About u-system.cz

u-system.cz is a domain used by a company operating in the [industry] sector. The company's email domain is set up as a catchall, meaning that it can receive emails sent to non-existent addresses. This setup can make it difficult for traditional email verification services to accurately verify email addresses.

Challenges of Verifying Emails at u-system.cz

Verifying email addresses at u-system.cz can be challenging due to several reasons:

• Email Security Gateways: u-system.cz may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Setup: The domain's catchall setup 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 email addresses accurately.
• No Bounce Messages: Even if you send test messages to invalid email addresses at u-system.cz, the domain may not always return a bounce message, making services like Scrubby ineffective.

Risks of Not Verifying Emails at u-system.cz

Failing to verify email addresses at u-system.cz can lead to several risks:

• Risky Emails: Other services may leave most emails at u-system.cz as risky, leaving you unsure of how to handle 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.
• Outdated Lists: If you don't verify emails, your list will become outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately leading to lower delivery rates, open rates, and click rates. If the bounce rate is too high, your email service providers may restrict your account.
