In this blog post, we will discuss the challenges of verifying emails at vzuplzen.cz and how BounceBan can help you overcome these challenges.

About vzuplzen.cz

vzuplzen.cz is the domain of VZU Plzen, a research organization based in Plzeň, Czech Republic. The domain is set up to catchall, which means that it may not always return a bounce message even if you send a test message to an invalid email address. This setup can make it difficult for traditional verification services to accurately verify email addresses.

Challenges of Verifying Emails at vzuplzen.cz

Verifying emails at vzuplzen.cz can be challenging due to several reasons:

• Catchall Setup: The domain is set up to catchall, which means that simple SMTP tests used by traditional verification services may not work.
• Email Security Gateways: There is a possibility that vzuplzen.cz uses email security gateways (ESGs) like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• No Bounce Messages: The domain may not always return a bounce message even if you send a test message to an invalid email address, making it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at vzuplzen.cz

Not verifying emails at vzuplzen.cz can lead to several risks, including:

• High Bounce Rate: If you don't verify emails, your list may be outdated, resulting in a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate.
