Verifying email addresses can be a daunting task, especially when dealing with catchall emails from domains like wiso.uni-koeln.de. In this blog post, we'll explore the challenges of verifying emails from wiso.uni-koeln.de, the risks of not verifying them, and how BounceBan can help you overcome these obstacles.
Understanding wiso.uni-koeln.de
Wiso.uni-koeln.de is a domain associated with the University of Cologne, a renowned institution in Germany. The domain is used for various academic and administrative purposes, including email communication. One of the unique aspects of this domain is that it is set up as a catchall, which can make email verification challenging.
Challenges of Verifying Emails at wiso.uni-koeln.de
Verifying emails from wiso.uni-koeln.de can be tricky due to several reasons:
- Catchall setup: As mentioned earlier, wiso.uni-koeln.de is set up as a catchall, which means that simple SMTP tests used by traditional verification services may not work. This setup can lead to inaccurate results or false positives.
- Email security gateways: There is a possibility that wiso.uni-koeln.de uses email security gateways like Cisco Secure Email (ESA), Barracuda, or Proofpoint, which can make simple SMTP tests fail.
- No bounce message: Even if you send a test message to an invalid email address at wiso.uni-koeln.de, it may not always return a bounce message, making it difficult for services like Scrubby to verify the email.
Risks of Not Verifying Emails at wiso.uni-koeln.de
Not verifying emails from wiso.uni-koeln.de can lead to several risks:
- High bounce rate: If you don't verify emails, your list may be outdated, resulting in a high bounce rate, which can damage your sending reputation and lower your delivery rate, open rate, and click rate.
- Risky emails: Other services may leave most emails at wiso.uni-koeln.de 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.
