Clean CSVs before they hit outbound. LeadTale combines email verification, phone reveal, GPC opt-out detection, and contact-graph writeback so every verification run improves the next one.
The public calculator uses domain distribution only. No SMTP probing, no DNS lookups, and no verification credits are consumed.
Paste 5-10 emails. LeadTale classifies the domains and predicts typical invalid, disposable, catch-all, and role-based exposure without SMTP probing or DNS lookups.

The output separates invalid addresses from catch-all, disposable, role-based, and broader corporate risk so you can choose the right Verify tier before uploading the full list.
Pure-play tools validate what you already have. LeadTale ties verification to compliance signals, integrations, and a living B2B contact graph.
Standard verification checks deliverability signals without charging for enrichment layers you did not ask for.
Run email deliverability checks, phone reveal + verify, WhatsApp confirmation, and carrier checks from the same upload.
Surface valid-but-blocked contacts before they reach outbound tools, lists, or client workspaces.
Matching LeadTale contacts inherit the latest verification result, so every batch improves future lookups.
Pricing is on-success where noted. Failed lookups do not silently consume full-depth credits, and email verification stays at the Standard tier.
SMTP handshake, catch-all flag, GPC opt-out, and SPF/DKIM/DMARC signals.
+0.25 cr per confirmed WhatsApp hit. Invalid/unverifiable numbers are free. List reveal is a separate product at 5 cr.
On-success notation means the surcharge applies only when that layer returns a billable hit.
