What is a verified email address?

A verified email address is an email that has been checked for validity and deliverability. At Dropcontact, email verification is built directly into our enrichment process. Every email we find goes through real-time validation before being delivered to you.

Quick stats: Dropcontact achieves 99% validity for nominative emails and 90% validity for catch-all emails.

What does Dropcontact verify?

Email verification isn't just checking if an address looks right. Dropcontact runs multiple validation steps on every email:

✅ Syntax validation checks proper formatting (valid characters, correct structure)

✅ Domain validation verifies the domain exists and has active mail servers (MX records)

✅ Mailbox validation tests if the mailbox exists and can receive emails (using SMTP without sending actual messages)

✅ Catch-all handling uses proprietary algorithms to validate emails on catch-all domains where standard verifiers fail

What are catch-all domains? About 30% of B2B companies use catch-all configurations that accept all emails sent to their domain. These are often high-value enterprise targets that competitors skip because they're harder to verify.

Can I use Dropcontact to verify existing emails?

Yes. Dropcontact works as both an email finder and an email verifier.

When you upload a file with emails already filled in, Dropcontact automatically verifies every address:

• Verifies deliverability for each address
• Detects and corrects typos or formatting errors
• Validates catch-all domains using advanced algorithms
• Flags disposable or fake addresses
• Moves invalid emails to the Notes column for review

Result: Clean, verified emails ready to use, with no manual cleanup required.

Is Dropcontact's verification GDPR compliant?

Yes, fully compliant by design. Here's why:

🇪🇺 European servers. All infrastructure is hosted in Europe, meeting EU data protection requirements.

🚫 No personal data storage. We generate and verify emails in real-time using algorithms, not databases.

✅ No retention risks. Personal data isn't stored, so there's no risk of violating data retention regulations.

🔒 Privacy by design. Information is processed only when needed and isn't retained after verification.

This makes Dropcontact ideal for European companies and organizations with strict compliance requirements.

Should I use other verification tools after Dropcontact?

No. Adding third-party verifiers like Neverbounce, Zerobounce, or Bouncer actually reduces your results.

Here's what happens when you re-verify Dropcontact emails:

• Valid emails get mislabeled as "risky" (14-39% false positive rate)
• Your email coverage drops significantly
• Catch-all emails we validated get incorrectly flagged as "unknown"
• You lose deliverable addresses that would have worked

Why? Traditional verifiers rely on outdated databases and can't handle catch-all domains. They don't understand that Dropcontact's real-time algorithms have already validated these emails through advanced testing.

Our verification is optimized for the emails we generate. You get maximum accuracy without extra steps.

What do the email qualification levels mean?

Beyond verification, Dropcontact qualifies each email with a confidence level:

• nominative@pro = 99% valid → go for it 
• catchall@pro = 90% valid → usable in cold emails without risk

Why is Dropcontact's verification different?

Unlike traditional verifiers that rely on static databases, Dropcontact uses real-time algorithms for every verification:

Always current. No outdated database checks, every verification happens live.

Catch-all expertise. Advanced validation for the 30% of B2B companies that other tools skip.

Built-in, not added on. Verification is part of the enrichment process, not a separate step.

No database dependency. We don't store contact data, eliminating GDPR risks and data staleness.
