Ulsan College, a higher education institution, uses the domain uc.ac.kr for its email communications. As an organization that deals with a large volume of emails, verifying email addresses is crucial to maintain a healthy email list and prevent bounces. In this blog post, we will discuss the challenges of verifying emails at uc.ac.kr, the risks of not verifying emails, and how BounceBan can help overcome these challenges.

Challenges of Verifying Emails at uc.ac.kr

Verifying emails at uc.ac.kr can be challenging due to several reasons. Firstly, there is no information available about whether the domain uses email security gateways (ESG) such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If it does, it would make simple SMTP tests fail, making it difficult to verify emails.

Secondly, the domain is set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails. Catchall emails are a common practice in many organizations, and it's estimated that approximately 40-50% of business emails are catchalls.

Lastly, the domain may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails at uc.ac.kr

Not verifying emails at uc.ac.kr can lead to several risks. Other services may leave most emails at uc.ac.kr as risky, leaving you uncertain about how to deal with them. If you keep the emails, you may risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.

If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and subsequently, lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email services providers may restrict your account.
