I want to reply to an email that I should have answered two weeks ago already. How can I say the following in an idiomatic manner?
'sorry for the delayed answer'
The email's tone is rather colloquial.
Edit:
What I was thinking of:
'Je suis désolé pour la réponse tardive'
'Je suis désolé que je réponds tardive'
Since I don't have any intuition for the French language I'm absolutely not sure whether this is what one would say.
