Challenges of Verifying Emails from zem.uni-bonn.de
Verifying emails from zem.uni-bonn.de can be challenging due to several reasons:
- Catchall Emails: zem.uni-bonn.de is set up to receive catchall emails, which means that any email address that doesn't exist will still be accepted by the mail server. This makes it difficult to determine whether an email address is valid or not.
- Email Security Gateways: It's unclear whether zem.uni-bonn.de uses email security gateways like Cisco Secure Email (ESA), Barracuda, Proofpoint, Abnormal Security, Mimecast, SpamTitan, Checkpoint, Forrester, Sophos, etc. If they do, it will make simple SMTP tests fail, making email verification even more challenging.
- Lack of Bounce Messages: zem.uni-bonn.de may not always return a bounce message even if you send a test message to an invalid email address, making it difficult for traditional email verification services to work.
Risks of Not Verifying Emails
Not verifying emails from zem.uni-bonn.de can lead to several risks, including:
- High Bounce Rates: If you don't verify emails, you risk sending emails to invalid addresses, which can lead to high bounce rates, damaging your sending reputation, and resulting in lower delivery rates, open rates, and click rates.
- Outdated Lists: Failing to verify emails means your list will be outdated, leading to poor email campaign performance and wasted resources.
