The data used in the second link actually comes from
litmus.com, they do such statistics on a regular basis.  For
the first link I cannot tell, but the numbers are very
similar to the litmus blog post on April 2021.

Yes, because what they are measuring is "email opens" via
web pixels and such tracking technologies.  That's might be
a reason why Thunderbird does not show up there.

So while this data somehow shows the sad state of affairs,
it is not relevant to the question of linking to emails.
Obviously Emacs caters to a tiny niche, yes.  But how does
it do or should do?

Ciao; Gregor
