Challenges of Verifying Emails at usi.com.hk

Verifying emails at usi.com.hk can be challenging due to several reasons:

• Email Security Gateways (ESGs): usi.com.hk may use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc., which can make simple SMTP tests fail. This makes it difficult for traditional verification services to accurately verify emails.
• Catchall Emails: Since usi.com.hk is set to catchall, simple SMTP tests used by traditional verification services may not be able to verify emails. Services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not be able to verify catchall emails, leading to inaccurate results.
• No Bounce Messages: usi.com.hk may not always return a bounce message even if you send a test message to an invalid email address. This makes it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at usi.com.hk

Not verifying emails at usi.com.hk can lead to several risks:

• High Bounce Rates: If you don't verify emails, your email list may be outdated, leading to high bounce rates. This can damage your sending reputation, resulting in lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at usi.com.hk as risky, making it difficult to decide what to do with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
