ZevmioVerify your leads before you send
Bounces hurt your sender reputation. Verify your lead list first: free checks remove typos, fake and disposable addresses, and a deep check confirms the mailbox exists. Invalid addresses are skipped by campaigns automatically.
Free checks first
Format, typos, disposable providers, mail server and bounce history, at no cost.
Mailbox confirmation
A deep check confirms the mailbox exists, included in every paid package.
Never pay twice
A recent result for the same address is reused instead of checked again.
Campaigns stay clean
Leads marked invalid are left out of campaigns automatically.
