Do you think we need more specialized email validation services for client data?

I’ve recently built an email validation API that checks for MX records, flags disposable emails, and identifies patterns of invalid emails. It’s designed to help filter out incorrect or temporary addresses to improve data quality. It also works as a standalone service that other platforms can easily integrate. Curious if others have faced challenges with email validation in client data, particularly for maintaining clean, high-quality email lists. Is this something you’d find valuable, or are existing solutions already sufficient?
