The problem ist not the "error?", but the "error:"
Send will, when it does not fail, return "null" and this causes the "needs
a value" problem when trying to set the word "error:". The sollution:
if error? set/any 'error: try [....]
set/any allowes to set null to values, too.
An other sollution would be:
if error? error: try [.... none]
Your example looks not like it will send the email. Because you are
producing a function and check it, if it is an error. This is not true,
because function! <> error! . So you will not run the if-body
