I like that it's easy to use and also gives me confidence in knowing my business has been verified by more than one source, which helps with customer trust. Also if you're using it for your own personal account, then it's not too difficult to understand how it works either. There are some things about it that could be improved but nothing majorly so. Give it try! The best part of this product is being able to confirm that all of my clients' emails have a real address attached to them without needing to worry myself about checking each individual message.
