In MailChimp v3.3 (launching October 13) you can add this merge tag to your MailChimp campaigns:

*|TRANSLATE:XX|*

(where the “XX” is your language)

and we’ll insert links so that your subscribers can view translated versions of your email.

For example, if you send a MailChimp campaign in Spanish, and then insert this tag in your side column:

*|TRANSLATE:ES|*

MailChimp will insert a column of links to different Google-translated versions of your campaign archive (click to zoom in on the example to the right).

Veldig kul!
