Verifying emails from the wch.cn domain can be a daunting task, especially when dealing with catchall emails and email security gateways. In this blog post, we will explore the challenges of verifying emails from wch.cn and how BounceBan can help overcome these challenges.

About wch.cn

wch.cn is the domain of 南京沁恒电子有限公司 (Nanjing Qinheng Electronics Co., Ltd.), a wholesale company based in Nanjing, Jiangsu Province, China. The company's email domain is configured to use catchall, which means that all emails sent to non-existent addresses will be caught by a single mailbox. This can make it difficult for traditional email verification services to accurately verify emails from this domain.

Challenges of Verifying Emails from wch.cn

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

• Catchall Emails: As mentioned earlier, wch.cn is configured to use catchall, which means that traditional email verification services that use simple SMTP tests will not be able to verify these emails accurately.
• Email Security Gateways: There is a possibility that wch.cn uses email security gateways such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to protect their email system. These gateways can make it difficult for traditional email verification services to verify emails accurately.
• Lack of Bounce Messages: Even if you send test messages to an invalid email address at wch.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 from wch.cn

Not verifying emails from wch.cn can result in several risks, including:

• High Bounce Rate: If you don't verify emails, your email list may contain invalid or non-existent emails, which can lead to a high bounce rate. This can damage your sending reputation and lower your delivery rate, open rate, and click rate.
• Risky Emails: If you don't verify emails, you may end up with a list of risky emails that can harm your email campaign. Other services may leave most emails at wch.cn as risky, leaving you unsure of how to deal with them.
