Which tool should I use?
Three common scenarios. Pick the one that matches what you're trying to do.
Verify ONE address
You're prospecting on LinkedIn and found a contact. Check if the email is real before you bother writing an outreach.
Clean a LIST
You just exported a CSV from Apollo, ZoomInfo, or Hunter. Strip invalid addresses before your campaign goes out.
Automate at SCALE
You need API access, 100,000+ emails per list, or want to integrate validation into your CRM webhook.
