That's because you want to evaluate (format "%s" i) when the `loop' is executed,
but you have put it inside '(...). So your iterator puts this into
`global-mode-string' at each iteration:
(:eval (mail-bug-mode-line-all (format "%s" i)))
What you really want is this (or equivalent):
(loop for i from 1 to 3 do
(add-to-list
'global-mode-string
`(:eval (mail-bug-mode-line-all ,(format "%s" i)))))
