Questions about ZeroBounce.
The practical details behind the request, access and result.
How does the ZeroBounce MCP help my email deliverability?

Yes, it provides an AI score from 0 to 100 for your leads. This helps you see which contacts are more likely to be high-value targets for your sales team.
