As a security-focused organization, VN3.com.br takes email verification seriously, which is crucial for maintaining a clean and reliable email list. In this blog post, we'll discuss the challenges of verifying emails from VN3.com.br, the risks of not verifying them, and how BounceBan can help.

Challenges of Verifying Emails from VN3.com.br

Verifying emails from VN3.com.br can be challenging due to several reasons:

• Email Security Gateways (ESGs): VN3.com.br might use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. These gateways can make simple SMTP tests fail, making it difficult to verify emails.
• Catchall Emails: VN3.com.br is set to catchall, which means that simple SMTP tests used by traditional verification services may not work.
• No Bounce Messages: VN3.com.br might not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails from VN3.com.br

If you don't verify emails from VN3.com.br, you risk:

• High Bounce Rate: Unverified emails can lead to a high bounce rate, damaging your sending reputation and resulting in lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at VN3.com.br as risky, making it difficult to decide what to do with them. If you keep them, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
• Outdated Lists: Failing to verify emails can result in outdated lists, which can harm your email marketing campaigns and lead to account restrictions from email service providers.
