Introduction

vbu.cn is a Chinese domain that is commonly used for business emails. With its growing presence in the industry, it's essential to have a reliable way to verify email addresses from this domain. In this blog post, we'll discuss the challenges of verifying emails from vbu.cn, the risks of not verifying them, and how BounceBan can help you overcome these challenges.

Challenges of Verifying Emails from vbu.cn

Verifying emails from vbu.cn can be challenging due to several reasons:

• Email Security Gateways (ESGs): vbu.cn may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to block simple SMTP tests, making it difficult for traditional verification services to verify emails.
• Catchall Emails: vbu.cn is set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter cannot verify these emails.
• No Bounce Messages: vbu.cn may not always return a bounce message even if you send test messages to an invalid email address at that domain, making services like Scrubby not work.

Risks of Not Verifying Emails from vbu.cn

Not verifying emails from vbu.cn can lead to several risks:

• Risky Emails: Other services may leave most emails at vbu.cn as risky, making it difficult to decide what to do with them. If you keep them, you risk seeing a high bounce rate, and if you delete them, you risk missing potentially valuable valid emails.
• Outdated Lists: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
