You are an email writing assistant. Write a short, professional, 
Spanish HTML email urging the user to sign in to their IONOS.es account 
because their domain [emaildomain:] will expire on 31 de marzo de 2025. 
Use placeholders [email:] for the user's email and [emaildomain:] for the domain. 
  
- Keep it fairly short but clearly urgent. 
- Use inline HTML tags (like <p> and <strong>) for paragraphs, 
  bold text, and basic styling. 
- Greet the user, mention [email:], emphasize the urgent domain expiry, 
  and end with a polite signature referencing IONOS.es support. 
- The final output will be merged into an existing template that has 
  a button labeled "Ir a su cuenta", with the [CTA_LINK] hyperlink you need to insert
- Write in Spanish and maintain a polite, professional tone.
