Introduction to ynnu.edu.cn

Yunnan Normal University, located in Shanghai, China, is a prominent institution in the education management industry. With its domain ynnu.edu.cn, the university has a significant online presence. However, verifying email addresses from this domain can be a challenge, especially when it comes to catchall emails. In this blog post, we will explore the challenges of verifying emails at ynnu.edu.cn and how BounceBan can help overcome these obstacles.

Challenges of Verifying Emails at ynnu.edu.cn

Verifying emails at ynnu.edu.cn can be a daunting task due to several reasons:

• Email Security Gateways (ESGs): There is a possibility that ynnu.edu.cn uses ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If this is the case, simple SMTP tests used by traditional verification services may fail.
• Catchall Emails: ynnu.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 emails accurately.
• No Bounce Messages: Even if you send test messages to an invalid email address at ynnu.edu.cn, the domain may not always return a bounce message, making it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at ynnu.edu.cn

If you don't verify emails at ynnu.edu.cn, you may face the following risks:

• High Bounce Rate: Not verifying emails can lead to a high bounce rate, damaging your sending reputation and resulting in lower delivery rates, open rates, and click rates.
• Outdated Lists: Failing to verify emails can lead to outdated lists, which can further exacerbate the bounce rate issue.
• Account Restrictions: If your bounce rate is too high, your email service providers may restrict your account.
