Verifying email addresses from specific domains can be a daunting task, especially when dealing with catchall emails. In this blog post, we will explore the challenges of verifying emails from tn.edu.tw, a domain used by Ying Hai Senior High School in Taiwan, and how BounceBan can help overcome these challenges.

About tn.edu.tw

Ying Hai Senior High School is a government administration institution located in Tainan City, Taiwan. The school's domain, tn.edu.tw, is used for official communication and email exchange. With a catchall email setup, the domain presents a unique challenge for email verification services.

Challenges of Verifying Emails at tn.edu.tw

Verifying emails at tn.edu.tw can be tricky due to several reasons:

• Email Security Gateways (ESGs): There is no information yet about whether tn.edu.tw uses email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it would make simple SMTP tests fail, making verification more difficult.
• Catchall Emails: The domain is set up to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter cannot verify these emails.
• No Bounce Messages: Even if you send test messages to an invalid email address at tn.edu.tw, the domain may not always return a bounce message, making services like Scrubby not work.

Risks of Not Verifying Emails at tn.edu.tw

Not verifying emails at tn.edu.tw can lead to several risks:

• Risky Emails: Other services may leave most emails at tn.edu.tw as risky, leaving you unsure of how to deal with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
• Outdated Lists: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lowering your delivery rate, open rate, and click rate. If the bounce rate is too high, your email services providers may restrict your account.
