Challenges of Verifying Emails from zfu.ch

Verifying emails from zfu.ch can be challenging due to several reasons:

• Catchall Emails: zfu.ch uses catchall emails, which can make it difficult for traditional verification services to verify them accurately. Catchall emails are email addresses that are not specifically assigned to a user but instead catch all emails sent to a domain.
• Email Security Gateways: zfu.ch may use email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. These gateways can make it difficult for verification services to verify emails using simple SMTP tests.
• Lack of Bounce Messages: zfu.ch may not always return a bounce message even if you send a test message to an invalid email address. This can make it difficult for services like Scrubby to verify emails.

Risks of Not Verifying Emails from zfu.ch

Not verifying emails from zfu.ch can lead to several risks:

• High Bounce Rate: If you don't verify emails, your list will be outdated, resulting in a high bounce rate, damaging your sending reputation, and lowering your delivery rate, open rate, and click rate.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