Get 50%+ more valid emails out of the lists you already paid for. Listmint verifies standard emails via SMTP and verifies catch-alls in real-time without sending any emails.
Listmint verifies emails in domains that accept everything. Most tools mark these as “risky.” We tell you which ones you can actually use.
Real-Time Results, No Emails Sent
Other email verification tools often take 24 to 48 hours and “verify” by sending messages. Listmint is real-time and never sends emails to the address you are verifying. Your email deliverability will not be taking a hit.
