When it comes to verifying emails from vslib.cz, businesses and marketers often face challenges. This domain, belonging to a Czech organization, presents unique obstacles in email verification due to its catchall setup and potential use of email security gateways. In this blog post, we'll explore the challenges of verifying emails from vslib.cz, the risks of not verifying them, and how BounceBan can help.

Understanding vslib.cz

vslib.cz is a Czech domain with a catchall setup, which means that it may accept all emails sent to it, regardless of whether the email address exists or not. This setup can make it difficult for traditional email verification services to accurately verify email addresses. Additionally, vslib.cz may use email security gateways, such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can further complicate the verification process.

Challenges of Verifying Emails from vslib.cz

Verifying emails from vslib.cz can be challenging due to several reasons:

• Catchall setup: vslib.cz's catchall setup makes it difficult for traditional email verification services to accurately verify email addresses. These services may not be able to distinguish between valid and invalid email addresses.
• Email security gateways: vslib.cz may use email security gateways, which can block or filter out verification attempts, making it difficult to determine the validity of an email address.
• Lack of bounce messages: vslib.cz may not always return a bounce message even if you send a test message to an invalid email address, making it difficult to determine whether an email address is valid or not.

Risks of Not Verifying Emails from vslib.cz

Not verifying emails from vslib.cz can result in several risks:

• High bounce rates: If you don't verify emails, you may end up sending emails to invalid addresses, which can lead to high bounce rates, damaging your sending reputation, and resulting in lower delivery rates, open rates, and click rates.
• Risky emails: Leaving most emails from vslib.cz as "risky" can lead to uncertainty about how to deal with them. If you keep them, you risk high bounce rates; if you delete them, you risk missing potentially valuable valid emails.
