Verifying email addresses from specific domains can be a challenging task, especially when dealing with catchall emails. In this blog post, we'll focus on the upc.com.tw domain, which is associated with UPC Chemicals (M) Sdn Bhd, a chemical company based in Malaysia. We'll discuss the challenges of verifying emails from this domain, the risks of not verifying them, and how BounceBan can help you overcome these challenges.
About upc.com.tw
UPC Chemicals (M) Sdn Bhd is a chemical company based in Kuantan, Pahang, Malaysia. The company operates under the domain upc.com.tw, which is a catchall domain, meaning that it accepts all emails sent to it, regardless of whether the email address exists or not. This makes it difficult to verify email addresses from this domain using traditional verification services.
Challenges of Verifying Emails from upc.com.tw
Verifying email addresses from upc.com.tw can be challenging due to several reasons:
- Catchall Domain: upc.com.tw is a catchall domain, which means that it accepts all emails sent to it, making it difficult to determine whether an email address is valid or not.
- Email Security Gateways: There is a possibility that upc.com.tw uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. If this is the case, simple SMTP tests used by traditional verification services may fail.
- Lack of Bounce Messages: upc.com.tw may not always return a bounce message even if you send a test message to an invalid email address, making it difficult for services like Scrubby to verify emails.
Risks of Not Verifying Emails from upc.com.tw
Not verifying email addresses from upc.com.tw can lead to several risks, including:
- High Bounce Rate: If you don't verify emails, you may end up sending emails to invalid addresses, which can lead to a high bounce rate. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates.
- Risky Emails: Other services may leave most emails from upc.com.tw as "risky," making it difficult to determine how to deal 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.
