Verifying email addresses is a crucial step in maintaining a healthy email list and ensuring high deliverability rates. However, some domains can be challenging to verify, and ucl.com.tw is one of them. In this blog post, we'll discuss the challenges of verifying emails at ucl.com.tw, the risks of not verifying them, and how BounceBan can help you overcome these challenges.

Basic Information about ucl.com.tw

ucl.com.tw is a domain used by a company operating in the industry. The company has its address at [address]. One notable thing about this domain is that it uses a catchall email system, which means that it accepts all emails sent to its domain, regardless of whether the email address exists or not. This can make it difficult to verify email addresses using traditional methods.

Challenges of Verifying Emails at ucl.com.tw

Verifying email addresses at ucl.com.tw can be challenging due to several reasons:

• Catchall Email System: As mentioned earlier, ucl.com.tw uses a catchall email system, which makes it difficult to determine whether an email address is valid or not using simple SMTP tests. This is because the domain accepts all emails, making it hard to distinguish between valid and invalid email addresses.
• Email Security Gateways (ESG): There is a possibility that ucl.com.tw uses Email Security Gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it would make it even more challenging to verify email addresses using traditional methods.
• No Bounce Messages: Even if you send a test email to an invalid email address at ucl.com.tw, the domain may not return a bounce message, making it difficult to determine whether the email address is valid or not.

Risks of Not Verifying Emails at ucl.com.tw

Not verifying email addresses at ucl.com.tw can lead to several risks, including:

• High Bounce Rates: If you don't verify email addresses, you may end up sending emails to invalid addresses, resulting in high bounce rates. This can damage your sending reputation, leading to lower delivery rates, open rates, and click rates.
• Risky Emails: Other email verification services may leave most emails at ucl.com.tw as "risky," making it difficult to determine what to do with them. If you keep them, you risk seeing a high bounce rate, and if you delete them, you risk missing potentially valuable valid emails.
