I use whoismywhoiseveryday to make sure my customers have good customer service from start-to-finish! If they need me there's no question in their mind that they'll get someone back right away if it matters for them.
It would be great to see more robust features such as email verification when registering domains with this api! This is one tool we can't live without anymore since our own internal system has become outdated and unreliable over time. We've been able to resolve issues faster by using these APIs compared to other systems out there which didn't offer any benefit at all.
