Hello AngieC1969,
To help us get a better understanding of the issue, we’d like to ask a few questions.
1. Are you using the Apple Mail app with that account, or are you using another app?
2. It seems like certain emails are missing, correct? If so, are the missing emails from certain contacts or senders only?
The above details will help us plan how to proceed.
If you are using the Mail app, please also check out this link, which will guide you through how to check if the emails were deleted, and if so, how to recover them: Delete and recover emails in Mail on iPad

Thanks!
