Introduction

Yunnan University, a renowned institution in education management, uses the domain ynu.edu.cn for its email communication. With a large number of students, faculty members, and staff, verifying email addresses from this domain can be a daunting task. In this blog post, we will explore the challenges of verifying emails from ynu.edu.cn, the risks of not verifying them, and how BounceBan can help you verify catchall emails from this domain with ease.

Challenges of Verifying Emails from ynu.edu.cn

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

• Email Security Gateways (ESG): Ynu.edu.cn may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Emails: Ynu.edu.cn is set to catchall, which means that traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify these emails.
• Lack of Bounce Messages: Ynu.edu.cn may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby ineffective.

Risks of Not Verifying Emails from ynu.edu.cn

Not verifying emails from ynu.edu.cn can lead to:

• High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in high bounce rates, damaging your sending reputation, and lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at ynu.edu.cn as risky, making it difficult to decide what to do with them. If you keep them, you risk seeing high bounce rates, and if you delete them, you risk missing potentially valuable valid emails.
