Verifying emails from zcm.cz can be a daunting task, especially when dealing with catchall emails and email security gateways. In this blog post, we'll explore the challenges of verifying emails at zcm.cz and how BounceBan can help you overcome these obstacles.

Basic Information about zcm.cz

zcm.cz is a domain that uses a catchall email system, which means that all emails sent to non-existent email addresses will be accepted by the mail server. The most common email pattern at zcm.cz is john.smith@zcm.cz, which accounts for 28% of all email patterns.

Challenges of Verifying Emails at zcm.cz

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

• Catchall Emails: zcm.cz uses a catchall email system, which makes it difficult for traditional email verification services to verify emails. Simple SMTP tests used by services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work, as they rely on bounce messages to verify emails.
• Email Security Gateways: zcm.cz may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. These gateways can make simple SMTP tests fail, making it difficult to verify emails.
• No Bounce Messages: zcm.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 at zcm.cz

Not verifying emails at zcm.cz can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list will be outdated, and you'll see a high bounce rate, damaging your sending reputation. This can result in a lower delivery rate, open rate, and click rate. If the bounce rate is too high, your email service providers may restrict your account.
• Missed Opportunities: If you delete all unverified emails, you risk missing potentially valuable valid emails.
