missed your email

[goodstudent]

I have many emails everyday and recently I just discovered I missed an email that I should reply. (I was searching for some keywords and that email happen to pop up and I saw it today)

I want to email the person and say something like I have overlooked your email or missed your email to that person who emailed me, and then continue to reply.

How do I say it?

I have many emails every day (two words) and recently (delete this) I've just discovered that I missed an email that I should have replied to. (I was searching for some keywords and that email happened to pop up and I saw it today)

I want to email the person and say something like I have overlooked your email or missed your email to that person who emailed me, and then continue to reply.

How do I say it?

"I'm sorry I didn't reply sooner but I missed your email."
