The University of Science and Technology of Korea, commonly referred to as UST, is a prestigious institution of higher learning that specializes in the fields of science, technology, engineering, and mathematics (STEM). With a strong focus on research and innovation, UST has established itself as a leading academic institution in South Korea. In this blog post, we will explore the challenges of verifying emails from the ust.ac.kr domain and how BounceBan can help overcome these challenges.

Challenges of Verifying Emails at ust.ac.kr

Verifying emails at ust.ac.kr can be a daunting task due to several reasons. Firstly, there is no information available on 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 can make simple SMTP tests fail, making it difficult to verify emails.

Secondly, the ust.ac.kr domain is set to catchall, which means that traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify emails accurately. Catchall emails are a type of email that accepts all emails sent to a specific domain, regardless of whether the email address exists or not. This makes it difficult to determine whether an email address is valid or not.

Lastly, the ust.ac.kr domain may not always return a bounce message even if you send a test message to an invalid email address, making services like Scrubby not work. This can lead to inaccurate email verification results.

Risks of Not Verifying Emails at ust.ac.kr

Not verifying emails at ust.ac.kr can lead to several risks. For instance, other services may leave most emails at ust.ac.kr as risky, leaving you unsure of how to deal with them. If you keep the emails, you may risk seeing a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate. On the other hand, if you delete all the emails, you risk missing potentially valuable valid emails.

Moreover, if you don't verify emails, your list will be outdated, resulting in a high bounce rate, which can lead to your email services providers restricting your account.

Why BounceBan is the Best Choice for Verifying Emails at ust.ac.kr

BounceBan is the only service capable of reliably verifying catchall emails and emails behind Email Security Gateways. Services such as Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter are unable to verify catchall emails.

Approximately 40-50% (increasing overtime) of business emails are catchalls, which are not verifiable by other services. BounceBan, however, can accurately verify over 80% of these emails with a 97%+ accuracy rate. Catchall emails that cannot be verified with certainty will be tagged as 'risky', accounting for about 20% or less.

BounceBan's success rate in verifying catchall emails is on a consistent upward trajectory. It verifies millions of emails daily and leverages advanced AI to recognize patterns and enhance accuracy.

BounceBan verification is fast, taking only a few seconds for most emails. For a small share of catchall emails, it may take a few minutes. You can verify thousands of emails concurrently.

BounceBan never has to actually send an email to verify the email, unlike Scrubby, which sends test emails to verify email addresses. This makes BounceBan completely compliant with GDPR, eliminating the risk of sending unwanted emails.
