Numerous reasons. The main ones being we are now in control of the
message and can assure it is properly DKIM signed with no violations,
and also in control of the sending domain making sure that
DKIM/SPF/DMARC policies are correctly configured to actually send to a
mailinglist. And having both a html and plaintext part consistently
across messages (yes, some systems do actually consider emails without
a html part spam these days -- the opposite of what it used to be).
And longer term we'd expect the fact that people can
subscribe/unsubscribe to individual topics are going to make it more
likely that they don't just hit "this is spam" -- previously you could
subscribe to -announce to get our release announcements but would also
receive a lot of things entirely unrelated to that, with the only
common topic being postgres.
