Lead Validation checks whether an email address is real and safe to send to. Sending to dead addresses causes bounces, and a high bounce rate damages your sending reputation faster than almost anything else.
Click Lead Validation in the left sidebar. The landing page is a dashboard showing Total Validated Emails, Total Emails Found, your Top Verification Failure, and a list of Recently Verified Emails.
The three tools
Tool | What it does | When to use it |
Email Verifier | Checks one address at a time | Spot-checking a single contact |
Validate Email List | Checks a whole list in bulk | Before adding any imported list to a campaign |
Email Finder | Finds an address from a name and company domain | You know who you want but not their email |
When you need it
Leads enriched through Lead Explorer are already verified, so validation matters most for data you brought in from somewhere else — CSV imports, purchased lists, scraped lists, or anything more than a few months old. Around 2% of B2B addresses go stale every month as people change jobs.
It uses its own credits
Validation runs on email verification credits, which are a separate balance from ST Credits. Running out of one doesn't affect the other. See Verification Credits & Plans.
