Finding Verified Email Addresses for Lead Generation

The Danger of Scraped Data

Building a list of email addresses is easy. Building a list of accurate email addresses is incredibly difficult. Many cheap data providers simply scrape the web and hand you outdated, dead, or "catch-all" email addresses.

If you load these unverified emails into your sending sequence, your bounce rate will skyrocket.

The Bounce Rate Threshold

Email providers like Google carefully monitor your bounce rate. If you consistently email addresses that do not exist, Google assumes you are a spammer guessing at email combinations. If your bounce rate climbs above 2-3%, your sender reputation takes a massive hit.

Real-Time Verification is Mandatory

You cannot rely on static databases. People change jobs, companies rebrand, and email formats shift. To protect your lead generation infrastructure, you must use a data provider that verifies the email address in real-time via an SMTP handshake directly before you download the list.

A smaller list of perfectly verified contacts will always outperform a massive list of risky data.
