As a sales or marketing professional, you understand the importance of maintaining a clean and accurate email list. But what happens when you're dealing with emails from a domain like zhengbang.com.cn, which uses a catchall setup? Traditional email verification services often struggle to verify emails from such domains, leaving you with a list of unverified emails that can lead to high bounce rates and damage to your sending reputation.

In this blog post, we'll explore the challenges of verifying emails at zhengbang.com.cn and introduce BounceBan, a reliable solution that can accurately verify catchall emails and emails behind Email Security Gateways.

About zhengbang.com.cn

Zhengbang is a brand identity and consultant company based in Beijing, China.

Challenges of Verifying Emails at zhengbang.com.cn

Verifying emails at zhengbang.com.cn can be challenging due to several reasons:

• Catchall setup: The domain is set up to accept all emails, making it difficult for traditional verification services to determine whether an email is valid or not.

• No bounce message: Even if you send a test email to an invalid address at zhengbang.com.cn, the domain may not always return a bounce message, making it difficult to determine whether the email is valid or not.

Risks of Not Verifying Emails at zhengbang.com.cn

Not verifying emails at zhengbang.com.cn can lead to several risks, including:

• High bounce rates: If you don't verify emails, you may end up sending emails to invalid addresses, leading to high bounce rates and damaging your sending reputation.
