Thanks for this. Could you post your messages using a channel that
doesn't arbitrarily split your paragraphs into long-short-long-short
lines? It makes paragraphs burdensome to read, and I skipped most of the
message because of that.

I encourage anyone whose messages are munged like that to seek
correction from their mail service provider, and switch to a different
one until it's fixed.
