Notification from old emails

[Android Central Question]

On my Samsung S9 I get normal email notifications, but I also get notifications of random older emails that were read and/or deleted weeks ago. How do I stop this?

Welcome to Android Central! Which email app are you using, and what kind of email account is it (IMAP vs POP3)?

Has anyone found a fix for this? I bought a S9 about a month ago and experience the same issue. Random old emails in notifications.
I use the email app that came with the phone (not Google email app) using IMAP

I never had this issue with my old S4. Same email account and settings.

If you look in the email list, are those random old emails marked as unread?
