibers exfoliate your skin as you scrub. Then hang it by the drawstring to dry after each use.
I have been using mine for several years. I do not know the brand, but these look similar: soap saver bag from Golden Forrest and sisal soap bag from Olivaris Organics.
I use Tuta mail. It is entirely open source. There are both paid and free tiers. I started on a paid tier, then downgraded to free. I like the option of a usable free tier when money is tight. I use addy.io for aliases.
