Verifying email addresses is a crucial step in maintaining a healthy email list and ensuring high deliverability rates. However, verifying emails from certain domains can be challenging, especially when they use email security gateways or are set to catchall. In this blog post, we will discuss the challenges of verifying emails from ysu.ac.kr, the domain of Youngsan University, and how BounceBan can help overcome these challenges.

About Youngsan University

Youngsan University is a higher education institution located in South Korea. The university's domain is ysu.ac.kr, and it uses the email pattern j.smith@ysu.ac.kr, which is the most common pattern, accounting for 20% of all email addresses. Other email patterns used by the university include js@ysu.ac.kr (13%), j.smith@ysu.ac.kr (9%), and johns@ysu.ac.kr (5%).

Challenges of Verifying Emails from ysu.ac.kr

Verifying emails from ysu.ac.kr can be challenging due to several reasons:

• Email Security Gateways: The university may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Emails: The university's email domain is set to catchall, which means that traditional verification services may not be able to verify emails from this domain.
• No Bounce Messages: Even if you send test messages to an invalid email address at ysu.ac.kr, the university's email system may not always return a bounce message, making it difficult for verification services to determine the validity of an email address.

Risks of Not Verifying Emails from ysu.ac.kr

Not verifying emails from ysu.ac.kr can lead to several risks, including:

• High Bounce Rates: If you don't verify emails, you may end up sending emails to invalid addresses, which can result in high bounce rates, damaging your sending reputation.
• Lower Delivery Rates: A high bounce rate can lead to lower delivery rates, open rates, and click rates, ultimately affecting your email marketing campaigns.
• Account Restrictions: If your bounce rate is too high, your email service provider may restrict your account.
