One of the fastest-growing companies in the email verification industry (according to INC. 5000) is ZeroBounce, a US-based email verification service.
With their API integration, you can prevent unwanted sign-ups and have clean email lists. A well-managed API dashboard allows you to look over daily and monthly reports.
They use AI technology to score your catch-all email address, which is risky to send through A.I., providing you with a better idea of whether to send an email to each email address.
While other providers like MyEmailVerifier and Debounce verify 10k emails in less than $30, ZeroBounce charges $60.
You don't have to worry about your data privacy with Zero Bounce. They are Swiss EU-US privacy shield certified vendors. There are only 2-3 vendors with this certification.
Zero Bounce is a qualitative choice if you are looking for extra information about the email validation results and informative analysis.
