Can we use muchas gracias for goodbye mail

What a great question!

While "muchas gracias" is a wonderful phrase to express gratitude, it's not typically used as a goodbye phrase in Spanish. Here's why:

• "Muchas gracias" is a phrase used to express thanks or appreciation, usually in response to someone doing something nice for you or to acknowledge a gift.
• "Adiós" or "hasta luego" are more common ways to say goodbye in Spanish.

That being said, if you want to add a touch of warmth and appreciation to your goodbye message, you could use a phrase like:

• "Muchas gracias por todo" (Thank you for everything)
• "Gracias por todo, adiós" (Thanks for everything, goodbye)
• "Hasta luego, gracias" (See you later, thanks)

These phrases convey a sense of appreciation and gratitude while still being a suitable way to bid farewell.

So, while "muchas gracias" isn't a traditional goodbye phrase, you can still use it in a goodbye message to add a personal touch and show your appreciation for the person or people you're saying goodbye to.
