Tianma.cn is the domain of 天马微电子股份有限公司 (Tianma Microelectronics Co., Ltd.), a Chinese company specializing in semiconductors. Located in Shenzhen, Guangdong, China, the company is a significant player in the semiconductor industry. When it comes to verifying email addresses from this domain, traditional email verification services often struggle due to the complexities involved. In this article, we'll explore the challenges of verifying emails at tianma.cn and how BounceBan can help overcome these obstacles.

Challenges of Verifying Emails at Tianma.cn

Verifying email addresses at tianma.cn can be a daunting task due to several reasons:

• Catchall Emails: Tianma.cn is known to use catchall emails, which means that the email server accepts all emails sent to it, regardless of whether the email address exists or not. This makes it difficult for traditional email verification services to determine the validity of an email address using simple SMTP tests.
• Email Security Gateways: There is a possibility that tianma.cn uses email security gateways (ESG) such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• No Bounce Messages: Even if you send test messages to an invalid email address at tianma.cn, the server may not return a bounce message, making it challenging to determine the email's validity.

Risks of Not Verifying Emails at Tianma.cn

Failing to verify email addresses at tianma.cn can lead to several risks:

• High Bounce Rates: If you don't verify emails, your list may contain invalid or non-existent email addresses, resulting in high bounce rates. This can damage your sending reputation and lower your delivery, open, and click rates.
• Missing Valuable Emails: If you delete all unverified emails, you may miss out on potentially valuable contacts. On the other hand, if you keep all emails, you risk seeing a high bounce rate.
• Account Restrictions: If your bounce rate is too high, your email service provider may restrict your account.
