As businesses expand their reach, verifying email addresses has become a crucial step in maintaining a healthy email list. One such domain that requires attention is topys.cn, a prominent player in the information technology and services industry. In this article, we'll delve into the challenges of verifying emails from topys.cn, the risks of not doing so, and how BounceBan can help you overcome these obstacles.

About topys.cn

Topys is a Chinese company operating in the information technology and services sector. With its headquarters located in Shenzhen, Guangdong, China, the company has established itself as a significant player in the industry. When it comes to email addresses, topys.cn has a catchall setup, which means that all emails sent to non-existent addresses within the domain will be received by the catchall mailbox. This setup can make email verification a daunting task.

Challenges of Verifying Emails from topys.cn

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

• Catchall Setup: Topys.cn has a catchall setup, which makes it difficult for traditional verification services to accurately verify email addresses. These services often rely on simple SMTP tests, which can fail when dealing with catchall emails.
• Email Security Gateways: Although it's unclear whether topys.cn uses email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., it's essential to consider the possibility. ESGs can make simple SMTP tests fail, making verification even more challenging.
• Lack of Bounce Messages: Topys.cn may not always return a bounce message even when an email is sent to an invalid address. This lack of response can make it difficult for services like Scrubby to verify emails accurately.

Risks of Not Verifying Emails from topys.cn

Failing to verify emails from topys.cn can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, your list may contain invalid addresses, resulting in high bounce rates. This can damage your sending reputation, leading to lower delivery rates, open rates, and click rates.
• Restricted Email Services: If your bounce rate is too high, your email service provider may restrict your account, limiting your ability to send emails effectively.
• Outdated Lists: Unverified email lists can become outdated, making it difficult to maintain a healthy and engaged email list.
