Deliverable. Safe to send and keep in your campaigns.
Will bounce. Removed to protect your sender reputation.
Catch-all domain, flagged so you can segment and send with care.
Mailbox providers judge you on bounce rate. Send to dead addresses and your inbox placement drops for your whole audience, not just the bad ones. A single clean before a big send is the cheapest deliverability insurance there is.

Everything about cleaning your email list.
An email list cleaning service removes the addresses on your list that would bounce or harm your sender reputation: invalid and non-existent mailboxes, duplicates, spam traps, disposable addresses and role accounts. Email Verifier API cleans your list with a 16-point engine, including a live SMTP check, and hands back a deduplicated, safe-to-send file in minutes.
Upload your list as a CSV or Excel file (or send it through the API). Every address is checked for syntax, domain and MX records, mailbox existence via a live SMTP handshake, plus catch-all, disposable, spam-trap and role detection. You then download the results grouped into Passed, Failed and Unknown, ready to import back into your email platform.
It is pay-as-you-go: one credit per address, and you only pay for definitive Passed and Failed results. Credits never expire and there is no subscription, so a quarterly clean never wastes what you bought. Every new account starts with 100 free credits, so you can clean a sample at no cost. Estimate your price with the cost calculator.
Invalid and misspelled addresses, dead mailboxes, duplicate entries, disposable and throwaway domains, known spam traps, and role accounts like info@ and sales@. Catch-all domains are flagged as "unknown" so you can decide how to handle them, rather than being wrongly marked valid.
Yes. We operate a zero-storage policy: the addresses you submit are SHA-512 hashed and automatically deleted within 30 days, and verification never sends a message to your contacts. The process is non-intrusive and GDPR-friendly.
Email data decays by roughly a fifth or more every year as people change jobs and abandon inboxes. A full clean each quarter, plus real-time verification on new signups, keeps bounce rates low and your sender reputation healthy between cleans.
