About ynau.edu.cn

ynau.edu.cn is the domain of Yunnan Agricultural University, a higher education institution located in Kunming, Yunnan, China. The university's email domain is set to catchall, which means that it may not always return a bounce message even if you send a test message to an invalid email address.

Challenges of Verifying Emails from ynau.edu.cn

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

• Email Security Gateways: ynau.edu.cn may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. This can make it difficult for traditional verification services to verify emails using simple SMTP tests.
• Catchall Emails: ynau.edu.cn is set to catchall, which means that simple SMTP tests used by traditional verification services may not be able to verify emails. Catchall emails are a common practice in many organizations, and approximately 40-50% of business emails are catchalls.
• No Bounce Messages: ynau.edu.cn may not always return a bounce message even if you send a test message to an invalid email address. This can make it difficult for services like Scrubby, which verify emails by sending test messages, to accurately verify emails.

Risks of Not Verifying Emails from ynau.edu.cn

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

• High Bounce Rates: If you don't verify emails, your list will be outdated, and you may see a high bounce rate, damaging your sending reputation and resulting in lower delivery rates, open rates, and click rates.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 ynau.edu.cn as risky, leaving you unsure of how to deal with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
