Verifying email addresses is a crucial step in maintaining a healthy email list, especially when dealing with domains like vnol.cz. As a leading company in the Czech Republic, vnol.cz presents unique challenges when it comes to email verification. In this article, we'll explore the difficulties of verifying emails at vnol.cz, the risks of not verifying, and how BounceBan can help overcome these obstacles.

Understanding vnol.cz

vnol.cz is a Czech-based company operating in the industry. With its headquarters located in the Czech Republic, the company has established a strong presence in the region. When it comes to email addresses, vnol.cz uses a catchall domain, which means that all emails sent to non-existent addresses within the domain will still be received by the server.

The Challenges of Verifying Emails at vnol.cz

Verifying emails at vnol.cz can be a daunting task due to several reasons:

• Email Security Gateways (ESGs): There is no information yet about whether vnol.cz uses ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it will be a significant challenge for traditional verification services.
• Catchall Domain: vnol.cz is a catchall domain, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter will not work.
• No Bounce Messages: Even if you send test messages to an invalid email address at vnol.cz, the server may not always return a bounce message, making services like Scrubby ineffective.

The Risks of Not Verifying Emails at vnol.cz

Failing to verify emails at vnol.cz can lead to:

• High Bounce Rates: If you don't verify emails, your list will become outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately, lower delivery rates, open rates, and click rates.
• Risky Emails: Other services may leave most emails at vnol.cz as risky, leaving you uncertain about what to do with them. If you keep them, you risk seeing a high bounce rate; if you delete them, you risk missing potentially valuable valid emails.
