Understanding zena.cz and the Challenges of Verifying Emails

Zena.cz is a domain that poses unique challenges when it comes to verifying email addresses. With its catchall email setup, traditional email verification services often struggle to accurately verify email addresses. In this article, we'll delve into the challenges of verifying emails at zena.cz and explore how BounceBan can help overcome these obstacles.

Challenges of Verifying Emails at zena.cz

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

• Email Security Gateways (ESGs): There is a possibility that zena.cz uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. This can cause simple SMTP tests to fail, making it difficult for traditional verification services to verify emails accurately.
• Catchall Emails: Zena.cz uses a catchall email setup, which means that simple SMTP tests used by traditional verification services may not be able to verify emails accurately. Catchall emails are a common setup in many organizations, and traditional verification services often struggle to verify them accurately.
• Lack of Bounce Messages: Zena.cz may not always return a bounce message even if you send a test message to an invalid email address. This can make it difficult for services like Scrubby to verify emails accurately.

Risks of Not Verifying Emails at zena.cz

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

• High Bounce Rates: If you don't verify emails, your email list may contain a high percentage of invalid or non-existent email addresses, leading to high bounce rates and damaging your sending reputation.
• Lower Delivery Rates: A high bounce rate can lead to lower delivery rates, open rates, and click rates, ultimately affecting your email marketing campaigns.
• Account Restrictions: If your bounce rate is too high, your email service providers may restrict your account, making it difficult to send emails to your subscribers.
