Depends on what kind of recovery you're talking about. If it's corrupted then restoring a backed up wallet.dat is your best bet, or -salvagewallet if you don't have a back up.
If you lost the passphrase then you can try to bruteforce it, the chance of success depends on how long and complex your passphrase is.

This is a very interesting topic I too have a similar experience losing a wallet.dat I just don't try to recover it since I only had a few coins on it,what I do is to always create a duplicate in my cloud storage,but I also would like to know how to recover your wallet.dat if you accidentally or not delete it..

To be clear I have a wallet.dat file with a password, that I do in fact remember, on a flash drive. Do I just download a program and copy and paste it?

Yes, if your wallet.dat is from an outdated version then you might need to run core with -upgradewallet option. Keep in mind that you need to sync to see your balance. If you've already downloaded it and have synced then you'll have to run core with -rescan option too.

This page (https://achow101.com/2016/07/Bitcoin-Core-Troubleshooting#option-startup) have instructions on how to run bitcoin core with a command line option.

The wallet.dat must be in the data directory[1] when you start the wallet. It will need some time to sync and verify the currently ~100 GB blockchain. Once thats done you can use the coins. If you moved to a more powerful machine you should set a new password.

Their is two of recovering the wallet , one if you are using blockchain then you have to download the software and copy and paste the old wallet.dat file in the app folder and then you have to run the sofwate and it will sync fully after wards you will be able to see your address and the bitcoin stored in the wallet. this may take time for sync

if you are using electrum or other wallet then it is the same precedure but it will be soon as this wallet dont need lot of data to sync and even through passphrase also you can rebuild your old wallet.

If you lost your wallet.dat and didn't keep a backup in any form then your bitcoins are lost.
Bitcoin core and most desktop wallets doesn't use email btw.  You might be using some other wallet.  If that's the case then create a new thread about it to avoid hijacking this one.
