Frequently Asked Questions FAQ
Diff Checker vs Word Compare?
Diff Checker compares *lines* and *order* (good for versions). Word Compare compares *sets* of words (good for lists). It tells you what items are present in both lists regardless of position.
Can I compare email lists?
Yes! This is perfect for finding which emails are present in both your 'Subscribers' list and your 'Unsubscribed' list to clean your database.
