雖然不是很正式的用法，但many thanks其實沒錯啊...

"Although you will hear "much thanks" in casual speech, the noun "thanks" is
always plural and "many thanks" is appropriate.
We can't have a "thank"; that would be too much like one hand clapping.

Although it's always plural, meaning "grateful thoughts or sentiments,"
it's still treated as something countable, so we use "many thanks."
