Verifying email addresses is a crucial step in maintaining a healthy email list and ensuring successful email campaigns. However, verifying emails from specific domains can be challenging, especially when it comes to catchall emails. In this blog post, we'll explore the challenges of verifying emails from zi.ku.dk and how BounceBan can help.

Basic Information about zi.ku.dk

zi.ku.dk is a domain used by the University of Copenhagen, a public research university located in Copenhagen, Denmark. The university is known for its academic excellence, particularly in the fields of natural sciences, humanities, and social sciences.

Challenges of Verifying Emails at zi.ku.dk

Verifying emails from zi.ku.dk can be challenging due to several reasons:

• Email Security Gateways (ESGs): It's unclear whether zi.ku.dk uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, or Sophos. If they do, it can make simple SMTP tests fail, making it difficult to verify emails.
• Catchall Emails: zi.ku.dk may be set to catchall, which means that simple SMTP tests used by traditional verification services like Emailable, NeverBounce, ZeroBounce, DeBounce, SendGrid, Snov, RocketReach, and Hunter may not work.
• No Bounce Messages: Even if you send test messages to an invalid email address at zi.ku.dk, it may not always return a bounce message, making services like Scrubby not work.

Risks of Not Verifying Emails at zi.ku.dk

Not verifying emails from zi.ku.dk can lead to:

• High Bounce Rates: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and ultimately affecting your delivery rate, open rate, and click rate.
• Risky Emails: Other services may leave most emails at zi.ku.dk as risky, leaving you unsure of how to deal with them. If you keep the emails, you risk seeing a high bounce rate; if you delete all of them, you risk missing potentially valuable valid emails.
