A little more simplification is possible:

`,(string-append title ...) --> (string-append  ...)

The code `,A after macro-expansion simply becomes A, for every A.
To test, you can run
  ,expand `,(string-append title " something")
in a Guile REPL.

Also,
             '("Guix Data Service")))
seems incorrect.  The end result if title is #f would be
  (title ("Guix Data Service")),
while I believe you wanted
  (title "Guix Data Service").

Correct code would be

>      (title ,(if title
>             `,(string-append title " - Guix Data Service")
>             "Guix Data Service"))
or alternatively

or

I don't know how familiar you are with quasiquote (`), quote (') and
unquote (,); it may be worthwhile to look this up in the Guile maual

          `,(string-append title " - Guix Data Service")

I recommend sending e-mails as plain text.  One benefit is that plain
text doesn't mess up code indentation (at least on e-mail clients using
fixed-width fonts for plain text, which seems standard).

Greetings,
