Translate a post to another language

I need the Spanish version of our April 12 product launch post for our Madrid audience. Keep the tone friendly but professional, preserve the discount code SPRING20, and limit it to 220 characters so it fits the post template. Sign off with "Equipo de Lúmina" and flag any idioms that don't translate cleanly.

Before I post the translated copy to the Madrid page, make it easy for someone in marketing to approve. Put the key offer SPRING20 at the top, show the original English sentence beside the translation for the line that mentions "limited stock," and call out one sentence where a literal translation might sound odd in Spanish.

The translator sent a direct Spanish version that keeps our English idioms. The Madrid community manager is worried it will sound robotic to locals and might lower engagement. I cannot tell if we should soften the tone or keep literal accuracy for legal reasons. Do we prioritize idiomatic flow or exact wording for compliance, and what small edits will satisfy both?

Across multiple markets we keep losing engagement because translations are literal and take extra review cycles. Which habit should our team change first: give translators the target audience notes and examples, or create a short approved glossary of brand phrases? Recommend one concrete process change and how to pilot it in two weeks.
