The Spanish phrases, and when each one fits

Spanish is informal ('tú') almost everywhere a card is involved — family, friends, colleagues. 'Usted' is for a client or an elder you address formally; in Latin America it is more common than in Spain.

  • ¡Feliz cumpleaños! — “Happy birthday!”. The standard wish, everywhere Spanish is spoken.
  • ¡Felicidades! — “Congratulations!”. Said on birthdays too — very common on its own.
  • ¡Que cumplas muchos más! — “May you have many more!”. The classic follow-up line.
  • Que tengas un día maravilloso. — “Have a wonderful day.”. When the day itself is the point.
  • Un abrazo enorme en tu día. — “A huge hug on your day.”. Warm — friends and family.
  • ¡A brindar por ti! — “Let's toast to you!”. Playful, for a group card.
