Spanish Traduction Plugin

Dear Sir/Madam,
Mailify.com, a client of us, has offered itself to translate the plugin into the spanish version as they believe it will help some of their spanish clients. By the way, they were wondering if it could be possible to have a link back to their site as a recognition for the translation.
I kindly wait for your response.

Best,
