As a sales and marketing professional, you understand the importance of having accurate and reliable email lists. However, verifying emails from certain domains can be a challenge, especially when it comes to catchall emails. In this blog post, we'll discuss the challenges of verifying emails from topsailing.com.cn, a management consulting company based in Shenzhen, China, and how BounceBan can help you overcome these challenges.

About topsailing.com.cn

topsailing.com.cn is the domain of 深圳甲子启航投资有限公司 (Shenzhen Jiazi Qihang Investment Co., Ltd.), a management consulting company based in Shenzhen, Guangdong, China. The company's email domain is set to catchall, which means that it can be difficult to verify email addresses from this domain using traditional verification services.

Challenges of Verifying Emails from topsailing.com.cn

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

• Email Security Gateways: There is no information yet about whether topsailing.com.cn uses email security gateways (ESG) to filter out unwanted emails. If they do, it can make simple SMTP tests fail, making it difficult to verify email addresses.
• Catchall Emails: topsailing.com.cn's email domain is set to catchall, which means that simple SMTP tests used by traditional verification services may not work. Catchall emails can be problematic because they can accept any email address, making it difficult to determine whether an email address is valid or not.
• No Bounce Messages: topsailing.com.cn may not always return a bounce message even if you send a test message to an invalid email address. This can make it difficult for verification services that rely on bounce messages to verify email addresses.

Risks of Not Verifying Emails from topsailing.com.cn

Not verifying emails from topsailing.com.cn can lead to several risks:

• High Bounce Rate: If you don't verify emails, you may end up with a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate.
• Missed Opportunities: If you delete all unverified emails, you may miss out on potentially valuable leads. On the other hand, if you keep all unverified emails, you may risk sending emails to invalid addresses, which can lead to a high bounce rate.
• Outdated Lists: If you don't verify emails regularly, your lists can become outdated, leading to a high bounce rate and damaged sending reputation.
