The tool works best for machine generated emails where the structure remains the same from one email to the other.

That being said, the parsing engine is quite resistant to noise. For instance, you can have changes in the footer or some other sections of the email, or have additional forwards and it will be able to get the data without issues.

Regarding cleaning up the type of data itself, we don't do any post processing at the moment besides trimming spaces and removing html tags. We plan to add data types at some point (for instance to convert any text date into a standard date) but we'll be waiting to have a paying customer request for it before it gets implemented :-)
