The $10,000 Problem with Standard Email Verification Tools

Most email verification services fail when they encounter catch-all domains. These are companies that accept emails sent to any address at their domain (@company.com). When your current email verification tool hits a catch-all domain, it marks the email as “unknown” or “risky” and moves on.

Here's what this costs you:

Lost Revenue from Unverified Emails

A typical 10,000-email list contains about 4,000 catch-all and accept-all addresses. Standard verifiers mark these as undeliverable, but 70% of them actually work. That’s 2,800 missed opportunities per campaign.

$9,800

lost per campaign (at $3.50 per email)

Wasted Marketing Spend

Email service providers charge you for every email sent, whether it bounces or not. When you can’t verify catch-alls properly, you either:

• Skip sending to them (lose potential customers)

• Send to unverified addresses (risk high bounce rates)

Competitive Disadvantage

Your competitors using standard email verification tools face the same problem. They can’t reach catch-all domains either.

EmailAddress.ai gives you exclusive access to verified contacts your competition can’t touch.

How EmailAddress.ai Solves the Catch-All Email Verification Problem

Unknown domains (new or uncommon email providers)

Role-based emails with delivery confirmation

Frequently Asked Questions

How is EmailAddress.ai different from other email verification services?

Most email verification tools give up when they encounter catch-all domains, marking them as “unknown” or “risky.” These domains actually contain 70% deliverable email addresses. EmailAddress.ai uses advanced technology to verify catch-all domains with 99% accuracy, giving you access to 40% more deliverable contacts than standard verifiers.

What is catch-all email verification and why is it important?

Catch-all domains accept emails sent to any address at their domain (@company.com). Many businesses use this configuration for flexibility. Standard verifiers can’t determine which specific addresses work, so they mark all catch-all emails as unverifiable. We use proprietary technology to test actual delivery without sending emails, confirming which catch-all addresses are valid.

How accurate is your email verification service?

Our overall verification accuracy is 99%. For standard email addresses, we achieve 99.5% accuracy. For catch-all and accept-all domains (which other services can’t verify), we maintain 98% accuracy. This is significantly higher than industry standards of 60-70% accuracy.

Our reverse social verification (currently in beta) matches email addresses with current LinkedIn profiles to verify job titles, companies, and employment status. This feature is perfect for sales teams who need to confirm prospect information before outreach campaigns. It’s included with Growth and Hyper plans.

How fast is your bulk email verification?

Processing speed depends on list size: Under 1,000 emails get instant results, 1,000-10,000 emails take 2-5 minutes, 10,000-100,000 emails take 10-30 minutes, and 100,000+ emails have custom processing times. Our servers can process up to 50,000 emails per minute while maintaining accuracy.

Do you integrate with email marketing platforms?

Yes, we integrate with all major email marketing platforms and CRMs including Mailchimp, Constant Contact, Salesforce, HubSpot, and many others. We also offer a REST API for custom integrations. Setup typically takes less than 10 minutes.

What happens to my data after verification?

Your email lists are automatically deleted from our servers after 30 days. We never store, share, or sell your contact information. All data transmission is encrypted with SSL/TLS, and we’re fully GDPR compliant with SOC 2 Type II certification.

Do you offer refunds if I'm not satisfied?

Yes, we offer a 30-day money-back guarantee on all monthly plans. For verification accuracy, we guarantee bounce rates under 3% when using our verified email lists. If your bounce rate exceeds 3%, we’ll refund your verification credits.
