In my example, I am worried that by using the incorrect tense I will imply to the recipient that I did not appreciate the work they put into their letter to me. Specifically, I wrote to a colleague asking a few questions. She wrote back an incredibly in-depth email, telling me everything I could have ever hoped for and more! (In a positive way) If I write: Merci beaucoup pour votre réponse, c'est même plus que j'aurai jamais souhaité! Does this meaning correctly imply that I am delighted with the depth of her email? Or is there a chance it will seem to hide a passive aggressive note that her email was way too long? Thank you in advance for your thoughts!
