Challenges of Verifying Emails from ulsan.ac.kr

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

• Email Security Gateways (ESG): There is no information on whether ulsan.ac.kr uses 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: ulsan.ac.kr 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 these emails.
• No Bounce Messages: Even if you send test messages to an invalid email address at ulsan.ac.kr, it may not always return a bounce message, making services like Scrubby ineffective.

Risks of Not Verifying Emails from ulsan.ac.kr

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

• High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately leading to lower delivery rates, open rates, and click rates.
• Restricted Account: If the bounce rate is too high, your email service providers may restrict your account.
• Missed Opportunities: If you delete all unverified emails, you risk missing potentially valuable contacts.
