However, verifying emails from specific domains like yonker.cn can be a daunting task, especially when dealing with catchall emails. In this article, we'll explore the challenges of verifying emails from yonker.cn, the risks of not verifying them, and how BounceBan can help you overcome these challenges.

About Yonker.cn

Yonker Medical, a medical devices company based in Xuzhou, Jiangsu, China, uses the domain yonker.cn for their email communications. With a significant portion of their email addresses being catchall, verifying these emails can be a challenge.

Challenges of Verifying Emails at Yonker.cn

Verifying emails from yonker.cn can be tricky due to several reasons:

• Email Security Gateways: Yonker.cn may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Emails: Yonker.cn's email pattern distribution suggests that a significant portion of their emails are catchall, which cannot be verified using traditional verification services.
• Lack of Bounce Messages: Even if you send test messages to an invalid email address at yonker.cn, it may not always return a bounce message, making it difficult for services like Scrubby to verify the email.

Risks of Not Verifying Emails at Yonker.cn

Not verifying emails from yonker.cn can lead to:

• High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at yonker.cn as risky, leaving you unsure of how to handle 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.
