About zdns.cn

zdns.cn is a company operating in the information technology and services industry, based in Beijing, China. Their domain, zdns.cn, is configured to use email security gateways (ESGs), which can make email verification more complicated. Moreover, their email pattern distribution suggests that 28% of their emails follow the format john.smith@zdns.cn, while 16% follow the format j.smith@zdns.cn.

Challenges of Verifying Emails at zdns.cn

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

• Email Security Gateways (ESGs): zdns.cn may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. These gateways can make simple SMTP tests fail, making it difficult for traditional verification services to verify emails.
• Catchall Emails: zdns.cn is configured to use catchall emails, which can make it difficult for traditional verification services to verify emails. Catchall emails are emails that are not explicitly defined in the email system, making it challenging to determine whether they are valid or not.
• No Bounce Messages: Even if you send a test message to an invalid email address at zdns.cn, it may not always return a bounce message, making it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at zdns.cn

Not verifying emails at zdns.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. This can damage your sending reputation, 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 sending reputation. Other services may leave most emails at zdns.cn as risky, making it difficult to determine how to deal with them.
