Bulk Email Boxer · Paid tool
Email verification that catches bounces before you send.
Verification combines syntax, DNS, and MX checks with a live provider verdict: valid, invalid, or unknown. Catch-all domains are reported as valid, and unknown results are refunded. One universal credit is one cent; purchased credits never expire.
