About this server
Verify email addresses live against their mail server and find work emails. Nothing stored.
Hosted — runs on the provider's infrastructure; connect over HTTP/SSE. Indexed under Productivity, alongside 1214 other servers. Health is freshness-derived from the registry's last-update timestamp; this index does not run the server, so capabilities and tool lists live in the source repository.
