Email verification: Does Dropcontact check emails I already have?

Yes! Dropcontact automatically verifies and validates every email address in your file, including the ones you already have.

What happens during verification?

When you process a file with existing email addresses, Dropcontact:

✅ Verifies deliverability – Checks if the email can actually receive messages
✅ Detects incorrect formats – Identifies typos, invalid domains, or syntax errors
✅ Handles catch-all domains – Uses advanced algorithms to validate emails on catch-all servers (where standard verifiers often fail)
✅ Flags fake emails – Detects disposable or role-based addresses that shouldn't be used for outreach

How corrections work

If an email in your file is wrong or invalid, Dropcontact automatically:

• Corrects it when possible (e.g., fixing typos or finding the right format)
• Moves fake/invalid emails to the "Notes" column so you can review them without losing data

This means you get clean, verified emails ready to use, without manual cleanup.

Why Dropcontact's verification stands out

Unlike standalone email verifiers that rely on static databases, Dropcontact uses real-time algorithms to verify every email. This means:

• Always up-to-date validation – No outdated database checks, every verification happens in real-time
• Superior catch-all handling – Our proprietary technology accurately validates catch-all emails where traditional verifiers fail or mark them as "unknown"
• Built-in, not bolted-on – Email verification is natively integrated into the enrichment process, not an afterthought
• 86% valid email rate – The highest accuracy in the industry
• Zero database dependency – We don't store or rely on outdated contact databases

⚠️ Important: Don't re-verify Dropcontact emails

Adding third-party verifiers like Neverbounce, Zerobounce, or Bouncer after Dropcontact will actually hurt your results.

Here's what happens when you run Dropcontact emails through other verifiers:

• They mislabel valid Dropcontact emails as "risky" (14-39% false positive rate)
• Your overall coverage drops significantly
• You lose deliverable emails that would have worked perfectly
• Catch-all emails that Dropcontact validated get incorrectly flagged as "unknown" or "risky"

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 Traditional verifiers rely on outdated databases and can't handle catch-all domains properly.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

Our analysis on 2,500 validated email addresses proves that Dropcontact-verified emails perform better when used directly, without additional verification layers.

The result? Higher accuracy, better deliverability, and more emails you can confidently use for outreach.
