Verifying email addresses is a crucial step in maintaining a healthy email list and ensuring the success of your email marketing campaigns. However, verifying catchall emails can be a significant challenge, especially when dealing with domains like upba.cz. In this blog post, we'll explore the challenges of verifying emails at upba.cz, the risks of not verifying them, and how BounceBan can help you overcome these challenges.

About upba.cz

upba.cz is a domain used by a company in the industry. While we don't have more information about the company, we know that their email domain is set to catchall, which means that all emails sent to non-existent addresses within the domain will be caught by a single mailbox. This setup can make email verification more complex.

Challenges of Verifying Emails at upba.cz

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

• Email Security Gateways (ESGs): upba.cz might use ESGs like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. to filter out unwanted emails. If this is the case, traditional verification services may fail to verify emails using simple SMTP tests.
• Catchall Setup: As mentioned earlier, upba.cz is set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter might not be able to verify emails accurately.
• No Bounce Messages: upba.cz might not always return a bounce message even if you send test messages to an invalid email address at that domain. This can make it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails at upba.cz

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

• Risky Emails: Other services might leave most emails at upba.cz as risky, leaving you unsure of how to handle them. If you keep them, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
• Outdated Lists: Failing to verify emails can lead to outdated lists, resulting in high bounce rates, damaging your sending reputation, and ultimately affecting your delivery rate, open rate, and click rate. If the bounce rate is too high, your email service providers may restrict your account.
