Introduction

Verifying emails from zera.cz can be a daunting task, especially when dealing with catchall emails. Catchall emails are email addresses that are not assigned to a specific user but instead catch all emails sent to a particular domain. In this blog post, we will discuss the challenges of verifying emails from zera.cz, the risks of not verifying emails, and how BounceBan can help you overcome these challenges.

Challenges of Verifying Emails from zera.cz

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

• Email Security Gateways (ESGs): zera.cz may use ESGs such as Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos, which can make simple SMTP tests fail.
• Catchall Emails: zera.cz may be set to catchall, which means that simple SMTP tests used by traditional verification services may not be able to verify the emails.
• Lack of Bounce Messages: zera.cz may not always return a bounce message even if you send test messages to an invalid email address, making services like Scrubby not work.

Risks of Not Verifying Emails

Not verifying emails from zera.cz can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list will be outdated, and you may risk seeing a high bounce rate, damaging your sending reputation, and as a result, lower delivery rate, open rate, and click rate.
• Risky Emails: Other services may leave most emails at zera.cz as risky, so you don't know how to deal with it - if you keep the emails, you may risk seeing a high bounce; if you delete all of them, you risk missing the potentially valuable valid emails.
