I often find that I want to email around a doc I’ve put together with sphinx (I often use the *diag or graphviz extensions). Sadly, the world hasn’t embraced the obvious way of supporting this via ePub  readers everwhere. What I want is plain html output, with nothing fancy. There’s probably a style out there, but I just add the following target to the Makefile generated by sphinx-quickstart:
mailhtml: $(SPHINXBUILD) -b singlehtml -D html_theme=epub $(ALLSPHINXOPTS) $(BUILDDIR)/singlehtml @echo @echo "Build finished. The HTML page is in $(BUILDDIR)/singlehtml."
