Lead Titan AI verifies every email for your order instead of exporting stored records. Each address gets a mailbox-level deliverability check; only deliverable emails are delivered, while catch-all, unknown, risky and invalid addresses are discarded and generic role inboxes (info@, sales@) are rejected. Because every contact is checked, results arrive over minutes to hours, and credits for leads we can't deliver are refunded automatically.

How It Works

How Lead Titan Verifies B2B Emails

Every email is checked for your order. Only deliverable addresses reach your list — and you only pay for leads we deliver.

Why Email Verification Matters

Email addresses go stale fast. People change jobs, companies rebrand, and mailboxes get shut down. ZeroBounce's 2025 Email List Decay Report found at least 23% of email addresses go bad each year. A contact record that was correct when it was stored can be undeliverable by the time you send to it.

Sending to bad addresses has a real cost. Bounces signal to mailbox providers that a list isn't clean, which hurts sender reputation and pushes even good emails toward spam. Google's email sender guidelines ask bulk senders to keep their spam rate below 0.10% and never reach 0.30%, and to remove invalid addresses from their lists.

What this means for outbound

  • Stored records age: at least 23% of email addresses go bad each year (ZeroBounce, 2025)
  • Bad addresses cost you: bounces hurt sender reputation and inbox placement
  • Lead Titan: every email is checked for your order, and only deliverable addresses are delivered

How Lead Titan Verifies Each Email

Lead Titan doesn't pull a contact from a static export and hand it over. When you place an order, a search runs as a background job, and each lead streams into the app only after it passes verification.

1

Leads Are Found for Your Order

Lead Titan searches business listings and maps, company websites and team pages, public registries and records, plus its own lead bank, for leads that match your order.

  • Strongest for local and small businesses; B2B people search is supported
  • Each candidate lead goes through verification before it can be delivered
Runs as a background job Built for your order, not exported from a stored list
2

Mailbox-Level Deliverability Check

Every email address gets a mailbox-level deliverability check for your order. The check looks at whether the specific mailbox can receive mail — not just whether the address looks right.

  • Checked when you order, not when a record was first stored
  • Each address comes back as deliverable, or as catch-all, unknown, risky or invalid
Checked for every email in your order Confirms the mailbox can receive mail
3

Only Deliverable Emails Are Kept

Lead Titan delivers only emails that come back deliverable (“valid”). Everything else is discarded rather than tagged and passed along.

  • Catch-all, unknown, risky and invalid addresses are discarded
  • Generic role inboxes (info@, sales@) are rejected
  • Fewer bounces, because unverifiable addresses never reach your list
Applied to every lead Removes addresses that can't be confirmed
4

You Pay Only for Delivered Leads

Credits are reserved when you order. Leads that can't be delivered — including ones whose email didn't pass — are refunded automatically.

  • Base lead: 1 credit; email verification: +1 credit; phone verification: +1.5 credits
  • A fully verified lead (email + phone) costs 3.5 credits
Refunds are automatic You only pay for leads we deliver

What Happens to Each Result

Here's what Lead Titan does with each outcome of the deliverability check:

Check Result What It Means What Lead Titan Does
Deliverable The mailbox can receive mail Delivered
Catch-all The domain accepts any address, so the mailbox can't be confirmed Discarded
Unknown The check couldn't get a clear answer Discarded
Risky The address may not be safe to send to Discarded
Invalid The mailbox doesn't exist or can't receive mail Discarded
Role inbox (info@, sales@) A shared inbox, not a person Rejected

What Is a Catch-All Domain?

A catch-all domain is configured to accept email sent to any address at that domain, even if the specific mailbox doesn't exist. For example, anything@company.com would be accepted by the server. That means a deliverability check can't tell a real person's inbox apart from an address that goes nowhere.

Lead Titan doesn't deliver catch-all addresses. You may get fewer leads from catch-all domains, but every email you receive passed the check.

Why Verification Takes Minutes to Hours

Database tools return results instantly because they're returning old records. Lead Titan checks every contact for your order, so results arrive over minutes to hours:

You can watch results arrive live in the app as each lead passes verification. Quality, qualified leads take time.

What Happens to Leads We Can't Deliver?

When an email can't be confirmed as deliverable, the lead isn't delivered — and you aren't charged for it. Credits are reserved when you order, and credits for leads we can't deliver are refunded automatically.

You only pay for leads we deliver.

Frequently Asked Questions

Which emails does Lead Titan AI deliver?

Only emails that pass a mailbox-level deliverability check for your order. Catch-all, unknown, risky and invalid addresses are discarded, and generic role inboxes such as info@ and sales@ are rejected.

Why doesn't Lead Titan AI deliver catch-all emails?

A catch-all domain accepts mail for any address, so a deliverability check cannot confirm that a specific person's mailbox exists. Rather than hand you an address it cannot confirm, Lead Titan discards it.

Why do results take minutes to hours?

Each contact is checked for your order instead of being pulled from a stored export. First leads typically arrive within minutes, full orders usually take a few hours, and large or niche orders can take up to 24 hours. You can watch results arrive live in the app.

Do I pay for emails that fail verification?

No. Credits are reserved when you order, and credits for leads we can't deliver are refunded automatically. A base lead costs 1 credit, email verification adds 1 credit, and phone verification adds 1.5 credits, so a fully verified lead (email + phone) costs 3.5 credits.
