EmailShield is built into LeadSonar

You don’t have to leave LeadSonar to verify the leads you found there. LeadSonar runs EmailShield for you:

1. In Lead Finder → My Leads, select the leads.
2. Click Enrich selected and tick EmailShield verification.
3. Each lead gets an email status, so you know which ones are safe to send to.

LeadSonar’s own guide walks through it step by step, including what it costs in LeadSonar credits: Verify with EmailShield — LeadSonar Docs.

When to use EmailShield directly

Use the EmailShield app at app.emailshield.co when:

• The list came from somewhere else — another data provider, a CRM export, an event, a scrape.
• The list is large. Upload a CSV or Excel file of any size your plan’s credits cover; see Upload a list.
• You want the full breakdown — every status, catch-all risk scoring and filtered exports, described in Reading your results.
• You’re building it into your own tools with the EmailShield API.

Verify the week you send

A LeadSonar list is fresh when you export it, but people change jobs every month. If a list has sat for a few weeks, run it through EmailShield again before the campaign starts.
