I think you can simplify it further to
print ${(j., .):-DNS:${^list}}
right?

See also the bash-style ${array/#/prefix} (well you'd also need
a [@] in bash):
print -r -- ${(j[, ]list/#/DNS:}
(also remember "print" like "echo" doesn't do what you want by
default, you need -r with print and -E with echo, misdesigns
inherited from ksh/PWB. And -- or - to mark the end of options).

You almost had it:
% print ${(j., .)${:-DNS:${^list}}}

Hello.
Is it possible to prefix and join an array:
% list=(a.tld b.tld c.tld)
% tmp=(DNS:${^list})
% print ${(j., .)tmp}
DNS:a.tld, DNS:b.tld, DNS:c.tld
but directly, without tmp, something like:
% print ${(j., .)(DNS:${^list})}
