How to recover my notes on my iPhone 4

I accidentally deleted my email off my phone that was hooked up to my notes app & when I went into the app itself all my recent notes were gone. I tried hooking back up my email & they are still missing. My iphone is up to date with the latest IOS & I can't reset my iphone with backup because my iCould storage is less than my iphone & it hasn't backed up in a few months.

If you have not backed up your notes. I think the deleted note are still stored in iphone database. The only way to retrieve them with the 3rd party iphone recovery software from iphone database. Such as http://datarecoveryforiphone.com/ios-data-recovery.html. Hope it can help you.

If it works, can you give me the best answer?
