Union Corporation, a prominent player in its industry, operates under the domain union21.co.kr. With a significant presence in the market, it's essential to ensure that email communication with the company is accurate and reliable. However, verifying email addresses at union21.co.kr can be a challenge, especially when it comes to catchall emails.

Challenges of Verifying Emails at union21.co.kr

Verifying email addresses at union21.co.kr is not a straightforward task. There are several obstacles that traditional email verification services face when dealing with this domain. Firstly, it's unclear whether union21.co.kr uses email security gateways (ESG) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, and others. If they do, it would make simple SMTP tests fail, rendering traditional verification methods ineffective.

Another challenge is that union21.co.kr may be set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter would not be able to verify the emails. Moreover, the domain may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby ineffective.

Risks of Not Verifying Emails at union21.co.kr

Failing to verify emails at union21.co.kr can have significant consequences. Other services may flag most emails from this domain as risky, leaving you unsure of how to proceed. If you choose to keep the emails, you risk experiencing a high bounce rate, while deleting them might result in missing out on potentially valuable contacts. An unverified email list can lead to a high bounce rate, damaging your sending reputation and ultimately affecting your delivery rate, open rate, and click rate. In extreme cases, your email service providers might restrict your account.
